When to consolidate and when to delete VM snapshots in VMware

'Consolidate' and 'Delete' terms still confuse many of my fellow experienced IT Professionals. Let me try to explain the difference in simple words: Consolidate option was made available from VSphere 5.x onwards and prior to which we had only 'Delete' snapshots option. Consolidation searches for hierarchies or delta disks to combine without violating data dependency i.e deletes all the redundant 'redo' logs which saves space in datastore and increases VM performance. This operation 'does not' delete the snapshots! Delete / Delete All will actually delete the snapshots and changes present of the delta disks will be written back to the parent disk (flat.vmdk). Please think twice before deleting the snapshots as it require space to be available in datastore. Make sure you have 'snapshot size(delta file) + its parent disk size' space free in datastore, atleast. Snapshot deletion process and space requirement in datastore is...

Space requirement in datastore to delete snapshot(s)

In this post, I will explain the snapshot deletion process in VMWare 4.0 and VI infrastructure 3. Suppose we have 3 snapshots of 10, 30 and 20 GB respectively. When you click on delete snapshot, following happens: - > A snapshot helper is created which holds all the changes. - > Snapshot 3 will be copied to snapshot 2 and snapshot 2 might grow upto 50 GB - > Snapshot 2 will be copied to snapshot 1 and will grow till 60 GB - > Snapshot 1 will be committed to the original VM Disk file (flat.vmdk) - > Helper snapshot disk will be committed to the original disk. - > All snapshots will be deleted. Snapshot deletion procedure: Please note, when snapshots are created, original vmdk file becomes 'read-only' and all the changes made after are written to separate 'delta' disks. This process changed in later version on VSphere 4.1 (and above), each snapshot gets merged to parent disk individually i.e. extra free space is...
