VirtuCache Improves Hadoop Performance within VMs at Stanford

Typically Hadoop workloads are run on bare-metal servers. However since Stanford’s School of Medicine was 100% virtualized, and because their security, monitoring & management tools were integrated within VMware, it was easier for them to deploy Hadoop within VMs, instead of provisioning new physical servers.

The biggest challenge Stanford faced with Hadoop VMs was low throughput and high latencies for writes to disk.

Deploying VirtuCache resulted in write latencies in Hadoop reducing to an eighth of what they were before.

VirtuCache Improves Performance of Healthcare Imaging Application deployed in VMware VMs

EHR, imaging, analytics, desktop & application virtualization applications are prone to storage performance issues in VMware, that are easily solved with VirtuCache.

VirtuCache Improves the Performance of Equallogic Appliances for VMware VMs and Bare-Metal Linux Servers

By deploying VirtuCache in Dun & Bradstreet's VMware environment, we demonstrated sub 10ms VM latencies for high, write-intensive, random storage IO, which in turn facilitated the P2V of their database servers.
