The road to current datacenters
As energy demand from datacenters was a rising issue, the interest in immersive cooling regained by the end of the 2000's,early 2010's. Multiple companies, including IBM, Microsoft, Google, Facebook, etc are working on it. The most common form is open-bath immersive cooling, where a bath is filled with liquid and the server components are hung into it vertically. Technically a great solutions, but not very practical.
As datacenters around the world, especially the multi-tenant ones, won't allow open bath immersive cooling on their datafloors, popularity remains behind. Within the Open Compute Project, a knowledge sharing and combination of stakeholder organisation aimed to reduce datacenter cost, energy hunger and increase efficieny, a lot of work is being done. Needless to say, iXora is joining the Open Compute Project.
