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, on the basis of the load information on the volumes acquired by the monitoring unit, an entire bandwidth of the Tier pool. A bandwidth management unit calculates, on the basis of the minimum guarantee bandwidth for each of the predetermined volumes, each of individual bandwidths such that the sum total of the individual bandwidths allocated to the respective volumes corresponds to the entire bandwidth calculated by the maximum performance calculating unit 101 and allocates the calculated individual bandwidths to the respective volumes.

主权项

1. A storage management device comprising:
a load information acquiring unit that acquires load information on a storage area group that includes therein a plurality of storage areas; a calculating unit that calculates, on the basis of the load information on the storage area group acquired by the load information acquiring unit, an entire bandwidth of the storage area group; and an allocating unit that calculates, on the basis of a minimum guarantee bandwidth for each of the predetermined storage areas, each of individual bandwidths such that the sum total of the individual bandwidths allocated to the respective storage areas corresponds to the entire bandwidth calculated by the calculating unit and allocates the calculated individual bandwidths to the respective storage areas.
