CARLSBAD, CA -- Dot Hill Systems Corp., (NYSE: HIL) a leading provider of storage networking solutions, today announced that its SANnet® 7100 and 3300 series storage systems have been certified by an independent laboratory on a variety of United States Department of Defense (DOD) military ruggedization standards known as MIL-STD-810F. MIL-STD-810F focuses on environmental engineering issues and requires products to pass various laboratory tests to ensure that military equipment operates in worldwide environments. Many government agencies and prime defense contractors require the products they use to be "mil-spec" certified. To achieve MIL-STD-801F certification, products must undergo rigorous environmental testing by an independent laboratory. Dot Hill's SANnet systems passed the following environmental tests: altitude, high and low temperature, humidity, functional shock, salt fog, transportation vibration and watercraft and marine vehicles. Dot Hill Chief Technology Officer Dana Kammersgard said, "We were confident that our SANnet products would pass these rigid military specifications since they are already NEBS (Network Equipment Building Systems) Level 3 certified for our telecommunications customers. Dot Hill has a reputation for providing highly reliable and survivable products and has a successful track record in a wide variety of military programs and government agencies. SANnet was designed to be both rugged and compact, two factors that are of particular importance for our military and telecommunications customers." For more information visit www.dothill.com
