American Megatrends Assigned Two Patents

Virtual disk carousel
American Megatrends, Inc., Norcross, GA, has been assigned a patent (8,930,666) developed by Richardson Brian, Loganville, GA, Sivertsen Clas Gerhard, Lilburn, GA, and Hanes Charles Patrick, Hoschton, GA, for a “virtual disk carousel.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A virtual disk carousel is provided that is capable of creating disk images from optical disks and storing the disk images. The virtual disk carousel includes a bridge device configured to expose disk images stored at the virtual disk carousel to a computer by way of a standard storage device. When the computer performs read requests on the standard storage device exposed by the bridge device, the bridge device receives the requests from the computer, retrieves the appropriate portion of the disk image from the virtual disk carousel, and provides the portion of the disk image to the computer. The bridge device might also include a display and user input controls for managing the operation of the bridge device. The virtual disk carousel might also provide a user interface for managing the disk images, selecting a disk image to be exposed to the computer, and for performing other functions.”

The patent application was filed on June 14, 2010(12/814,873)

Data de-dupe for information storage systems
American Megatrends, Inc., Norcross, GA, has been assigned a patent (8,930,653) developed by Chatterjee Paresh, Fremont, CA, Balakrishnan Narayanan, Milpitas, CA, Ramasamy Senthilkumar, Vriddhachalam, IN, and Mahalingam Anandh, Newark, CA, for a “data de-duplication for information storage systems.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Technologies for eliminating duplicate data within a storage system. De-duplication may be performed done at physical chunk level, where the data is not copied or moved to different location. A logical mapping is modified using a thin de-duplication kernel module that resides between a distributed volume manager, DVM and a logical disk, LD. De-duplication is achieved by changing pointers in the mapping to land at a physical location. De-duplication is performed as post-process feature where duplicates are indentified and the duplicates are marked in the mapping table, thereby claiming free space through de-duplication. Block-level de-duplication in accordance with the above can co-exist with existing storage architectures for thin provisioning and snapshot management.”
