Reducing overlap through shuffle and keeping relationship balance on mapped RAID system and method

机译:通过改组减少重叠并保持映射的RAID系统和方法之间的关系平衡

摘要

A method, computer program product, and computer system for reducing, by a computing device, overlap in a RAID extent group by moving a first disk extent in an extent pool from a source disk to a target disk in a Mapped RAID group. A neighborhood matrix for the Mapped RAID group may be balanced by moving a second disk extent in the extent pool from the source disk to the target disk in the Mapped RAID group.
