RAID specifications
D: Data drive, P: Parity drive.
Although the storage system with a configuration of RAID 1, RAID 5, or RAID
6 provides data reliability enhanced by redundancy, there is a chance that
user data could be lost due to an unexpected host, storage system hardware,
or software failure. Therefore, users are requested to back up all data.
