International Classification:

G06F 15/16

US Classification:

709213, 709216, 709217, 709218, 709248

Abstract:

Aspects of the subject matter described herein relate to synchronizing for directory actions performed while offline. In aspects, file system objects that reside on a remote data store are made available for offline use. While offline, a client receives an indication that a directory is to be deleted or renamed. In response, the client modifies its local copy of the directory and its descendants if any and stores one or more tombstones that include information that the client can use when synchronizing the changes made to the directory when the client is reconnected to the remote data store. When the client reconnects to the remote data store, the client synchronizes changes made while offline with the remote data store. Resolution conflict mechanisms may be used during this synchronization.

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.

International Classification:

G06F 15/16

US Classification:

709223, 709224

Abstract:

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.

US Classification:

707827, 707E1701

Abstract:

The present invention extends to methods, systems, and computer program products for end-to-end optimization of data storage and transmission of data. Details of how data is stored within a data store are exposed to clients and applications. Clients and applications are enabled to makes requests to data stores to obtain data as it is actually stored upon within the data store to eliminate redundant processing of the requested data. Compression and de-duplication of data within a data store are leveraged to increase the efficiency and reduce latency of data transmitted over a LAN or WAN.

International Classification:

US Classification:

709203

Abstract:

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 in 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 identifiers 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.

US Classification:

709227

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.
