Scope

"Recent trends toward increased equipment power density in data centers can result in significant thermal stress@ with the undesirable side effects of decreased equipment availability@ wasted floor space@ and inefficient cooling system operation. In response to these concerns@ manufacturers identified the need to provide standardization across the industry@ and in 1998 a Thermal Management Consortium was formed. This was followed in 2002 by the creation of a new ASHRAE Technical Group to help bridge the gap between equipment manufacturers and facility designers and operators. ""Thermal Guidelines for Data Processing Environments"" the first publication of TC9.9@ is discussed in this paper@ along with a historical perspective leading up to the publication and discussion of issues that will define the roadmap for future ASHME activities in this field."
