Overview

Product overview

NVIDIA ConnectX-6 Lx Ethernet SmartNICs bring breakthrough efficiency to 25GbE deployments. The model MCX631432AN-ADAB is a PCIe low-profile form factor adapter equipped with advanced ASAP2 acceleration, hardware root-of-trust, and full support for RoCE (RDMA over Converged Ethernet). Whether you are virtualizing network functions, securing east-west traffic, or building a high-frequency trading environment, this SmartNIC offloads the data plane and ensures line-rate performance at up to 75 million packets per second (Mpps). Ideal for enterprises, telecom CSPs, and cloud providers looking to optimize server utilization without compromising security or scalability.

Key features

  • High Throughput and Connectivity: Dual-port 10/25GbE or single-port 50GbE; total bandwidth up to 50Gb/s.
  • PCIe Gen4 and Gen3 x8: Host interface compatible with PCIe 4.0 (8 lanes) and backward compatible to Gen3.
  • ASAP2 SDN Acceleration: Offloads overlay encapsulations (VXLAN, GENEVE, NVGRE) and stateful connection tracking (L4 firewall).
  • Zero-Touch RoCE (ZTR): Seamless RDMA deployment without PFC or ECN configuration; resilient and scalable.
  • Inline IPsec Crypto Acceleration: AES-XTS 256/512-bit hardware encryption and decryption, supports IPsec over RoCE.
  • Hardware Root of Trust: Secure boot, RSA-authenticated firmware updates, device-unique key for clone protection.
  • Programmable Flexible Parser and Flow Steering: Header rewrite, flow mirroring, sampling, hierarchical QoS.
  • Virtualization Ready: SR-IOV, VirtIO acceleration, overlay offloads for containerized and virtualized environments.

Typical applications

  • Cloud and Enterprise Data Centers: Accelerate Open vSwitch (OVS) and SDN controllers; offload connection tracking for stateful firewalls.
  • NFV and Telecom Infrastructures: Deploy virtualized packet gateways, GTP encapsulation and decapsulation, and MPLS acceleration.
  • High-Performance Storage and HPC: RoCE-based NVMe over Fabrics, distributed storage (Ceph, Lustre) with low latency.
  • Edge and AI Inference Servers: 50GbE single-port density for edge nodes requiring inline security and small form factor (OCP 3.0 options available).
  • Financial Services: Hardware offload for market data feeds, low-latency trading with flow mirroring and packet sampling.
