Understanding Data Locality in VMware Virtual SAN

VMware Virtual SAN LogoSince the release of VMware Virtual SAN, I’ve been involved in numerous costumer and field conversations around the topic VMware Virtual SAN’s ability to take advantage of data locality.

I have addressed the question in several of the Virtual SAN presentations I have delivered, but I realized that this was an ongoing topic of discussion and one which we needed to provide more details in order to satisfy everyone that has been wondering about this topic.  I figured it was time to put together some form of OFFICIAL collateral providing in-depth  details around this topic.

So, like any storage system, VMware Virtual SAN makes use of data locality. Virtual SAN uses a combination of algorithms that take advantage of both temporal and spatial locality of reference to populate the flash-based read caches across a cluster and provide high performance from available flash resources.
