Capacity List for Each Emulation Type
This section explains the LDEV capacity and volume capacity for each emulation type in the units of
blocks and cylinders.
In this section, the numbers of cylinders are calculated from the following formulas.
For 3380 mainframe volumes: 1 cylinder = 1,440 blocks
For 3390 mainframe volumes: 1 cylinder = 1,740 blocks
The minimum data area capacity, the base data area capacity, and control information area capacity
for each emulation type are listed in the
on page 130. For the OPEN-L emulation type, CVs
cannot be created. Therefore, the base data area capacity and minimum data area capacity for OPEN-L
emulation type are the same. For the OPEN-V emulation type, the base data area capacity is not listed
because there is no concept of the base data area capacity.
The base LDEV capacity, the minimum LDEV capacity, the maximum external volume capacity, and the
number of LDEVs that can be defined for the external volume with maximum capacity are listed in the
on page 131. For the OPEN-L emulation type, the base LDEV capacity and the minimum LDEV
capacity are the same, because CVs cannot be created. For the OPEN-V emulation type, the base LDEV
capacity is not listed because there is no concept of the base LDEV capacity.
