Client Virtualization the HP Way

What’s driving customers to bigger and bigger desktop virtualization initiatives? What are the challenges they face, and what can be done to resolve hurdles, and speed customers on their way to better client virtualization infrastructures that actually deliver the benefits that attract them to desktop virtualization in the first place?

No doubt, desktop virtualization, or “client virtualization” in HP parlance, roared off to a thunderous start, and the industry has already seen many big initiatives and offerings. Moving into 2012, client virtualization increasingly looks to have the wherewithal to go entirely mainstream, and move into a much broader set of customers than the initial high profile adoptees who had unusual business needs or were turning up unique hosted services. Yet client virtualization remains a complex undertaking. HP thinks they have a clear understanding of that complexity, and a consequent solution approach built to eradicate that complexity from the equation. In turn, they aim to make the promises of client virtualization more compelling than ever, and allow customers to be certain of realizing those promises. In this solution profile, Taneja Group will take a look at the promises driving client virtualization, the challenges that too often pull those promises apart, and then look at how HP is driving those challenges out of the equation with a newly announce product – VirtualSystem CV2.

Much Sizzle At EMC WORLD 2012

I spent three days at EMC World, the longest time I have ever spent on a one-vendor show. It was exhausting. And thrilling. I know most bloggers will write about the 42 products EMC announced with fanfare at the show. As will several of my team members. And that is all good. But I was more interested in where EMC is at, relative to the market and where is it heading. NetApp recently announced good numbers for the quarter but a lower forecast for the next quarter. HP announced significant layoffs, even if it is not clear how big the impact was on the storage side (we suspect little since storage is a lonely bright spot for HP). Dell's storage numbers are down quarter over quarter. Yet EMC is showing bullish numbers all around. Why is this? What magic does EMC possess that others don't? Here is the way I see it.

HP 3PAR StoreServ Double Density: Delivering twice the VM density versus traditional arrays

Why does storage performance matter? There are few storage administrators who have not witnessed an unhappy moment where lack of storage performance brought an application to its knees. But quantifying how storage performance matters, aside from serving as insurance to avoid an application crippling moment, is a tricky proposition.

One way is in terms of how storage performance determines the efficiency of the infrastructure. When all else is equal and well tuned – hypervisors, servers, networks – then storage becomes a precious commodity that can determine just how many workloads or applications a given infrastructure can support, and therefore how efficiently it can operate at scale.

When it comes to virtualization, this workload density has serious impacts, but fortunately is even easier to assess. A number of years ago, Taneja Group started out testing workload density among competitive hypervisors, and we labeled it VM density – a measure of how many VMs similar systems can run without compromises in performance or usability. Our net findings clearly indicated how big of an impact a small difference in VM density can have. When poor VM density makes it necessary to add more servers and hypervisors, the cost of servers is costly enough, but licensing tools like vSphere suites can add up to many thousands of dollars and dwarf hardware costs. Meanwhile, with more servers/hypervisors comes more complexity and management overhead, along with operational data center costs (power, cooling, floorspace). The consequences can easily run to tens of thousands of dollars per server. At large scale, superior VM density can easily add up to hundreds of thousands or millions of dollars for a business.

We’ve long suggested that storage performance is one of the biggest contributors to VM density, but few vendors have been brave enough to step forward and declare that their own storage system can take VM density farther than anyone else’s. Well times have changed.

Approximately 6 months ago, HP made a bold promise with their 3PAR storage systems – guaranteeing that customers moving to HP 3PAR storage, from traditional legacy storage, will double the VM density of their existing server infrastructure. Better yet, HP’s promise wasn’t about more spindles, but rather the efficiency and power of their 3PAR StoreServ storage controller architecture – they made this promise even when the customer’s old storage system contained the same disk spindles. Our minds were immediately beset with questions – could a storage system replacement really double the workload density of most virtual infrastructures? We knew from experience that most customers are indeed IO constrained, we’ve had at least several hundred conversations with customers fighting virtual infrastructure performance problems where at the end of the day, the issue is storage performance. But a promise to double the density of these infrastructures is indeed aggressive.

