NVIDIA ConnectX-6 Dx/Lx 200G/50G Ethernet SmartNIC Adapter Cards - PCIe Gen4 Dual-Port

NVIDIA ConnectX-6 Dx and ConnectX-6 Lx SmartNICs are high-performance, secure, and feature-rich network adapters tailored for next-gen cloud, AI, storage, and enterprise environments. With support for advanced offloads, crypto acceleration, RoCE v2, and open-source integration, these NICs deliver unmatched throughput, scalability, and efficiency across all workloads.

ConnectX-6 Dx supports single- or dual-port 25/50/100/200GbE and offers hardware-accelerated TLS/IPsec encryption, making it ideal for zero-trust data centres and secure high-performance computing. Meanwhile, ConnectX-6 Lx provides an economical yet powerful solution with single- or dual-port 25/50GbE, perfect for cloud-scale deployments.

KEY FEATURES:

ConnectX-6 Dx

• Single/Dual-port 100/200GbE (PCIe Gen4 x16)
• RoCE v2 with congestion control
• Hardware offload for TLS, IPsec, MACsec
• GPUDirect, NVMe-oF, SR-IOV, and OVS offloads
• Precision time protocol (PTP) and telemetry
• PCIe Gen 4.0 and NVMe acceleration support

ConnectX-6 Lx

• Single/Dual-port 25/50GbE (PCIe Gen4 x8)

ConnectX SmartNICs are purpose-built for software-defined infrastructure. Their ability to offload virtual switch and storage functions frees up host CPU resources and significantly improves application performance. Combined with NVIDIA DOCA, users can accelerate security, telemetry, and orchestration in both bare-metal and virtualised environments. These capabilities make ConnectX-6 Dx and Lx a core component in next-gen data centre and cloud-native architectures.

SECURITY AND TELEMETRY:

• IPsec, TLS, and MACsec hardware offloads (ConnectX-6 Dx)
• Secure boot and firmware attestation
• Support for Arm TrustZone and NVIDIA BlueField DPU compatibility
• Programmable telemetry, flow counters, packet tracing
