Nadella said Fairwater is a seamless cluster of hundreds of thousands of NVIDIA GB200s connected by fiber long enough to circle the Earth 4.5 times, delivering 10x the performance of today’s fastest supercomputer for AI training and inference.

He stated the system integrates compute, network, and storage so a single job can run at exponential scale across thousands of GPUs from day one, with liquid-cooled closed-loop design requiring zero water for operations after construction and all energy consumption matched with renewable sources.

Nadella added that multiple identical Fairwater datacenters are under construction across the US, with AI infrastructure already deployed in over 100 datacenters across more than 70 regions worldwide.
