NVIDIA ConnectX-6 Lx 25/50G Ethernet SmartNIC - MCX631432AN-ADAB
Product Overview
The NVIDIA ConnectX-6 Lx MCX631432AN-ADAB is a high-performance
Ethernet SmartNIC designed for modern enterprise and cloud data
centers. Supporting dual 25GbE or single 50GbE ports, this network
card delivers exceptional throughput, advanced security, and
scalable RoCE capabilities. It is engineered to optimize
virtualized environments, reduce CPU overhead, and provide robust
networking solutions with superior total cost of ownership.
Key Characteristics
- Dual-port 25GbE or single-port 50GbE connectivity
- PCIe Gen4 x8 host interface
- Zero-Touch RoCE for seamless deployment
- ASAP² technology for SDN and VNF acceleration
- Hardware-accelerated IPsec encryption and decryption
- Hardware root-of-trust for secure boot and firmware updates
Core Technologies
The ConnectX-6 Lx NIC leverages several advanced technologies
including RDMA over Converged Ethernet (RoCE), Accelerated Switch
and Packet Processing (ASAP²), and Single Root I/O Virtualization
(SR-IOV). It supports overlay network protocols such as VXLAN,
GENEVE, and NVGRE, and provides hardware offload for IPsec and
connection tracking.
Working Principle
The SmartNIC offloads network processing tasks from the host CPU to
dedicated hardware. Through ASAP², it handles software-defined
networking (SDN) data plane operations, while RoCE enables
high-speed remote direct memory access. Inline crypto acceleration
processes IPsec traffic without burdening the host, ensuring both
performance and security.
Applications
Ideal for cloud data centers, enterprise networks, and
communication service providers (CSPs), this network card is suited
for virtualized servers, NFV infrastructure, high-performance
computing, and storage platforms. It supports both bare-metal and
virtualized deployments with SR-IOV and VirtIO interfaces.
