Reclaimable Storage
Reclaimable Storage
-
The Reclaimable Storage page shows block and file objects that may no longer be in use. Reclaimable storage is supported for PowerStore, PowerMax or VMAX, PowerVault, the Unity XT family, and SC Series systems. It shows the total number of storage objects and the total amount of potentially reclaimable space across all systems. The following rules are used to identify potentially reclaimable storage:
- Block Objects with no frontend I/O activity in the past week or longer
- File Objects with no frontend I/O activity in the past week or longer
- Block Objects with no hosts attached
- Block-based virtual machines that have been shut down for at least a week
- File-based virtual machines that have been shut down for at least a week
Note: The Reclaimable Storage report intelligently filters out objects that are array-based replicas, because those replicas are not attached to hosts and do not have frontend I/O.
The Group By drop-down menu allows the user to group the storage objects by system or by the rule types mentioned above.
Group by System (Default) shows the total number of storage objects and reclaimable space per system. A more detailed view of the objects identified under each rule can be seen by selecting the line item to expand to display the associated details.
The Filter button allows the user to filter the results based on System or Rule Type.
The Group by Rule Type shows reclaimable storage for each rule. In this view, the total number of storage objects and reclaimable capacity is summarized for each rule.
