HP NetRAID Array Definition
When Disk Administrator calculates disk capacity, it disregards redundancy storage used
by the selected RAID level. Because of this, the displayed and useable storage capacity
for the array is less than the total capacity of all drives in the array. The displayed and
useable array capacity for a RAID 5 array will be C(N-1), where N is the number of
drives and C is the capacity of one drive. Likewise, the RAID 1 displayed and useable
storage will be one-half as large in capacity.
