Pi, an irrational number, has no end. But computer engineers are still chasing the eternal string of decimal places deep into the unknown. Recently, technology media company StorageReview set an incredible new record by calculating 314 trillion digits of Pi on a single Dell PowerEdge R7725 server that ran continuously for almost four months.
This result shows that in modern Pi calculations, the real battle is no longer just about processor speed, but also about storage capacity and efficiency. StorageReview’s Dell PowerEdge R7725 server had 1.5 terabytes of memory to run the job.

Historical pi records have jumped rapidly over the past few years, from Google Cloud’s 100 trillion digits in 2022 to StorageReview’s own 105 trillion digits and 202 trillion digits in 2024. In April 2025, Linus Media Group and Kioxia dethroned Pi by calculating it to 300 trillion digits, but StorageReview regained the record in November 2025.
The results were announced to coincide with Pi Day on March 14 (or 3/14), named after the famous first three digits of Pi (3.14). The day was a light-hearted tribute to mathematics, featuring pie jokes, pie slices, classroom contests, and a never-ending public frenzy over numbers.
Why pi is important
Pi is an important constant in mathematics that connects the circumference of every circle to its diameter. It shows up in geometry, physics, engineering, and statistics, and in everything from waves and trajectories to bridges, buildings, and computer models. Most people encounter pi in school as a simplified number used to find area and circumference. But for engineers and scientists, it’s a building block that helps explain how the physical world works.
Pi is considered an irrational number because it cannot be written as a simple fraction of two integers. Its decimal format never ends and never settles into a repeating pattern. Mathematician Johann Lambert was the first to prove that pi is an irrational number in 1761, showing that there is no fraction exactly equal to the ratio of a circle’s circumference to its diameter. Therefore, pi is an exact number, but its decimal expansion is infinite.
All these numbers are not strictly necessary for accurate calculations. NASA typically stops its most accurate calculations about space at 16 digits. Still, researchers are challenged to calculate pi to ever more decimal places for a variety of reasons. It’s a way to test the limits of your computer, storage, and software. This is because running PI at scale can reveal weaknesses in your hardware more than many standard benchmarks. Calculating pi also helps researchers improve algorithms for handling other large-scale calculations.
And, of course, he has the reputation of being the person who calculated pi to the decimal place. To achieve the mind-boggling 314 trillion digits pi result, StorageReview provided approximately 280 GB/s of bandwidth to Dell’s servers to handle the huge stream of intermediate computations required to run such a large scale.
“If someone wants to take the record, we want them to take care of it all: order of magnitude increases, lower power consumption, shorter operating times, and the same zero-downtime reliability,” the company said in a statement. “Until then, this will be our efficiency benchmark.”
