American Megatrends Assigned Patent

American Megatrends, Inc., Norcross, GA, has been assigned a patent (8,402,209) developed by four co-inventors for "provisioning space in a storage system."

The co-inventors are Paresh Chatterjee, Fremont, CA, Venkatesh Ramamurthy, Lilburn, GA, Loganathan Ranganathan, and Anandh Mahalingam, Fremont, CA.

The abstract of the patent published by the U.S. Patent and Trademark Office states: "Dynamic provisioning of available space in a storage system without having to configure partitions at system start-up is presented. A system table may be maintained with entries corresponding to provisions within the available physical capacity of a storage system. A volume table may be maintained that includes entries corresponding to territories within a logical storage volume. When a data write operation is requested, a determination may be made as to whether physical space has been allocated for the territory in the volume that is to be written. If physical space has not yet been allocated, the necessary physical space may be allocated for the territory within the logical volume that is to receive the written data and the requested write operation may be performed. Metadata can be written to disk as to simplify recover from system crashes and unclean shutdowns."

The patent application was filed on April 16, 2009 (12/425,123).
