NVIDIA ConnectX-6 Lx 25/50GbE SmartNIC - MCX623436AN-CDAB

1. Product Overview

The NVIDIA ConnectX-6 Lx SmartNIC (Model: MCX623436AN-CDAB) is an intelligent network interface card designed for modern enterprise data centers requiring high-performance, secure networking. This advanced NIC card delivers up to 50GbE connectivity with hardware-accelerated security, SDN offload capabilities, and industry-leading RoCE performance. Ideal for cloud, enterprise, and communications service providers, this network card represents the next evolution in data center networking technology.

2. Key Characteristics

• Dual-port 25GbE or single-port 50GbE Ethernet connectivity
• Hardware-accelerated IPsec encryption and decryption
• Zero-Touch RoCE for simplified high-performance networking
• ASAP² technology for SDN and NFV acceleration
• Hardware root-of-trust for enhanced security

3. Core Technologies

The ConnectX-6 Lx SmartNIC incorporates several advanced technologies:

• RDMA over Converged Ethernet (RoCE) v2
• Accelerated Switch and Packet Processing (ASAP²)
• Single Root I/O Virtualization (SR-IOV)
• VirtIO hardware acceleration
• Overlay network protocols: VXLAN, GENEVE, NVGRE

4. Working Principle

This SmartNIC offloads networking, security, and virtualization functions from the host CPU to dedicated hardware processors. The ASAP² engine processes software-defined networking data paths directly on the NIC, while the crypto engine performs inline IPsec encryption/decryption at line rate. RoCE capabilities enable direct memory access between servers with minimal CPU involvement, significantly reducing latency and improving throughput for data-intensive applications.

5. Applications

• Enterprise data center networking and storage
• Cloud infrastructure and virtualization platforms
• Network Function Virtualization (NFV) deployments
• High-performance computing clusters
• Security-sensitive environments requiring encrypted communications

6. Specifications

7. Advantages
