A clustered storage system includes a plurality of nodes and a management server that consolidates physical position information concerning data in each of the nodes. The management server includes a process to relate the information to the configuration of the clustered storage system and the configuration of each node and present such relations. Each node has a process to obtain the size and load of resources that are used in processing. The management server has a process to collect and tally such resource usage status from each node, and a process to relate the resource usage status, the data information and configuration information to each other and present the relations in a hierarchy. The clustered storage system has a process to move logical volumes among nodes in a manner transparent to the host computer. The management server has a process to support the selection of source data and destination physical position through information display, and a process to receive instruction for such move and to direct the clustered storage system of such move.
