Virtual Machines
Before Virtual Volumes, a deleted VM could be easily restored from a snapshot. However, with vVols, the delete occurs directly on the volume. Therefore, HPE has provided a "deferred deletion" functionality that allows you to restore or permanently delete VMs that have been used with vVols. The configuration vVol is preserved only if there is at least one unmanaged snapshot that can be used to restore from. The data vVol is preserved even if no snapshots have been taken.
