You are presented with the same Smart Copy options to Include PS Series
volumes accessed by guest iSCSI initiators and whether or not to perform
virtual machine memory dump.
In addition to the Smart Copy options, there is a Retention policy to specify the
maximum number of Smart Copies to keep. This will allow for a rolling
schedule to keep a particular number of Smart Copies and roll them over when
the oldest one expires. There must be sufficient snapshot space available to
accommodate all of these Smart Copies.
NOTE: With Dell EqualLogic PS Series Firmware v6.x you can enable snapshot
borrowing on the volume to allow for borrowing from unused snapshot space
belonging to other volumes or from the free pool space to allow for the
retention policy to be met in the event that the volume does not currently have
sufficient snapshot reserve to keep all of the keep count Smart Copies. For
more information on snapshot borrowing please refer to TR1084 EqualLogic PS
Series Architecture: Snapshot Space Borrowing Overview.
