Only read performance is improved by HP MSA's internal caching and tiering features.1 In comparison, VirtuCache improves the performance of reads and writes for MSA, and it does so by caching to in-VMware host SSD or RAM. There are other differences as well.

As it relates to storage, genome sequencing workflow has two requirements.
Need for cheap ($/GB) Petabyte scale storage.
Need for faster processing of Genome files under analysis, many of which are a few hundred GB in size.

VirtuCache is installed in VMware vSphere kernel. It then automatically caches frequently and recently used data from any backend storage to any high speed media (RAM/SSD) in the VMware host. By bringing large amounts of 'hot' data closer to the VMware host GPU and CPU, VirtuCache improves the performance of all applications running within VMs including GPU assisted operations.

City of Mountain View is using VirtuCache to improve the performance of Netapp's Ontap Select storage software. They were one of our first customers to upgrade to ESXi 7.0 and so they had to upgrade VirtuCache as well.
We announced General Availability of VirtuCache for ESXi 7 within 2 weeks of VMware's ESXi 7 release date.