It goes without saying that at Taneja Group, we were more than eager to put this claim to the test. We approached HP in mid-2012 with a proposal to do just that by standing up a 3PAR StoreServ storage array against a similar class, traditional architecture storage array. The test proved more interesting when HP provided us with only the smallest of their 3PAR StoreServ product line at that time (an F200) and a competitive system made up of the biggest controllers available in another popular but traditional architecture mid-range array. Moreover, that traditional system, while first entering the market in 2007/2008, could still be purchased at the time of testing, and is only on the edge of representing the more dated systems envisioned by HP’s Double Density promise. 

Our Findings: After having this equipment made available for our exclusive use during several months of 2012, we have a clear and undeniable conclusion: HP 3PAR StoreServ storage is quite definitely capable of doubling VM density versus typical storage systems.

HP 3PAR StoreServ 7000 - Enterprise for the Mid-range

Over the past couple of years the mid-range storage market has become a hotbed of on-going innovation. We’ve watched as products have entered the market from all sides – large vendors as well as the newest, hottest startups. Yet many of the apparently pioneering announcements leave the mid-market customer facing on-going challenges. A storage system is a foundational element of the IT infrastructure on top of which the rest of a business’s IT is deployed. For many, even the cutting edge solutions just coming to market lack in one or more critical dimensions. Typically, those shortcomings arise around critical elements of scalability or resiliency, forcing the organization to pursue complex workarounds to compensate. Customers too often settle for capacity at the cost of resiliency, and in turn weave together multiple systems and parts, such as replication, management, and even heterogeneous virtualization tools to try to offset the shortcomings. Other times, the mid-range customer has been undone simply by a demand for capabilities that bring with them far more complexity than the mid-range customer can take on. Even just ensuring that a system can perform sufficiently and scale with demand often mandates complex underlying configuration semantics, and significant expertise in managing disk groupings, extents, RAID levels, and more.

In reality, the mid-market demands enterprise capability – performance, resiliency, and features – but with an innovative level of simplification and a unique level of adaptability. Moreover, the mid-market is tremendously big, with a wider diversity of customers and needs than in the large enterprise. Building the biggest possible storage has long satisfied the sweet spot of enterprise customers. But in the mid-range, one customer may need smaller than a vendor can profitably build, while the next customer needs something bigger. More importantly, each of those customers may grow and change fast, and they need a storage system that can do likewise. It isn’t a sufficient answer to offer ten different products that each must be periodically replaced.

When we survey mid-range storage systems, we look at 5 key criteria (Table 1) that represent this intersection of challenges. Together, they make a complex recipe for established or new-coming vendors alike. But the bigger part of the challenge by far rests in carefully balancing that recipe without compromising any particular dimension, and then delivering the right price point to suit the mid-market of SMB and SME customers. An enterprise-class mix really requires enterprise-class architecture, but such an architecture can hardly be delivered at the right price points.

In an unusual twist, HP recently announced a new mid-market storage system built on 3PAR technology and preserving the same foundational enterprise-class architecture found beneath other HP 3PAR storage arrays that have long supported some of the largest IT infrastructures around. By preserving this architecture, advancing their reputational ease of use even further, and then packaging features and capabilities for the mid-market, HP has set their sights on delivering just what the mid-market demands: enterprise-class, but packaged for the mid-market customer. In this product-in-depth, we’ll take a look at the underpinnings of the HP 3PAR StoreServ 7000 family, and how and whether it comes together to deliver against these fundamental mid-market criteria.

HP Discover - Destinations for Convergence

As an unusual exception to precedent, Taneja Group finds ourselves at HP Discover this year. HP Discover tends to be a more in-depth and longer event than Taneja Group can historically cover, but the HP innovation portfolio continues to revolve around storage to such a degree it can't be missed. With feet on the ground in Las Vegas, what do we think we have to look forward to at Discover 2013?


