What this post added

This post details the deployment of NVIDIA Spectrum-X SN6600-LD liquid-cooled Ethernet switches, highlighting their 102.4 Tb/s capacity and 1.6 Tb/s ports. It explains how this enables a non-blocking fabric for Vera Rubin NVL72 GPUs, leading to improved MFU and lower inference latency. The post also describes the integration of these switches into CoreWeave Mission Control, extending Valvey and Racky for unified thermal management and operational control, and the Rack Lifecycle Controller (RLCC) for automated rack management. It quantifies the benefits as a 100% increase in switching performance, a 62.5% reduction in rack footprint, and a 30% improvement in power efficiency.
