Abstract: According to an aspect of the embodiment, a packet analyzing apparatus monitors a concentration level of input and output access from an access apparatus to a disk device, specifies a data area to which the concentration level of input and output access exceeds a first threshold, and instructs a storage server to cache the data area. The packet analyzing apparatus monitors a concentration level of input and output access to a data area to which the data area is cached, and, when the concentration level of input and output access is below a second threshold, instructs the storage server to release the caching.

Abstract: A data allocation control program manages data allocation when data is distributively stored in a plurality of disk nodes that are shifted to a power saving mode unless access is performed for a certain time. The program produces a plurality of allocation pattern candidates each indicating the disk nodes in which the respective data are to be stored. The program calculates a no-access period expectation that represents an expected value of occurrence of a no-access period during which access is not performed to some of the disk nodes. The program selects as an allocation pattern for data reallocation, one of the plurality of produced allocation pattern candidates with the largest calculated no-access period expectation. The program instructs the disk nodes to reallocate the respective data in accordance with the selected allocation pattern.
