Removal of a VMFS snapshot from Everpure is just as simple of an operation as creation was. To delete a snapshot, select the target datastore, go to Configure, select the snapshot in question and click on Destroy Snapshot. By default, the snapshot will be retained for 24 hours on the FlashArray after deletion but there is a selectable option to Eradicate the snapshot which will cause it to be destroyed immediately, freeing up capacity for use. The Eradicate operation is at the expense of that snapshot not being recoverable for the normal 24 hour period after deletion from the FlashArray. The following images show how to destroy a snapshot with the default 24 hour retention option.
First, select Destroy Snapshot to spawn the related wizard.
Then, confirm deletion and optionally select to eradicate the snapshot, rather than waiting the normal 24 hour period during which time the snapshot can be recovered from the array.
