摘要： A region of a node is searched to find a content-defined split point. A split point of a node is determined based at least in part on hashes of entries in the node and the node is split based on the determined split point. The search region is searched for the first encountered split point and the node is split based on that split point. That split point is based on a predetermined bitmask of the hashes of the entries in the node satisfying a predetermined condition.

摘要： A method and system for managing storage resources associated with a network having at least one storage resource coupled to at least one server and at least one client over at least one data path. The method and system includes servers managing the storage resource over the data path, and clients directing I/O requests to the storage resources and redirecting I/O requests to the servers upon the detection of a failure condition.

摘要： An improved policy enforcement architecture includes several components that improve the performance of policy enforcement in a hierarchical storage environment. A File System Query instruction permits a richer set of queries to be expressed by a policy engine, thereby permitting more complex policies to be implemented with ease. The File System result is generated at the file server, and only files of interest are forwarded to the policy engine. The file system query advantageously may be applied against a pre-generated index having one more characterizing attributes to further reduce the processing required to retrieve policy data. An Index Build instruction, added to a programming interface, allows a policy engine generate the characterizing indices in advance of use. Index maintenance techniques maintain consistency between the index and the file system to ensure that the policy can be enforced using accurate file information.

摘要： The invention provides a way for computer applications to parse the operating system's file system format without embedding direct knowledge of the format in the applications themselves. By making a file system self-describing, applications running locally on the same computer, or remotely on another computer, can interpret file system data structures if they can access the disk containing the file system. Storage Area Networks (SANs) present a paradigm where multiple computer systems can see the same set of disk resources. This, combined with the invention of self-describing file systems, makes it possible to build applications that are more intelligent and perform better than their counterparts that either embed knowledge of a file system or rely on a file system driver to interpret the structure on behalf of the applications.
摘要翻译：本发明提供了一种计算机应用程序解析操作系统的文件系统格式的方式，而无需将该格式的直接知识嵌入应用程序本身。通过使文件系统自我描述，在同一台计算机上本地运行的应用程序或另一台计算机上的远程应用程序可以解释文件系统数据结构，如果它们可以访问包含文件系统的磁盘。存储区域网络（SAN）提供了多个计算机系统可以看到同一组磁盘资源的范例。这与自描述文件系统的发明结合起来，使构建更智能和执行更好的应用程序成为可能，它们嵌入文件系统的知识或者依靠文件系统驱动程序来代表结构来解释结构的应用程序。
