Portfolio of Solutions With Newest Patent

Company's 88th Patent Allows Organizations to Make the Most of IT Investments

LONGMONT, Colo., Jan. 29, 2013 (GLOBE NEWSWIRE) -- Dot Hill Systems Corp.
(Nasdaq:HILL), a leading provider of SAN storage solutions, announced it has
patented a method for maximizing RAID storage system performance, enabling
organizations to fine-tune IT infrastructure to better meet business
requirements. The innovation improves read and write performance across Dot
Hill's entire portfolio of storage solutions used by OEMs, media &
entertainment (M&E) organizations and enterprises with virtual
infrastructures.

"Providing users with a technology edge is a key initiative for Dot Hill, and
building our IP demonstrates our commitment to innovation," said Ken Day,
senior vice president of engineering, Dot Hill. "IT managers require

Dot Hill's 88^th U.S. patent, numbered 8,356,126, describes technology that

controllers with front-end coalescing, via a more precise method of data
location.

haystack."
