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： Provided is a computer system containing plural storage systems which manages the bandwidth of the storage systems in accordance with storage area attributes. The computer system is characterized in that: a control unit incorporates related file information in metadata, the related file information containing information for identifying a second file which to be write-accessed in conjunction with access to a first file by a client computer, and an access type of the write access. The control unit refers to the related file information to obtain the second file and the access type when the first file is accessed by the client computer. The control unit reads, from the obtained second file stored in the disk device, data corresponding to the obtained access type, to store the read data in a cache memory.

摘要： In a system of the present invention in which a file ID is defined for each file, upon receiving a request for accessing a file specifying a file ID from a user, a file server refers to a file management table to obtain a logical disk ID for accessing the file. The file server then refers to a logical disk management table to obtain an I/O path corresponding to the logical disk ID, and accesses a physical disk device by use of the obtained I/O path. When a fault has occurred in an operational I/O path, a file server rewrites the logical disk management tables in all nodes to change the I/O path. This reduces the time taken to switch I/O paths, and hiding the process of switching the I/O paths from the user.

摘要： A network attached storage (NAS) system includes a disk array unit equipped with a copy device that copies data, and a NAS processing unit that provides file service via a network and is connected via a communication path to the disk array unit. The NAS processing unit is equipped with a snapshot management device that manages snapshots. The snapshot management device of the NAS processing unit designates a physical block to be copied as a snapshot. The copy device on the disk array unit copies the designated physical block within the disk array unit to create a snapshot and stores the snapshot in a separated region. The snapshot management device of the NAS processing unit manages meta data of the snapshot data in a manner accessible by the user depending on requirements.

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.
