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： 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.

摘要： Time required for a file server to determine files to be migrated from a first storage region to a second storage region is reduced. A file service system coupled to the storage system for providing a first storage region and a second storage region stores identifiers of files that have been accessed by a client, in accessed file identifier information and determines the files to be migrated from the first storage region to the second storage region based on metadata of the files stored in the first storage region and the accessed file identifier information.

摘要： There is provided a file management method of a hierarchy management file system capable of preventing an access performance from dropping when a user accesses to a file. According to the 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 to copy the file, so that the accessing performance may be prevented from dropping.
摘要翻译： 提供了一种层次管理文件系统的文件管理方法，其能够防止访问性能在用户访问文件时丢弃。 根据该方法，服务器以高速和低速卷创建文件系统，并且文件共享服务器将这些文件系统虚拟地整合为一个系统作为伪文件系统。 然后，服务器将要移动的文件移动到提前在低速卷中创建的文件系统，而不是对文件进行访问。 当用户在此之后访问该文件时，用户直接访问目的地而不需要复制文件，从而可以防止访问性能下降。
