摘要： A storage device is provided with a file I/O interface control device and a plurality of disk pools. The file I/O interface control device sets one of a plurality of storage hierarchies defining storage classes, respectively, for each of LUs within the disk pools, thereby forming a file system in each of the LUs. The file I/O interface control device migrates at least one of the files from one of the LUs to another one of the LUs of an optimal storage class, based on static properties and dynamic properties of each file.

摘要： In a distributed file system, when a user requests a computer to create a distributed file, a management computer acquires a list of computers complying with an allocation rule selected by the user from allocation rules taking the performance, security level, reliability level and utility rate into consideration. When the user requests the computer to access the distributed file, on the other hand, the partial files and the server information are collected from each computer. Each computer evaluates the allocation of the partial files based on the selected allocation rule and the server information from each computer, and if required, selects a destination computer and instructs the partial files to be moved to the destination computer.

摘要： In order to manage the various types of attribute information within the storage system, the storage system includes the following databases within a file-access controlling memory: a database for managing index information for managing contents of the files, and an index retrieval program, a database for managing the attribute information on the files, and a database for managing storage positions of blocks configuring a file. When the storage system receives an access request to a file, the utilization of these databases allows the storage system to make the access to the access-target file.

摘要： This invention enables a file to be accessed even during replication while maintaining its consistency. The replication is done among a plurality of distributed storage devices, a file is searched, in response to an access request from a client machine #11, from GUID management databases 13, 23 each of which stores a relationship between a GUID of a file stored in a storage device #0 (#1) and a device ID of a storage device containing an original file. When the storage device #1 does not have the demanded file, a device ID (#0) of a storage device containing its original file is searched from the GUID management database based on a GUID of the file C, and the file C demanded by this the storage device #0 is accessed.

摘要： The redundancy of a file is maintained without using a centralized controller in a system where file servers are connected via a network. Each domain ND within a file storage system includes a file server FS, a monitoring server WS, and a client CL, which are connected via a LAN. When the file server FS detects a failure in another file server FS in the system, it considers that redundancy of a file stored in the failed file server FS has decreased, and then determines whether or not it is responsible for recovering the redundancy. If the file server FS has determined that it is responsible for recovering the redundancy, it selects a file server FS as a file copy source and a file server FS as a file copy destination, and then copies the identical file from the copy source server to the copy destination server.

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.
