Despite the efficiencies gained through technological advances and hardware consolidation in recent years, research from IDC shows that the old 80-20 rule still applies to most IT departments: 76.8 percent of time and resources are devoted to maintaining the environment, while the remaining 23.2 percent are spent on strategic initiatives that deliver actual business value.
How is this possible? Various components of the IT infrastructure are still managed in technological and organizational silos. Silos drive up costs because provisioning, deploying and updating new solutions require more time and personnel. Added layers of complexity and compatibility issues make the environment less flexible and more difficult to operate and scale. Virtual server sprawl creates performance issues and administrative headaches, which often lead to unnecessary upgrades and overprovisioning.
Converged infrastructure simplifies the IT environment by delivering compute, networking, storage access and virtualization resources in one preconfigured, pretested solution. The reduced complexity of a converged infrastructure that shares the same pool of resources brings a number of benefits:
- Simplified, central management and maintenance. Administrators control a converged infrastructure through a single management console. Training requirements are reduced, and IT has a single point of contact for support, even if the solution includes components from more than one vendor.
- Lower costs. More efficient cabling, lower power and cooling requirements, fewer maintenance contracts, higher resource utilization, and a smaller footprint with fewer moving parts make a converged infrastructure less expensive to operate.
- Faster deployments. A converged infrastructure is typically up and running in days as opposed to months. Manual configurations and errors that commonly cause delays are replaced with a fully automated, orchestrated solution.
- Less risk. Because a converged infrastructure is preconfigured and pretested for various workloads, there is a much lower risk compared to building an IT infrastructure from the ground up. Performance is much more predictable.
- Easier scalability. Provisioning equipment, applications and services is simpler and faster, and changes can be made seamlessly without disrupting the rest of the IT environment.
- Improved business agility. Because time-draining silos are eliminated and orchestration software makes it easy to add new solutions, IT can more quickly adapt to evolving business priorities and market conditions.
It’s not uncommon for organizations to take a best-of-breed approach to IT, choosing the best hardware, software and services from various vendors with the goal of creating an IT all-star team. While this approach will arm organizations with world-class players, managing those players and getting them to play nicely together is a major challenge. With a converged infrastructure, someone else has already assembled a cohesive team for you – a team that’s ready to hit the field from day one.
To determine the best path forward, you need to understand what types of changes converged infrastructure will bring to your organization – technically, operationally and culturally. How will it affect your existing IT environments? How will roles change? Will it be difficult to get your team to embrace these changes? Is your current infrastructure aligned with your business processes and goals, or is it time for a change? Sigma Solutions can help you answer these questions so you can take advantage of a more efficient, easy-to-manage IT environment.
According to a Frost & Sullivan survey of midmarket companies, keeping up with new technology is the biggest IT challenge organizations are facing today. This is an obstacle that goes beyond staying abreast of the latest innovations. Organizations of all sizes are struggling to choose and implement the kinds of IT solutions that create true competitive advantage.
That’s because many IT organizations are stuck in the old 80-20 rut. As much as 80 percent of IT resources continue to be dedicated to managing and maintaining existing and often outdated technology, while only 20 percent are spent on strategic initiatives that boost productivity and revenue. Instead of spurring growth, technology is causing many organizations to remain stagnant.
More and more organizations are adopting a managed services model, in which an IT service provider remotely manages the organization’s IT processes. Managed services include network monitoring, data backup management, server maintenance, security and patch management, tech support and other services.
A managed services provider (MSP) can help organizations optimize their IT environments. Benefits of this model include:
- More efficient operations. An MSP can help you streamline your IT processes, dramatically reduce maintenance and support costs, and remove layers of complexity in order to deliver critical services more quickly and effectively.
- Better use of in-house IT resources. Most organizations have limited IT budgets and personnel. Utilizing managed services allows these organizations to dedicate IT resources to strategic growth initiatives and outsource time-consuming, day-to-day tasks.
- Greater predictability. MSPs use automated tools that minimize human error. At the same time, best-in-class MSPs employ best practices that ensure critical maintenance is performed regularly.
- Improved network resilience. Managed services can help detect and remediate problems before they cause downtime. Sophisticated security tools are closely monitored to thwart cyber attacks, while remote backup and disaster recovery solutions can ensure access to mission-critical applications and services should disaster strike.
- Fewer compliance headaches. Industry regulations are constantly evolving and many requirements are becoming more stringent. A recent study by Six Degrees Group found that more than half of IT professionals would prefer to outsource data compliance to an MSP. An MSP can help ensure regulatory compliance by monitoring for events that could result in downtime or data loss.
- Faster implementation of new tools and services. An MSP typically has a level of expertise that few in-house IT departments can match, as well as the resources to evaluate the latest IT solutions. The MSP can serve as a “virtual CIO,” helping you to deploy new solutions quickly and ensure they’re aligned with your organization’s business processes and goals.
- Data for improved budgeting and decision-making. Based upon data gathered by remote monitoring and reporting tools, organizations can fine-tune their budgets and be prepared to ramp up or scale back services as business needs evolve.
To take full advantage of the benefits of managed services, IT should determine which tasks can be automated using remote tools. These tasks are ideal candidates for outsourcing to an MSP. Look for a provider who has extensive experience and offers a blend of managed and professional services that can be strategically combined to meet your specific business needs.

Welcome to the Era of the ‘Third Platform’ - 2014.02.20
How relevant is the desktop computer to your personal computing experience?
For many of us, the PC remains a primary computing tool even as we add more mobile devices to our arsenals. That stems in many respects from the traditional end-user computing architecture, in which client devices must be capable of running rich applications and connecting to the network for data and services. That architecture has not translated well to the mobile computing model due to the memory, processing and power limitations of the device.
The cloud changes the mobile computing paradigm by shifting data processing and storage off of the device. With the cloud you gain the ability to handle Big Data, Web 2.0 technologies and other rich applications on a mobile platform — what some experts are calling the Third Platform.
International Data Corp. analysts coined the term “Third Platform” to describe the next major era in computing, after the mainframe and PC platforms that preceded it. The Third Platform represents a symbiosis of mobile computing, cloud services, Big Data analytics and social networking, and IDC describes it as “the industry’s emerging platform for growth and innovation.”
The IEEE Computer Society refers to the trend as the “Mobile Cloud” while Gartner analysts prefer the term “Nexus of Forces.” But all seem to agree that this new model will dominate the technology landscape in the foreseeable future and drive technology investments in 2014 and beyond.
The mobile device serves as the foundation of the Third Platform as smartphones and tablets continue to displace traditional PCs and laptops. The cloud forms the next layer, with spending on cloud technologies and services expected to increase 25 percent in 2014. As these forces combine, workers are no longer anchored to the PC as their primary computing hub, and organizations are able to streamline workflows through next-generation applications and services delivered to mobile devices.
The increasingly complex needs of mobile users are expected to drive greater reliance on data center infrastructure, and IT must be prepared to support those needs. Some of the trends we are seeing:
- Social networking. Social technologies are driving not only customer engagement and marketing strategies but product and service development processes. As a result, organizations are starting to integrate social tools with business applications and incorporate the identity management systems of social networks into their user authentication processes.
- The personal cloud. Personal cloud solutions enable IT to provide seamless, secure access to business apps and data to any device, including PCs, with identity-based provisioning and policy-based control.
- Big Data. Organizations are struggling to make sense of the huge volumes of unstructured data they generate. The cloud provides the scalable infrastructure needed to transform Big Data into actionable insights that users can tap on demand.
Perhaps more than anything else, the Third Platform will shift IT’s focus from devices to services. Although devices are still needed to access applications and data, the specifics of devices will become less relevant.
