  • Patent number: 8935560
    Abstract: A method, system and apparatus of a file locking within a network file system federated namespace is disclosed. In one embodiment, a method includes accessing a target file in a storage medium over a network through an intermediate proxy server using a processor. The storage medium may be any one storage medium of a group of storage mediums on the network forming a data sharing cluster. In addition, the method includes locking the target file in the storage medium through a lock protocol to enable an access to modify the target file to at most one user at any given time, via the intermediate proxy server.

  • Patent number: 8527586
    Abstract: The present invention provides a system and method for abstracting multiple network attached storage (“NAS”) locations, providing a single global namespace and a single mount point that is protocol and location-independent. As a result, rather than identifying each NAS and file server by location, access is provided through a single transparent mechanism. In order to maintain transparency, the present invention provides a way to reconcile the different naming practices for different file server protocols.
