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： A storage controller comprises a cache storage used as a cache of an external storage and a control processor coupled to the cache storage. The control processor comprises an internal access function and an external access function. The internal access function transmits a read command to the cache storage. The cache storage determines whether the read target data complying with the read command is stored in a physical storage device or not. If the result of the determination is negative, the external access function is executed while, if the result of the determination is positive, the external access function is not executed because the cache storage transmits the read target data to the internal access function without issuing a request to the external access function.
摘要翻译：存储控制器包括用作外部存储器的高速缓存的高速缓存存储器和耦合到高速缓冲存储器的控制处理器。控制处理器包括内部访问功能和外部访问功能。内部访问功能将读取命令发送到缓存存储。高速缓冲存储器确定符合读取命令的读取目标数据是否存储在物理存储设备中。如果确定结果为否定，则执行外部访问功能，如果确定结果为肯定，则不执行外部访问功能，因为高速缓存存储器将读取的目标数据发送到内部访问功能而不发出请求外部访问功能。

摘要： A plurality of CPU cores each have control rights for logical storage areas of one or more types among logical storage areas of a plurality of types. As a source for an area to be assigned to the logical storage areas, a physical storage area which is common to the logical storage areas of the plurality of types is managed. Each CPU core, in the case of a data access to a logical storage area corresponding to the control rights of the CPU core, assigns an area required to store the data from the common physical storage area.

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.

摘要： The usage of communication systems is improved. An IM server 4 manages presence information regarding each of IM clients and usable media and user information such that each of the IM clients can obtain these kinds of information. In order to perform text chatting, the IM server 4 manages a connection between each of the IM clients participating the chat and the IM server 4, merges text from each of the participating IM clients and distributes the result to each of the participating IM clients. In order to perform voice chatting, an AP server 5 manages a connection between each of the IM clients participating the chat and an MD server 6, mixes voice from each of the participating IM clients except for a focused IM client and distributes the result to the focused participating IM clients. This processing is performed for each of the participating IM clients.
