  • Patent number: 9798471
    Abstract: Embodiments of the present invention relate to a method and apparatus for improving performance of a de-clustered disk array by making statistics on a number and types of active input/output (I/O) requests of each of the plurality of physical disks; dividing the plurality of physical disks at least into a first schedule group and a second schedule group based on the statistic number and types of the active I/O requests of the each physical disk for a predetermined time period, the first schedule group having a first schedule priority, the second schedule group having a second schedule priority higher than the first schedule priority; and selecting, in a decreasing order of the schedule priority, a physical disk for schedule from one of the resulting schedule groups thereby preventing too many I/O requests from concentrating on some physical disks and thereby improve overall performance of a de-clustered RAID.
