Liquid-Cooled Switching Doubles AI Network Bandwidth Per Rack
CoreWeave, Tuesday, July 21st, 2026
CoreWeave deploys NVIDIA's fully liquid-cooled Spectrum-X switch, doubling AI switching capacity per rack.
CoreWeave deployed the NVIDIA Spectrum-X SN6600-LD, a fully liquid-cooled Ethernet switch delivering 102.4 Tb/s of switching capacity, as part of its Vera Rubin NVL72 infrastructure.
This enables 1.64 Pb/s of switching capacity per rack, double the previous air-cooled performance, while improving power efficiency 30% and cutting rack footprint 62.5%.
It reflects CoreWeave's unified approach to integrating compute, networking, and cooling into one software-defined layer managed via its Mission Control platform.
