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).
摘要翻译：每个存储设备1,2相对于传输路径A和B中的每一个设置有传输队列306a，306b。存储设备1在每个传输队列306a和306b中存储相同的请求数据，以及分别经由传输路径A和B将每个数据发送到对方存储设备2（S 811,812）。作为对方的存储装置2存储先前在接收历史信息表300中到达的请求数据或响应数据（S 817），并丢弃稍后到达的请求数据（S903,904）。此外，作为发送源的存储装置1如果接收到针对请求数据的至少一个响应数据，则存储装置1在发送队列306a，306b中进行搜索，如果在发送队列中存在请求数据删除请求数据（S909）。

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： In the process of controlling a plurality of storage devices 190 in any one of a normal mode and a plurality of power-saving modes (such as standby and LRPM), a controller 110 selects the storage devices whose mode should be shifted from the normal mode to any of the power-saving modes; and before shifting to control of the selected storage devices in any of the power-saving modes, the controller calculates time and electric power required to make the selected storage devices return from each power-saving mode to the normal mode; and based on each calculated value, the controller sets a combination of power-saving modes and the number of storage devices that satisfy the return conditions defined by the host timeout period and the supplied power; and then, the controller controls the selected number of storage devices in the set combination of power-saving modes.

摘要： The invention is directed to a load sharing method in a computer system including a first storage subsystem, a host computer, and a management computer. In the computer system, the first storage subsystem creates a plurality of first logical units from a storage area of a disk drive group, and the host computer creates a logical storage area configured by a plurality of virtual logical units respectively corresponding to the first logical units. A communications path is set between the host computer and each of the first logical units configuring the logical storage area. The load sharing method includes the steps of: monitoring, by the first storage subsystem, a load of its own; and changing, by the first storage subsystem, the communications paths between the host computer and the first logical units based on the monitoring result of the load. With such a configuration, provided is a computer system high in extensibility not deteriorating the performance at the limit of the system after load sharing among the storage subsystems.
