摘要： A snapshot copy facility maintains information indicating block ownership and sharing between successive versions by delegating block reference counts to parent-child relationships between the file system blocks, as indicated by block pointers in inodes and indirect blocks. When a child block becomes shared between a parent block of the production file and a parent block of a snapshot copy, the delegated reference count is split among the parent blocks. This method is compatible with a conventional data de-duplication facility, and avoids a need to update block reference counts in block metadata of child blocks of a shared indirect block upon splitting the shared indirect block when writing to a production file.
摘要翻译：快照复制设备通过将块引用计数委托给文件系统块之间的父子关系来维护指示块所有权和连续版本之间的共享的信息，如inode和间接块中的块指针所指示的。当子块在生产文件的父块和快照副本的父块之间共享时，委托引用计数在父块之间分割。该方法与传统的重复数据删除设备兼容，并且避免在写入生产文件时分割共享间接块时更新共享间接块的子块的块元数据块中的块引用计数。

摘要： A snapshot copy facility maintains information indicating ownership and sharing of child nodes in the hierarchy of a file between successive versions by delegating reference counts to the parent-child relationships between the nodes, as indicated by pointers in the parent nodes. When a child node becomes shared between a parent node of the production file and a parent node of a snapshot copy, the delegated reference count is split among the parent nodes. This method is compatible with a conventional data de-duplication facility, and avoids a need to update reference counts in metadata of child nodes of a shared intermediate node upon splitting the shared intermediate node when writing to a production file.
摘要翻译：快照复制工具通过将参考计数委托给父节点之间的父子关系来指示在连续版本之间的文件层次结构中的子节点的所有权和共享信息。当子节点在生产文件的父节点和快照副本的父节点之间共享时，委托引用计数在父节点之间拆分。该方法与常规的重复数据删除设备兼容，并且避免在写入生产文件时分割共享中间节点时更新共享中间节点的子节点的元数据中的引用计数。

摘要： A method is used in managing logical views of directories. A directory logical view is created from a primary logical view. The primary logical view includes a set of storage objects. The directory logical view includes a subset of the set of storage objects. A root of the directory logical view indicates a file directory. The file directory includes the subset of the set of storage objects in a hierarchy. A mapping object is created for the directory logical view. The mapping object manages access to the subset of the set of storage objects. The mapping object for the directory logical view is a version of a mapping object for the primary logical view. Information is removed from the mapping object for the directory logical view. Information remained in the mapping object after removing the information is associated with the file directory.

摘要： A method is used in managing concurrent I/Os in file systems. A first and second I/O requests are received. The first I/O request is directed to a first portion of a file and the second I/O request is directed to a second portion of the file. A first range lock for the first portion is obtained and a second range lock for the second portion is obtained. The first and second I/O requests are performed concurrently. The second I/O request starts performing I/O on the second portion of the file before the first I/O request finish performing I/O on the first portion of the file.

摘要： A method for processing digital video data intended for normal mode display to obtain corresponding digital video data for trick-mode display includes modifying the normal mode digital video data to achieve a substantially uniform delivery rate to a video client. This results in smoother trick-mode playback. The modified normal mode digital video data is saved as a trick-mode file. When trick-mode playback is requested, a video-server retrieves data from the trick-mode file.

摘要： A pin clamp assembly having a housing, locating pin, at least one finger, a drive rod and an actuator is provided. At least a portion of the locating pin may be extendable exterior of the housing. The finger is located adjacent the locating pin and movable relative thereto. The drive rod is movable and is engagable with the finger to move the finger between clamped and unclamped positions. The actuator drives the locating pin and the drive rod. Movement of the locating pin and drive rod is linear only and no rotational movement of the locating pin and drive rod is employed to move the finger between clamped and unclamped positions.
