BlueField
NVIDIA's DPU line, terminating tenant networking, encryption, microsegmentation, and storage initiation in hardware at the host edge — an enforcement point bought at server-spec time or never had.
Current numbers
up to 1.6 Tb/sper-GPU scale-out bandwidth on the Rubin platform — two 800 Gb/s ConnectX-9 SuperNICs per GPU, not one 1.6T NIC; double the ConnectX-8 generation; BlueField-4 (integrates a CX-9) at 800 Gb/s
64-coreBlueField-4 Arm Neoverse V2 complex (64B transistors, ~6× BF-3 compute); 128 GB LPDDR5; PCIe Gen6
800 Gb/sBlueField-4 DPU throughput (STX storage architecture), ~6x BlueField-3 compute; WEKA/VAST/DDN platforms
