The big picture: In an earlier overview, Microsoft found that two-phase immersion cooling can reduce the force consumption of a server by as much as 15 percent. The company in addition , anticipates that servers within immersion tank could expertise a reduced failure rate simply because of the lack of humidity and corrosive effects of oxygen in the air.
Moore’s Law may have slowed down in recent years but the demand for considerably powerful computer hardware hasn’t had missed a beat. To keep up, hardware makers are progressively meal processors more juice with which has naturally resulted in hotter potato chips.
“Air cooling is not good enough, ” said Christian Belady, distinguished engineer and vp of Microsoft’s data town advanced development group. Its why the Redmond technology giant is now exploring the sitting in front of alternative cooling methods to circumvent overheating.
At one of its marketing information centers on the eastern bank of canada of the Columbia River, Chauhan is testing a technique recognized as two-phase immersion cooling . Inside a specially crafted steel holding tank is server hardware submerged in a non-conductive fluid from 3M that is engineered to boil at 122 degrees Fahrenheit.
When the hardware heats up, it prompts the fluid to boil. The rising vapor then comes in contact with a chilled condenser in the tank’s lid, causing the vapor to change back into a liquid and rain down into the tank, thus creating a closed-loop cooling system.
The cooling coils in the tank’s lid are connected to a separate system that transfers heat from the tank to an external cooler.
Microsoft plans to test the viability of the tech over the next several months. “This first step is about making people feel comfortable with the concept and showing we can run production workloads,” Belady said.
