Abstract
A data arrangement apparatus calculates evaluation values for individual relocation processes generated based on an access pattern. Each of the relocation processes indicates a relocation of some of a plurality of unit data pieces in a storage device. The data arrangement apparatus selects, amongst influence range levels whose ranges in relation to unit data pieces to be affected by the relocation differ in extent of influence, one influence range level based on the evaluation values and coefficients associated one-to-one with the influence range levels. Based on the extent of influence indicated by the selected influence range level, the data arrangement apparatus determines one or more relocation processes to be executed amongst the generated relocation processes. Based on access status after the determined relocation processes are executed, the data arrangement apparatus updates a coefficient associated with the selected influence range level.
