摘要： There is provided a file server which is capable of suppressing power consumption of a storage apparatus. When a file sharing program receives a file access from a client, the program makes reference to a mapping table. Then, the program addresses the access to the target file in the volume of a RAID group in which 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 to each other. A data transfer program transfers, into the same RAID group, data of the files associated with the grouped users, thereby collecting the data of the files into the same RAID group. On account of this, the time-zone during which 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.
摘要翻译：提供了能够抑制存储装置的电力消耗的文件服务器。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。然后，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彼此相似的用户。数据传输程序将与分组用户相关联的文件的数据传送到相同的RAID组中，从而将文件的数据收集到相同的RAID组中。因此，可以使不对RAID组进行访问的时段（即非耦合时间段）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。

摘要： A computer apparatus which integrates at least two or more services of user management domains has a processor, a memory and an interface. The processor receives an access request, specifies an access source domain, specifies an access target domain, and judges whether the specified access source domain matches the specified access target domain. If the access source domain is different from the access target domain, the processor extracts a user ID of the specified access source domain from the received access request, and refers to ID conversion information indicating correspondence of user IDs between the user management domains whose services are integrated to convert the extracted user ID of the access source domain into a user ID of the specified access target domain. Thus, loads of configuration at the time of service integration are reduced.
摘要翻译：集成用户管理域的至少两个或多个服务的计算机装置具有处理器，存储器和接口。处理器接收访问请求，指定访问源域，指定访问目标域，并判断指定的访问源域是否与指定的访问目标域匹配。如果访问源域不同于接入目标域，则处理器从接收的访问请求中提取指定的访问源域的用户ID，并且引用指示用户ID在用户管理域之间的对应关系的ID转换信息，集成以将提取的访问源域的用户ID转换为指定的访问目标域的用户ID。因此，降低了服务集成时的配置负载。

摘要： When any file sharing server among a plurality of file sharing servers configuring a virtual file system receives a backup requests from a backup server, the file sharing server that received the backup request searches a file sharing server managing the files to be backed up among the plurality of file sharing servers, and transfers the backup request to the searched file sharing server. The file sharing server that received the transfer of the backup request transfers the backup data to the media server via a connection server.

摘要： A data intermediate server 300 comprises the functions of reading data stored in storage servers ST1 through ST3 and sending the data to a media server 600 according to backup commands received from a backup control device 400 over a local area network LAN4. The data intermediate server 300 and the storage servers ST1 through ST3 are connected by channels that do not permit Internet protocol traffic but only data targeted for backup and control data assigned thereto. As a result, client data stored on the storage servers can be properly backed up while preventing data from being improperly retrieved or leaked.
摘要翻译：数据中间服务器300包括读取存储在存储服务器ST1至ST3中的数据的功能，并且根据从备用控制设备400通过局域网LAN 4接收的备份命令将数据发送到媒体服务器600.数据中间服务器300和存储服务器ST1至ST3通过不允许因特网协议流量的信道连接，而仅通过分配给备份和控制数据的数据来连接。因此，可以正确地备份存储在存储服务器上的客户端数据，同时防止数据被不正确地检索或泄漏。

摘要： Regarding a method for migrating a file system by copying a file from a migration source to a migration destination and deleting the file at the migration source, a retention of a file in a page (allocation unit of a thin provisioning function) is either suppressed or solved, and two methods are proposed for solving the problems and for enabling migration of a file system in which the increase of utilization of storage capacity is suppressed, wherein one method changes the location of a file prior to performing copying so that the file to be copied next is located in the same page, and another method creates a reverse index table to recognize which block is used by files, thereby enabling to specify the file remaining within a page and copy the same by referring to this reverse index table.

摘要： A method and a storage system are provided for implementing a sustained large block random write performance mechanism for shingled magnetic recording (SMR) drives in a redundant array of inexpensive disks (RAID). A Solid State Drive (SSD) is provided with the SMR drives in the RAID. The SSD is used in a hot spare mode, which is activated when a large block random-write event is identified for a SMR drive in the RAID. In the hot spare mode, the SSD temporarily receives new incoming writes for the identified SMR drive. Then the identified SMR drive is updated from the SSD to restore the state of the identified SMR drive, and operations continue with normal writing only using the SMR drives in the RAID.

摘要： In order to provide HSM that can effectively use the storage capacity of an upper Tier in an HSM system, a lower Tier of the HSM system detects a group of files having the same data content from a plurality of files stored in the lower Tier, and keeps at least one of the real data of the group of files having the same data content while deleting the rest of the data. The upper Tier receives the process result from the lower Tier. Then, in response to a read request from the host computer that specifies a file included in the group of files and transferred to the upper Tier from the lower Tier, the upper Tier identifies the at least one of the data that is kept and corresponding to the specified file, and responds to the host computer.
