Linus’ previous calculating world record was 32 million digits of Pi calculated in 30 minutes. Meanwhile, the standing record was just over 200 trillion.

In order to fit the full calculation for Pi that Linus wanted to do, he’d need 11.7 billion pages worth of number storage to pull off the feat. So, he built a server farm with enough data storage to keep track of the calculation.

With 2.2 petabytes of storage, around 2,200 terabytes of lightning-fast storage, he was able to achieve the record. That’s where the real expense came in along with the server setup and raw computing power to get through the sheer amount of calculations they’d have to do.

The calculation took 190 days and was sustained through multiple power outages and the cooling for their server room failing, but, after months of it running and around $6300 USD in power consumption costs, the record was broken.
