There are only a few applications, financial trading software being one example, that require very low latencies, lower even than what’s possible with an all-flash array (AFA). VirtuCache caching to in-host RAM results in lower VM latencies than an AFA. This is because RAM latencies are an order of magnitude…

Dell’s PowerEdge VRTX hyper-converged appliance can either have all hard drive datastores or all SSD datastores, but you can’t have SSDs act as tiering or caching media for VRTX volumes. That’s where VirtuCache comes in.
Creation Museum in Kentucky, USA is a museum about Bible history and creationism. Their storage needs were typical of a museum, requiring large amounts of storage for digital multimedia content related to the various exhibits at the museum.
April 29, 2020: By caching all VM read and write operations to Intel Optane NVME SSDs installed in VMware hosts, latencies of VDI VMs was much reduced. This resulted in improved VM performance and quicker VM boot times.
Cloud.com provides cloud and infrastructure orchestration software for service providers. They have an extensive internal dev/ops environment. Cloud.com wanted to re-purpose few of their expensive Dell C6220 servers to run additional applications, which meant that they needed to increase the number of existing VMs deployed on each host. As is…
Host side caching software needs to accelerate both reads and writes especially in light of increasing competition from all-flash arrays. Caching writes is important even for workloads that are read intensive. If we were not to accelerate writes, the reads behind the writes on the same thread will not be…
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…
EHR, imaging, analytics, desktop & application virtualization applications are prone to storage performance issues in VMware, that are easily solved with VirtuCache.
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.