What does all this mean to your business? The Third Platform is expected to become a disruptive force in almost every industry. That’s why Sigma has developed a comprehensive suite of services and solutions focused on end-user computing and the cloud. Sigma is here to help you embrace the Third Platform and develop a strategy that will help create competitive advantage in 2014 and beyond.
Integrated Infrastructure: Combine and Conquer - 2013.12.11
One of the strongest areas of growth in the IT industry is integrated infrastructure — International Data Corp (IDC) reports that integrated infrastructure sales rose 80.3 percent year over year during the second quarter of 2013. IDC defines integrated infrastructure as “pre-integrated, vendor-certified systems containing server hardware, disk storage systems, networking equipment, and basic element/systems management software.” Missing from that definition is the tremendous value these solutions bring to customers.
Traditionally, IT environments have been assembled by purchasing, sizing, configuring and integrating servers, storage and network gear. The whole process takes weeks or months, and involves multiple IT teams with expertise in the various components. As business demand for IT services has accelerated, IT organizations are finding that they are unable to keep up using this build-as-you-grow model.
Virtualization has further altered the dynamic. IT can roll out of servers and applications in a matter of days but the rest of the infrastructure often lags behind, even with automated provisioning. One IT manager put it this way: “We tried organizationally to automate these things, but if you have five different processes you still have five handoffs.”
Integrated infrastructure solutions relieve these bottlenecks by bringing together a technology stack in which all components have been configured and sized to support various workloads. What’s more, the technology stacks have been tested to ensure interoperability and certified to deliver optimal performance, giving IT the confidence to roll out new services in a hours rather than days.
Integrated infrastructure solutions are increasingly popular among organizations seeking to deploy new applications rapidly and reduce capital and operational expenses by maximizing utilization, simplifying management and minimizing downtime. A survey conducted by Zenoss conducted during the first quarter of 2013 found that 30 percent of respondents are using integrated infrastructure, and more than half are either considering or planning to adopt it.
Last year, Enterprise Strategy Group asked IT managers which infrastructure deployment model they were using and which model they would prefer to use. Nearly half (46 percent) said they were using the do-it-yourself model, buying individual components and building the environment from the ground up. However, 36 percent said that they would prefer to use an integrated infrastructure solution, compared to just 28 percent who would prefer the do-it-yourself model. If that survey were taken today, it is likely that a greater percentage of respondents would prefer integrated infrastructure solutions.
Integrated infrastructure solutions deliver key advantages:
- Faster, more efficient deployment. IT departments don’t have to devote time and resources to procure and configure of each data center component.
- Improved performance. Integrated infrastructure solutions are pretested to optimize performance and ensure the seamless sharing of intelligence between hardware components.
- Simplified management. Management is centralized, policy-driven and automated to reduce the burden on IT.
- Better service and support. The entire technology stack is certified by all vendors, who guarantee to work together to support the customer. There is no finger-pointing if something goes wrong.
- Lower total cost of ownership (TCO). All of the above-mentioned advantages help reduce capital and operational costs. Organizations have reported a full return on investment in just eight months.
These key advantages are driving the fast pace of adoption of integrated infrastructure solutions, especially among those organizations that are increasing their use of virtualized and cloud-based services. IT executives view integrated infrastructure as the foundation for next-generation data centers and a key enabler of new business initiatives.
The right partner is critical to success, helping to ease the transition, assist in the certification process and enable collaboration among the vendor, customer and deployment team. Sigma delivers a suite of services across the full lifecycle of the converged stack — consulting, implementation and operational support. Sigma has the right mix of experience, expertise and vendor relationships to help you gain maximum value from integrated infrastructure solutions.
Corporate America has reached a critical stage in the shift to digital technology. Enterprises are quickly moving to cloud-based networks, embracing mobile platforms and mining big data with an eye toward increased efficiency, flexibility, productivity and customer satisfaction.
Unfortunately, the typical enterprise is realizing just 43 percent of this technology’s business potential, according to a global survey of CIOs by Gartner, Inc.’s Executive Programs. One major obstacle is the supply of skilled IT labor, which hasn’t kept up with technological innovation and has many companies scrambling to manage, monitor and maintain their IT infrastructure.
If you don’t have people with the right IT skill sets, any competitive advantage gained by this technology is lost. To avoid falling behind and potentially crippling your business, you can utilize managed services to outsource IT operations, bring people on site with supplemental staff augmentation, or hire new employees. Each option has benefits depending upon your requirements.
The Case for Managed Services
- You can focus on your core business. IT may be critical to your company’s growth, but IT operational tasks are probably not among the core business activities that made your company successful. Managed services enable you to out-task IT operational functions so you can focus on strategy and new initiatives.
- You can control costs and operate more efficiently. With managed services, you pay a predictable monthly budget for the work performed and the results produced. You gain significant cost savings through greater productivity, increased uptime, more efficient operations and reduced personnel costs.
- You can maintain flexibility and adaptability. Managed services allow you to ramp up and scale back your IT operations as needed to meet changing business requirements.
- You can avoid the recruiting and training process — and gain 24×7 operations without staffing multiple shifts. Forget about job listings, interviews, job training or learning curves. With managed services, your outsourced IT team already has the skills needed to hit the ground running. And they’re available 24 hours a day, 365 days a year to meet mission-critical requirements.
The Case for Staff Augmentation
- You can maintain complete control of your resources. You can closely monitor everyone on site and make sure each individual is aligned with your business processes and goals.
- You can leverage new and existing resources. Staff augmentation enables you to bring new skills and knowledge to your office that can be transferred to your employees to improve their job performance and productivity.
- You can promote and enhance collaboration. Don’t underestimate the power of a close-knit team that can instantly share ideas face-to-face. This can improve morale while reducing confusion and corrections.
The Case for Working with a Solution Provider that Offers Both
Managed services may be a better fit for certain operational requirements, while staff augmentation is ideal for other types of projects. Sometimes your IT needs and solutions will overlap. Wouldn’t you rather get the best of both worlds from one company?
A solution provider that offers both managed services and staff augmentation can help you keep your IT operations and initiatives moving forward efficiently and effectively. Instead of constantly trying to fill skills gaps, you’ll be able to take full advantage of new technology to advance your business.
This is a business decision that doesn’t require analysis of tons of data. It’s just common sense.
What challenges do you face because of the IT skills gap, and what are you doing to overcome them?
How Can IT Cope with the Speed of Business Change? - 2013.05.06
Here’s a sobering statistic. Gartner analysts estimate that, through 2015, just 10 percent of IT organizations will have the operational and infrastructure agility to respond to the speed of change required by the business.
On the bright side, that represents a significant increase in IT agility over the next two years. Less than 2 percent of IT organizations are sufficiently responsive today.
Clearly, IT is not keeping pace with the business despite the growing use of virtualization, scale-out storage and other technologies that facilitate IT agility. The authors of the Gartner report explain that the problem is operational rather than technological. Pressured to ensure high availability and data integrity, IT has become risk averse and reluctant to change its processes and internal controls. Yet change it must in order to meet business demands.
Obviously, change can’t be implemented willy-nilly. Gartner recommends that IT organizations review their change management processes from both a business and IT perspective in order to better balance risk aversion against business velocity. Only then can they ensure that the right people, processes and technologies are in place.
Let’s skip the “people” component for a moment and focus on the other two. Many IT organizations continue to rely on manual or semi-automated processes that fail to capitalize on the efficiencies of today’s data center technologies. In many cases, IT also lacks the management tools needed to optimize operations — or, worse, has a growing array of management point products without an overarching operational structure or sufficient staff to watch all the little needles and dials.
With constrained budgets, skills gaps and increasingly stringent SLAs, it’s little wonder that IT is loath to abandon what has worked in the past. Few IT organizations have the resources and expertise to support current workloads and data volumes — much less effect real operational change.
