摘要： Provided is a storage system as follows. A server holds a management table that serves to manage a mount point of a file system. The management table stores a file system identifier that uniquely identifies the file system within the storage system, mount point information that indicates the mount point of the file system, and a management server identifier that indicates an identifier of the server that manages the file system. The contents stored in the management table of each server are the same. Upon reception of a request to obtain a file handle, each server returns the file handle requested to be obtained. The file handle indicates, uniquely within the storage system, the storage area on the disk subsystem in which the file relating to the request is stored.

摘要： A storage system capable of cutting back the resource while obtaining a WORM function. 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; and cause the controller (110) to store, 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： A storage system includes a storage device, a shared memory, and first and second file server devices that each exclusively manages a respective portion of data stored on the storage device. During operation, the first file server device determines whether the first or second file server device manages data that is subject to the processing of a write command received by the first file server device. When the second file server device manages data that is subject to the processing of the write command, the first file server device transfers only the control data contained in the write command to the second file server device and updates data that is subject to the processing of the write command via the shared memory.

摘要： Provided is a storage system capable of preventing the access performance from a client to a file system from deteriorating even when a file system is migrated among a plurality of file servers. This storage system provided a shared file system having the same namespace to the client accessing the file system. This storage system stores in its memory a first information table storing the correspondence of the file system and the file server mounting the file system, and a second information table storing the correspondence of the file system and the frequency of access by the client to the file system.

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： 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： A computer system for managing log information, enabling correct comprehension of system logs for an identical resource before and after migration among plural nodes. A global ID, being unique in the system, is given to a resource (LU) migrated from one file share server to another. The global ID remains the same in the migration destination file share server after migration and log messages for the resource are obtained based on the global ID.
摘要翻译：一种用于管理日志信息的计算机系统，能够在多个节点之间迁移之前和之后正确理解相同资源的系统日志。在系统中唯一的全局ID被赋予从一个文件共享服务器迁移到另一个文件共享服务器的资源（LU）。迁移目的地文件共享服务器的全局ID在迁移后保持不变，并且基于全局ID获取资源的日志消息。
