摘要： When receiving a file access from the client, the file access program refers to the mapping table, and processes an access to files of on volumes of RAID groups. The file server analyzes the file access states, and groups the files depending on the access time period, defines the file migration pattern based on the grouping, migrates the files, and then carries out a power management operation like a spin-down/-up operation on the RAID groups based on the migration pattern.

摘要： The present invention enhances user usability by storing more files close to the user. A replication processing part 3A creates a replica of a prescribed file, which is in a first file management apparatus, in a second file management apparatus. A single instance processing part 3B selects as a duplicate data removal target another prescribed file in the first file management apparatus in accordance with a first prescribed condition, and converts the selected other prescribed file to a reference-source file, which references data of a prescribed reference file. A stubification processing part 3C selects a stubification candidate file, which constitutes a target of a stubification process, in accordance with a second prescribed condition, and executes stubification processing with respect to the stubification candidate file in accordance with a third prescribed condition.