This is where IT-Operations-as-a-Service can help. IT-Operations-as-a-Service goes beyond commodity managed services programs to help IT shops create an optimized operational environment. We’re not talking about ensuring a “green light” — we’re talking about an operational model that can scale rapidly to meet changing business requirements. And, oh by the way, it can deliver significant cost savings through improved efficiency and lower personnel costs.
IT-Operations-as-a-Service is able to achieve these benefits through automated processes and procedures and a secure and auditable management platform that supports proactive maintenance, task management and remote support. The service provider should deliver 24×7 support coverage, problem ownership and streamlined escalation in a flexible model that meets the customer’s SLAs and business requirements.
Of course, if process and automation were the only things necessary to optimize IT operations, many more organizations would be prepared to handle the accelerated pace of business change. The IT-Operations-as-a-Service provider should also have deep experience deploying and supporting large, heterogeneous networks and expertise spanning all IT operational functions and key enabling technologies.
In a future post we will examine how both IT-Operations-as-a-Service and supplemental staffing can fill skills gaps and how to choose the best solution for a particular function. In the meantime, we would be interested in hearing about how your IT organization is managing the pace of business change.Posted in: IT Operations
Object Storage: The Time Is Right - 2013.04.08
Virtualization has transformed the data center by breaking the relationship between applications and the IT systems on which they run. However, the benefits of virtualization often are offset by increased storage complexity and expense.
Unified storage provides a solution to this quandary by allowing organizations to consolidate and virtualize storage across protocols, environments and mixed storage platforms. Combinations of block storage (Fibre Channel or iSCSI) and file storage (NAS systems with CIFS or NFS) can be managed via a common set of features such as snapshots, thin provisioning, tiered provisioning, replication, synchronous mirroring and data migration — all from a single user interface. This shift toward a shared infrastructure enables organizations to achieve storage utilization rates of 85 percent or more, compared to the sub-50-percent rates in standalone storage silos.
Unified storage remains an evolving technology, however. Typically, these systems leverage virtualization to create deeper integration of file- and block-based storage. New to the mix is the addition of object storage.
In a file-based system, a data file is accessed by locating the specific address within the file system hierarchy. With object storage, a unique identifier plus the file’s metadata is used to locate the file. Because objects are retrieved using their unique identifiers, there’s no need to know a directory path or even the object’s location. This location transparency makes object storage ideal for managing and archiving large quantities of static information in the cloud.
In fact, object storage is geared toward the cloud — it uses the HTTP protocol rather than file or block storage standards. Applications access data using open standards such as SOAP (Simple Object Access Protocol) and REST (Representational State Transfer), which are designed to look for the unique identifiers.
Object storage is particularly well suited to unstructured data such as videos, images and sound files that don’t necessarily need hierarchical indexing. That’s why sites such as Facebook use object storage to handle massive volumes of multimedia files, and some enterprises are using it for archiving unstructured data, email and virtual machine images.
Interest in object storage is increasing due to the explosion in unstructured data growth driven by regulatory compliance requirements and data analytics. In addition to distributed access, object storage gives you the ability to store millions of objects without running up against the restrictions associated with file-based storage systems. Object storage also uses a flat address space, reducing complexity by eliminating the need to manage logical unit numbers (LUNs). And it makes sense to build a storage infrastructure based upon the public cloud model if you’re implementing a private cloud.
Object storage is not a replacement for file- and block-based storage. It is not well-suited to data that changes frequently, and the HTTP protocol limits throughput. The fixed attributes of file storage are needed to ensure consistency in shared-file applications, and the performance of block storage is required for high-performance OLTP applications.
However, organizations grappling with growing volumes of unstructured data should consider adding object storage to the mix. Sigma can help you evaluate and deploy an intelligent, object-based storage solution that helps combat storage sprawl and increase efficiency.
Three Paths to a More Agile Infrastructure - 2013.01.10
By John Flores,
VP of Marketing and Business Development
IT-as-a-Service is the new nirvana, an agile IT infrastructure that enables rapid response to changing business conditions and needs. Some people refer to this agile infrastructure as the private cloud. Whatever you want to call it, it represents a transformation of the traditional data center architecture.
Traditionally, IT infrastructure was built vertically to support individual applications. That monolithic structure made it difficult to scale the environment to meet increased storage or performance demands. The new agile IT infrastructure is built out horizontally, with applications spread across pools of virtualized compute, storage and networking resources. Because those pools can readily scale in response to changing requirements, this new architecture is much more flexible and efficient.
There are three ways to go about building an agile environment. One option is to go out and buy best-of-breed components and construct it from the ground up. The beauty of that strategy is that it’s extremely flexible and can be finely tuned to existing infrastructure and specific business requirements. The downside is that there is a good deal of complexity and effort involved. That’s why customers call Sigma — we have proven experience helping customers build private clouds.
At the other end of the spectrum is a converged infrastructure solution such as Vblock from VCE. Vblocks are validated “stacks” that integrate best-in-class virtualization, networking, compute, storage, security and management technologies. They offer a more streamlined approach to creating private clouds, and Sigma has the certifications and expertise to successfully integrate Vblocks into the IT environment. But while Vblocks deliver pervasive virtualization and scale, a pre-engineered, pre-integrated solution may be somewhat limiting in certain environments.
A third option is to use a reference architecture — a tested and validated design based upon best-of-breed technologies. NetApp’s FlexPod solution, for example, is a predesigned base configuration comprising the Cisco Unified Computing System (UCS), Cisco Nexus data center switches and NetApp FAS storage. The reference architecture is modular or “pod-like,” such that the configuration of each customer’s FlexPod may vary. Nevertheless, a FlexPod unit can easily be scaled up by adding resources or scaled out by adding FlexPods. It creates an agile computing environment that can meet ever-increasing performance demands and support “big data” workloads.
A Sigma customer recently experienced the benefits of the FlexPod approach. The customer had already implemented NetApp storage, Cisco UCS and a Nexus fabric, and opted to leverage that infrastructure to create a FlexPod. Sigma engineers helped the customer tune the configuration in order to validate the design. It enabled the customer to rapidly expand a virtual desktop initiative with the confidence that the infrastructure could support the workload.
EMC’s VSPEX is another reference architecture. With VSPEX, customers can combine their choice of industry-leading compute, networking and virtualization technologies in a proven infrastructure validated by EMC and built on highly flexible EMC storage and backup infrastructure. As a result, VSPEX Proven Infrastructures significantly reduce the planning, sizing and configuration burdens associated with private cloud deployments.
Of course, Sigma has been providing these types of solutions for a number of years now. Sigma’s broad and deep experience across the data center enables us to create robust yet highly flexible environments based upon best-of-breed technologies. Whatever solution best meets the customer’s needs, Sigma has the knowledge and experience to transform the IT infrastructure and achieve the nirvana of the IT-as-a-Service model.
End-User Computing Now, Part 2 - 2012.11.05
By Elias Khnaser
CTO, Sigma Solutions
In part one, I offered a high-level overview of a suggested end-user computing strategy. Let’s break down the topics, starting with the desktop strategy.
While we may be in the post-PC era, it doesn’t mean that physical desktops and laptops are going to disappear. We need to continue to fine-tune and deploy desktop management tools like Microsoft SCCM and others. On the other hand, ignoring desktop virtualization and VDI is also not acceptable anymore and continuing the rhetoric and debate about CAPEX vs. OPEX costs and the exaggerated costs of VDI is just a bunch of “malarkey” (sorry, I had to find a use for this word).
A well-planned and designed desktop virtualization infrastructure can be very cost-effective and cheaper than a physical implementation. It is also about time to position the benefits of desktop virtualization from a business perspective, BC/DR, flexibility and more. We must look beyond how much is it going to cost and consider what we gain. Anyone can lie with numbers and you can make them look the way you want, so let’s agree to just get past the TCO of desktop virtualization — it has a place and it is an integral part of the strategy.
