The NVIDIA Rubin platform represents a fundamental shift from accelerator-centric design to rack-scale AI factory architectures using co-design to tightly integrate CPUs, GPUs, DPUs, NVLink fabrics, and high-speed Spectrum-X Ethernet networking. BlueField-4 extends this architecture by offloading networking, storage, security, and infrastructure services from host CPUs, creating a programmable operating layer for AI at scale. The BlueField-4 data storage processor fuels a new tier of fast, efficient KV cach ...
