Summary:PROBLEM TO BE SOLVED: To calculate access performance of a storage device, in accordance with a state of use of the storage device.SOLUTION: In measuring a load state of a storage device 102, a storage control apparatus 101 calculates a rate of accesses to each of blocks with respect to accesses to a storage area of the storage device 102. The storage control apparatus 101 calculates access performance of the storage device 102, on the basis of the access rates of the blocks and information 111 indicating measured access performance of the blocks. The storage control apparatus 101 accurately estimates access performance of the storage device 102, in accordance with a state of use of the storage device 102.SELECTED DRAWING: Figure 1 【課題】ストレージ装置の使用状況に応じたストレージ装置のアクセス性能を算出すること。【解決手段】ストレージ装置１０２の負荷状態を測定する際、ストレージ制御装置１０１は、ストレージ装置１０２の記憶領域のアクセス数に対する各ブロックのアクセス数の割合を算出する。そして、ストレージ制御装置１０１は、各ブロックのアクセス率と、測定した各ブロックのアクセス性能を示す情報１１１とに基づいて、ストレージ装置１０２のアクセス性能を算出する。これにより、ストレージ制御装置１０１は、ストレージ装置１０２の使用状況に応じたストレージ装置１０２のアクセス性能を正確に推定することができる。【選択図】図１
