where

calculated-entire-capacity-of-a-CV(slots)

means the entire capacity of a CV

if the data protection level is set to the Enhanced mode on the SATA drive.

If the CV capacity unit is block:

To calculate the entire capacity of a CV whose capacity unit is defined as block:

user-specified-a-CV-capacity / 2 / capacity-of-a-slot

where

capacity-of-a-slot

is expressed in kilobytes. The capacity of a slot depends on volume

emulation types (see

“Capacity of a slot” (page 50)

).

The resulting entire capacity is expressed in slots.

To calculate the management area capacity:

ceil(entire-capacity-of-a-CV(slots) /
calculated-management-area-capacity) * boundary-value

where

the value enclosed in ceil( ) must be rounded up to the nearest whole number.

calculated-management-area-capacity

depends on volume emulation types and

RAID levels (see

“Management area capacity of an open-systems volume” (page 49)

).

To calculate the entire capacity of a CV if the data protection level is set to the Enhanced mode
on the SATA drive:

ceil(entire-capacity-of-a-CV(slots) + calculated-management-area-capacity)

To convert the resulting entire capacity into blocks:

calculated-entire-capacity-of-a-CV(slots) * capacity-of-a-slot * 2

where

calculated-entire-capacity-of-a-CV(slots)

means the entire capacity of a CV

if the data protection level is set to the Enhanced mode on the SATA drive.
