AWS is also introducing liquid cooling systems to keep the most powerful chips from the likes of Nvidia Corp. running smoothly. Such chips can’t be effectively cooled by fans alone.
Amazon.com Inc.’s cloud unit is rolling out components it says will make data centres run more efficiently, a move that could help address the growing strain power-hungry server farms are putting on the electrical grid.
Amazon Web Services’s (AWS) latest data centre designs include more efficient cooling, renewable diesel for backup generators and an optimised server rack layout that reduces the amount of power left unused. Some components are already deployed, while others will arrive in new data centres as they come online, the company said on Monday.
