ABSTRACT:
A method and system are provided for implementing a redundant array of independent devices (“RAID”) having disparate SCSI configurations and capabilities. A portion of the memory of each SCSI device of the RAID set is reserved for RAID configuration information. In one embodiment, a SCSI RAID controller is provided with a protocol for accessing user information and RAID configuration information on the SCSI devices. By reserving RAID configuration information at a common place on each SCSI device, control and configuration of the RAID array is simplified and unified. Unified configuration of the RAID members enables utilization of devices from disparate manufacturers.
