3.3 Interfaces Detailed Description
3.3.1 DPU System-on-Chip (SoC)
NVIDIA® BlueField®-3 is a family of advanced IC solutions that integrate a coherent mesh of 64-bit
Armv8.2+ A78 Hercules cores, anNVIDIA® ConnectX®-7network adapter front-end, and a PCI
Express switch into a single chip. The powerful DPU IC architecture includes an Armv multicore
processor array, enabling customers to develop sophisticated applications and highly differentiated
feature sets. Leverages the rich Arm software ecosystem and introduces the ability to offload the
x86 software stack.
At the heart of BlueField-3, the ConnectX-7 network offload controller with RDMA and RDMA over
Converged Ethernet (RoCE) technology delivers cutting-edge performance for networking and
storage applications such as NVMe over Fabrics.Advanced features include an embedded virtual
switch with programmable access lists (ACLs), transport offloads, and stateless encaps/decaps of
NVGRE, VXLAN, and MPLS overlay protocols.
