摘要： The present invention, in particular embodiments, provides methods, apparatuses and systems directed to providing a Wide Area File System that is robust against network connectivity issues. In particular implementations, the present invention provides a WAFS disconnected-mode read-write access that provides for a more seamless user experience against WAN or other network connectivity failures. Specific embodiments provide for management, at a network device such as an EFG node, of file objects previously opened during a connected state with a remote file server appliance, creation of new file objects during a disconnected state and re-synchronization of those file objects (data and meta-data) when a connection becomes available.

摘要： Methods, apparatuses, and systems directed to improving shared file access in wide area network file systems. In a particular implementation, one or more elements of a wide area file system cooperate to keep an original file intact on a remote file server until a new copy of the same file is flushed to the remote file server. In a particular implementation, rename operations identifying a source and a target in connection with application-level save operations are executed as two composite operations including creation of the target, and a delayed deletion of the source. The delay after which the source is deleted can be configured to be just large enough so that the application save operation on a local cache can be completed.
摘要翻译：旨在改善广域网文件系统中共享文件访问的方法，设备和系统。在特定实现中，广域文件系统的一个或多个元素协作以将原始文件保持在远程文件服务器上，直到相同文件的新副本被刷新到远程文件服务器。在特定实现中，重新命名与应用程序级保存操作相关联的源和目标的操作被执行为包括目标的创建以及源的延迟删除的两个复合操作。源被删除的延迟可以被配置为足够大，以便可以完成本地缓存上的应用程序保存操作。

摘要： A multi-level cache comprises a plurality of cache levels, each configured to cache I/O request data pertaining to I/O requests of a different respective type and/or granularity. The multi-level cache may comprise a file-level cache that is configured to cache I/O request data at a file-level of granularity. A file-level cache policy may comprise file selection criteria to distinguish cacheable files from non-cacheable files. The file-level cache may monitor I/O requests within a storage stage, and may service I/O requests from a cache device.

摘要： A process for opening and reading a file over a network, including a WAN. An edge file gateway receives a request from an application to open a file cached with the edge file gateway at one point on a network and stored on a file server connected to a central server at another point on the network. The edge file gateway forwards the request to open the file to the central server, along with any offsets and lengths stored from any previous requests to read the file. The central server responds by sending any file data described in the offsets and lengths to the edge file gateway. When the edge file gateway receives a read request, the edge file gateway stores the offset and length for the request, if a predefined storage limit is not exceeded, and attempts to satisfy the request from cached file data.
摘要翻译：通过网络打开和读取文件的过程，包括WAN。边缘文件网关接收来自应用程序的请求，以在网络上的一个点处打开与边缘文件网关缓存的文件，并存储在连接到网络上另一点的中央服务器的文件服务器上。边缘文件网关转发请求以将文件打开到中央服务器，以及从任何先前请求读取文件所存储的任何偏移量和长度。中央服务器通过将偏移和长度中描述的任何文件数据发送到边缘文件网关进行响应。当边缘文件网关接收到读取请求时，如果未超过预定义的存储限制，边缘文件网关将存储请求的偏移量和长度，并尝试从缓存的文件数据中满足请求。

摘要： Systems and methods for managing data input/output operations are described. In one aspect, a device driver identifies a data read operation generated by a virtual machine in a virtual environment. The device driver is located in the virtual machine and the data read operation identifies a physical cache address associated with the data requested in the data read operation. A determination is made regarding whether data associated with the data read operation is available in a cache associated with the virtual machine.
