DATA CENTER POWER AND COOLING TRENDS TO WATCH IN 2019
Unlike software-driven innovation, electrical and mechanical technologies advance slowly. It’s hard to code your way around the laws of physics. Meaningful breakthroughs in data center power and cooling are rare, and new technologies that do get introduced take a long time to gain critical mass on the market. Perhaps that explains why neither of the two big technological trends big vendors in the space agree will be especially visible this year is a result of recent innovation. Direct liquid cooling, which they expect to sell a lot more of in 2019, has been used in computing systems for decades; and lithium-ion batteries, which are now steadily taking over for lead-acid batteries in data center UPS systems, have been in commercial use since the early nineties.
