SpaceX is developing the Kessel custom rack system with 72 Nvidia GPUs
SpaceX and xAI are reportedly working on a custom Nvidia-based rack system named Kessel that features an 84-layer printed circuit board instead of conventional cables.
According to reports, SpaceX and xAI are developing a custom rack-scale AI system codenamed Kessel. The design keeps the core configuration of Nvidia's Vera Rubin NVL72 platform, utilizing 36 Vera CPUs, 72 Rubin GPUs, and nine NVLink switch trays. Instead of conventional cable assemblies, Kessel replaces them with an 84-layer printed circuit board midplane. The system is intended for terrestrial and orbital data center deployments, giving Elon Musk's company independent component sourcing and greater hardware supply chain control.
