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.
Table 21 Formulas 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 shown in the following table:
Table 22 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 = 5.55 TB
At lease 6 TB Estimated capacity for purchase
