PROBLEM TO BE SOLVED: To provide a storage management device that properly changes a distribution ratio of disks in performance adjustment in automatic hierarchization of a storage, a performance adjustment method, and a performance adjustment program.SOLUTION: A receiving part 111 receives input of designation of performance level to a volume 232 that is allocated by using a different types of disks. A target value calculation part 112 determines a target value of performance in transmission/reception of data to the volume 232 on the basis of a predetermined distribution radio for each of the types of the disks. A performance management part 102 determines the distribution ratio for each of the types of the disks included in the volume 232 on the basis of the target value calculated by the target value calculation part 112, determines a distribution of bands to the volume 232, and instructs, to a storage device 2, re-allocation of the volume 232 with the determined distribution ratio and adjustment of the band width with the determined band distribution.SELECTED DRAWING: Figure 3 |
