vSAN – Setup and Configure Guide for vSphere 6

I personally am a huge fan of vSAN. Each new release of vSAN offers new improvements and functionality. As of right now Virtual SAN can deliver all-flash performance with up to 100,000 IOPs per host and can support vSphere availability technologies like High Availability (HA), asynchronous replication, stretched cluster capabilities, and storage efficiency features for all-flash including deduplication, compression and erasure coding.

Prerequisites and Notes

  1. Should have its own dedicated vSwitch
  2. Needs one SSD and two local disk total
  3. Needs a minimal of three host
  4. HA may need to be turned off temporary to activate vSAN for the first time. Once done you can go back and turn it back on.
  5. Other Host not participating can see the vSANdatastore as well
