Abstract
Data movement for reducing an environmental load in a hierarchical storage is appropriately determined. A storage system includes an upper-level storage device and a management device. The management device is configured to determine, for each file stored in the upper-level storage device, based on a size of a target file and an access frequency of the target file, and the power consumption information, whether power consumption for holding the target file is to be reduced by moving the target file to the lower-level storage device, and output, when it is determined that the power consumption for holding the target file is to be reduced by moving the target file to the lower-level storage device, an instruction to move the target file from the upper-level storage device to the lower-level storage device.
