ABSTRACT:
A disk array system where a plurality of SATA drive enclosures are connected through an FC loop is made capable of continuing to process data even in the event of a fault. When the system is normally operated, a first system controller and a second system controller execute read/write operations from and to disks of a SATA drive enclosure of a disk array via a first interface connector and a second interface connector, respectively, through the FC loop. When an error occurs on a second backend FC loop, the second system controller disconnects itself from the failed second backend FC loop and switches the path to a first backend FC loop which is normally functioning, to access the disk drive.
