摘要： Snapshots are implemented by combining original data in a place where an operational volume has been updated with data in a place where the operational volume has not been updated. A snapshot management table maintains a value indicating that update has not been conducted, or a storage place of original data, for each of combinations of blocks in the operational volume and the snapshots. If there is a snapshot in which update has not been conducted in a update place at the time of update, then original data is copied and the snapshot management table is updated. The copied original data is managed by a difference block management table, which has a value indicating whether respective snapshots are referencing the data. If a snapshot is deleted, then the value indicating that the snapshot is referencing is altered in all entries in the difference block management table.
摘要翻译：快照是通过将操作卷更新的地方的原始数据与操作卷未更新的地方的数据相结合来实现的。对于操作卷和快照中的每个块的组合，快照管理表维护指示尚未进行更新的值或原始数据的存储位置。如果在更新时没有在更新位置进行更新的快照，则会复制原始数据，并更新快照管理表。复制的原始数据由差分块管理表管理，差分块管理表具有指示各个快照是否参考数据的值。如果快照被删除，则表示快照正在引用的值在差异块管理表的所有条目中被更改。

摘要： A file server has plural NAS nodes having three processors dispersed in function, a shared cache memory shared between the plural NAS nodes and backed up by a battery, and plural storage devices. A log area for storing data with respect to an access request received by each NAS node is arranged in the shared cache memory. A network processor stores the data with respect to the access request to the log area, and transfers the data of the memory by a DMA at a reading time. Even when a failure is happened in a certain NAS node, another NAS node restores a file system using the log and continues processing to store the data with respect to the access request to the shared cache memory.

摘要： Provided is a computer system in which a plurality of virtual machines operate on a host computer. The host computer has a time subtraction table for storing the time subtraction with the respective virtual machines, and a log collection unit for collecting the logs of the respective virtual machines. The log contains a time stamp which shows at least the log output time. The log collection unit corrects the time stamp of the logs collected from the respective virtual machines based on the time subtraction stored in the time subtraction table. According to this computer system, the logs of the virtual machines operating in a time series that is different from the time series of the host computer can be collected upon integrating the time series of the virtual machines and the host 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： Flicker which occurs when a television camera images an object under illumination of a flickering light source such as fluorescent lamp is minimized without causing sensitivity of a photoelectric conversion element and hence the camera to be degraded under a non-flickering light source. The television camera includes an automatic iris control device, an automatic gain control circuit, a microcomputer, a photoelectric conversion element and an integration circuit for integrating output signal of the photoelectric conversion element for each field period. The microcomputer sets a signal storage time of the photoelectric conversion element to a value by which flicker noise can be restricted when flicker is detected on the basis of a change of an output signal of the integration circuit and sets it to another value when a change of light source is detected on the basis of a change of iris value and gain.

摘要： A sheet processing apparatus arranged in a space between an image reading section for reading an image and an image formation section for forming an image on a sheet includes a carry-in path guiding a sheet from a carry-in entrance; a relay roller provided in the carry-in path to relay and transport the sheet; a first transport path positioned on a downstream side of the relay roller and having a carry-in roller to transport the sheet from the carry-in path to the first collection tray; and a second transport path branched from the carry-in path and having a branch roller to transport the transported sheet to the second collection tray. The relay roller shifts the sheet in a direction crossing the transport direction while a front end of the sheet enters the first transport path or the second transport path, and arrives at the carry-in roller or the branch roller.
