Abstract: A distributed data storage system for sharing data among client computers running different types of operating systems by separating metadata from data. Data is stored in storage pools that are accessed by the client computers through a storage network. Metadata is stored in a metadata store and provided to the client computers by a cluster of metadata servers. The client computers communicate with the metadata servers using a Storage Tank protocol and over a control network. Each client computer runs an operating systemspecific client program that provides the client side functions of the Storage Tank protocol. The client program preferably includes a file system interface for communicating with the file system in the storage system and user applications, a client state manager for providing data consistency, and a plurality of operating system services for communicating with the metadata servers.
Abstract translation: 分布式数据存储系统，用于通过从数据中分离元数据，在运行不同类型操作系统的客户端计算机之间共享数 数据存储在客户端计算机通过存储网络访问的存储池中。 元数据存储在元数据存储中，并通过一组元数据服务器提供给客户端计算机。 客户端计算机使用Storage Tank协议和控制网络与元数据服务器进行通信。 每台客户端计算机都运行一个操作系统特定的客户端程序，提供Storage Tank协议的客户端功能。 客户端程序优选地包括用于与存储系统和用户应用程序中的文件系统通信的文件系统接口，用于提供数据一致性的客户端状态管理器以及用于与元数据服务器进行通信的多个操作系统服务。

Abstract: Access to objects of a computing environment is managed. Access to an object of the computing environment is prohibited via one cached entity corresponding to the object, while access to the object is allowed via another cached entity. The cached entities are concurrently maintained for a period of time, but the one cached entity is in a shadow state. In one example, the cached entities are session locks and the object is a file system object.
Abstract translation: 管理对计算环境对象的访问。 通过与对象相对应的一个缓存实体禁止访问计算环境的对象，同时通过另一个缓存实体允许访问对象。 缓存的实体同时维护一段时间，但是一个缓存的实体处于阴影状态。 在一个示例中，缓存的实体是会话锁，对象是文件系统对象。
