Depending on your ONTAP release, you can view the physical footprint savings on each volume. You might do this to assess the effectiveness of your administrative processes or as part of capacity planning.

About this task

Beginning with ONTAP 9.11.1, you can use the command volume show-footprint to view the physical footprint savings on volumes with temperature-sensitive storage efficiency (TSSE) enabled. Beginning with ONTAP 9.13.1, you can use the same command to view the physical footprint savings on volumes not enabled with TSSE.

Steps

  1. View the volume footprint savings:

    volume show-footprint
    Example output with TSSE enabled
          Vserver : vs0
      Volume  : vol_tsse_75_per_compress
