Abstract: In a file server for suppressing power consumption of a storage apparatus, when a file sharing program receives a file access from a client, the program references a mapping table. The program addresses the access to the target file in the volume of a RAID group where the target file is stored. A coupling-request reception program memorizes a coupling time for each user into a coupling history table. A grouping program applies a grouping to users whose coupling time-zones are similar. A data transfer program transfers, into the same RAID group, data of the files associated with the grouped users, thereby collecting the data into the same RAID group. Thus, the time-zone when no access is made to the RAID group (i.e., non-coupling time-zone) can be made longer. Accordingly, a spin-up/down request program makes a spin-down request to the RAID group in the non-coupling time-zone.

Abstract: There is provided a file management system and method of creating a hierarchy management file capable of preventing an access performance from dropping when a user accesses to a file. According to the system and method, a server creates file systems in high-speed and low-speed volumes and a file-sharing server virtually integrates those file systems into one system as a pseudo file system. Then, the server moves a file to be moved to the file system created in the low-speed volume in advance, not when an access is made to the file. When a user accesses to the file after that, the user directly accesses to destination without requiring tcopying the file, so that the accessing performance may be prevented from dropping.

A radiating member includes plate-shaped radiating fins vertically placed in the light chamber, for radiating heat energy generated by the light source to surrounding air. A plate is arranged at a right angle to the radiating fins in the light chamber, for controlling air-convection flow around the radiating fins.

Abstract: When a management screen for conducting management operation of a file system in the NAS apparatus 10 of a file server is displayed by the administrator on a display device of the management console 30 by using the management console 30, if a disk device obtained from the storage apparatus 20 is in a power saving state, the NAS apparatus 10 has a function to change the operations hereafter. Specifically, a screen is displayed on the management screen, in which a creation or deletion of the file system becomes impossible with respect to the disk device in the power saving state. Therefore, the administrator can conduct management operations for services without referring to the power status, thereby resulting in easy management operation.

Abstract: 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.

Abstract: A file management sub-system executes file migration without causing an unintended drop in the response time or the like. When a management computer issues a file migration direction, a file storage apparatus notifies client computer associated with a migration target file that file migration is scheduled. When postponement or suspension of file migration is requested by the client computer, the file migration is postponed or suspended.

Abstract: The storage system eliminates inconsistency between a stub, and a file data storage location indicated by the stub. In a storage system that executes HSM using stubs, information relating to a higher tier, which is a data migration source, is recorded during data migration. The stub in the higher tier is correctly restored using the higher-tier information thus recorded. The stub is restored, and inconsistency between information in the HSM layers is resolved.
