Abstract

A queuing architecture within a RAID controller that manages a multi-threaded SCSI environment. The architecture resides within a RAID controller that communicates with a plurality of independent, SCSI disk drives (or other storage elements). The RAID controller accepts disk I/O requests from one or more host computers. The architecture dynamically allocates multiple disk I/O requests to various request queues until the disk drive that will handle the request is available for access. Multiple requests are executed in parallel on various ones of the disk drives.
