摘要：A monitoring unit obtains the performance information of each of a plurality ofvolumes included in a storage device. A setting unit obtains a performance target valuefor each of one or more targeted volumes from among the plurality of volumes. Basedon the performance information obtained by the monitoring unit and based on a first-type standby time that is attributed to bandwidth limitation of IO requests with respectto the targeted volumes which are obtained by the setting unit and which achieve theperformance target value, a bandwidth managing unit obtains the bandwidth for thetargeted volumes that achieve the performance target value and performs bandwidthlimitation to change the bandwidth of the targeted volumes to the obtained bandwidth.
