Abstract:
A disk array apparatus has a plurality of disks constituting a mounted RAID group and controls access from an upper-level device to each of the disks. The disk array apparatus also has a performance information collector for collecting a piece of performance-related information of each of the disks, and a suspected disk detector for comparing the pieces of information collected for the disks by the performance information collector among disks constituting a single one of the RAID group and detecting a suspected disk suspected of being abnormal in performance based on a result of the comparison.
