摘要： Described are embodiments directed at persistent handles that are used to retain state across network failures and server failovers. Persistent handles are requested by a client after a session has been established with a file server. The request for the persistent handle includes a handle identifier generated by the client. The server uses the handle identifier to associate with state information. When there is a network failure or a server failover, and a reconnection to the client, the handle identifier is used to identify replayed requests that if replayed would create an inconsistent state on the server. The replayed requests are then appropriately handled.

摘要： Systems and methods are disclosed for clients and servers operating in a scaled cluster environment. Efficiencies are introduced to the process of connecting a client to a clustered environment by providing the client with the ability to attempt a connection with multiple servers in parallel. Servers operating the in the clustered environment are also capable of providing persistent storage of file handles and other state information. Ownership of the state information and persistent handles may be transferred between servers, thereby providing clients with the opportunity to move from one server to another while maintaining access to resources in the clustered environment.

摘要： Described are embodiments directed at providing a witness service that sends notifications with a resource state to clients. Embodiments provide a protocol that includes various messages for registering and receiving notifications regarding the state of a resource. The protocol may include a message for requesting node information from a first node in a cluster. The node information identifies nodes in the cluster that provide a witness service, which monitors a resource. The protocol includes a message that is used to register with the witness service for notifications regarding a state, or state change, of a network or cluster resource. The protocol also includes messages for sending notifications with state information of the resource.

摘要： A lease system is described herein that allows clients to request a lease to a remote file, wherein the lease permits access to the file across multiple applications using multiple handles without extra round trips to a server. When multiple applications on the same client (or multiple components of the same application) request access to the same file, the client specifies the same lease identifier to the server for each open request or may handle the request from the cache based on the existing lease. Because the server identifies the client's cache at the client level rather than the individual file request level, the client receives fewer break notifications and is able to cache remote files in more circumstances. Thus, by providing the ability to cache data in more circumstances common with modern applications, the lease system reduces bandwidth, improves server scalability, and provides faster access to data.
摘要翻译：这里描述了允许客户端向远程文件请求租赁的租赁系统，其中租赁允许使用多个句柄跨多个应用访问文件，而不需要对服务器进行额外的往返。当同一客户端上的多个应用程序（或同一应用程序的多个组件）请求访问同一个文件时，客户机为每个打开的请求指定与服务器相同的租约标识符，或者可以根据现有租约处理来自缓存的请求。因为服务器在客户端级别而不是单独的文件请求级别识别客户端的缓存，所以客户端接收到更少的中断通知，并且能够在更多情况下缓存远程文件。因此，通过提供在现代应用中更常见的情况下缓存数据的能力，租赁系统降低带宽，提高服务器可扩展性，并提供更快速的数据访问。

摘要： An application instance identifier is employed with various systems and methods in order to provide a requestor with continuous access to a resource when operating in a client clustered environment. A requestor residing on a first client may attempt to access a resource. The first client sends a request to access the resource. The request may be associated with an application instance identifier that identifies the requestor. At some point, the first client fails and the requestor is associated with a second client via a failover mechanism. The second client sends a second request to access the resource on behalf of the requestor. The second request is associated with the requestor's application instance identifier. The application instance identifier is used to identify the second request as belonging to the same requestor as the first request, thereby granting the second request to access the resource while avoiding a conflict situation.

摘要： Aspects of the subject matter described herein relate to directory oplocks. In aspects, a file system filter is inserted in a filter stack between requesters of directory oplocks and a file system that stores file system objects. The file system filter receives requests for directory oplocks and subsequently monitors for requests to access file system objects that are inconsistent with the directory oplocks. To provide directory oplock mechanisms, the file system filter may use alternate data streams if provided by the file system or may independently maintain information usable to maintain and release directory oplocks. A directory oplock may affect ancestors and descendants of the directory depending on constraints imposed by the oplock.
摘要翻译：本文描述的主题的方面涉及目录操作。在方面，文件系统过滤器插入到目录操作系统的请求者和存储文件系统对象的文件系统之间的过滤器堆栈中。文件系统过滤器接收目录操作锁的请求，并随后监视访问与目录oplock不一致的文件系统对象的请求。为了提供目录操作机制，文件系统过滤器可以使用替代数据流，如果由文件系统提供的，或者可以独立地维护可用于维护和释放目录操作的信息。目录oplock可能会影响目录的祖先和后代，这取决于oplock所施加的约束。
