Cormac Hogan of VMware Storage comments:
I learnt something interesting about Virtual Volumes (VVols) last week. It relates to the way in which snapshots have been implemented in VVols. Historically, VM snapshots have left a lot to be desired. So much so, that GSS best practices for VM snapshots as per KB article 1025279 recommends having on 2-3 snapshots in a chain (even though the maximum is 32) and to use no single snapshot for more than 24-72 hours. VVol mitigates these restrictions significantly, not just because snapshots can be offloaded to the array, but also in the way consolidate and revert operations are implemented.
With the general release of vSphere 6.0 yesterday, you should brush up on your VVols knowledge. Cormac is just the person to help you with that.
