Microsoft’s Underwater Data Centre Resurfaces After Two Years

Microsoft’s underwater data centre resurfaces after two years

Two years ago, Microsoft sank a data centre off the coast of Orkney in a wild experiment. That data centre has now been retrieved from the ocean floor, and Microsoft researchers are assessing how it has performed, and what they can learn from it about energy efficiency. Their first conclusion is that the cylinder packed with servers had a lower failure rate than a conventional data centre.

That compares very well with a conventional data centre. The team is speculating that the greater reliability may be connected to the fact that there were no humans on board, and that nitrogen rather than oxygen was pumped into the capsule.
