    • 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.
    • 在用于抑制存储装置的功耗的文件服务器中,当文件共享程序从客户端接收文件访问时,程序引用映射表。 该程序解决存储目标文件的RAID组的卷中对目标文件的访问。 耦合请求接收程序将每个用户的耦合时间记录到耦合历史表中。 分组程序将分组应用于其耦合时区相似的用户。 数据传输程序将与分组用户相关联的文件的数据传输到相同的RAID组中,从而将数据收集到相同的RAID组中。 因此,可以使不对RAID组进行访问的时区(即非耦合时区)更长。 因此,启动/关闭请求程序在非耦合时区中向RAID组发出旋转下降请求。

    • The client computer which transmits an access request specifying an object existing in the first file system and the second computer which accesses the second file system are connected to the first computer which accesses the first file system. The second file system includes a shared directory. A specific object which is an object complying with the path name including the name determined in accordance with the type of the second computer is stored in the shared directory. The controller mounts the shared directory to the first file system. The controller creates a link which comprises a name determined in accordance with a certain naming regulation independent of the type of the computer and corresponds to the specific object in the first file system.

    • An information processing system retains one or more files utilized by an external apparatus, each of which is made up of a plurality of chunks, in a manner that the chunks making up each of the files are distributed. The information processing system includes a plurality of chunk servers, each storing chunks, and one master server communicatively coupled thereto. The master server retains a file name of a file, chunk IDs indicating chunks making up the file, and chunk IDs indicating chunk servers storing the chunks. When a snapshot taking request for a file is received, the master server identifies chunks included in the file from the file name and the chunk IDs to instruct the chunk servers having these chunks to take a differential snapshot of each of the chunks with the use of a differential snapshot function included in a local file system of each of the chunk servers.
