[February 27, 2013]

NetApp Assigned Patent for Out of Order Delivery for Data and Metadata Mirroring in a Cluster Storage System

(Targeted News Service Via Acquire Media NewsEdge) By Targeted News Service ALEXANDRIA, Va., Feb. 27 -- NetApp, Sunnyvale, Calif., has been assigned a patent (8,386,425) developed by Harihara S. Kadayam, Sunnyvale, Calif., and Hari Shankar, San Jose, Calif., for "out of order delivery for data and metadata mirroring in a cluster storage system." The abstract of the patent published by the U.S. Patent and Trademark Office states: "Described herein are a system and method for remote mirroring of data and metadata from a local node to a remote node using out-of-order delivery (OOD), while also providing data integrity at the remote node. OOD may utilize increased throughput of multiple connection paths between nodes. A mirroring layer/engine executing on the local node may receive related groups of data and metadata for storing to the remote node, each related group comprising one or more data sets and one metadata set that describes and is associated with each of the one or more data sets in the related group. The mirroring layer provides data integrity at the remote node by ensuring that the metadata set of a related group is stored to the remote node only after all the data sets in the related group are stored to the remote node, thus ensuring data consistency at the remote node." The patent application was filed on Feb. 19, 2010 (12/709,185).
