This has clearly had a direct impact on other aspects related to the data centre management and maintenance procedures, such as cooling. The heat-loads generated by modern data centres to answer the ‘need of data’ are far above traditional, server-based applications and this drastically increases the costs of cooling the equipment and the space needed to operate it effectively. The point of no return Attacking the challenge of cooling in the data centre with colder and forced air is nothing more than staying in line with what the industry has been doing for the last 50 years – a typical evolution of ‘adding fuel to the fire’. And it is also a process which, like any evolution, is destined to end: data centres increasingly require higher densities (reaching 100 kW per rack will soon be normal and necessary) and it is simply not possible to think of cooling them with traditional methods (that is, by means of air). We must accept that we have already reached the point of no return. efficient cooling solutio to come and become m the not-so-distant futu experts’ forecast, acco Immersion Cooling ma is anticipated to registe 40%, during the foreca 2025), not everybody i that Immersion Cooling viable solution.

Immersion Cooling: Back to the future Liquid immersion cooling is not a new technology, it has been widely used since the 1940s to cool highvoltage transformers. In recent years, Immersion Cooling has returned to the spotlight and there is evidence that it will represent the most 22 Issue 16
