Software and licensed capacity

Three licensed capacity types are available. The one you choose depends on the software application. The following tables describe the licensed capacity types:

CautionIf you use Dynamic Provisioning, the licensed capacity might become insufficient because the used capacity of Dynamic Provisioning pools could increase, even if you do not add any volumes. If this happens, you must purchase an additional license within 30 days to increase the capacity to match the new volume size. For instructions to calculate pool capacity, see the Provisioning Guide.

Description

Used capacity

The licensed capacity is calculated by using one of the following capacities:

  • Normal volumes (volumes)
  • External volumes mapped to the storage system
  • Pools

If the pool contains pool volumes that belong in accelerated compression-enabled parity groups, you must purchase physical capacity of the pool for the license capacity.

Mounted capacity/usable capacity

The licensed capacity is estimated by using the capacity of all the volumes in the storage system.

When you estimate for the capacity of the accelerated compression-enabled parity groups, the physical capacity of the parity group is the maximum of the estimated capacity, even if you created an internal volume which exceeds the physical capacity of the accelerated compression-enabled parity group. See the Provisioning Guide for an explanation of accelerated compression.

Unlimited capacity

You can use the software regardless of the volume capacity.

Note:

  1. The method for calculating the licensed capacity varies depending on the software contained in each software bundle.
  2. The used capacity for Remote Replication is the sum of TrueCopy and Universal Replicator.
  3. VSP G100 does not support Disaster Recovery Extended.
