Use this formula to calculate the entire capacity of a CV (emulation types 3390-XA, 3390-XB, 3390-XC). The resulting CV capacity is expressed in megabytes.
Note:
- 3390-XA indicates 3390-3A, 3390-9A, 3390-LA, and 3390-MA.
- 3390-XB indicates 3390-3B, 3390-9B, 3390-LB, and 3390-MB.
- 3390-XC indicates 3390-3C, 3390-9C, 3390-LC, and 3390-MC.
( ceiling( ( (user-specified-CV-capacity + management-area-capacity) * 15 * capacity-of-a-slot) / boundary-value) * boundary-value) / 1024
where:
- The value enclosed in ceiling( ) must be rounded up to the nearest whole number.
- The user-specified-CV-capacity (expressed in cylinders) is the capacity of the user area in the CV.
- The management-area-capacity (expressed in cylinders) depends on the volume emulation type.
- The capacity-of-a-slot (expressed in kilobytes) is 58 KB for all mainframe volume emulation types.
- The boundary-value (expressed in kilobytes) depends on the volume emulation type and RAID level (see Boundary values of volumes).
