Figure 70 LDEV capacity
Figure 71 (page 161) shows how to determine the volume capacity using the example of the OPEN-3
case.

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.
Table 35 (page 162) lists the minimum data area capacity, base data area capacity, and control
information area capacity for each emulation type. 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.
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
