NVIDIA AI Factory Certification: Liquid Cooling CDU Barriers and LG's 600kW Breakthrough

NVIDIA AI Factory certification is becoming a "capability passport" for liquid cooling infrastructure. LG Electronics' 600kW-class CDU obtaining this certification signals that competition in the liquid cooling supply chain has shifted from "is it usable?" to "do you have the cert?" On the surface, this looks like standard vendor news, but underneath it reflects two key issues: first, the power density of liquid cooling CDUs is skyrocketing; second, the certification itself is becoming a technical barrier.
