Nirvanix, Inc. - San Diego CA

International Classification:

G06F 9/52

US Classification:

718105

Abstract:

A method for balancing loads among a plurality of data storage devices, includes: receiving a request from a user device to download a data file; identifying a first set of storage devices containing the requested data file, wherein the first set comprises one or more storage devices; identifying a first storage device from the set that is currently least busy among the storage devices in the first set, and directing the first storage device to serve the request; determining if the first storage device is too busy; and if the first storage device is too busy copying the requested data file to a second storage device which did not previously store the data file, thereby adding the second storage device to the first set of storage devices containing the requested data file.

US Classification:

707705, 707600, 707609, 707694, 707821, 709201

Abstract:

A method for managing storage and access to data files stored in a storage delivery network comprising a plurality of geographically distributed storage nodes, the method including: receiving a file request from a user, wherein the user is associated with a service level agreement (SLA) containing one or more policies governing handling of file requests from the user; determining if the SLA dictates redirecting the file request to a predetermined storage node; if the SLA dictates redirecting the file request to a predetermined storage node, redirecting the file request to the predetermined storage node; otherwise, identifying all storage nodes from the plurality of geographically distributed storage nodes that are near enough to the user based on one or more predetermined criteria; identifying a nearest storage node from among the near enough storage nodes; and redirecting the user request to the nearest storage node.
