| Abstract | To provide a storage system and a data management method for a storage system, which allow duplication of data to be excluded in an entire system.SOLUTION: In the storage system provided with a plurality of storage devices each of which is provided with one or a plurality of logical volumes, one storage device out of the plurality of storage devices is configured to perform optimal arrangement operation processing of: calculating, with respect to each of the storage devices in a plurality of combinations between the storage devices and logical volumes in the storage system, a data capacity resulting of excluding duplication of data on the basis of data information of data requested to be written into the logical volumes in the storage system; calculating sum totals of calculated data capacities as total capacities in the entire storage system; and outputting information indicative of a combination giving the smallest total capacity out of the plurality of combinations.SELECTED DRAWING: Figure 2
【課題】システム全体としてデータの重複排除が可能なストレージシステムおよびストレージシステムのデータ管理方法を提供する。【解決手段】一または複数の論理ボリュームが設けられるストレージ装置を複数備えるストレージシステムであって、複数のストレージ装置のうちの一のストレージ装置は、ストレージシステムにおける論理ボリュームに対して書込要求が発生したデータのデータ情報に基づいて、ストレージシステムにおけるストレージ装置と論理ボリュームとの複数の組合せについて、ストレージ装置ごとに、重複したデータを排除したときのデータ容量を算出し、算出したデータ容量の合計をストレージシステム全体としての総容量として計算し、複数の組合せのうちで最も総容量が小さい組合せを示す情報を出力する最適配置演算処理を行うようにした。【選択図】図２ |
