Immersion liquid cooling specialist Asperitas, a company collaborating with Shell for its immersion cooling fluid, has won an immersion cooling deal with French Bank Crédit Agricole. The Asperitas technology would enable the bank’s Tier 4 data centers to significantly reduce their energy costs and environmental footprint.

At the same time, the Asperitas technology would help Crédit Agricole prepare for a near future with more compute driven applications and situations where high-density solutions are required.

In 2018, a pilot project with Asperitas Immersed Computing was installed for Credit Agricole, during which the technology was validated. It met all their Tier 4 data center and enterprise standards, therefore being qualified to adopt at their core data centers.

“The flexibility and simplicity of the AIC24 modules make it a highly scalable data center cooling solution, without for Crédit Agricole having to change their environmental infrastructure,” said Rolf Brink, CEO of Asperitas.

The pilot project of the Asperitas solution at the Greenfield data center, the largest within Crédit Agricole, managed more than 40% of the bank workload in Chartres. The module was exposed to numerous weather fluctuations and performed exceptionally, demonstrated by the energy efficiency indicator PUE “improving from 1.4 to 1.03 in the winter and 1.04 during a heat wave.” Based on this success, the next step of the project is to now install multiple Asperitas modules in two data centers, taking up a potential 150 square meters of floor space, versus the 6,000 square meters of white space currently.

“The immersion cooling solution provided by Asperitas allows us to increase the density of our data center without major work,” said Jean Buet, Senior Officer, Head of Data Centers, Crédit Agricole. “We can thus offer our customer a high thermal density solution that meets both their growing demand and the new technological challenges that appear with the new generation of IT equipment. After two years of observation in production, we decided to deploy this solution.”

The Asperitas AIC24 solution with its Immersed Computing technology will meet the demand for high density compute on a system and server level for Crédit Agricole. The system makes use of the natural convection driven fluid circulation within. This unique approach would enable immersion cooling to be both climate independent (free cooling up to 48 degrees Celsius) and fully heat reuse ready (more than 98% energy transformed into hot water).

Making use of the Shell Immersion Cooling Fluid product, produced by the gas-to-liquids (GTL) technology from development partner Shell, the Asperitas AIC24 solution is suitable for the most demanding and enterprise level data centers. It would allow for efficient cooling regardless of the data center’s external environment.

“We are very excited with this success. Shell is committed to working with our partners and customers to develop solutions that can help them decarbonize,” said Sundeep Kamath, Global Marketing Manager for Process Oils, Shell. “Data centers today consume about 1% of global energy demand and this is only expected to grow with exponential amounts of data being generated. This innovative solution would offer the best of all worlds – increased compute performance, lower costs, and a lower CO2 footprint. Shell is deploying this technology for our own high-performance computing and we are very happy to see a leading bank like Crédit Agricole has also chosen this innovative, award winning solution.”

The multiple module installation is scheduled for before the end of 2020, with Asperitas working alongside Dell Technologies to provide integrated compute solutions.

“I am delighted that Crédit Agricole, a leading global enterprise with high requirements for their infrastructure, has chosen Asperitas to support their data center scale-up,” said Rolf Brink, CEO of Asperitas. “The flexibility and simplicity of the AIC24 modules make it a highly scalable solution, without having to change the environmental infrastructure, so this outcome enables Crédit Agricole’s next step in development to be quite straight-forward. Having multiple AIC24 modules in the France site will make a huge impact on their data center performance, efficiency and sustainability, proving them to be a true ambassador of immersion cooling.”
