1 If you use V-VOLs of Thin Provisioning 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 (i.e., used pool capacity).
Calculating licensed capacity for a normal volume
The calculation of the normal volume capacity depends on the volume emulation type. Use the
formula in the following table to estimate capacity for purchase.
Table 20 Methods for calculating capacity of a normal volume
Formula for calculating capacity of a normal volume Volume emulation type
720 KB X (number of user cylinders) 3380-x
870 KB X (number of user cylinders) 3390-x
Same as the capacity specified when creating the volume OPEN-x
Note: In the left column of this table, "x" indicates a number or a letter. For example, OPEN-x refers to emulation types
such as OPEN-3 and OPEN-V.
An example is provided in the following table.
Table 21 Example of estimating capacity for purchase
Value Item
3390-3 Volume emulation type
3,339 Number of user cylinders
2,048 Number of volumes
870 KB X 3,339 X 2,048 = 5,949,296,640 KB Total capacity of all the volumes
5,949,296,640 KB / 1,024 = 5,809,860 MB
5,809,860 MB / 1,024 = 5,673.70 GB
5,673.70 GB / 1,024 = 5.54 TB
At lease 6 TB Estimated capacity for purchase
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 HP P9000 Provisioning for Open
Systems User Guide.
