An electric camera includes an image sensing device with a light receiving surface having N vertically arranged pixels and an arbitrary number of pixels arranged horizontally, N being equal to or more than three times the number of effective scanning lines M of a display screen of a television system, a driver to drive the image sensing device to vertically mix or cull signal charges accumulated in individual pixels of K pixels to produce, during a vertical effective scanning period of the television system, a number of lines of output signals which corresponds to 1/K the number of vertically arranged pixels N of the image sensing device, K being an integer equal to or less than an integral part of a quotient of N divided by M, and a signal processing unit having a function of generating image signals by using the output signals of the image sensing device.

A file management sub-system executes file migration without causing an unintended drop in the response time or the like. When a management computer issues a file migration direction, a file storage apparatus notifies client computer associated with a migration target file that file migration is scheduled. When postponement or suspension of file migration is requested by the client computer, the file migration is postponed or suspended.

A storage system 1000 providing a storage area to an external device 1500 comprises a plurality of storage apparatuses 1100, 1200 and 1300 of different performance capabilities, and a storage controller 2600. The storage controller 2600 holds storage cost coefficients 3202 of the respective storage apparatuses 1100, 1200 and 1300, user cost allocation information 3302 for each user using the storage system 1000 from the external device 1500, and user cost distribution information 3402 that defines, for each user, proportions of an available space amount distributed to the storage apparatuses 1100, 1200 and 1300. The storage controller 2600 calculates an ideal utilization 3502 for each user, from the storage cost coefficients 3202 and the user cost distribution information 3402, and allocates, for each user, the ideal utilization 3502 to each of the storage apparatuses 1100, 1200 and 1300, in the order of the performance capabilities from highest to lowest.

A storage system including: a storage device for storing a file; a plurality of file systems for managing the file; and a plurality of NAS servers that control access from a client to the file systems via a global namespace formed by grouping local namespaces for the one or more file systems; wherein, each NAS server includes a memory to store global namespace management information including global paths of the file systems; one NAS server of the NAS servers accepts a request to obtain snapshots of the file systems from external of the storage system; the one NAS server instructs itself and the other NAS servers to obtain snapshots of the file systems; the one NAS server and the other NAS servers obtain the snapshots of the file systems, and inform the one NAS server of snapshot identifiers and of local paths of the snapshots; the one NAS server makes snapshot management information including global paths of the snapshots based on each of the snapshot identifiers received from the other NAS servers and each of the global paths of file systems corresponding to the snapshots, included in the namespace management information so that both the global paths of the file systems and the global paths of the snapshots are configured on the same global namespace simultaneously, with a directory configuration of the snapshots being same in configuration layout as a directory configuration of the file systems; and the one NAS server informs the other NAS servers of the snapshot management information.
摘要:
A storage system including: a disk device including an original volume and a plurality of snapshot generations; and a storage control unit which includes a processor unit. The processor unit receives write data to a storage area of the original volume, and determines whether data stored in the storage area of the original volume is already copied to the snapshot volume or not; if the data stored in the storage area of original volume is not already copied to snapshot volume, the processor unit copies the data from original volume to the snapshot volume, when a use capacity of the snapshot volume is larger than threshold amount by the copy, the processor unit indicates a specified snapshot generation, the processor unit migrates data of the specified snapshot generation from the snapshot volume to tape device; the processor unit deletes information of the specified snapshot generation in the snapshot volume.
摘要:
The correspondence relationship between local paths in local namespaces for snapshots FS0-SNAP0, FS1-SNAP0, and FS2-SNAP0 of file systems FS0, FS1, and FS2 and global paths in a global namespace for those snapshots is defined so that the directory configuration in the global namespace of the snapshots FS0-SNAP0, FS1-SNAP0, and FS2-SNAP0 becomes the same as the directory configuration in the global namespace of the file systems FS0, FS1, and FS2.

A computer is provided with: a device related value acquisition unit that acquires a device related value (for example a LUN), which is a value relating to a device; a calculation formula including a first variable in which the device related value is substituted; a device identification value calculation unit that calculates a device identification value of a device corresponding to the acquired device related value by substituting this device related value in the first variable; and a correspondence registration unit that registers the calculated device identification value and the acquired device related value in an electronic information resource.
摘要:
A system renting out file servers to many companies in a data center has a security problem so that the user cannot perform operation needing manager authorization in the file servers. An OS provides execution administrative area information of an application program designated by process information which can specify the range of an accessible device to operate the server system of the customer in the administrative area information.

A storage device having a volume for storing data sent from a host computer and transferring the data stored in the volume to a sub storage device via a network, comprises: a retrieval unit for retrieving a snapshot retaining change data generated in the volume during a time period between a given time and another given time, and a maximum transfer size of the network between the storage device and the sub storage device; and a control unit for controlling so as to store data exceeding a maximum transfer size in the area of another snapshot, when the size of a created snapshot exceeds the maximum transfer size.
摘要:
When any file sharing server among a plurality of file sharing servers configuring a virtual file system receives a backup requests from a backup server, the file sharing server that received the backup request searches a file sharing server managing the files to be backed up among the plurality of file sharing servers, and transfers the backup request to the searched file sharing server. The file sharing server that received the transfer of the backup request transfers the backup data to the media server via a connection server.