Mobile Device Management, Mobile Application Management and Mobile Information Management — they’re all new terms, all colorful terms. And so, with the mobile device explosion we need to evolve our mindset from one that has traditionally always been about controlling the device to one that governs the device. Better yet, we should govern enterprise resources on these devices. MDM will aid in enforcing device passwords, remote selective wipe of the enterprise resources on the device, encryption, reporting, etc.
MAM is about mobile applications, sandboxing and encapsulating mobile applications so that we can apply policies against them. Without sandbox or application wrapping, it will be very difficult for enterprises to control what applications can and cannot do. This is especially apparent with native e-mail clients. Without sandboxing the e-mail client, mobile applications that get installed on the device could gain access to corporate contacts and information that otherwise would not be allowed. Native e-mail clients are also so embedded into the mobile OS that it is difficult to sandbox them. That’s why organizations such as Citrix, VMware and others now provide their own version of a sandboxed e-mail as a complimentary alternative.
MAM can also serve as a consolidated application store for the enterprise where Windows, SaaS, mobile and other applications can be consumed. This is, again, a technology where there might be overlap between MDM vendors and enterprises such as Citrix and VMware. As you are making your technology selection, choose a MAM solution that could integrate best with your desktop strategy and technology partner selection.
Mobile Information Management, also known as Mobile Data Management, provides essentially a Dropbox-like functionality for the enterprise. The idea here is to enforce policy-driven security that would allow or deny file syncing to certain devices in certain locations. More granularly, it would allow or disallow certain file types on certain devices, etc.
Social Enterprise / Collaboration
Do you really enjoy sending one-word e-mails, e-mails that say “Thank you” or “Yes”? Do you enjoy searching through thousands of e-mails to locate the conversation you were having, or to find a file attachment? If you are like me, you probably despise e-mail — I truly hate e-mail and in my consulting world, when working on a customer’s statement of work, we start versioning the SOW and send it back and forth. There has got to be an easier way. What if we had a Facebook-like enterprise where we can collaborate with colleagues? Better yet, what if this social enterprise can be linked to our MIM solution so that we can drag files and collaborate on them while they are in a centralized, secure location?
Of course social platforms still need to mature somewhat for the enterprise and you have to be able to answer questions such as:
- What level of use of social networking will you allow?
- Are any social networking services more enterprise-friendly than others?
- How are they used for work purposes? (crucial question)
- How do you see social enterprise changing communication and collaboration behavior at your company?
I will take one step further and say that I believe social enterprise platforms such as SocialCast and Podio and others have the potential to become the next desktop and I have blogged about them here several times.
Every customer tells me they have a wireless infrastructure and while I recognize that a wireless infrastructure is part of the DNA of every enterprise, for the most part, what many dismiss or disregard is that these wireless infrastructures were not built to handle the number of devices that are or will be connecting connecting to the infrastructure. More important, however, are the types of services delivered over these wireless infrastructures that are significantly different.
Remember, in an end-user computing strategy, you have to take into account remoting protocols like PCoIP, HDX, RDP and others. You also have to take into account the new and updated technologies that could make other services better. So, please don’t ignore the wireless infrastructure.
We are also looking for a secure and scalable infrastructure with pervasive coverage to detect and mitigate sources of interference. A wireless infrastructure capable of location tracking will tie very nicely with your MDM tools to enable or disable certain functionality depending on your geographic location.
There is no way you are thinking about an end-user computing strategy and BYOD in particular without taking into account security generally and network access control in particular. You should be investigating and planning to control wired and wireless access and dynamic differentiated access policies, enforcing context-based security, and providing self-service access and guest lifecycle management via agent or agentless approaches.
Now it’s your turn. Do you agree that an end-user computing strategy is needed? And if so, how we can refine and fine-tune the strategy I laid out here? Comment away!
Not Just VDI — It’s All About End-User Computing Now - 2012.10.30
by Elias Khnaser
CTO, Sigma Solutions
End-user computing has expanded so much and gotten even more complex. In this two-part series, we will explore the strategies that could be used in enterprises to address all the current issues: from consumerization and BYOD, to desktop virtualization and physical desktop management.
It used to be fairly simple and straightforward: End-users either got a desktop or a laptop and those who needed a bit more accessibility got a Blackberry for mobile email, and that was it. Sophisticated enterprises managed those desktops with Microsoft SCCM, Symantec Altiris, LANdesk or similar technologies.
Those days are gone and the situation has radically changed, with the needs and requirements of end-users having evolved to the point that they have, on average, two or three devices — a PC and smartphone and/or tablet.
Access to resources has also changed. We used to just load everything on the laptop, but now end-users want and need selective access to resources on their preferred device from anywhere at any time over any connection.
That means it’s time to rethink the end-user computing strategy.
For many years, IT treated the end-user space as a second-class citizen, with no real IT talent devoted to it or any serious planning or strategy. The attitude was to just get it done no matter how sloppy the method. Most of our time and effort was focused on the data center, the crown jewel of every IT engineer’s resume. We wanted to go through the ranks, through the help desk and get to the data center — where real computing happens.
Well, today, enterprises are demanding that the same level of seriousness we dedicated to the data center now gets focused on the end-user computing side.
Where do we start? Let’s begin by identifying the components of this new strategy:
- Desktop Strategy — this means a strategy for physical and virtual desktops and applications
- MDM/MAM/MIM — necessary to govern the mobile devices, applications and data
- Collaboration — a modern way of collaborating between end-users that goes beyond the traditional tools to reach the social enterprise
- Wireless Infrastructure — a robust, dynamic and scalable wireless infrastructure to support the influx of devices and services
- Security — at the heart of any strategy is security, and end-user computing security in the age of BYOD is crucial
Now, the challenge is the ability to weave all these technologies together and avoid overlap, as some of the vendors in question provide similar capabilities. For instance, most MDM vendors now have some sort of Dropbox-like functionality, but so do desktop virtualization vendors such as VMware and Citrix.
Next time, we’ll break down these components and discuss the strategy in more details. In the meantime, please share with me in the comments section your feedback, especially if I have missed any high-level topics.
Network Evolution and SDN/OpenStack: My Four Cents - 2012.10.26
By Brad Moss
Senior Consulting Engineer
Companies such as Vyatta have been delivering software-defined networking (SDN) for years. It works great! The issues will come with performance hits depending on the technologies being deployed in software.
A prime example is VPN. Any VPN solution worth the name of Concentrator has hardware chips that are purpose-built to process the encryption and decryption faster than any CPU can handle (assuming the CPU is multitasking with other threads from servers and whatnot). The real issue is connecting disparate systems together — which still requires physical cabling and will cause network hardware to be around for a long time.
NXOS is VM running on a Nexus chassis and likewise with the 62xx fabric interconnects. They actually run three VMs: management, Web GUI cluster and the actual FI software. So I’m not sure it fits to say that the network vendors are not moving to SDN. They just have not approved off-the-shelf hardware to run it.
In the case of ideas such as OpenFlow, a capitalistic society will not allow a completely open source product to take over the masses. Very few open source items ever make it into the mainstream. As long as people need innovation and increased computing requirements from the CPU, memory and latency between physical servers, there will have to be higher-grade silicon in the hardware rather than RadioShack “build it yourself network hardware” to forward that information.
He who owns IP is king. Even if we find a way to make the protocol widespread there will be something for sale to support it (Red Hat).
Yeah, I think networking is overly complicated in some areas and could be simplified to the point one could sit down and manage the entire infrastructure via a central console in a single pane of glass. UCS is a prime example. Now server setup takes three to five days. Once installed and configured, hundreds of servers can be rolled out at the click of a mouse in an easy-to-use front end. I can see networking happen the same way. Oh, and as with SIP, every vendor will have their own flavor of the “standard” that will not work with others kindly.
