摘要： This invention is a system and a method for operating a storage server that provides read or write access to a data in a data network using a new architecture. The method of processing I/Os in response to a request by a client of the storage server executes one or more services communicated by a policy engine. The I/Os received from the application are tagged and catalogued to create co-related I/O patterns. The policy engine is then updated with the results of processing the I/Os after executing services on those I/Os.

摘要： A method is used in managing updating of metadata of file systems. A reference to a change to metadata of a file of a file system is stored in a global sync list configured to store changes to metadata of a plurality of files of a plurality of file systems. The change to the metadata of the file is stored in a journal upon receiving an I/O request for the file of the file system. The journal includes metadata transactions upon the plurality of files of the plurality of the file system. The change to the metadata of the file of the file system is applied to metadata of the file system organized on a storage device using the reference to the change stored in the global sync list.

摘要： A method is used in enhancing memory buffering by using secondary storage. A buffer cache pool is supplemented with a secondary storage. A portion of a volatile memory of a data storage system is reserved as the buffer cache pool. The buffer cache pool includes a set of buffer cache objects for storing file system data and metadata. The secondary storage includes a set of data blocks. A first buffer cache object of the set of buffer cache objects is aged out by copying contents of the buffer cache object to a data block of the secondary storage. Contents of the first buffer cache object are retrieved from the secondary storage by copying contents of the data block of the secondary storage to a second buffer cache object of the set of buffer cache objects of the buffer cache pool.

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 file system has files constructed of an inode for each file, indirect blocks, and allocation units of file system data blocks. Each of the allocation units has one of the file system data blocks or a plurality of the file system data blocks having contiguous file system block numbers. Each file in the file system has a respective allocation unit size attribute specifying an allocation unit size of each and every allocation unit in the file, and the files in the file system have allocation units of different allocation unit sizes. By using larger allocation units for larger files, there is a reduction in the number of indirect blocks in the files without a corresponding loss in performance, and a reduction in the time needed for the UNIX FSCK utility to check file system consistency.

摘要： A file server has a data compression facility and also a snapshot copy facility or a data de-duplication facility that shares data blocks among files. Compression of the file data on a file system block basis leads to a problem of partially used file system data blocks when the data blocks are shared among files. This problem is solved by partial block allocation so that file system data blocks are shared among files that do not share identical data. Block pointers in the file mapping metadata point to virtual blocks representing the compressed data blocks, and associated virtual block metadata identifies portions of file system data blocks that store the compressed data. For example, a portion of a file system data block is identified by a sector bitmap, and the virtual block metadata also includes a reference count to indicate sharing of a compressed data block among files.
摘要翻译：文件服务器具有数据压缩设施，以及在文件之间共享数据块的快照复制设备或重复数据删除设备。在文件系统块上压缩文件数据导致当文件之间共享数据块时部分使用的文件系统数据块存在问题。这个问题是通过部分块分配来解决的，因此文件系统数据块在不共享相同数据的文件之间共享。文件映射元数据中的阻止指针指向表示压缩数据块的虚拟块，以及相关联的虚拟块元数据标识存储压缩数据的文件系统数据块的部分。例如，文件系统数据块的一部分由扇区位图识别，并且虚拟块元数据还包括指示文件之间的压缩数据块共享的引用计数。

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： Consistent updates are made automatically over a wide-area IP network, concurrently with read-only access to the remote copies. A replication control protocol (RCP) is layered over TCP/IP providing the capability for a remote site to replicate and rebroadcast blocks of the remote copy data to specified groups of destinations, as configured in a routing table. A volume multicast layer over RCP provides for multicasting to specified volume extents of the blocks. The blocks are copied at the logical level, so that it does not matter what physical structure is used for storing the remote copies. Save volumes buffer the remote copy data transmitted between the primary or secondary file system volume and the IP network, in order to ensure independence between the replication process, the IP transport method, and the primary file system being replicated.
