Space Reclamation
The
Space Reclamation
page allows you to manage space reclamation activity on the DXi6900. You can
start or stop space reclamation. You can also monitor the progress of space reclamation activity.
During space reclamation, the DXi6900 searches the blockpool for tags that are no longer referenced and
then deletes the unneeded tags to free up space.
In addition, the DXi automatically compacts reclaimable space in the following ways:
l
During data ingest, reclaimable space is compacted as needed to provide space for new, deduplicated
data.
l
If the DXi is not in Low Space state, compaction starts when used disk space reaches a high level and
there is sufficient reclaimable space. Compaction stops when used disk space falls below the high
threshold state. The reclaimed space can be used to store new deduplicated or non-deduplicated data.
