According to the conventional art disk array system, when a drive box of a first chassis is blocked, all the drive boxes of a second chassis connected subsequently therefrom will be blocked, and the data in the drive boxes arranged subsequently therefrom cannot be recovered based on the RAID configuration. Even if the data could be recovered based on RAID configuration, it is necessary to perform the recovery process based on RAID in all the subsequently arranged drive boxes, according to which the performance is deteriorated. The present system stores a first drive box in a first chassis out of a plurality of chassis, and a second drive box and a third drive box are stored in a second chassis. One of a plurality of expander controllers within the first drive box is connected to an expander controller in the second drive box, and the other expander controller is connected to an expander controller in the third drive box. |
