Double Striping Configuration with Distributed Parity
RAID5+0(2D+1P) ´2 is used in the following examples to explain how to install drives that are con-
figured for double striping with distributed parity.
The drive number is determined by the DE-ID of the enclosure and the slot number in which the
drive is installed. Drives are divided into two redundant set groups in ascending order of drive num-
bers.
