The white paper provides an in-depth analysis of challenges faced by high-density cabinets in AIDCs in terms of cooling, power supply and distribution, floor height, and load-bearing capacity, and offers design suggestions across four key dimensions of architectural structure, power supply and distribution, cooling, and integrated cabling, providing multiple reference design solutions for AIDCs based on different power densities. At Huawei Connect 2025, Huawei Digital Power demonstrated its innovative green and low-carbon solutions on F03, Hall 2, SWEECC across three key scenarios: efficient power consumption, electrification, and low-carbon power generation.
