摘要： In a switched file system, a file switching device is logically positioned between clients and file servers and communicates with the clients and the file servers using standard network file protocols. The file switching device appears as a server to the client devices and as a client to the file servers. The file switching device aggregates storage from multiple file servers into a global filesystem and presents a global namespace to the client devices. The file switching device typically supports a "native" mode for integrating legacy files into the global namespace and an "extended" mode for actively managing files across one or more file servers. Typically, native-mode files may be accessed directly or indirectly via the file switching device, while extended-mode files may be accessed only through the file switching device. The file switching device may manage file storage using various types of rules, e.g., for managing multiple storage tiers or for applying different types of encoding schemes to files. Rules may be applied to pre-existing files.

摘要： Peer-to-peer redundant file server system and methods include clients that determine a target storage provider to contact for a particular storage transaction based on a pathname provided by the filesystem and a predetermined scheme such as a hash function applied to a portion of the pathname. Servers use the same scheme to determine where to store relevant file information so that the clients can locate the file information. The target storage provider may store the file itself and/or may store metadata that identifies one or more other storage providers where the file is stored. A file may be replicated in multiple storage providers, and the metadata may include a list of storage providers from which the clients can select (e.g., randomly) in order to access the file.

摘要翻译：点对点冗余文件服务器系统和方法包括基于由文件系统提供的路径名确定目标存储提供商以联系特定存储事务的客户端以及诸如应用于路径名的一部分的散列函数之类的预定方案。服务器使用相同的方案确定存储相关文件信息的位置，以便客户端可以定位文件信息。目标存储提供商可以存储文件本身和/或可以存储标识存储文件的一个或多个其他存储提供商的元数据。可以在多个存储提供商中复制文件，并且元数据可以包括存储提供商的列表，客户端可以从该列表中选择（例如，随机地）以访问该文件。
