NVIDIA ConnectX-6 Lx 25/50G Ethernet SmartNIC

1. Product Overview

The NVIDIA ConnectX-6 Lx Ethernet SmartNIC is a high-performance, scalable, and secure network interface card designed for modern enterprise and cloud data centers. Supporting dual-port 25GbE or single-port 50GbE connectivity, this network card delivers advanced networking capabilities with PCIe Gen3 and Gen4 x8 host interfaces. It is engineered to optimize performance, enhance security, and reduce total cost of ownership for demanding data center environments.

2. Key Characteristics

• Line rate message processing up to 75 million packets per second
• Zero-Touch RoCE for seamless RDMA deployment
• ASAP² technology for SDN and VNF acceleration
• Hardware-accelerated IPsec encryption and decryption
• Advanced overlay network support including VXLAN and GENEVE
• Hardware root-of-trust for secure boot and firmware updates

3. Core Technologies

The ConnectX-6 Lx NIC incorporates several cutting-edge technologies:

• RoCE (RDMA over Converged Ethernet) for low-latency networking
• ASAP² (Accelerated Switch and Packet Processing) for offloading virtual switches
• SR-IOV and VirtIO for efficient virtualization
• Inline crypto acceleration for IPsec and AES-XTS
• Programmable parser and connection tracking for stateful firewalling

4. Working Principle

The ConnectX-6 Lx SmartNIC operates by offloading network processing tasks from the host CPU to dedicated hardware. It uses ASAP² to handle software-defined networking (SDN) data planes, RoCE for efficient remote direct memory access, and hardware-accelerated encryption for secure data transmission. The NIC processes packets at line rate, ensuring minimal latency and maximum throughput while reducing CPU overhead.
