Emulation types other than OPEN-V
• 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:
• Round up the value enclosed by two up arrows (↑) 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 volume
emulation types (see Table 20 on page 46).
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:
• Round up the value enclosed by two up arrows (↑) 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 volume emulation types (see Table 18 on page 46).
• The boundary value is expressed in kilobytes. The boundary value depends on volume
emulation types and RAID levels (see Table 19 on page 46).
• 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.
user-specified-CV-capacity ÷ 2
NOTE: The user-specified CV capacity is expressed in blocks.
To calculate the entire capacity of a CV, use the following formula. The resulting entire capacity is
expressed in blocks. To convert the resulting entire capacity into megabytes, divide this capacity by
2,048.
↑ (user-specified-CV-capacity + management-area-capacity Ч 2) ч (boundary-value Ч 2) ↑ Ч
(boundary-value × 2)
NOTE:
• Round up the value enclosed by two up arrows (↑) to the nearest whole number.
• The user-specified CV capacity is expressed in blocks.
• The management area capacity is expressed in kilobytes. The management area capacity
depends on volume emulation types (see Table 18 on page 46).
• The boundary value is expressed in kilobytes. The boundary value depends on volume
emulation types and RAID levels (see Table 19 on page 46).
