Trends in data center cooling have changed dramatically over the past few years. Outmoded ?maximum cooling? approaches have given way to more efficient heat-rejection systems. Utilizing sophisticated economizer technologies, modern cooling systems are not only reducing energy costs, but are also operating far more efficiently, and are highly reliable.

Other recent improvements in data center cooling technology have spawned different perspectives in addressing the use of chilled water vs pumped refrigerant vs air-cooling. Depending on the business needs, a company?s budget, and the geography, current cooling approaches may introduce waterless systems that may prove more suitable than say, a chilled water system.

The days of keeping the data center below 55 degrees are likely over. Old standards are being challenged and, in many cases, operating a warmer data center will be just as reliable, more efficient, and it will certainly be cheaper.  And that will make your data center much ?cooler? than it used to be.
