University of New Hampshire Assigned Patent

University of New Hampshire, Durham, NH, has been assigned a patent (10,013,359) developed by Fekete, Andras Krisztian, Fremont, NH, and Varki, Elizabeth, Lee, NH, for a “redundant disk array storage system and method using heterogeneous disks and a lookup table.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A redundant disk array method includes allocating identically sized logical blocks of storage units together to form a stripe on each of several data storage devices, at least two of the logical blocks in the stripe being located on different data storage devices, generating a lookup table representing a mapping between a logical location of each logical block in the stripe and a physical location of the respective logical block on the corresponding data storage device, and writing data to the physical locations of each logical block in the stripe, the physical locations being obtained from the lookup table. In some cases, at least two of the data storage devices are heterogeneous, and at least two of the data storage devices have a different total number of logical blocks.”

The patent application was filed on December 18, 2015 (14/974,429).
