Note 1: D: Data disk, P: Parity disk
Note 2: Although the subsystem with a configuration of RAID6, RAID 5, RAID 1, or RAID 1+0
provides data reliability enhanced by means of redundancy, a possibility remains that user
data is lost owing to an unexpected failure of a host computer or hardware/software of the
subsystem itself. Therefore, users are requested to back up all data for restoration in case
where the original data is lost.
RAID 0+1 is described in place of RAID 1+0 in some places, however, it has the same meaning
as RAID 1+0.
