Microsoft is leveraging technology from submarines and working with pioneers in marine energy for the second phase of its moonshot to develop self-sufficient underwater datacenters that can deliver lightning-quick cloud services to coastal cities. An experimental, shipping-container-size prototype is processing workloads on the seafloor near Scotland’s Orkney Islands, Microsoft announced today.
The deployment of the Northern Isles datacenter at the European Marine Energy Centre marks a milestone in Microsoft’s Project Natick, a years-long research effort to investigate manufacturing and operating environmentally sustainable, prepackaged datacenter units that can be ordered to size, rapidly deployed and left to operate lights out on the seafloor for years.
“That is kind of a crazy set of demands to make,” said Peter Lee, corporate vice president of Microsoft AI and Research, who leads the New Experiences and Technologies, or NExT, group. “Natick is trying to get there.”
Lee’s group pursues what Microsoft CEO Satya Nadella has called “relevant moonshots” with the potential to transform the core of Microsoft’s business and the computer technology industry. Project Natick is an out-of-the-box idea to accommodate exponential growth in demand for cloud computing infrastructure near population centers.
More than half of the world’s population lives within about 120 miles of the coast. By putting datacenters in bodies of water near coastal cities, data would have a short distance to travel to reach coastal communities, leading to fast and smooth web surfing, video streaming and game playing as well as authentic experiences for AI-driven technologies.
“For true delivery of AI, we are really cloud dependent today,” said Lee. “If we can be within one internet hop of everyone, then it not only benefits our products, but also the products our customers serve.”
From France to Scotland
Project Natick’s 40-foot long Northern Isles datacenter is loaded with 12 racks containing a total of 864 servers and associated cooling system infrastructure. The datacenter was assembled and tested in France and shipped on a flatbed truck to Scotland where it was attached to a ballast-filled triangular base for deployment on the seabed.
On deployment day, the winds were calm and seas flat under a thick coat of fog. “For us, it was perfect weather,” said Ben Cutler, a project manager in the special projects group within Microsoft’s research organization who leads the Project Natick team.
The datacenter was towed out to sea partially submerged and cradled by winches and cranes between the pontoons of an industrial catamaran-like gantry barge. At the deployment site, a remotely operated vehicle retrieved a cable containing the fiber optic and power wiring from the seafloor and brought it to the surface where it was checked and attached to the datacenter, and the datacenter powered on.
Cutler said there were sighs of relief as these risks were eliminated. As if on cue, the last wisps of fog lifted.
The most complex task of the day was the foot-by-foot lowering of the datacenter and cable 117 feet to the rock slab seafloor. The marine crew used 10 winches, a crane, a gantry barge and a remotely operated vehicle that accompanied the datacenter on its journey.
“The most joyful moment of the day was when the datacenter finally slipped beneath the surface on its slow, carefully scripted journey,” said Cutler. Once the datacenter made it to the seafloor, the shackles were released, winch cables hauled to the surface and operational control of the Northern Isles passed to the shore station.
Everything learned from the deployment – and operations over the next year and eventual recovery – will allow the researchers to measure their expectations against the reality of operating underwater datacenters in the real world.
Powered by renewable energy
The Northern Isles is a chapter in the continuing story of Project Natick, one that tells a tale about researching whether it’s possible to use the existing logistics supply chain to ship and rapidly deploy modular datacenters anywhere in the world, even in the roughest patches of sea.
“We know if we can put something in here and it survives, we are good for just about any place we want to go,” said Cutler.
The European Marine Energy Centre is a test site for experimental tidal turbines and wave energy converters that generate electricity from the movement of seawater. Tidal currents there travel up to nine miles per hour at peak intensity and the sea surface regularly roils with 10-foot waves that whip up to more than 60 feet in stormy conditions.
Onshore, wind turbines sprout from farmers’ rolling fields and solar panels adorn roofs of centuries-old homes, generating more than enough electricity to supply the islands’ 10,000 residents with 100 percent renewable energy. A cable from the Orkney Island grid sends electricity to the datacenter, which requires just under a quarter of a megawatt of power when operating at full capacity.
