The expansion of AI infrastructure is increasing GPU parameter sizes from 175B to 1.5T, creating immense pressure on data center thermal management. Modern high-density racks, such as the GB200 and GB300 NVL72, now require cooling capacities between 130 kW and 140 kW. TrendForce data indicates that liquid cooling adoption is expected to reach approximately 40% by 2026 as the industry shifts toward Liquid-to-Liquid (L2L) architectures to improve Power Usage Effectiveness.

While thermal management efforts have traditionally focused on compute nodes, high-radix networking switches now represent the next critical frontier for 51.2T and 102.4T platforms. UfiSpace introduces the S9331-64HO3L to meet these requirements for next-generation AI networks. This 64-port, 1.6T data center switch features Broadcom Tomahawk 6 silicon designed for high-density spine and super-spine scalability.This document provides technical insights for operators navigating the transition to liquid-cooled network infrastructure to maintain system reliability.
