Flash Read Cache™ can accelerate virtual machine performance by using host-resident flash devices as a cache.
A local flash device becomes unavailable for virtual flash resource or Virtual SAN configuration when it is formatted with VMFS or any other file system.
Flash Read Cache does not support RDMs in physical compatibility. Virtual compatibility RDMs are supported with Flash Read Cache.
