  • Patent number: 11073997
    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.
