Abstract: Provided is a storage system and a data management method of a storage system enabling system-wide data deduplication. The storage system has a plurality of storage apparatuses in which one or a plurality of logical volumes are provided. Based on data information of data obtained through the generation of a request to write to a logical volume in the storage system, one storage apparatus among the plurality of storage apparatuses calculates, for a plurality of combinations of storage apparatus and logical volume in the storage system, a data capacity when duplicate data is removed for each of the storage apparatuses, calculates the total of the calculated data capacities as the total capacity of the whole storage system, and performs optimal arrangement arithmetic processing to output information indicating a combination with the smallest total capacity among the plurality of combinations.

Abstract: A method for performing a system reconfiguration of a storage system includes displaying a configuration window visually showing a configuration of a plurality of components in the storage system within an operation screen. An input area is displayed within the operation screen, the input area being provided for entering one or more components to be reconfigured. A performance window is displayed within the operation screen, the preference window providing bandwidth utilization information of one or more of the components in the storage system. The configuration window, performance window, and the input area are all viewable at the same time without activating another operation screen.
