Capacity by volume

Monitor the total provisioned capacity of your volumes to identify the volumes that have sufficient capacity to meet your storage needs.

The following key capacity metrics provide information about storage usage and the availability of capacity for storing data:

Capacity (GiB): The provisioned capacity of the volume.
Used Capacity (GiB) and Used Capacity (%): The amount of provisioned capacity that is taken up by written data in a thin-provisioned volume after data reduction techniques are applied.; Unlike thin-provisioned volumes, which use capacity when it is needed, the capacity that is provisioned to standard-provisioned volumes is fully allocated and is no longer available to the pool. That is, the Used Capacity (%) of standard-provisioned volumes is reported as Fully Allocated and the Used Capacity (GiB) is the same value as the provisioned capacity.; Available for: All storage systems, except IBM FlashSystem A9000 and IBM FlashSystem A9000R.
Available Capacity (GiB): The difference between the provisioned capacity of the thin-provisioned volume and the used capacity of the thin-provisioned volume.; Because the pool's capacity is dedicated to the standard-provisioned volume, the Available Capacity (GiB) is reported as 0.00.
Tier Distribution (%): For storage systems that support Easy Tier®, the distribution of capacity for the volume extents across each drive class or tier.