Why VM Density Matters: HP Innovation Delivers Validated "2x" Advantage

Server virtualization brings a vast array of benefits ranging from direct cost savings to indirect improvements in business agility and client satisfaction. But for the IT investment decision-maker, it’s those measurable “hard” costs that matter most. Fortunately, virtualized environments deliver a quantifiably lower Total Cost of Ownership (TCO) compared to legacy physical infrastructures. Since we have all experienced the economic imperative to minimize TCO, it’s easy to understand why virtualization has been driven across significant percentages of modern data centers. Virtualization today is a proven, cost-effective, and nearly ubiquitous IT solution.

But the further challenge for IT investors now is to choose the best virtualization solution to get the “biggest bang for the buck”. Unfortunately the traditional cost per infrastructure (server CPU, storage GB, et.al.) metrics used to judge physical hardware are not sufficient buying criteria in a virtual environment. In a virtualized and cloudy world, cost per application comes closer to capturing the true value of a virtual infrastructure investment. For example, the more virtual machines (VMs) that can be hosted within the same size investment, the lower the cost per application. Therefore a key comparison metric between virtualization solutions is virtual machine (VM) density. All other things being equal (e.g. applications, choice of hypervisor, specific allocations and policies), an infrastructure supporting a higher VM density provides a better value.

As virtualization deployments grow to include active production workloads, they greatly stress and challenge traditional IT infrastructure. The virtualization hypervisor “blends up” client IO workloads and condenses IO intensive activities (i.e. migration, snapshots, backups), with the result that the underlying storage often presents the biggest constraint on effective VM density. Therefore it’s critically important when selecting storage for virtual environments to get past general marketing and focus on validated claims of proven VM density.

The HP Solution to Backup Complexity and Scale

There are a lot of game-changing trends in IT today including mobility, cloud, and big data analytics. As a result, IT architectures, data centers, and data processing are all becoming more complex – increasingly dynamic, heterogeneous, and distributed. For all IT organizations, achieving great success today depends on staying in control of rapidly growing and faster flowing data.

While there are many ways for IT technology and solution providers to help clients depending on their maturity, size, industry, and key business applications, every IT organization has to wrestle with BURA (Backup, Recovery, and Archiving). Protecting and preserving the value of data is a key business requirement even as the types, amounts, and uses of that data evolve and grow.

For IT organizations, BURA is an ever-present, huge, and growing challenge. Unfortunately, implementing a thorough and competent BURA solution often requires piecing and patching together multiple vendor products and solutions. These never quite fully address the many disparate needs of most organizations nor manage to be very simple or cost-effective to operate. Here is where we see HP as a key vendor today with all the right parts coming together to create a significant change in the BURA marketplace.

First, HP is pulling together its top-notch products into a user-ready “solution” that marries both StoreOnce storage and Data Protector. For those working with either or both of those separately in the past in conjunction with other vendor’s products, it’s no surprise that they each compete favorably one-on-one with other products in the market, but together as an integrated joint solution they beat the best competitor offerings.

But HP hasn’t just bundled products into solutions, it is undergoing a seismic shift in culture that revitalizes its total approach to market. From product to services to support, HP people have taken to heart a “customer first” message to provide a truly solution-focused HP experience. One support call, one ticket, one project manager, addressing the customer’s needs regardless of what internal HP business unit components are in the “box”. And significantly, this approach elevates HP from just being a supplier of best-of-breed products into an enterprise-level trusted solution provider addressing business problems head-on. HP is perhaps the only company completely able to deliver a breadth of solutions spanning IT from top to bottom out of their own internal world-class product lines.

In this report, we’ll examine first why HP StoreOnce and Data Protector products are truly game-changing on their own rights. Then, we will look at why they get even “better together” as a complete BURA solution that can be more flexibly deployed to meet backup challenges than any other solution in the market today.
