Dot Hill Assigned 106th U.S. Patent

Dot Hill Systems Corp. has been awarded a patent that provides more efficient management of read-cache operations.

AssuredSAN 3000 Series

The patented technology is used by the storage controller to intelligently optimize cache memory, resulting in lower than average data read times compared to traditional storage controllers. The technology is an integral component of RealStor, company’s real-time storage OS, and is available in AssuredSAN 3004, 4004 and 6004 hybrid storage arrays.

“The Internet of Things and rise of real-time, read-intensive computing has created a need for storage technologies that can quickly and intelligently manage growing data traffic workloads,” said Ken Day, CTO, Dot Hill. “Our patented RealStor technology is core to meeting these demands with greater predictive intelligence. Recent test results published by Demartek illustrate the performance advantage of our hybrid storage with real-time tiering that delivers nearly 5x performance over all-HDD configurations. This demonstrates our ongoing efforts to push the frontiers of storage innovation by optimizing every aspect of how we manage, profile and tier data to address changing application and end-user requirements.“

The AssuredSAN arrays are built with robust active-active HA controllers that deliver performance, reliability and resilience for demanding storage applications in server-centric applications in data centers and purpose-built vertical market applications. This patented technology optimizes read cache utilization resulting in faster access to critical data. This invention utilizes complex profiling processes to accurately predict if data currently in a read cache memory is likely to be read in the near future. If it is, the data is maintained in the read cache. If it is not, the processes replace the data least likely to be read with data in the storage devices that is most likely to be read. The result is an efficient utilization of the cache for improved performance.

The company’s 106th U.S. patent, numbered 9,053,038, joins a growing his portfolio of innovations behind its AssuredSAN hybrid arrays, delivering low-cost, high-performance storage systems to meet the challenges of IoT and third-platform computing applications.
