Microsoft’s subsea data center experiment increases reliability eightfold



[ad_1]

In 2018, Microsoft dumped a data center into the sea, off the coast of Scotland’s Orkney Islands. This was part of an experiment to see if it was a better way to run data centers. The company recently published the result of its experiment, saying that an underwater data center is a good idea.

The company explains that on the ground, data centers are prone to failure in all sorts of ways. From corrosion due to exposure to oxygen and moisture, temperature fluctuations, and even human collisions. But dumping data centers, sealed with nitrogen inside a large metal tube, into the sea solves all these problems.

As a result, Microsoft says the subsea data centers were eight times more reliable than similar ones on land. But it has to be that way, because repairing a data center that is sealed in an airtight container under the sea can be a hassle, to say the least.

With the success of this experiment, Microsoft says it is working on a couple of things. One is to replicate this type of low failure rate in terrestrial data centers. Another is to expand these subsea data centers, which may involve linking a dozen of them.
