Title:
ディスクアレイシステム
Document Type and Number:
Japanese Patent JP5353030
Kind Code:
B2
Abstract:
A disk array system comprises plural disk array devices, and each disk array device has two disk array controllers (first DAC and second DAC) for controlling a disk array. In each disk array device, the first DAC has a redundant configuration with a second DAC of any one of the other disk array devices. Likewise, in each disk array device, the second DAC has a redundant configuration with a first DAC of any one of the other disk array devices. Accordingly, because of the failure of a backboard or the like, even if the first DAC and second DAC of a disk array device become inoperative, when their partners in the redundant configurations are operative, the function as the DAC is maintained. Therefore, it is possible to replace a disk array device or the backboard thereof without terminating the operation of the disk array system.
