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.
