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:
Caution: If 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 .
Table 9 Licensed capacity types
Type 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.
