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
800 Gb/sBlueField-4 DPU throughput (STX storage architecture), ~6x BlueField-3 compute; WEKA/VAST/DDN platforms
800 Gb/sBlueField-4 DPU throughput; 64 Arm cores, ~6x BlueField-3 compute; zero-trust east-west enforcement at line rate
up to 1.6 Tb/sNVIDIA ConnectX-9 SuperNIC bandwidth (Rubin generation) — double ConnectX-8's 800 Gb/s; BlueField-4 (integrates a CX-9) ships at 800 Gb/s, double BlueField-3
