Disney Enterprises Assigned Patent

Distributing and accessing files in a distributed storage system

Disney Enterprises, Inc., Burbank, CA, has been assigned a patent (8,290,919) developed by Sean A. Kelly and Roger B. Milne, Boulder, CO, for a "system and method for distributing and accessing files in a distributed storage system."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A system and method for distributing and accessing files in a distributed storage system uses an ordered list of the storage nodes in the system to determine the storage node on which a file is stored. The distributed storage system includes a cluster of storage nodes and may also include one or more client nodes that participate in the system as storage resources. Each node (client and storage) stores an ordered list of the storage nodes in the system, allowing any of the nodes to access the file. The list is updated whenever a new storage node is added to the system, an existing storage node is removed from the system, or a new storage node is swapped with an existing storage node. Each one of the nodes may independently compute a new mapping of files to the storage nodes when the ordered list is changed."

The patent application was filed on Aug. 27, 2010 (12/870,739)
