ISRs Noelke said the closed system can remove enough heat to enable data center administrators to, in some cases, almost double the amount of computing power they can put into the same space. In one 25,000-square-foot data center, a user was able to increase the compute density from 2,680 servers to 4,680 servers without significantly increasing power costs, he said.The results so far have been positive, said Leonard Ruff, an associate principal with the Seattle company. "You can decrease the power needed for mechanical systems significantly, because you can bypass a lot of the cooling" needed in the data center, Ruff said. Because the SprayCool is a closed system, and the water needed to recondense the vapor doesnt need to be chilled, users potentially could see a 30 percent reduction in the amount of power needed to run air-conditioning units, Ruff said. It also will enable users to grow the amount of compute capacity in their existing data centers. Ruff said there will be some resistance among data center administrators to adopt such new technology but added that many soon will have no choice. "Every IT manager is trying to squeeze as much processing capacity into every square inch of space as possible," he said. "The problem is that is comes at a cost, and that cost is heat. We cant continue to cool [these new systems] with only [the] traditional air-cooling technology that weve been using." Noelke said the SprayCool products currently can be used on the PowerEdge 1850 and 1425 systems from Dell, the eServer x326 and x336 from IBM and HPs ProLiant DL360, DL145 and DL140. ISR is hoping to sell the SprayCool products as options through OEMs and the channel. ISR also is looking to grow its product portfolio. Later in 2006, the company will begin adding other hot-running server components to the list that can be cooled by the M-Series products, including memory components, graphics cards and power supplies, as well as developing ways to bring liquid cooling capabilities to the rack level, Noelke said. In addition, the company will bring its G-Series products to the commercial space. The G-Series technology is a completely enclosed cooling system for blade server systems, with cooling targeted at the entire system.

Callison, an architectural firm with a data center design business, has been testing the SprayCool technology by using it with an HP ProLiant system for several months and also has done some case studies with the products.
