摘要： When a command received from a client CL is transferred to another server device 100, a server device 100 transfers only the control data part in the command, and exchanges the user data part via a shared memory 200. Because of this, the size of the data that is directly transferred between the server devices 100 is reduced, so it is possible to inhibit delay of responses to the client and to attempt improvement in the performance of the overall storage system. As a result, the processing capability of a storage system having a plurality of server devices is improved.

摘要翻译： 当从客户端CL接收的命令被转移到另一个服务器设备100时，服务器设备100仅传输命令中的控制数据部分，并经由共享存储器200交换用户数据部分。因此， 在服务器设备100之间直接传送的数据被减少，因此可以抑制对客户端的响应的延迟并且尝试改进整个存储系统的性能。 结果，提高了具有多个服务器装置的存储系统的处理能力。

摘要： When CPU 11 receives a request to write to a file stored in a storage device 10 from client computers 30 through 32, it references the object control table of the subject file, and confirms the WORM attribute of the subject file. The CPU 11 references the WORM range control table, and determines whether or not the write subject range is set to a WORM range. When the write subject range is not set to a WORM range, the CPU 11 executes write to the subject file. When WORM form is set for write data, the CPU 11 updates the WORM range control table and sets WORM form for the written data.

摘要翻译： 当CPU 11从​​客户端计算机30到32接收到对存储在存储装置10中的文件的写入请求时，引用该对象文件的对象控制表，并确认该对象文件的WORM属性。 CPU 11参考WORM范围控制表，并确定写入对象范围是否被设置为WORM范围。 当写入对象范围未设置为WORM范围时，CPU 11执行对主题文件的写入。 当WORM表单设置为写入数据时，CPU 11更新WORM范围控制表，并为写入的数据设置WORM表单。

摘要： To provide a storage system capable of cutting back the resource while obtaining a WORM function. In the storage system, a controller (110) functions to: obtain, when a write request is made by a computer (300), information on one of logical devices that is a target of a write process, from a memory module (140); and inform, when the logical device is set to unwritable, a signal indicating that the logical device is set to unwritable, to the computer (300). An interface (200) functions to: reference meta-information held in a disk drive (130) to obtain a list of files that are not accessed for a predetermined period; secure a logical device that is capable of storing the files on the obtained list of files; and cause the controller (110) to store, in the logical device, the files on the list of files and set the logical device that stores the files in a manner that makes information stored in the memory module (140) unwritable.

摘要： To provide a storage system and a file management device which enable obtaining a file, without designating detailed information. A client is provided with a read request module that sends a file read request containing information corresponding to a file name and an archived date of the file. A WORM archive server is provided with a file identifying module that extracts information corresponding to the file archived date and the file name from the file read request that was received from the client, and identifies the latest archived file with the file name registered before the archived date corresponding to the extracted information from among files recorded in a storage device, and a file sending module that sends the identified data to the client that sent the request.

摘要： The present invention relates to a migration of a file from a path denotative NAS server to an ID denotative NAS server. In a file management device a migration-use path denotative NAS access section obtains a file deposit location from the path denotative NAS server, selects a migration target file based on the deposit location, and sends a read request with the deposit location of the migration target file to the path denotative NAS server, so as to obtain the migration target file. A migration-use denotative NAS access section generates a write request with the migration target file, sends it to the ID denotative NAS servers, and writes the file therein. In addition, the migration-use ID denotative NAS access section registers a GUID received from the ID denotative NAS servers in a file name/GUID management table, together with the file name of the migration target file.

摘要： Difference information between two snapshots from a first point-in-time snapshot, which has been copied, to an N.sup.th point-in-time snapshot, which constitutes the latest point-in-time snapshot, is acquired to a memory module. The memory module stores two or more pieces of difference information. The two or more pieces of difference information comprise difference information that shows the difference between a first point-in-time snapshot and any snapshot other than the first point-in-time snapshot of N snapshots. Copy difference information, which is information that shows the difference between the first point-in-time snapshot and a specified snapshot from among N snapshots, and which is used in copying the specified snapshot, is created on the basis of the two or more pieces of difference information.

摘要： In a cluster type NAS, it is necessary to copy file data between disk devices of servers upon migration of a file system or a part of the file system. A server includes a control table for managing a file system or a part of the file system, and a mapping table for managing a relation between a logical device of a disk subsystem and a logical unit recognized by a server, and in response to an instruction to execute migration of the file system from a first server to a second server, the mapping table is referenced to send an instruction to update the relation between the logical device and the logical unit to the second server, and the second server newly recognizes a logical unit and updates a management server identifier of the control table.

摘要： In order to access a distributed file system (DFS) of the present invention using a conventional protocol such as the one for an NFS or a CIFS without making a modification on a client side, a gateway unit for receiving a conventional protocol and performing processing in conformity the protocol is provided for a DFS server. The gateway unit emulates a directory structure in a file system such as the NFS or CIFS. When the DFS is a write-once read-many file system, update processing is converted into processing for creating a new generation file, and reference processing is converted into access to a latest generation file in a generation-managed file group. The gateway unit then accesses a DFS file via a DFS processing unit.

摘要： A problem with a journaling file system is that the load on input/output processing executed between a server and a storage system is increased because a journal log is written when the file system is updated and updated data is written when flush processing is executed. In a system according to the present invention, a storage system that has received journal logs from a server uses updated data included in the journal logs to execute flush processing.
