Ldev Capacity; Calculating Lu Capacity (Open-3 Example); Ldev Capacity Information For Each Emulation Type - HP StorageWorks XP12000 User Manual

Figure 61 shows the relationship of the minimum LDEV capacity, base LDEV capacity, minimum data area
capacity, base data area capacity, and control information area capacity.

LDEV capacity

Figure 62 shows how to determine the volume capacity using the example of the OPEN-3 case.

Calculating LU capacity (OPEN-3 example)

Table 26 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.
