Management area capacity – HP XP Data Shredder Software User Manual

NOTE:
◦
The value enclosed in two upward arrows ( ) must be rounded up to the nearest whole
number.
◦
The calculated management area capacities depend on the volume emulation types and
RAID levels (see
“Calculated Management Area Capacities” (page 18)
).
To calculate the entire capacity of a CV if the data protection level is set to the enhanced
mode on the SATA drive, use the following formula:
entire-capacity-of-a-CV(slots) + calculated-management-area-capacity
To convert the resulting entire capacity into megabytes, use the following formula.
Calculated-entire-capacity-of-a-CV(slots) in the following formula means the entire capacity of
a CV if the data protection level is set to the enhanced mode on the SATA drive.
calculated-entire-capacity-of-a-CV(slots) ÷ 1024 x capacity-of-a-slot
•
If the unit for CV capacity is block:
To calculate the entire capacity of a CV, use the following formula. The resulting entire capacity
is expressed in slots.
user-specified-CV-capacity ч 2 ч capacity-of-a-slot
NOTE:
The capacity of a slot is expressed in kilobytes. The capacity of a slot depends on
the volume emulation types (see
).
To calculate the management area capacity, use the following formula:
entire-capacity-of-a-CV(slots) ÷ calculated-management-area-capacity x boundary-value
NOTE:

To calculate the entire capacity of a CV if the data protection level is set to the enhanced
mode on the SATA drive, use the following formula:
entire-capacity-of-a-CV(slots) + calculated-management-area-capacity
To convert the resulting entire capacity into blocks, use the following formula.
Calculated-entire-capacity-of-a-CV(slots) in the following formula means the entire capacity of
a CV if the data protection level is set to the enhanced mode on the SATA drive.
calculated-entire-capacity-of-a-CV(slots) x capacity-of-a-slot x 2
