Google: data center managed via ai uses on average 30 percent less energy

Google reports that a few months ago it was transferred to a system that, based on artificial intelligence, manages the cooling of its data centers without the intervention of people. Until now, this would have yielded an average energy saving of 30 percent.

DeepMind, a sister company of Google, writes in a blog post that the AI ​​system every five minutes a snapshot of thousands of sensors from a whole data center. It then analyzes how it can minimize the energy consumption of the data center by taking certain actions that are defined by safety considerations. On a graph, this ai control mode has been in use for about nine months. The energy saving of an average of 30 percent would have been realized in that time. Further improvement would be possible due to more and more data.

The company does not reveal which data centers control is left entirely to artificial intelligence, but speaks of “some Google data centers” where services like YouYube, Gmail and Search are hosted. The system uses a degree of uncertainty, so that it takes a certain action only if it is certain that it is the right one. In addition, additional checks are carried out to determine whether the action falls within the applicable safety standards. Finally, it is always possible to return control to traditional systems.

The idea of ​​leaving the control entirely to AI came from the managers of the data centers themselves, who already used the system to make recommendations. However, following these recommendations would require too much effort and supervision. DeepMind does not explain which actions the system can take exactly. Dan Fuenffinger, one of the Google data center employees, cites an example: “It was fantastic to see how the AI ​​learned to use the winter weather to produce colder water than normal, which reduced the energy needed for cooling. . ”
