Branislav Radovanovic Assigned Patent
Scalable storage architecture
By Francis Pelletier | September 18, 2015 at 2:41 pmRadovanovic, Branislav, Weatogue, CT, has been assigned a patent (9,118,698), for a “scalable data storage architecture and methods of eliminating I/O traffic bottlenecks.”
The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A SAN system has host computers, front-end SAN controllers, (FE_SAN) connected via a bus or network interconnect to back-end SAN controllers, BE_SAN, and physical disk drives connected via network interconnect to the BE_SANs to provide distributed high performance centrally managed storage. Described are hardware and software architectural solutions designed to eliminate I/O traffic bottlenecks, improve scalability, and reduce the overall cost of SAN systems. In an embodiment, the BE_SAN has firmware to recognize when, in order to support a multidisc volume, such as a RAID volume, it is configured to support, it requires access to a physical disk attached to a second BE_SAN, when such a reference is recognized it passes assess commands to the second BE_SAN. Buffer memory of each FE_SAN is mapped into application memory space to increase access speed, where multiple hosts share an LBA the BE_SAN tracks writes and invalidates the unwritten buffers.“
The patent application was filed on April 14, 2014 (14/252,268).
