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 configured 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 numbers.
Example 4: Drives are installed in two different drive enclosures
