    Abstract: 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.

    Abstract: 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.

    Abstract translation: 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。

    Abstract: 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.

    Abstract translation: 描述的是针对用于在网络故障和服务器故障转移之间保持状态的持久句柄的实施例。 在与文件服务器建立会话之后，客户端请求持久句柄。 对持久句柄的请求包括由客户端生成的句柄标识符。 服务器使用句柄标识符与状态信息相关联。 当出现网络故障或服务器故障切换以及与客户端的重新连接时，使用句柄标识符来识别重播的请求，如果重播将在服务器上创建不一致的状态。 重播的请求被适当地处理。
