NOTE:
◦
The value enclosed in two upward arrows ( ) must be rounded up to the nearest whole
number.
◦
The user-specified CV capacity is expressed in blocks.
◦
The boundary value is expressed in kilobytes. The boundary value depends on the volume
emulation types and RAID levels (see
“Boundary Value for Each RAID Level” (page 17)
).
If the data protection level is set to the enhanced mode on a SATA drive, the boundary
value depends on the volume emulation types and RAID levels (see
Each RAID Level (Data Protection Level is Set to Enhanced Mode on SATA Drive)”
(page 17)
).
Size Calculation of Fixed-Size Open-Systems Volumes
•
If the unit for CV capacity is MB (megabytes):
To calculate the user area capacity of a CV, use the following formula. The resulting user area
capacity is expressed in kilobytes.
user-specified-CV-capacity Ч 1024 ч capacity-of-a-slot ч 15 Ч capacity-of-a-slot × 15
NOTE:
◦
The value enclosed in two upward arrows ( ) must be rounded up to the nearest whole
number.
◦
The user-specified CV capacity is expressed in megabytes.
◦
The capacity of a slot is expressed in kilobytes. The capacity of a slot depends on the
volume emulation types (see
“Capacity of a Slot” (page 18)
).
To calculate the entire capacity of a CV, use the following formula. The resulting entire capacity
is expressed in megabytes.
(user-area-capacity + management-area-capacity) ÷ boundary-value × boundary-value ÷
1024
NOTE:
◦
The value enclosed in two upward arrows ( ) must be rounded up to the nearest whole
number.
◦
The user area capacity is expressed in kilobytes.
◦
The management area capacity is expressed in kilobytes. The management area capacity
depends on the volume emulation types (see
).
◦
The boundary value is expressed in kilobytes. The boundary value depends on the volume
emulation types and RAID levels (see
). If the data protection level is
set to the enhanced mode on a SATA drive, the boundary value depends on the volume
emulation types and RAID levels (see
“Boundary Value for Each RAID Level (Data Protection
Level is Set to Enhanced Mode on SATA Drive)” (page 17)
).
•
If the unit for CV capacity is block:
To calculate the user area capacity of a CV, use the following formula. The resulting user area
capacity is expressed in kilobytes.
