3.2 Interfaces Detailed Description
3.2.1 System-on-Chip (SoC)
NVIDIA BlueField-3 DPU Controller is a family of advanced DPU Controller 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 Controller 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.
3.2.1.1 Encryption
DPU Controller addresses the concerns of modern data centers by combining hardware encryption
accelerators with embedded software and fully integrated advanced network capabilities, making it
an ideal platform for developing proprietary security applications. It enables a distributed security
architecture by isolating and protecting each workload and providing flexible control and visibility
at the server and workload level; controlling risk at the server access layer builds security into the
DNA of the data center and enables prevention, detection, and response to potential threats in real-
time. DPU Controller can deliver powerful functionality, including encryption of data-in-motion,
bare-metal provisioning, stateful L4 firewall, and more.
