A system and method enables de-duplication in a storage system architecture comprising one or more volumes distributed across a plurality of nodes interconnected as a cluster. De-duplication is enabled through the use of file offset indexing in combination with data content redirection. File offset indexing is illustratively embodied as a Locate by offset function, while data content redirection is embodied as a novel Locate by content function. In response to input of, inter alia, a data container (file) offset, the Locate by offset function returns a data container (file) index that is used to determine a storage server that is responsible for a particular region of the file. The Locate by content function is then invoked to determine the storage server that actually stores the requested data on disk. Notably, the content function ensures that data is stored on a volume of a storage server based on the content of that data rather than based on its offset within a file. This aspect of the invention ensures that all blocks having identical data content are served by the same storage server so that it may implement de-duplication to conserve storage space on disk and increase cache efficiency of memory.

Disclosed is a method in a computer system capable of executing a version control program, wherein the method operates within the version control program for incorporating changes to software releases. The method creates a project archive object that manages all resources for each of the software releases and then creates a branch in the project archive object in order to establish a new project revision object of the project archive objects. Next, a project revision object is established and is disposed on the branch for incorporating a revision of the project archive object. After this, archive objects are added to the project revision object and revisions are received from a user to each of the archive objects. A change object is established for the project revision, which logically groups a set of revisions to be released. A stream is then created from the project revision object in order to establish a new project revision object of the project archive object, thereby establishing the new project revision object as a software release object. The software release object is then disposed on the stream for incorporating a revision of the project archive object. Finally, the change object is applied to the software release object after it is determined that a change is ready for release.
