Data Center Server Immersion Cooling Is No Longer Just For Hyperscalers Or HPCs, RNT Rausch Wants To Extend It To Businesses Of All Sizes


German server and storage solutions provider RNT Rausch has announced that it has partnered with Submer Technologies to provide customers of all sizes with the latest server immersion cooling technologies. This partnership keeps RNT servers and BigFoot storage systems (a set of tools that enable massive data storage and analysis) cool in a sustainable and environmentally friendly way. RNT aims to democratize immersion cooling to reduce the environmental impacts of current energy- and water-greedy cooling systems.

The partnership between Submer and RNT allows companies of all sizes to deploy their data center virtually anywhere. A small space is enough to accommodate solutions and there is no need to install air conditioning units to cool servers or expensive and sophisticated fire extinguishing systems. The room will require simple access control for one person, as well as occasional power adjustments to keep it safe. This cooling solution stores devices in one place, reducing space requirements and cost of ownership and resources.

Immersion cooling is a computer cooling practice in which computer components and other electronic devices, including entire servers and storage devices, are immersed in a thermally conductive, but electrically insulating coolant or dielectric fluid. Heat is removed from the system by circulating relatively cold liquid in direct contact with the heated components, then circulating the heated liquid through cold heat exchangers. The system is currently not very popular, but things may change in the future.

In fact, data centers are expected to drive growth due to the growing demand for energy -efficient and economical cooling solutions. Deep learning, machine learning, Internet of Things (IoT), smart cities, artificial intelligence (AI), cloud computing and blockchain are examples of emerging technologies that require the processing of big data, which requires more computing power. According to industry experts, immersion cooling is capable of handling higher thermal loads than air cooling.

Therefore, it should increase immersion cooling sales. There are two types of immersion cooling, including single-phase immersion cooling and two-phase immersion cooling. Furthermore, recent studies on the immersion cooling market report that the most successful players currently are: Fujitsu Ltd, Dug Technology, Submer, ExaScaler, Inc., Liquid Stack, Midas Green Technologies, Asperitas, LiquidCool Solutions. Submer provides active single-phase immersion cooling for servers and storage systems.

RNT’s collaboration with Submer sees the application of single-phase immersion cooling to the Tormenta Varioscaler server portfolio of RNT and BigFoot storage systems. Single-phase immersion cooling means that the coolant never changes state (i.e., it does not evaporate into a gas) and it is simply pumped through a heat exchanger to transfer heat to a water cooling circuit. According to RNT and Submer, traditional cooling methods require high costs in terms of energy and water consumption.

For many organizations, this means wasting money for these resources, which also take up a lot of space. The same company states that an air-cooled environment requires up to 10 times more space than environments built using immersion cooling. This partnership enables RNT Rausch and Submer to offer a complete and sustainable turnkey HPC solution, specifically designed for customer needs. “Partnerships like this are critical to the future of the industry,” said Daniel Pope, CEO and co-founder of Submer.

In addition, HPC deployments are not the only ones that require liquid cooling. According to Cisco, the next generation of processors from AMD and Intel is expected to achieve 400W of power consumption, while high-end GPUs are already here and showing no signs of stopping. Dattatri Mattur, senior director of engineering for Cisco’s Cloud and Compute business, said this means air cooling will soon be inadequate, even for traditional servers, and many data centers will need to use some form of liquid cooling.

Furthermore, Submer and RNT believe that immersion cooling will help save the plant. Immersion cooled data centers are extremely energy efficient. Companies with immersion cooling data centers can reuse not only water from pods, but also heat to reduce waste. “It’s also possible to cool more pods in liquid than a rack, which reduces energy costs and, therefore, the company’s carbon footprint,” they explain.

“Submerged cooling has many benefits, not only in saving space, but also energy, and helps companies reduce their carbon footprint and be as sustainable as possible,” they added. RNT and Submer will jointly showcase at ISC 2022 from May 29 to June 2 to showcase the solution to the HPC community and demonstrate how RNT’s BigFoot storage system speeds up data processing without causing a bottleneck to a pool of uncontrolled driver.

While Submer and RNT are betting on single-phase immersion cooling, other players in the industry are more inclined to the two-phase technique. In April 2021, Microsoft announced that it was exploring a new way to cool data center servers by dipping them in liquid baths. Server racks are immersed in a non-conductive fluorocarbon liquid designed especially for the occasion. The liquid, with a boiling point of less than 122 degrees Fahrenheit (or 50 degrees Celsius), dissipates heat by directly flooding the parts.

Microsoft is currently conducting the first tests at a data center located on the east bank of the Columbia River. The company says it is the first cloud computing service provider to test it in production. “We are the first cloud provider to use two-stage immersion cooling in a production environment,” said Husam Alissa, senior hardware engineer with Microsoft’s advanced data center development team in Redmond, State from Washington. The company believes that immersion cooling is the future.

The production deployment of two-stage immersion cooling is the next step in Microsoft’s long-term plan to meet the need for faster, more powerful computers in data centers at a time when reliable development in air-cooled computers has slowed. chips, the company says.
