Choosing System Architecture and Cooling Fluid for High Heat Density Cooling Solutions
According to a report by the American Society of Mechanical Engineers, by 2011, computer and communications rack heat loads are projected to reach 30 kW with heat load densities of more than 500 W/ft2. Because availability is so dependent on temperature control in critical spaces, it is vital to explore cooling fluid (water vs. refrigerant) and system architecture (open vs. closed) options, as well as supplemental cooling technologies for specific data center applications. This paper walks IT and data center managers through increasing cooling efficiency through tactics like cable management and rack arrangement, and implementing supplemental cooling where appropriate. Reducing high heat densities in the data center can help to avoid problems like high soft error rates, erratic or unrepeatable information, and outright hardware failures.
