3.3 Interfaces Detailed Description

3.3.1 DPU System-on-Chip (SoC)

NVIDIA® BlueField®-3
Armv8.2+ A78 Hercules
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,
Converged Ethernet (RoCE) technology delivers cutting-edge performance for networking and
storage applications such as NVMe over
switch with programmable access lists (ACLs), transport offloads, and stateless encaps/decaps of
NVGRE, VXLAN, and MPLS overlay protocols.
is a family of advanced IC solutions that integrate a coherent mesh of 64-bit
cores, an NVIDIA® ConnectX®-7 network adapter front-end, and a PCI
