Storage management apparatus and storage management method |
摘要 |
A reference-capacity calculating unit calculates a reference capacity of each of storage devices storing therein data on the basis of an actual capacity of each storage device. A difference calculating unit calculates a difference value between the reference capacity calculated by the reference-capacity calculating unit and the actual capacity of each storage device. A maximum-value retrieving unit retrieves the maximum difference value out of the respective difference values of the storage devices calculated by the difference calculating unit. A defined-capacity determining unit determines a defined capacity, which is an actually-used capacity of each storage device, on the basis of a value obtained by subtracting the maximum difference value from the reference capacity calculated by the reference-capacity calculating unit. |
