AI is transforming the data centre into a tightly coupled system in which compute, power, liquid cooling, heat rejection, controls and digital twins can no longer be designed independently. Hosted by the Sustainable Tropical Data Centre Testbed (STDCT), this panel brings together leaders across thermal management, electrical infrastructure, digital engineering, automation and data-centre design to examine where the real deployment risks now reside: at the interfaces between systems. The discussion will explore how integrated design, standards, simulation, testbeds and system-level validation can accelerate the deployment of efficient, resilient and scalable AI data centres.
