Dot Hill Gets Patent

CARLSBAD, Calif. -- Dot Hill Systems Corp. (Nasdaq: HILL - News), a market leader in providing flexible storage offerings and responsive service and support to OEMs and system integrators (SIs), today announced it has received a new patent related to its storage controller architecture. The patented technology is designed to increase the efficiency of networked storage environments, by improving resource allocation within the controller and processor interfaces.

The United States Patent and Trademark Office has granted the company U.S. Patent #7,277,995, entitled "Storage controller and method for performing host access control in the host interface adapter."

The patented storage controller architecture and access control method improves the way in which the LUN control functions are performed within the storage controller. By migrating this functionality from storage controller firmware, which executes on the storage controller microprocessor, to the host interface controller, this method ultimately frees up the microprocessor to perform its other functions more effectively.

Invented by Ian Robert Davies and Thomas George Wicklund, members of Dot Hill's engineering team based in Longmont, Colo., the storage controller architecture and access control method is the 21st United States Patent to be awarded to Dot Hill.

"Dot Hill's world-class engineering team continues to raise the bar for storage system performance and scalability," said Jim Kuenzel, Dot Hill's senior vice president of engineering. "The addition of the storage controller architecture and access control method patent to Dot Hill's intellectual property portfolio further validates Dot Hill's ability to leverage new and emerging technologies to provide the best mix of performance and value for our customers."