So in the end IBM virtualized everything in the 1960s/70s then along came the new marketing team: “We need to get computing resources at the users’ hands and ‘decentralize.’” It is all about marketing and selling product. The era we are in now is to get personal computer closer to the data sources and get the user ultra-portable, high powered devices to run their personal computer remotely. So now everyone is winning in this deal except for the PC manufacturers. Guess they are the odd man out.
I have researched SDN and OpenStack a bit more since writing the first half of this post. It makes a lot of sense and takes an out-of-the-box look at networking. Network engineers are the masters of complexity (http://youtu.be/CW7lT6oUWjI). That is too true. For some this is a problem just as VoIP was for the old telecom guys. The stagnant network guy that has been in the same job for 15 to 20 years and knows every little piece of hardware in his network (master of complexity) is going to be slow to adopt the SDN architectures.
Once networks are simplified and are essentially controller-based similar to how wireless networks have been operating for the last few years, those complexities go away. If the network guys do not adopt a new technology they will be out of a job.
I have been working in data center and enterprise-class networks for 13+ years. It is my goal in every situation to make what I am doing today irrelevant in the future. This requires us to continue learning and adapt to the new trends and not go stale or push back on the technology.
Interesting times are upon us in the network area. This is really the first time there has been a real effort to change network since Ethernet and IPv4 went mainstream. IPv6 was ratified in 1998 and the government missed their timeframe in the last month or so to get on the “new” addresses scheme. I have to give a shout out to all the people around me who see my potential and urge me to move into new areas. That’s how I became a UCS deployment engineer. Not just because it is a Cisco product.
Big Data, Big Storage Problems - 2012.10.22
By John Flores,
VP of Marketing and Business Development
“Big data” is the one of the biggest buzzwords in the IT industry today, a term used to describe the massive amount of structured and unstructured data produced by a new generation of systems and applications. Organizations are seeking to tap this data to uncover new insight and make more-informed business decisions. In many cases, however, organizations are finding that they have to resolve big storage problems before they can even begin to consider the potential for big data.
We’re talking about datasets so large that they transcend the ability of typical database software tools to capture, store, manage and analyze. Although the definition is necessarily subjective, most analysts use the term in reference to petabytes, exabytes or potentially even zettabytes of data.
This clearly puts a strain on data storage infrastructures. The traditional “scale-up” storage architecture suggests that the sky is the limit. In reality, however, the overall volume of data has become so high that it exceeds the capacity of traditional storage systems. In order to accommodate big data storage volumes, organizations end up deploying tens or even hundreds of storage silos, most of which are underutilized. This storage sprawl increases capital outlays and power and cooling costs, and causes severe management headaches.
Performance bottlenecks are another problem. Traditional storage systems just don’t have enough horsepower to complete big data operations efficiently. In order to handle all the I/O requests, organizations tend to add more spindles to the environment and reduce the amount of data stored on each disk. This again leads to a bloated yet underutilized storage infrastructure.
Big data demands a rethinking of the storage infrastructure. One solution that’s gaining traction is EMC Isilon scale-out storage. An Isilon IQ system consists of industry-standard hardware components that function as nodes connected via an Infiniband high-speed interconnect. OneFS, a next-generation storage operating system, serves as the intelligence behind the Isilon IQ storage platform. Increasing capacity, performance and throughput is as simple as adding more nodes to the cluster — OneFS automatically redistributes data evenly across all nodes. The result is a single file system that can scale out on demand, enabling one person to manage one petabyte as easily as 100 terabytes.
A new breed of scale-up storage solutions can provide the processing power to conquer performance bottlenecks. EMC VMAX and Hitachi Data Systems VSP are high-performance solutions that deliver the raw horsepower needed to handle large datasets.
These solutions can be used in concert to create a robust storage environment capable of handling big data. De-duplication, tiering, archival and retention policies can also be used to streamline the big data environment.
Of course, what’s “big data” today will rapidly become the norm as data volumes continue to skyrocket. Traditional storage subsystems will no longer be viable options. Organizations need to start preparing for that inevitable future with a new approach to storage.

VP of Operations and CIO
Almost every CIO who responded to Gartner’s 2012 CIO Agenda survey late last year said that reducing operational costs and increasing IT investments were top priorities. However, many organizations struggle to contain IT operational costs, creating a vicious cycle that precludes needed investments. Gartner Research Vice President Stewart Buchanan explained it this way:
Organizations that overspend on operational activity have little money left to invest in new projects. Without reinvestment, organizations cannot restructure and optimize their operational spending. This results in rising non-discretionary costs, which in turn result in further underinvestment, lack of competitiveness, failing client service and loss of revenue. This makes future spending even less affordable and even less avoidable.
Part of the problem stems from a failure to include operational expenditures in project budgets or to be overly optimistic in operational cost estimates. But at a more fundamental level, many IT shops find it difficult to manage today’s complex environment — much less prepare to meet tomorrow’s operational needs.
Staffing is an ongoing challenge. It’s tough to find skilled and certified personnel with the right cultural fit, and then keep them up-to-date with ongoing training. IT managers often find themselves running a 24×7 operation with a 9×5 staff. Worse, operational knowledge typically is held by a few key personnel, putting the organization at risk. And because of personnel constraints, many IT shops lack mature processes for change control, capacity planning and problem management.
Management tools have largely failed to deliver promised efficiencies. Most monitoring systems spit out raw data with little actionable information. More sophisticated tools are overly complex and often wind up as shelfware. As a result, organizations lack visibility into IT performance and insight as to the true costs of IT operations.
Fixing IT operations requires the right blend of people, process and technology, but all too often organizations look at these components discretely. Adding contractors just brings in more bodies without driving real change. Outsourcing firms may take a process-driven approach, but generally lack the flexibility needed to support a changing environment. Management tools can enable more proactive operations when implemented correctly but they increase the IT footprint and total cost of ownership. How many IT managers have lamented that they spend more time mapping support tools than the actual technology?
Sigma has developed an IT-Operations-as-a-Service that addresses all aspects of the operational environment. We looked at the market and captured the best of the IT outsourcing model — great technical expertise and refined processes — and combined those resources with the technology needed to manage complex environments. We built a relationship-oriented solution from the ground up, with local talent, 24×7 coverage, a cloud-based operations platform and well-defined standard operating procedures, all in a flexible consumption model in which you pay for what you use.
Almost everyone agrees that IT operations are broken in many organizations. Sigma has gone to market with an IT-Operations-as-a-Service solution designed to fix the problem once and for all. By selectively out-tasking IT operations to Sigma, organizations can begin to achieve their goals of reducing operational costs and increasing IT investments.Posted in: IT Operations
Optimizing IT Operations - 2012.09.04
By Brian Nettles,
VP of Operations and CIO
Some interesting buzz came out of VMworld last week. In his keynote address, incoming VMware CEO Pat Gelsinger called today’s data center “a museum.” His point was that data center operations haven’t kept pace with the rate of change in today’s IT environment.
Some of that has to do with technology but a lot of it involves process. Too many IT shops have too many manual processes that can’t keep up with the speed, flexibility and scale of today’s data center. Organizations are rolling out new IT services faster than ever but don’t have the resources to manage and support them properly. There needs to be greater emphasis on efficiency, automation and best practices.
There can be a tendency to put a Band-Aid on the problem and hope it gets better on its own. If we bring in a couple of contractors or resident engineers we’ll get through this crunch, the thinking goes. But adding contractors to supplement in-house resources is not cost-effective for day-to-day operations and does not address systemic problems within the IT organization. IT needs to rethink the data center operating model for the cloud era. And that’s tough to do when you’re already stretched thin and on a tight budget.
