Figure 26 Determining the capacity required for the external volume (OPEN-3)
When the capacity of the external volume is 1,610,612,640 (Blocks) and this external volume is
mapped with OPEN-3 emulation type, 334 LDEVs, each of which has the base LDEV capacity,
can be created at the maximum because the base LDEV capacity of OPEN-3 is 4,818,240 (Blocks).
When 334 LDEVs are created, 1,320,480 (Blocks) of the mapped external volume becomes the
free space. LDEVs can be created in the free space by using the VLL function.
Capacity list for each emulation type
This section explains the LDEV capacity for each emulation type in the units of blocks and cylinders.
The numbers of cylinders are calculated using 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
. 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 maximum
capacity of LDEVs whose emulation type is OPEN-V that can be created in the external volume is
listed as the base data area capacity.
