STORAGE MANAGEMENT DEVICE, STORAGE MANAGEMENT METHOD, AND COMPUTER-READABLE RECORDING MEDIUM

摘要

A monitoring unit acquires load information on a Tier pool that includes therein a plurality of volumes. A maximum performance calculating unit calculates an entire bandwidth of the Tier pool on the basis of the load information on the Tier pool acquired by the monitoring unit. A bandwidth management unit calculates each individual bandwidth such that the sum of the individual bandwidths allocated to each of the volumes corresponds to the entire bandwidth calculated by the maximum performance calculating unit and allocates each of the calculated individual bandwidths to each of the volumes.

1. A storage management device comprising:
a memory; and a controller that acquires load information on a storage area group that includes a plurality of storage areas, stores the load information in the memory,
calculates an entire bandwidth of the storage area group on the basis of the acquired load information on the storage area group, andcalculates each individual bandwidth such that the sum of the individual bandwidths allocated to each of the storage areas corresponds to the entire bandwidth calculated and that allocates each of the individual bandwidths to each of the storage areas.
