Hot Air Isolation Enables Air Cooling in High Density Data Centers

"The first paragraph of an article on cooling data centers will give away its age. When I first started writing and speaking about thermal management in data centers some seven to eight years ago, I always felt compelled to open with a review of the heat density forecasts from ASHRAE and the Uptime Institute with the motive of scaring the reader or listener into staying with me to the end. Such rhetorical ploys are no longer necessary, so instead I can get right to the point: Contrary to some well-intentioned and much self-serving sound and fury, air is quite capable of dissipating heat loads in excess of 30 kW per rack, and doing it quite economically. That will be good news to the 92% of data center managers who have not yet tried liquid cooling and the 65% who said they would never use liquid cooling in their data centers, according to a SearchDataCenter.com survey.¹"
