NEC Assigned Two Patents

Storage management
NEC Corp., Tokyo, Japan, has been assigned a patent (10,162,573) developed by Suenaga, Masaya, Tokyo, Japan, for “storage management system, storage management method, storage medium and information processing system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “The present invention provides a storage management system that suppresses performance degradation due to Read-Modify-Write. The storage management system includes: a management unit managing a storage system including a first storage medium having a first physical sector size and an alternative storage medium having a second physical sector size smaller than the first physical sector size, an acceptance unit accepting a write request, and a disk processing control unit, when a write area identified by the write request is an area on the first storage medium and the start address or end address of the write area does not correspond to a boundary of a physical sector of the first storage medium, writing data identified by the write request on the alternative storage medium, notifying the host of completion of the write, and then transferring the data from the alternative storage medium to the first storage medium.”

The patent application was filed on September 24, 2014 (14/495,021).

Large-scale, dynamic graph storage and processing
NEC Corp., Tokyo, Japan, has been assigned a patent (10,162,550) developed by Rao, Kunal, Coviello, Giuseppe, Plainsboro, NJ, Chakradhar, Srimat, Manalapan, NJ, Bhattacherjee, Souvik, College Park, MD, and Cadambi, Srihari, Princeton, NJ, for “large-scale, dynamic graph storage and processing system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A graph storage and processing system is provided. The system includes a scalable, distributed, fault-tolerant, in-memory graph storage device for storing base graph data representative of graphs. The system further includes a real-time, in memory graph storage device for storing update graph data representative of graph updates for the graphs with respect to a time threshold. The system also includes an in-memory graph sampler for sampling the base graph data to generate sampled portions of the graphs and for storing the sampled portions of the graph. The system additionally includes a query manager for providing a query interface between applications and the system and for forming graph data representative of a complete graph from at least the base graph data and the update graph data, if any. The system also includes a graph computer for processing the sampled portions using batch-type computations to generate approximate results for graph-based queries.”

The patent application was filed on August 20, 2015 (14/831,792).
