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.

摘要： Upon detection of a virus definition file update, a virus check server mounts a computer's storage area in a storage apparatus via a network to check whether or not a file stored in the storage area is infected with a virus. For the virus check, the virus check server communicates with the storage apparatus via a path different from the one that is laid between a user computer and the storage system. Therefore, a virus check executed by the virus check server does not lower the computer's communication speed and disk access speed.
摘要翻译：在检测到病毒定义文件更新时，病毒检查服务器经由网络将计算机的存储区域安装在存储装置中，以检查存储在存储区域中的文件是否被病毒感染。对于病毒检查，病毒检查服务器通过与用户计算机和存储系统之间的路径不同的路径与存储设备进行通信。因此，病毒检查服务器执行的病毒检查不会降低计算机的通信速度和磁盘访问速度。

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).
