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.
