ABSTRACT:
Disclosed is an adaptive maximum request size process to change the maximum request size for a RAID system in order to reflect the highest possible maximum request size permitted by the RAID type and the physical drives included in the RAID system. The maximum request size is a primary limiting characteristic for physical drive and logical drive performance. The logical drive maximum request size is limited by the physical drive maximum request size. Physical drives supporting older revisions of the physical drive standards have a much lower maximum request size than physical drives supporting newer revisions of the physical drive standard. The adaptive maximum request size process permits a RAID system to adjust the maximum request size to reflect the highest possible maximum request size allowed for a given system based on the physical drives of the RAID system and the RAID types of all RAID logical drives. The adaptive maximum request size process also permits a RAID system to mix physical drives from older and newer generations while still achieving the highest possible maximum request size for the RAID system.
