ABSTRACT:
Each of the storage devices1, 2is provided with transmission queues306a, 306bwith respect to each of transmission paths A and B. The storage device1stores identical request data in each of the transmission queues306aand306b, and transmits each data to the counterpart storage device2, respectively via the transmission path A and B (S811, 812). The storage device2, being a counterpart, stores the request data or response data arrived earlier in the receive history information table300(S817), and discards the request data arrived later (S903, 904). Furthermore, if the storage device1, being a transmission source, receives at least one response data against the request data, the storage device1searches the transmission queues306a, 306b, and if there remains request data in any of the transmission queue, deletes the request data (S909).
