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.
Hedvig, the Santa Clara software defined storage (SDS) start-up now in its third year, has announced the infusion of a cool $21.5 million in Series C venture funding as attention increasingly turns to the fragmented SDS market, predicted to surpass $7 billion by 2020.
