I often get asked if a certain version of vSAN can be deployed on a different version of vSphere. The answer is no. vSAN is built into the vSphere version. That means vCenter needs to be upgraded to the correct version of vCenter and all the hosts in the cluster need to be upgraded to the correct version of ESXi in order to get the features of that version of vSAN. Lastly, vSAN formats each disk drive with an on-disk format, so to get the full features of a specific release, you need to update the on-disk format.

Here’s basically how everything breaks down:

  • If you have vSphere 5.5 (vCenter Server 5.0 & ESXi 5.0) then you have vSAN 5.5.
  • If you have vSphere 6.0 (vCenter Server 6.0 & ESXi 6.0) then you have vSAN 6.0.
  • If you have vSphere 6.0 U1 (vCenter Server 6.0 Update 2 & ESXi 6.0 Update 1) then you have vSAN 6.1.
  • If you have vSphere 6.0 U2 (vCenter Server 6.0 Update 2 & ESXi 6.0 Update 2) then you have vSAN 6.2.
  • If you have vSphere 6.5 (vCenter Server 6.5 & ESXi 6.5) then you have vSAN 6.5.
  • If you have vSphere 6.5.0d (vCenter Server 6.5.0d & ESXi 6.5.0d) then you have vSAN 6.6.

Here’s a more detailed matrix:
