LONGMONT, Colo., March 26, 2015 (GLOBE NEWSWIRE) -- Dot Hill Systems Corp. (Nasdaq:HILL), a trusted supplier of innovative enterprise-class storage systems, today announced that it has been awarded a patent for a write-cache management feature that intelligently manages cache usage, allowing Dot Hill AssuredSAN® storage solutions to improve write performance by up to 100 percent in demanding storage workloads with high stream counts.

The innovation allows Dot Hill to deliver AssuredSAN storage systems that are optimized to maintain high performance for randomized sequential workloads. This is critical to Dot Hill's continued success in vertical markets such as Media & Entertainment, Video Surveillance, Telecommunications, and Oil & Gas, among others, which require storage solutions that can effectively manage multiple data streams with high throughput. Dot Hill AssuredSAN storage systems enable these businesses to edit video content faster, ingest more network traffic streams, and analyze seismic data more quickly. This unique feature establishes Dot Hill to address the need for massive ingest of sensor data as the Internet of Things becomes a reality. With more than 100 patents, Dot Hill continues its innovation leadership in storage solutions. The company's 101 st US patent numbered 8,886,880 is used in all Dot Hill AssuredSAN solutions that are based on the company's 4004 storage controller series.

Dot Hill's latest patented technology provides improved write performance to RAID arrays by intelligently managing limited memory resources in advanced storage controllers. The controller maintains statistics on what is stored in the write-data cache as well as the history of previously received writes. Based on these statistics, the controller selectively maintains or stores information to storage devices in the write-data cache, while always maintaining space for new write-data. 

"With more than 100 patents in our portfolio, this latest breakthrough really sets Dot Hill apart from the competition," said Ken Day, chief technology officer, Dot Hill. "An integral part of our latest AssuredSAN 4004 offerings, this innovation allows our storage solutions to optimize write-cache functions in a superior fashion. Since the offerings of our competitors can't provide this feature in the same way that Dot Hill does, they may copy write-data too aggressively or not aggressively enough for randomized sequential workloads. The result is reduced performance compared to Dot Hill's solutions that deliver data where customers need it, and at the speed that they need it."

Dot Hill's patent portfolio builds on the extensive intellectual property behind Dot Hill AssuredSAN and AssuredSAN Pro solutions, which deliver rock-solid, wicked-fast performance to customers and OEM partners. Dot Hill's continuous innovation benefits the company's key vertical market customers in a variety of imaging applications such as Media & Entertainment, Video Surveillance, and Digital Imaging, as well as Telecommunications, Oil & Gas, and Big Data & Analytics sectors that require high-performing storage to support demanding applications.
