Reclamation views of storage systems

Use the reclamation view of storage systems for detailed information about the reclaimable storage in your environment. You can view the storage savings that can be made by reclaiming storage, including information about the volumes that can be reclaimed.

When you add a storage system for monitoring and schedule a storage systems probe, a reclamation analysis determines the volumes that can be reclaimed.

On the Reclamation > View by Storage Systems page, the reclamation information is displayed in the following format:

Reclamation donut chart

Blue area of the donut chart: Represents the amount of non-reclaimable used capacity.
Green area of the donut chart: Represents the amount of reclaimable space.
Show the data: If you defined storage tiers for the data center, to view the amount of storage that can be saved for each tier, hover the mouse pointer over the green area.
Center of the donut chart: Provides a rounded estimate of the storage capacity that can be saved when the volumes of the storage systems that are listed in the table are reclaimed.

Reclamation bar chart

Shows the amount of storage space that can be reclaimed on each storage system in your data center.

Reclamation chart legend

The bottom section of the reclamation view is a table that shows more information about the storage systems. Each row represents a storage system, and each column provides reclamation information about the storage system.

Information about storage systems

Use the following information for a detailed description of the columns in the table:

Used Capacity (GiB): (Previously known as Used Pool Space) The amount of usable capacity that is taken up by data in a storage system, after data reduction techniques have been applied.
Inactive Capacity (GiB): The amount of storage system space that did not have any I/O activity in the last 14 days.
Potentially Orphaned Capacity (GiB): The amount of storage system space that is not attached to any host and that is not the target in FlashCopy® relationships or remote copy relationships.
Reclaimable Percentage (%): The percentage of the total capacity of the storage system that can be reclaimed. This value is the Total Reclaimable Capacity divided by the Used Capacity.
Storage System: The display name of the storage system.
Total Reclaimable Capacity (GiB): The total amount of storage system space that can be reclaimed. This is the sum of the Inactive Capacity amount and the Potentially Orphaned Capacity amount for the storage system.
Volumes: The number of volumes on the storage system that can be reclaimed. Click the number to view which volumes can be reclaimed.
