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. When you calculate the volume
capacity, round the value up to the second decimal place.

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 shown in the following table:

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 = 5.55 TB