The fact is, the entire IT consumption model is shifting. Knowing why, how and when to consume a given product or service is half the battle. Using a combination of Remote Infrastructure Management (RIM), field services and support, and contractors can help. This hybrid, IT-Operations-as-a-Service model allows for a more cost-effective, SLA-based and business-oriented approach, enabling you to systematically out-task IT maintenance and management functions so your IT team can focus on strategic initiatives.
Tailoring your service consumption will help you begin to transform your IT operations. A true enterprise-class IT-Operations-as-a-Service solution will feature the right skill sets on demand, remote or on-premise management, automated tools and standardized methodologies that enable scalability, rapid problem resolution and repeatable results. The right level of solution will bring together people, processes and technology. And through efficiency and economies of scale, IT-Operations-as-a-Service can dramatically reduce your operational costs, leaving more of your budget for innovation.
I’m not talking about outsourcing your IT operations. All too often, outsourcing simply transfers existing processes to a third party in a “people-based” model. With traditional outsourcing, IT loses control without really solving the problem. That’s why traditional outsourcing arrangements are unpopular and typically fail to achieve their objectives.
Nor am I referring to traditional break/fix support agreements. Those types of agreements are important to have when things go wrong, but they simply react to IT problems without providing predictability or scalability.
An IT-Operations-as-a-Service solution is not about system maintenance, it’s about redefining the IT operational environment and cost structure. It enables organizations to selectively outsource activities with which they don’t have capacity, competence or cost advantages. In utilizing IT-Operations-as-a-Service, the in-house IT team remains in control of the organization’s business and technology objectives while optimizing IT operations.
Where Yammer Fits in Microsoft’s Cloud - 2012.06.27
I can’t seem to stop writing about Microsoft, and as I have been touting for a while now, the company is in high innovation mode, striking on multiple fronts and it seems to be in a hurry, acquiring where it needs to, improving where it needs to and building where it must.
Just last week I was discussing whether or not the company would build or buy a tablet and Microsoft unveils Surface. I still think they will acquire RIM or Nokia. The latter is what I am leaning towards as its current stock price is ideal, but we will see.
On the heels of Windows Server 2012, all the new features of Hyper-V 3, new SQL server, new App-V 5, an enhanced cloud strategy with Azure now also focusing on IaaS instead of just PaaS, Microsoft finally admits that SharePoint and its social capabilities are not good enough for the enterprise and recognizes that this is an area where it desperately needs improving and developing something from the ground up would take time, so Yammer was acquired without hesitation.
Where will it fit? Everywhere! For starters Yammer will layer on top of SharePoint and extend its features for more social enterprise friendliness. After that, they will go after Skydrive for the enterprise and extend collaboration features to files — in the words of fellow analyst Jason Maynard, “Files are to collaboration what photos are to Facebook” and honestly I could not have summarized better.
Microsoft has recognized that both e-mail and file sharing a la SharePoint are not good enough anymore for today’s enterprises. Yammer will bring that much-needed collaboration and breathe life into Microsoft’s products, including Office.
But what else can Microsoft do with Yammer? Well, how about integration with Lync? That would be a perfect combination. Not only can you collaborate on files in Skydrive and SharePoint, but you can also launch meetings using Lync from within Yammer. It’s very similar to how Citrix will integrate Podio with the GoTo family and very similar to how Cisco will integrate WebEx with Quad.
Microsoft’s move reinforces a notion I have been circulating that collaboration platforms are likely to be the next desktop, where aggregation of resources and applications happens and where collaboration is native. I think Yammer was absolutely an inevitable step for Microsoft and I applaud the acquisition. I also think we are not done seeing consolidation — Salesforce.com and possibly SAP, IBM and Oracle are due for similar social acquisitions as well.
The Yammer acquisition clearly validates that the enterprise is ready for social business and that desktop virtualization, collaboration, cloud data are slowly converging and crossing paths to where they are a true end-to-end enterprise consumerization strategy.
What are your thoughts on the Yammer acquisition? Is your organization ready for the social enterprise?

Nutanix: Go Big or Go Home! - 2012.06.13
Is it arrogant for a company the size of Nutanix to take on the giants of our industry by saying FU-SAN? It is most definitely arrogant, but I most certainly like that because that arrogance hides a solid technical solution and an innovative perspective, a new way of thinking that essentially says that “monolithic” infrastructures are great but they are not the only game in town.
If we look at all the large cloud deployments, the likes of Google, Facebook and others we will quickly notice that they use commodity hardware in a grid computing type approach. That is not to say that they don’t have shared storage or SAN, but they have much more of these nodes that together form their compute fabric, except these nodes would need a layer, a file system that connects them together to yield the desired results.
Nutanix brings that type of thought process, that type of technology to the enterprise by offering a converged compute and storage cluster that is glued together by the Nutanix Distributed File System and it is this distributed file system that allows the Nutanix cluster to offer enterprise features that traditionally required shared storage like HA, DRS or vMotion (live migration, XenMotion). Nutanix is a 2U block or container which holds four nodes (hosts, servers). Each node can take up to 192GB RAM, dual socket Intel CPUs and three tiers of storage, 320GB Fusion-io flash, 300GB SATA SSD and 5TB of SATA spinning disk.
While Nutanix can be used for different types of use cases and workloads, I am particularly interested in it for desktop virtualization. One of the main barriers for desktop virtualization adoption has been cost and then, to an equal extent, complexity. Nutanix breaks down both barriers, as the cost of entry is very acceptable and the complexity is simplified.
A while back I had written an article on the cost of desktop virtualization versus physical desktops and a reader asked me how that would work for smaller organizations. Honestly at the time it was not going to be as effective as the value proposition I showed at scale. With Nutanix, however, we now have a story for the small organization as well as the large enterprise.
Now I have maintained for a while now that local disk is not the way to go for desktop virtualization and I have religiously argued against it because all of the suggested solutions that promoted local disk were suggesting that we don’t need enterprise features. My take on this is that is not acceptable. I don’t want to go backwards. I don’t want to lose features and I am not willing to compromise. I also had a lot of reservations on the configurations that were being suggested and we will get to that in a minute.
So why do I like Nutanix so much? There is nothing special with the hardware configuration: SuperMicro computers, Intel inside, Fusio-io cards, some SSD drives and some SATA drives… Big deal, right? I can put that together easily. Well, sure you can but that is where my reservations come into play. First, in that scenario we lose all enterprise features. Second, there are technical challenges with SSDs from write coalescing, to write endurance, etc., challenges you cannot overcome by putting hardware together. You need a software layer that addresses all these issues, and that’s where Nutanix Distributed File System comes into play. It enables the enterprise features, but also addresses some of the challenges I mentioned. So, do I accept local disk in this configuration? Absolutely.
For many customers, another challenge is they want to start small with VDI and grow into it. Monolithic infrastructures get cheaper at scale, which is why customers had to buy the infrastructure ahead of time to fit within certain discount ranges. With Nutanix you have to buy the first fully populated block with four nodes, but then after that you can buy a block with a single node in it and scale as you need to. Pretty elegant, if you ask me.
Couple Nutanix with Citrix VDI-in-a-box or VMware View Enterprise for small or medium size organizations and that is a killer solution. Couple it with XenDesktop or View Premier and — voila! — scale-out enterprise solution. The cost of desktop virtualization drops again. Next argument, please!
Now I can’t write this glowing column in support of Nutanix without finding something I don’t like. Today, the only hypervisor supported is VMware ESXi, and while I realize the market share is in VMware’s favor, ignoring Microsoft Hyper-V is a huge mistake. Since one of the use cases for this solution is desktop virtualization, ignoring XenServer is also not a great idea given Citrix’s position in the desktop virtualization market. Having said that, I do recognize that many enterprises deploy Citrix technologies on vSphere, but nonetheless, vSphere, Hyper-V, XenServer are an absolute must and I know that Nutanix is working on extending support to these hypervisors.
