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LAN4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进行连接。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： 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 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 conducting remote copy functions such that, when data is updated at a local site, contents of the update can be referred to in real time by storage at a remote site. A disk-control unit at a remote site receives file data written in accordance with an update of a file in a storage system at a local site and a history of the file-management information from the storage system at the local site and stores the data and the history. A file-system processing unit refers to the history and updates the file-management information in a file-system cache in accordance with the update of the file in the storage system at the local site. When a client issues a read request, the file-system processing unit refers to the file-management information updated in the file-system cache and transfers the contents of the update of the file to the client.
