American Megatrends Assigned Patent

American Megatrends, Inc. (AMI), Norcross, GA, has been assigned a patent (9,396,067) developed by Subramanian, Srikumar, Newark, CA, Sowrirajan, Raghavan, Fremont, CA, Gopalakrishnan, Sankarji, and Chatterjee, Paresh, Fremont, CA, for a “I/O accelerator for striped disk arrays using parity.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Disclosed herein is an enhanced volume manager, (VM) for a storage system that accelerates input/output, (I/O) performance for random write operations to a striped disk array using parity. More specifically, various implementations are directed to accelerating ‘random writes’, (writes comprising less than a complete stripe of data) by consolidating several random writes together to create a ‘sequential write’, (a full-stripe write) to eliminate one or more read operations and/or increase the volume of new/updated data stored for each write operation. Several such implementations comprise functionality in the VM, (volume manager) for identifying random write I/O requests, queuing them locally in a journal, and then periodically flushing the journal to the disk array as a sequential write request.“

The patent application was filed on April 18, 2012 (13/449,496).
