Disk Usage Graph

(DXi systems only)

The Disk Usage graph compares the amount of data stored on the DXi appliance after reduction, which includes deduplication and compression, to the allocated disk space on the appliance. Use the graph to monitor the amount of disk space that is made available during space reclamation.

Review the following variables of the Disk Usage graph.

Figure 1: Disk Usage Graph

Displays the first, last, and delta values for the variables displayed on the graph.

Displays the total amount of allocated disk space on the appliance. The value also includes disk space that is free to be reclaimed for storing new backup data.

Displays the amount of data that is not intended for deduplication. This value includes the amount of disk space used by shares or partitions that are not configured for deduplication.

Displays the amount of data that remains after ingested data is deduplicated and compressed. This value is the amount of data consumed by the blockpool. Use this information to see the amount of deduplicated, compressed data stored on the appliance.

Displays the amount of disk space available for storing new backup data. This newly freed space contained data that expired or was deleted from the appliance.

For non-deduplicated shares and partitions, the appliance can automatically free reclaimable space when all other free space has been allocated.

DXi versions 2.3 and newer can automatically free reclaimable space for deduplicated data on shares and partitions within the blockpool. This process leaves the free space available for subsequent deduplicated data on shares and partitions within the blockpool.
