摘要： A storage device (1) communicating with a host computer and other storage devices through a network is characterized in that the storage device (1) secures memory buffers for temporarily storing data in a remote copy operation carried out between the storage devices. A network memory (100) in the storage device (1) includes an available buffer comprising a plurality of memory buffers and an in-use buffer also comprising a plurality of memory buffers. A buffer control unit (215) secures memory buffers of the available buffer as a reserved buffer having a reserved-buffer size specified in a buffer reservation request made by a storage management device (8) in response to the request. The buffer control unit (215) then allocates the memory buffers of the reserved buffer as the in-use buffer in response to a request received from the storage management device (8) to start a remote copy operation.

摘要： Each of the storage devices 1, 2 is provided with transmission queues 306a, 306b with respect to each of transmission paths A and B. The storage device 1 stores identical request data in each of the transmission queues 306a and 306b, and transmits each data to the counterpart storage device 2, respectively via the transmission path A and B (S811, 812). The storage device 2, being a counterpart, stores the request data or response data arrived earlier in the receive history information table 300 (S817), and discards the request data arrived later (S903, 904). Furthermore, if the storage device 1, being a transmission source, receives at least one response data against the request data, the storage device 1 searches the transmission queues 306a, 306b, and if there remains request data in any of the transmission queue, deletes the request data (S909).

摘要： A storage system includes a first storage node and a second storage node. The first storage node has a first logical unit to which a first target is set, and the second storage node has a second logical unit.To migrate data from the first logical unit to the second logical unit, the first storage node forwards data stored in the first logical unit to the second storage node, and the second storage node stores the data into the second logical unit. The first storage node also forwards information about the first target to the second storage node, and the second storage node sets a target to the second logical unit using the received information.
