ASHRAE works to expand datacom environmental classes
March 12, 2011
ASHRAE continues to widen the temperature and humidity ranges for servers through a soon-to-be-published third edition of the book, “Thermal Guidelines for Data Processing Environments”. The first edition was published in 2004 and, according to ASHRAE’s Don Beaty, created the first global, vendor-neutral environmental spec for data centres.

The third edition will enable compressorless cooling (all cooling through economizers) in many applications. “Different locations, applications and business philosophies make it ineffective to force all equipment to be capable of the same high temperature tolerance (in some cases higher thresholds would negatively impact the return on investment),” Beaty said. “To address this, the third edition creates multiple server classes and, therefore, provides freedom of choice. This is particularly important since the thermal guidelines are used throughout the world.”
