VMFS Datastore Versions

Found a good VMware KB article that summarizes the different versions of VMFS, and what the implications are in a mixed environment of ESX 3 and 4. Short answer-nothing!

Basic Jist-

  1. only way to upgrade the minor version is to re-init and format.
  2. all versions of VMFS since ESX 3.0 up to ESX 4.1 are all compatible with each other, so until they release VMFS v4 you really shouldn’t every worry about this again.

Nice and Easy. I Like!
