PROBLEM TO BE SOLVED: To provide a storage management device, performance adjustment method, and performance adjustment program that make a system operate stably while adjusting the band width.SOLUTION: A guaranteed value setting unit 101 stores a guaranteed value of the performance of transmitting/receiving data from a predetermined volume 232 in a plurality of volumes 232 included in a storage device 2. A band width management unit 102 calculates a provisional target value on the basis of a comparison result between the guaranteed value and a measured value of the performance of transmitting/receiving data from the predetermined volume 232, assigns a band width for compensating the difference between the guaranteed value and the measured value to a predetermined storage region on the basis of the provisional target value, determines band width distribution to each of the plurality of volumes 232, and commands the storage device 2 to adjust the band width using the determined band width distribution.SELECTED DRAWING: Figure 3 |
