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

• Superior performance with 75 million packets per second throughput
• Reduced CPU overhead through hardware offloads
• Enhanced security with inline encryption and secure boot
• Simplified RoCE deployment with Zero-Touch technology
• Comprehensive virtualization support with SR-IOV and VirtIO

8. Service & Support

We provide comprehensive support including a 3-year warranty, global shipping, and 24/7 technical consultation. Our experienced team offers integration assistance and custom configuration services. Bulk pricing and OEM options available for large deployments.

9. FAQ

Q: Is this NIC card compatible with existing 10GbE infrastructure?
A: Yes, the ConnectX-6 Lx supports backward compatibility with 10GbE networks.

Q: Does this network card support both Ethernet and InfiniBand?
A: This model supports Ethernet only. For InfiniBand connectivity, consider other ConnectX-6 variants.

Q: What operating systems are supported?
A: The card supports various Linux distributions, VMware ESXi, Windows Server, and other enterprise OS platforms.

10. Precautions

• Ensure proper cooling as the card may generate significant heat under full load
• Verify PCIe slot compatibility (requires x8 mechanical slot)
• Use qualified optical transceivers and cables for optimal performance
• Update to latest firmware for security patches and feature enhancements
