REDUCTION OF MAXIMUM LATENCY USING DYNAMIC SELF-TUNING FOR REDUNDANT ARRAY OF INDEPENDENT DISKS

摘要

Memory systems may include a redundant array of inexpensive disks (RAID) group including a plurality of disks, and a storage access layer including a RAID engine suitable for requesting data from the RAID group, determining whether a disk in the plurality of disks is busy based on a latency threshold, when the disk is determined to be busy, determining whether the requested data can be obtained from other non-busy disks in the plurality of disks, and obtaining the requested data when the data is determined to be obtainable from the other non-busy disks.
