摘要： A network caching system has a multi-protocol caching filer coupled to an origin server to provide storage virtualization of data served by the filer in response to data access requests issued by multi-protocol clients over a computer network. The multi-protocol caching filer includes a file system configured to manage a sparse volume that “virtualizes” a storage space of the data to thereby provide a cache function that enables access to data by the multi-protocol clients. To that end, the caching filer further includes a multi-protocol engine configured to translate the multi-protocol client data access requests into generic file system primitive operations executable by both the caching filer and the origin server.

摘要： In one embodiment, the invention provides an apparatus for caching data in a network, with the apparatus including a proxy cache configured to receive request for an object from a client and to fetch data blocks from a server. The proxy cache may be configured to cache the data blocks in a hierarchical relationship within the object. The object may be, for example, a data file or a directory. The data blocks that are cached in the proxy cache define an active data set which is based upon a request from a client.

摘要： In an embodiment, a method to provide data consistency in a storage system, includes: providing, by a server to a proxy cache, a lock associated with a delegated file in the server; in response to a write request from a client, modifying data in a cached copy of the delegated file in the proxy cache; revoking, by the server, the lock associated with the delegated file, in response to a request from another device to access the delegated file so that the delegated file is now a formerly delegated file; and writing the modified data to the formerly delegated file in the server to update the formerly delegated file; and permitting access to the formerly delegated file by the another device.

摘要： The invention provides for managing information for multiple devices. Each of a set of devices retrieves information from a sequence of servers. A device when starting up reads a list of file names, reads information from each file in sequence, and resolves conflicts among files to present a consistent configuration on each restart of each device. A file includes a sequence of pairs. In those cases when two variables have the same name, an operator associated with the second pair indicates whether to overwrite the first value or to edit the first value, such as by appending the second value. One of the pairs indicates the list of file names itself. When the list of file names is changed, the device for which the change is made re-reads the sequence of files and repeats its determination of the pairs, until the list of file names is stabilized.
摘要翻译：本发明提供用于管理多个设备的信息。一组设备中的每一个从服务器序列检索信息。启动时的设备读取文件名列表，依次从每个文件中读取信息，并解决文件之间的冲突，以便在每个设备的每次重新启动时呈现一致的配置。一个文件包含一个对的序列。在两个变量具有相同名称的情况下，与第二对应关联的运算符指示是否覆盖第一个值或者编辑第一个值，例如通过追加第二个值。其中一个对表示文件名本身的列表。当文件名称列表发生变化时，进行更改的设备将重新读取文件序列，并重复其对的确定，直到文件名列表稳定为止。
