Microsoft Ends 'Project Natick' Underwater Data Center Experiment Despite Success
Microsoft has decided to end its Project Natick experiment, which involved submerging a datacenter capsule 120 miles off the coast of Scotland to explore the feasibility of deploying underwater datacenters. TechSpot's Rob Thubron reports: Project Natick's origins stretch all the way back to 2013. Following a three-month trial in the Pacific, a submersible data center capsule was deployed 120 miles off the coast of Scotland in 2018. It was brought back to the surface in 2020, offering what were said to be promising results. Microsoft lost six of the 855 servers that were in the capsule during its time underwater. In a comparison experiment being run simultaneously on dry land, it lost eight out of 135 servers. Microsoft noted that the constant temperature stability of the external seawater was a factor in the experiment's success. It also highlighted how the data center was filled with inert nitrogen gas that protected the servers, as opposed to the reactive oxygen gas in the land data center. Despite everything going so well, Microsoft is discontinuing Project Natick. "I'm not building subsea data centers anywhere in the world," Noelle Walsh, the head of the company's Cloud Operations + Innovation (CO+I) division, told DatacenterDynamics. "My team worked on it, and it worked. We learned a lot about operations below sea level and vibration and impacts on the server. So we'll apply those learnings to other cases," Walsh added. Microsoft also patented a high-pressure data center in 2019 and an artificial reef data center in 2017, but it seems the company is putting resources into traditional builds for now. "I would say now we're getting more focused," Walsh said. "We like to do R&D and try things out, and you learn something here and it may fly over there. But I'd say now, it's very focused." "While we don't currently have data centers in the water, we will continue to use Project Natick as a research platform to explore, test, and validate new concepts around data center reliability and sustainability, for example with liquid immersion."
