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： 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 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.
