B-4 Required Volume Capacity for each Emulation Type
Hitachi Universal Storage Platform V/VM Universal Volume Manager User’s Guide
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.
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 Table B-2.
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 Table B-3. 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.
