Aug 29, 2016 · Selected for the caching tier, the PM1725 SSD allows enterprise scale-up storage systems to fully utilize the low latency and extremely high efficiency of the NVMe interface. VMware Virtual SAN (VSAN) was first introduced in vSphere 5.5. It is a hybrid storage system that aggregates local SSDs and hard disk drives to provide a clustered datastore to be used by virtual machines in an vSphere environment. SSDs are used as a read cache and write buffer, while HDDs are used as persistent storage. It is a solid state disk with an additional non volatile cache memory. That cache is build up of Optane memory, which is slower than DRAM, but faster than flash memory, and non volatile too. Its easy for Windows users - there is the preinstalled Intel RST-Driver, which setups the Optane memory as cache for the SSD.
