Abstract: When the application I/O performance problem is solved, the I/O amount from the application is increased. In the conventional technique, no consideration has been taken on the affect of the increase of the application I/O performance to other applications. A resource whose I/O load is reduced by setting modification of a storage subsystem is specified and the application using this resource is specified as an application whose I/O processing amount may be increased. Furthermore, the resource used by the specified application and another application using this resource are specified as a resource and an application whose I/O processing performance may be lowered by the setting modification.

Abstract: A method for rearranging a logical volume including arranging a logical volume rearranging program on a particular server and using the logical volume rearranging program to acquire server/storage mapping information from each server and performance information from each storage subsystem. Moreover, the logical volume rearranging program acquires request I/O performance and a rearranging rule for each application set by a user. Furthermore, the logical volume rearranging program determines a destination by using the logical volume rearranging destination parity group specified by the user according to the aforementioned information, and rearranges the logical volume according to the storage subsystem performance and the request I/O performance of each application.

Abstract: Provided are an area management table, an operation management policy, and a resource broker. In the area management table, one or more physical area IDs for identifying one or more storage area candidates selected from a plurality of physical storage areas, are associated with each application program. The operation management policy states a guideline for storage area assignments based on operational status of each server provided with the application programs. The resource broker detects the operational status of each server, and based on the detected operational statuses and the operation management policy, determines physical storage areas to assign to each application program.

Abstract: A CPU of a performance management server, upon receipt of a request from a keyboard or a mouse to newly assign an application to a specified application server, acquires an I/O path between the requested application server and a storage subsystem combined with the application server from the configuration information managed by the internal database of the performance management server, and based on the performance information managed by the database in the performance management server, an I/O path having the performance information satisfying the designated conditions is extracted from the acquired I/O paths and displayed as a candidate path on a display unit.
