View efficiency space savings

Contributors netapp-dbagwell dmp-netapp

You can view the amount of space savings achieved through deduplication and data compression on a volume. You might do this to assess the effectiveness of your administrative processes or as part of capacity planning.

About this task

You need to use the command volume show to display the space savings on a volume. Note that the space savings in Snapshot copies is not included when calculating the space savings achieved on a volume. Using deduplication does not affect volume quotas. Quotas are reported at the logical level and remain unchanged.

Steps
  1. Use the volume show command to view space savings achieved on a volume using deduplication and data compression.

Example

The following command enables you to view the space savings achieved by using deduplication and data compression on volume VolA: volume show -vserver vs1 -volume VolA

cluster1::> volume show -vserver vs1 -volume VolA

                                 Vserver Name: vs1
                                  Volume Name: VolA
