Artificial Intelligence demands infrastructures capable of handling huge thermal loads. Rittal presents its In-Row direct liquid cooling (DLC) solution, capable of dissipating up to 1 MW in rack format. Through the success story of the GSI Helmholtz Centre and its Green IT Cube Data Center, it will be shown how this technology enables AI applications to be operated efficiently and sustainably. The collaboration with the startup etalytics and the use of digital twins optimize energy consumption, setting a new standard for the data centers of the future.
