Same as the capacity speciî ´ed when creating the
volume
Notes:
1. x indicates a number or a letter. For e
xample, OPEN-x refers to emulation types
such as OPEN-3 and OPEN-V.
An example is shown in the following table.
Table 13 Example of calculating license capacity
Item Value
Volume emulation type 3390-3
Number of user cylinders 3,339
Number of volumes 2,048
Total capacity of all the
volumes
870 KB × 3,339 × 2,048 = 5,949,296,640 KB
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 5.55 TB
Estimated required capacity At least 6 TB
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.
