摘要 |
A method of RAID restriping in a disk drive system (100), comprising: selecting a RAID device for migration from a plurality of RAID devices based on a comparison between an initial score and at least one second score calculated for each of the plurality of RAID devices, wherein: the initial score relates to the RAID device in its present state and is calculated based on one or more scoring factors; and the at least one second score relates to at least one hypothetical RAID device located in available disk space and is calculated based on one or more scoring factors; creating at least one alternate RAID device based on one of the at least one hypothetical RAID device; moving data (408) stored at the selected RAID device to the at least one alternate RAID device; removing the selected RAID device. |
