Estimating Licensed Capacity Based on Used Capacity

There are three capacities to use for estimating the licensed capacity, depending on the program
product option:
Normal volume capacity
The method to calculate normal volume capacity depends on the volume emulation types.

Volume Emulation Type
3380-x
3390-x
OPEN-x
