Data-center companies face two pressing questions. First, how do they increase the density of computing power that high-performance systems need to support AI and machine learning? Second, how do data centers slash their carbon footprint in an environmentally aware market? Spanish company Submer believes it can help answer them both. With 40 clients in Europe and the US, Submer says it can cut the energy consumption of traditional air cooling and increase the viable density of high-performance computing by a factor of 10. Liquid submersion is common in the electric power-distribution infrastructure in components such as transformers, but it is rarely used for cooling IT hardware. In principle, submerging computer components is more efficient because liquids absorb more heat and take longer to heat up than air. The approach can also allow the overall system to run at higher temperatures because liquids help prevent hotspots that damage components. Obviously, it is important that liquid coolants do not conduct electricity. Although cold-plate liquid cooling is sometimes used in a closed system to cool the system chassis, immersing the whole system in liquid is almost unknown in computing. Submer was founded by Daniel Pope, a tech entrepreneur also behind Webhosting company Datahouse Internet, which he sold to Telefonica Group in 2010. He says one of the challenges to gaining acceptance in data centers was to build an immersive cooling system that could be easily managed in that environment. "The products that were out there had a very industrial approach and they really didn't look like something you'd place next to your racks. We designed a machine that is operated in a way that a data-center manager feels comfortable with." The other problem for industrial cooling liquids is compatibility with computing components – they can damage some of the plastic commons in server components. Founded in 2015, Submer has developed a dialectic fluid formula that Pope says can be manufactured anywhere in the world. Learn more from OUR FORUM.
