Dot Hill Assigned Patent

Dot Hill Systems Corp., Longmont, CO, has been assigned a patent (8,751,467) developed by Kent Lee, Ladera Ranch, CA, for a method and apparatus “for quickly accessing backing store metadata.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method, device, and system are provided for accessing metadata in a data storage system. More specifically, a requesting application requests a cache application to allocate a cache page to retrieve metadata from a storage device. After metadata is written to the cache page, the cache page is locked by the requesting application. The cache page is maintained in a locked state by the requesting application. This allows the data stored within the cache page to be quickly accessed and updated by the requesting application without waiting for the cache page to be written back to the storage device after every update to the cache page occurs.“

The patent application was filed on Jan. 18, 2007 (11/624,524).
