RAID system pack sizing
The RAID system limits the actual capacity of any system pack to the size
of the smallest drive in its pack. As drives are replaced, a mirrored set may
consist of two drives of different sizes, possibly from different
manufacturers. To support the replacement of a failed disk drive with that of
another manufacturer, an engineering restriction specifies the size of the
system pack.
To continue configuring the RAID system, calculate the drive size as
follows:
2 x smallest drive in the pack
For example, if System Pack A has a nominal capacity of 4 Gbytes (2 x 2
Gbytes), enter a system drive size of 4096. Since RAID Level 1 (mirroring)
is used, the resulting capacity is half of what you calculated.
The following tables specify the system pack sizes to enter when you
configure RAID systems. These sizes apply for currently qualified disk
drives and may change in the future.