Another feature that would be welcome is Nutanix array- or block-based replication — maybe an OEM partnership with Veeam?
I am extremely interested in your opinion of Nutanix. I have several customers deploying and I welcome your feedback.

9 Reasons Microsoft Hyper-V 3 Is Enterprise-Class - 2012.06.04
A few years ago, I wrote a controversial column listing nine reasons Hyper-V was not enterprise ready and suggesting that Microsoft had lost its innovative edge. I think the only Microsoft employee who didn’tsend hate mail was Bill Gates, and I still maintain that column cost me an MVP award.
While I stand by my previous assessment, I also maintain that the situation has changed significantly. Over the past two years, Microsoft has gone strongly into innovation mode, not only on Hyper-V but on many other product lines. The turnaround started with Exchange 2010 and its leveraging of local storage as opposed to complete reliance on expensive shared storage and extends from System Center 2012 (probably my favorite) to the new version of SQL Server, which is following in Exchange 2010′s footsteps and technology, to the new, long-awaited and overdue version of App-V, a technology Microsoft acquired many moons ago but on which it bestowed very little development effort.
But back to Hyper-V. The new version not only addresses all of my previous beefs with the product, it goes from a position of just playing catch-up with the market leader to actually giving VMware a run for its money at the feature level. This is the first release where Microsoft is putting forth a feature that VMware does not have: the ability to do live migrations of storage virtual machines.
Let’s take a look at that and eight more features that earn Hyper-V a serious look.
1. Storage Live Migration:This capability is now built into Hyper-V Manager as opposed to requiring System Center Virtual Machine Manager, as was the case with the Quick Storage Migration. Storage live migration allows IT to migrate a VM, without any downtime, from one storage system to another. Remember that innovation I was talking about? Well, traditionally with storage live migration technologies from Microsoft, VMware and others, a shared storage repository is required for this feature to work properly. In Hyper-V 3, that is not the case. While you could use shared storage, of course–and I highly recommend doing so–you can migrate a live storage VM from local disk to local disk without any downtime. Now the ball is in VMware’s court to match that functionality.
2. Concurrent Live Migrations: I have for many years criticized Hyper-V’s lack of concurrent live migrations, and I’m very happy to report that the new version finally supports this capability. For a virtualization administrator, this is invaluable functionality. We live in fast times, and we need to be able to react at the speed of the business. Quickly moving all the VMs running on a given server is a definite requirement in any virtual infrastructure, and this release delivers that.
3. Dynamic Memory:While not a new feature in Hyper-V 3 (it was available as of Hyper-V R2 SP1), it’s worth noting in a list of reasons Hyper-V 3 is ready for enterprise use. In a nutshell, dynamic memory is a memory management enhancement that allows IT to automate adding or removing memory from a VM on the fly–very helpful when trying to improve the density of VMs on a host, for example. And it’s a vital feature in any enterprise virtual infrastructure.
4. Continuous Availability:This is actually a collection of technologies in Hyper-V 3 that includes, in addition to Live Migration and Storage Live Migration, NIC Teaming and Guest Failover Clustering.
– Failover Clustering: Today, the cluster supports only 16 nodes; in Hyper-V 3, the cluster will be able to support 64 nodes and as many as 4,000 VMs.
– NIC Teaming: IT can now combine NICs from different vendors, say, Intel and Broadcom. We also have three modes for configuring NIC Teaming: switch independent, static teaming and Link Aggregation Control Protocol; LACP is huge as it extends support for demanding applications like Citrix Provisioning Services.
Finally, for Windows Server 8 or Server 2012, depending on what the name ends up being, Hyper-V 3 has a really cool feature that leverages SMB 2.2 (I am super-excited about SMB 2.2). It can leverage file shares as storage destinations. I’m sure you’re thinking “single point of failure,” but remember, you can build up to four-node active-active clustered file servers, which provide simultaneous access to file shares. Yeah, SMB 2.2 is cool; the locking mechanism is great as well–watch out, NFS.
5. Network Virtualization:Microsoft is all-in on cloud, and in order to be effective in the cloud era, you need the network stack in your virtual infrastructure to be solid. It’s worth mentioning here that Cisco supports Hyper-V on the Nexus 1000V, so the ecosystem is also coming together. In addition, Hyper-V 3 will support policy-based, software-controlled network virtualization; this is crucial in the cloud era because everything will be about policy-driven automation and orchestration, all key enablers of infrastructure-as-a-service deployments. As part of the Hyper-V 3 network virtualization capabilities, you can also create a bridge between your on-premises and cloud deployments that enables you to move your subnets into the cloud and create logic to allow them to communicate, essentially creating a hybrid cloud.
6. Storage Enhancements:No enterprise virtual infrastructure is complete without tight integration with storage, and Hyper-V 3 introduces some impressive improvements here as well. First, the new Offloaded Data Transfer is similar in functionality to VMware vSphere APIs for Array Integration, and I’m very eager to see how that improves or even solves the locking issues with CSV, which still redirects I/O through the parent partition. Virtual machines can now support up to four vHBAs with direct access to SAN LUNs using multipath I/O. You also have built-in replication, hardware snapshotting and, my personal favorite, Remote Direct Memory Access networks for SMB storage
7. Platform Enhancements:The platform has seen some major improvements as well, with support for 320 logical processors and up to 4 TB of memory per host. It’s now possible to provision virtual machines with up to 64 vCPUs and 1 TB of memory, a huge upgrade from four vCPUs and 8 GB of memory. The new VHDX file format supports up to a 16-TB virtual hard drive. These enhancements will fuel the virtualization of Tier 1 applications and are critical for an enterprise-class virtualization platform.
8. RemoteFX:This, again, is not a new feature of Hyper-V 3, but it’s very relevant to enterprise IT. Hyper-V supports GPU virtualization, which in desktop virtualization applications can be of great benefit in terms of enhancing the user experience. Essentially, you’re able to expose a virtual graphics device to a virtual machine and allow multiple virtual desktops to share a single GPU. This would enable users to run graphically intensive applications on a VM.
9. Hyper-V Replica:Hyper-V Replica is a new feature of Hyper-V 3 and is somewhat comparable to VMware vSphere Fault Tolerance. Hyper-V Replica will asynchronously replicate virtual machines from one Hyper-V host to another over an IP network. The process is configured at the VM level, so it’s not an all-or-nothing proposition. The technology tracks write operations on the source machine and replicates them to the destination VM so that both VMs are in constant lockstep. If one VM fails, the replica takes its place without missing a ping–a pretty cool enterprise-class feature.
I am really excited about Hyper-V 3, and I hope Microsoft continues its innovation trend and directs more attention toward alternatives for the parent partition approach and to building a better clustered file system. CSV is not bad, but I think the natural evolution is a really solid, scalable file system. Hyper-V 3 will be the first real challenger to VMware vSphere 5, so let’s see how VMware responds. I think competition in this space will continue to drive innovation, and the customer will definitely be the ultimate winner.

PC Applications in The Post-PC Era - 2011.10.06
I subscribe to the school of thought that we’re already in the post-PC era, simply based on the number of mobile devices we support. That point may be arguable, but one thing is not up for debate: PC-based applications, specifically those that run on Windows, are going to be around for a very, very long time, especially in large enterprises. Yes, we hear a lot about SaaS and Web-based alternatives, but who among us doesn’t have some legacy software that we have to keep running?
