The true measure of tomorrow’s data centre lies not in how much compute it delivers, but in how responsibly it delivers it. The changing data centreLiquid cooling has become a major talking point in this epoch of AI data centres. Early IBM mainframes in the 1960s and Cray supercomputers used liquid cooling with great success to manage increasing computational demands. The difference today is scale; generative AI has fundamentally changed the way data centres are designed and operated. Ultimately, the future data centre must support the digital ambitions of society while respecting the natural systems that sustain it.
