"We're creating a lab that can monitor itself, manage itself through advanced analytics and control itself ... to find out what is the most efficient way to do things," says Doug Oathout, VP of green IT at HP.
While the goal of the research is to develop a data center that is self-sustaining, the facility will not be able to generate its own power. "But that's what the research will lead to," says Oathout. The data center will still depend on power from the local electric utility but will deploy new technology to use that electricity wisely.
The facility will create what HP calls a "microgrid" for managing the electricity from the utility and a corresponding microgrid for cooling to offset the heat generated by the servers, he says. The cooling microgrid is based on a process called a water side economizer, a form of evaporate cooling. In Colorado's hot and dry summers, water sprayed into the air evaporates and cools the water inside a compressor tank. That water is then pumped into a heat exchanger that creates cool air that flows into the data center. "It doesn't need any energy to do this," Oathout said.
The data center also uses an "air side economizer," which basically pumps in cool air in the fall and cold air in the winter from outside to cool the servers. In Colorado's cold, snowy winters, 76 percent of the hot air in the data center can be cooled by fresh air, 56 percent in the fall, but only 25 percent in the summer.
