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 Thin Provisioning is calculated using the total capacity of the Thin Provisioning
pool. If you use Thin Provisioning V-VOLs as P-VOLs or S-VOLs of Business Copy/Continuous Access
Synchronous/Continuous Access Journal, the license capacity of Business Copy/Continuous Access
Synchronous/Continuous Access Journal is calculated using the page capacity allocated to the Thin
Provisioning V-VOLs (that is, used pool capacity).
For more information on calculating pool capacity, see the XP P9000 Provisioning for Open Systems User
Guide and XP P9000 Provisioning for Mainframe Systems User Guide.
