CoreWeave Brings Liquid Cooled Switching to AI Networking | CoreWeave Blog

This post details the deployment of NVIDIA Spectrum-X SN6600-LD liquid-cooled Ethernet switches, which double per-rack network bandwidth to 1.64 Pb/s. It explains how this enables a non-blocking, multi-plane, multi-rail spine and leaf fabric for Vera Rubin NVL72 GPUs, reducing network latency and GPU idle time. The integration with Valvey and Racky for unified thermal management and the Rack Lifecycle Controller (RLCC) for automated rack management are also highlighted.
