DISK STORAGE DEVICE AND RAID CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a disk storage device capable of easily constructing a RAID system simply constructed as a whole by combining a plurality of disk drives without using any special device such as a RAID controller. SOLUTION: This disk storage device functions as a disk drive by itself and incorporates a RAID construction function for constructing RAID in collaboration with other disk drives. The disk storage device has a communication means for exchanging information about the RAID function with other disk drives and constructs the RAID system in collaboration with the other disk drives in response to a command from a host system.
