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.

Flash Virtualization System: Powerful but Cost-Effective Acceleration for VMware Workloads

Server virtualization can bring your business significant benefits, especially in the initial stages of deployment. Companies we speak with in the early stages of adoption often cite more flexible and automated management of both infrastructure and apps, along with CAPEX and OPEX savings resulting from workload consolidation.  However, as an increasing number of apps are virtualized, many of these organizations encounter significant storage performance challenges. As more virtualized workloads are consolidated on a given host, aggregate IO demands put tremendous pressure on shared storage, server and networking resources, with the strain further exacerbated by the IO blender effect, in which IO streams processed by the hypervisor become random and unpredictable. Together, these conditions reduce host productivity—e.g. by lowering data and transactional throughput and increasing application response time—and may prevent you from meeting performance requirements for your business-critical applications.

How can you best address these storage performance challenges in your virtual infrastructure? Adding solid-state or flash storage will provide a significant performance boost, but where should it be deployed to give your critical applications the biggest improvement per dollar spent? How can you ensure that the additional storage fits effortlessly into your existing environment, without requiring disruptive and costly changes to your infrastructure, applications, or management capabilities?

We believe that server-side acceleration provides the best answer to all of these questions. In particular, we like server solutions that combine intelligent caching with high-performance PCIe memory, which are tightly integrated with the virtualization platform, and enable sharing of storage across multiple hosts or an entire cluster. The Flash Virtualization System from SanDisk is an outstanding example of such a solution. As we’ll see, Flash Virtualization enables a shared cache resource across a cluster of hosts in a VMware environment, improving application performance and response time without disrupting primary storage or host servers. This solution will allow you to satisfy SLAs and keep your users happy, without breaking the bank.
