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： 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： The object of the present invention is to maintain redundancy of file without using a centralized controller in a system where a plurality of file servers are connected with each other via a network. Each domain ND within a file storage system 10 includes a file server FS, a monitoring server WS, and a client CL, which are connected with each other via a LAN. When the file server FS detects a failure having occurred in another file server FS included 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 based on the selection the identical file from the copy source server to the copy destination server.
摘要翻译：本发明的目的是在多个文件服务器经由网络彼此连接的系统中，不使用集中控制器来维护文件的冗余。文件存储系统10内的每个域ND包括通过LAN相互连接的文件服务器FS，监视服务器WS和客户端CL。当文件服务器FS检测到在系统中包含的另一个文件服务器FS中发生故障时，认为存储在故障文件服务器FS中的文件的冗余已经减少，然后确定是否负责恢复冗余。如果文件服务器FS已经确定它负责恢复冗余，则它将文件服务器FS选择为文件复制源，将文件服务器FS选择为文件复制目标，然后根据所选择的相同文件从将源服务器复制到复制目标服务器。

摘要： A texture processing for imparting a magnetic orientation in the circumferential direction is applied to a substrate so as to impart a magnetic anisotropy to the magnetic disk in the circumferential direction. An underlying film, a magnetic recording film, a protective film, and a lubricating film are laminated one upon the other on the surface of the substrate. The surface of the magnetic disk has a value of the contact ratio [BH 1.0 nm] falling within a range of 7% to 15% in a region having a height not smaller than 1.0 nm, based on the height at which the contact ratio in the bearing curve of a surface roughness is 50%.

摘要： A nonvolatile semiconductor storage system has multiple nonvolatile semiconductor storage media, a control circuit having a media interface group (one or more interface devices) coupled to the multiple nonvolatile semiconductor storage media, and multiple switches. The media interface group and the multiple switches are coupled via data buses, and each switch and each of two or more nonvolatile chips are coupled via a data bus. The switch is configured so as to switch a coupling between a data bus coupled to the media interface group and a data bus coupled to any of multiple nonvolatile chips that are coupled to this switch. The control circuit partitions write-target data into multiple data elements, switches a coupling by controlling the multiple switches, and distributively sends the multiple data elements to multiple nonvolatile chips.

摘要： Data stored in a plurality of snapshots that can be updated is efficiently updated.A computer system includes a computer that provides a plurality of storage areas and a storage device that stores data read and written in the storage areas. The storage device provides a first volume that stores data shared by the storage areas respectively and a second volume that stores data held in the storage areas respectively. The computer stores storage area management information and a storing flag that shows a storing part of updated data and sets the storing flag in accordance with a request. When the computer receives the update of the data stored in the first volume and the storing flag is set to the second volume, if a second area corresponding to a first area is not allocated to the second volume, the computer updates a second area newly allocated to the second volume to store the location information of the newly allocated second area in the storage area management information correspondingly to the first area.

摘要： This invention addresses to execute an emergency access interception in a widely distributed environment.An access controller 100 manages an access control list (ACL) 110 recording access right to each object, and a black list (BL) 120 recording user information corresponding to the emergency access interception. The access controller 100 receives a request for authentication to access right and judges whether or not the access right is proper, first according to the BL 120 then ACL110. In case where the user information corresponding to the request is recorded in the BL 120, the access controller 100 sends out the user information to other access controllers and instructs them to register it in the black list. This invention effectively actualizes the emergency access interception under the widely distributed environment in case where the interception is required for any user.