Most IT teams have struggled to marry new devices, mostly tablets and smartphones with small displays and touch-screen keyboards, with Windows operating systems and the applications that love them. The main sticking point is that Windows is a point-and-click interface. Some smartphones, such as the Motorola Atrix, allow users to dock a phone in a laptop shell, thereby giving access to a full laptop screen and keyboard. Celio offers a Redfly mobile shell and dock. That is, however, another piece of equipment users have to carry. Newer phones also have some sort of video output, like HDMI, that would allow the projection of the phone’s screen onto a larger display, provided such a display is available.
The form-factor problem is another issue. I don’t believe anyone enjoys working on a Windows desktop from a smartphone screen, so people will still carry multiple devices when they move around — a smartphone, a tablet for meetings or on a plane, maybe a laptop PC or Mac just in case.
This problem isn’t going to go away anytime soon, especially because vendors like Citrix and Microsoft are releasing software that works or will soon work on any device, from Android to iOS and Windows Mobile Phone, all the way to BlackBerry and HTML5; users will be able to connect to PC-era applications leveraging VDI and other technologies. Your users may like seeing a Windows desktop or application on their favorite mobile devices, but this is just perpetuating the problem.
In response, many enterprises that have deployed desktop virtualization offer Bluetooth keyboards and mice for their tablet users to maximize the experience, but is that really the solution? There has to be a better way of addressing a PC-era computing architecture with the post-PC-era mobility frenzy.
We expect more vendors to start playing in this space, and we’d like to offer a suggestion: Figure out a way to zoom and project the keyboard and screen onto a larger surface, like a holographic display, that can be resized and that allows users to control the brightness and contrast. The technology exists. Now all of a sudden, that smartphone and VDI just became the ultimate computing device for PC-era and post-PC-era applications. We can use the full-size keyboard and holographic display when using point-and-click applications like Word or PowerPoint. The phone is always connected with Wi-Fi and 4G connectivity, so all social media and SaaS applications are available. What else would a road warrior need?
VDI has solved the problem of running Windows apps on smartphones. Now we just need those few missing pieces. We’ll be watching to see what innovations arise.
As written by Sigma’s Technology Officer, Elias Khnaser, for Information Week
One of the biggest hurdles for desktop virtualization adoption is price. Through all my interactions with customers, I am always hearing: “I heard it was more expensive, I heard there are no cost savings,” etc. So, let’s compare a desktop virtualization rollout versus a traditional physical desktop rollout and see if it truly is more expensive.
That being said, keep in mind that from a CapEx expenditure stand point, you will not see much savings. But you will see significant OpEx savings. Usually when I say this, customers will say, “My CFO does not care about OpEx, we can quantify OpEx, we can’t touch it.” I say, have a little more faith. I will accept that argument and respond to you as follows: While it is not easy for every organization to quantify or justify OpEx, the next time your manager needs a project completed in a week and you have no cycles or your current employees have no cycle, the only option is to hire more help or use consultants.
The next time your CFO’s laptop breaks down and it takes two days (being generous) to replace it and bring him back to productivity, the next time your CFO or CIO flames you for not providing adequate technical support or timely technical support to the user community which is generating money for the business, at that point you can reply to them by saying, “We have no cycles, we have been supporting our dispersed and remote user community for years using dated methods; we need a change.” At that point, the OpEx will all of a sudden look very lucrative.
Let’s proceed with the following scenario: Gordon Gekko Enterprises has 1,000 physical desktops that are 7 years old running Windows XP and are up against a hardware cycle refresh and an operating system upgrade to Windows 7. Let’s also assume the company has done its homework and knows the benefits of desktop virtualization. The company is interested in a ball park price comparison between physical and virtualized desktops. To accomplish this, I am choosing the VDI type of virtualizing desktops. While there are other types that can be used to lower the cost, I’m going to assume worst-case scenario.
The company ran all the proper assessments and identified 15 IOPS per user as an acceptable number. (We’ll keep it simple and not go into the different profiles etc…) The company has also identified that it wishes to give each VM running Windows 7 2 GB of memory and 1 vCPU. Again, we are going to ignore application delivery and assume they have that figured out. The company has also identified that they wish to use shared storage in the form of a SAN and have taken the proper steps to avert bootup and login storms as well as anti-virus storms, etc…
Gekko wants to use blade technology to support this environment and its calculations and risk factors accept 60 VMs per host. The math would be as follows:
1000 VMs / 60 VMs per host = 16 hosts
Considering 2GM memory per VM, this would translate into 120GB (128 of course is the right configuration) memory per host. The following tables show the TCO.
Table 1. Desktop Virtualization TCO Table 2. Physical Desktop Rollout TCO
When reading these numbers, you can of course draw your own conclusions. Still, I want to discuss a few here and invite comment from you.
Now keep in mind I have put a lot of thought into this, so read the numbers carefully. I have also been very generous with these numbers.
For example, you can get more and better special pricing on servers from manufacturers than you can on desktops. Also note that I listed the cost of acquiring 1,000 new thin clients as optional, simply because you can turn your existing 7-year-old machines into thin clients and use them until they break, and so on.
I did want to list the cost of acquiring 1,000 new thin clients because I was always criticized about ignoring that number. So, for new companies that are just being formed that want to deploy desktop virtualization and have no equipment I have taken that into consideration as well.
I have provided these numbers to ruffle some feathers and stir up some healthy conversation and invite comment to get everyone’s perspective, I really would love to take the pulse of our readers as it pertains to desktop virtualization cost.

Citrix and The Atrix - 2011.09.09
For the past 18 months, I have been speaking publicly about desktop virtualization, and at every conference I keep stressing the inevitability of the smartphone making a significant impact on desktop virtualization.
If we break down the components of a smartphone today, we end up with a mini-computer. If I have that much power in the palm of my hand, why can’t I use it to power other devices? Why can’t I use it as a thin client? Except, the smartphone has an advantage over traditional thin clients, it has a 3G or 4G signal which means it has built-in internet access. Now if I have Internet access anywhere I go, I can access my DVI (Desktop Virtualization Infrastructure) desktop from anywhere, anytime. Now that is cool. However, let’s take it one step further, instead of the concept of Bring Your Own PC (BYOP), let’s keep the same acronyms but say Bring Your Own Phone. Now organizations can spend money to purchase these smartphones and have docking stations at desks that extend them to monitors and keyboards. Connect them to Wi-Fi at work. Do we really need to be wired to the desktop? No, that saves on switching infrastructure and cabling and much more while investing more in wireless access points.
The Motorola Atrix 4G is a huge step in the right direction for DVI enthusiasts and the fact that Citrix supports the device with the Citrix Receiver reinforces its advanced position in this market. Organizations are on the verge of a Windows 7 upgrade and a hardware refresh on desktops as well. Some are even on the verge of a mobile phone upgrade for users. A pretty large undertaking. What if they change their way of thinking a bit and instead of refreshing everything, refresh the phones with the Atrix or the likes of Atrix? The peripherals like keyboard, mouse and monitor should be pre-existent – all you have to do is build an infrastructure that can support DVI and the question of off-line access has solved itself.
Instead of finding a way to enable users to work offline, we found a way to keep users online with fewer devices and no complex setups. Sure, one can argue that on a plane, we still don’t have signal, but one can also argue that more and more planes have Wi-Fi nd it is just a matter of time before it becomes standard. Let’s face it: we live in a connected world, let’s change our way of thought and move forward, being off-line is not an option anymore. While that may have been the case 10 years ago, it is not today. Today, if you are not connected, you are not productive.
The Atrix is just the beginning, the next step will be to create shells for the phone, for example, why should I buy an iPad? Why can’t I just buy a shell that looks like the iPad and slide my iPhone in it to light up all the features of an iPad? Why can’t I get into my car, slide my phone in and that lights up my navigation and everything else I get from my in-car entertainment system today?
Tablets are not the future, you know what is? Smartphones.
