American Megatrends Assigned Patent

American Megatrends, Inc., Norcross, GA, has been assigned a patent (9,201,751) developed by Muthirisavenugopal, Vijayarankan, Enoch, Sharon, Maliakal, Jomy, Newark, CA, and Chatterjee, Paresh, Fremont, CA, for a “data migration between multiple tiers in a storage system using policy based ILM for QOS.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Technologies are described for implementing a default migration mechanism in a storage system containing multiple tiers of storage with each tier having different cost and performance parameters. Data that is accessed more frequently can be migrated toward higher performance storage tiers while data that is accessed less frequently can be migrated towards lower performance storage tiers. Default migration behavior can be overridden by user-specified values for tier age residency policy, demotion policy, tier occupancy of volumes, and tier assignment. Data migration can be paused by the user and resumed by the user.“

The patent application was filed on April 18, 2012 (13/449,485).
