An operation management server that manages a storage apparatus in which volumes are included and data is sent and received via transmission resources is provided. The operation management server includes a setting unit that sets a target value of the performance to some or all of the volumes; a monitoring unit that monitors the load factor of the transmission resources; and a bandwidth management unit that specifies a target transmission resource on the basis of the load factor of the transmission resources, that decides, on the basis of the target value, bandwidth allocation of some of the volumes that use the specified transmission resource, and that instructs a bandwidth control unit in the storage apparatus to adjust the bandwidth on the basis of the decided bandwidth allocation.

Storage management device and control method

A reception unit receives an input of designation of a performance level for a volume. A target value calculation unit obtains a target value of performance of data transmission and reception with respect to the volume according to the input performance level. A setting unit sets the target value obtained by the target value calculation unit for the volume. A monitoring unit monitors a load factor of a transmission resource. A bandwidth management unit identifies a target transmission resource based on the load factor of the transmission resource, decides a bandwidth allocation to a memory unit that uses the target transmission resource based on the target value, and instructs a bandwidth control unit of a storage device to tune the bandwidth using the decided bandwidth allocation.
