Calculating Licensed Capacity For An External Volume - Hitachi VSP G200 System Administration Manual

Estimated required capacity

Calculating licensed capacity for an external volume

Use the following equation to calculate the licensed capacity for an external
volume:
External Volume Capacity (KB) = Volume Capacity (number of
blocks) X 512 (bytes) / 1,024
Calculating pool capacity
The license capacity of Dynamic Provisioning is calculated using the total
capacity of the Dynamic Provisioning pool. If you use Dynamic Provisioning
V-VOLs as P-VOLs or S-VOLs of ShadowImage, TrueCopy, Universal
Replicator, or global-active device, the license capacity of ShadowImage,
TrueCopy, Universal Replicator, or global-active device is calculated by using
the page capacity allocated to the Dynamic Provisioning V-VOLs (that is, used
pool capacity).
For more information on calculating pool capacity, see the Provisioning Guide.
Accelerated compression-enabled parity group capacity
For the actual capacity of accelerated compression-enabled parity groups, the
total capacity of LDEVs created in the parity group and the physical capacity
are compared. The one with the least capacity is added as the actual
capacity. See the following table for an example.
Total LDEV capacity in the parity
group

Managing licenses
Use the Licenses window in the maintenance utility to install and uninstall
block license keys.
