Dot Hill Storage Innovation Reduces Power Requirements While Safeguarding Data

                Innovation Described in Company's 91st Patent

         Protects Data and Preserves Cache in the Event of Power Loss

LONGMONT, Colo., Sept. 12, 2013 (GLOBE NEWSWIRE) --Dot Hill Systems Corp.
(Nasdaq:HILL), a leading provider of SAN storage solutions, today announced it
has patented a method for safeguarding data and preserving cache in the event
of main power loss.

Critical information stored in volatile memory, including cached write data
and metadata, must be preserved in the event of main power loss. Volatile
memory stores this data as long as the memory is powered, but does not retain
the data if main power is lost for any reason. When main power loss occurs,
valuable data is transferred from volatile memory to the non-volatile memory
of the computer memory system. This transfer of data is referred to as a
memory flush operation.

Dot Hill's 91st U.S. patent, numbered 8,510,598, provides a method to reduce
power usage in computer memory systems during volatile memory flush
operations.This innovation reduces power required for a memory flush
operation by selectively providing power to certain computer components at
certain times, and not to others. By reducing this power requirement, a
smaller power source such as a supercapacitor may be used by the computer
memory system.

"Dot Hill AssuredSAN and AssuredSAN Pro systems are engineered to deliver
exceptional reliability and 99.999 percent data availability," said Ken Day,
chief technology officer, Dot Hill. "IT managers are concerned with the
preservation of all data within the storage system, including the state of the
cache memory in the event of a failure. This latest innovation allows recovery
of all stored data if the main power is lost. As Dot Hill grows closer to the
100-patent mark, we continue to deliver innovation that truly matters to

solutions stands on three pillars of innovation which, when combined, provide
a complete platform for addressing customers' storage needs. These pillars
include software, platforms and systems, which combine to create advanced SAN
