SpaceX is developing Kessel, a custom Vera Rubin NVL72 rack intended to reduce its reliance on Nvidia components. According to Sina Finance, citing SemiAnalysis, Kessel replaces the NVLink cable box with a passive PCB midplane while retaining Oberon's 72 GPU packages, 18 compute trays and nine switch trays, arranged back-to-back around the midplane. A smaller version of Kyber, Kessel has a smaller vertical scaling domain and is designed for both ground and orbital deployment. It uses an 84-layer M10 midplane, compared with the 156-layer M9 midplane planned for the earlier Kyber design; fewer layers make manufacturing more feasible, but Kessel requires higher-grade materials. SpaceX plans to buy chip packages directly from Nvidia and source the other components itself, bypassing Nvidia's L6 compute board. The approach would give SpaceX greater autonomy in supplier selection and component procurement.
