Product Description
NVIDIA ConnectX-6 Lx 25/50G Ethernet SmartNIC
Flagship SmartNIC with advanced networking, security, and acceleration capabilities for modern data centers.
Product Overview
Engineered for modern cloud and enterprise data centers, the NVIDIA ConnectX-6 Lx SmartNIC delivers line-rate 25/50GbE performance with advanced RoCE, hardware root-of-trust security, and full SDN acceleration. The MCX623436AN-CDAB variant supports crypto capabilities, SFP28/QSFP28 options, and OCP 3.0 small form factor.
Built on NVIDIA's proven ConnectX architecture, this adapter supports up to two ports of 10/25GbE or a single 50GbE port with total bandwidth up to 50Gb/s. With PCIe Gen3/Gen4 x8 host interface, it offloads CPU-intensive tasks including overlay tunneling, stateful connection tracking, and SDN data plane processing.
Key Features
- Line-rate 75Mpps message rate at full wire speed
- Advanced RoCE with Zero-Touch RoCE for resilient and scalable deployment
- ASAP2 SDN Acceleration for VXLAN, GENEVE, NVGRE, MPLS, and GTP offload
- Inline IPsec Crypto with AES-XTS 256/512-bit encryption
- Hardware Root-of-Trust with secure boot and cloned protection
- SR-IOV & VirtIO offload for maximum VM/container density
Technology Highlights
Smart Acceleration Inside
ASAP2 (Accelerated Switch and Packet Processing) offloads the entire SDN data pipeline to the SmartNIC, accelerating vSwitch performance while freeing host CPU cores for application logic.
RoCE with Zero-Touch eliminates traditional RDMA configuration barriers, running seamlessly on existing Ethernet networks without PFC/ECN tuning.
Platform security includes immutable hardware root-of-trust, secure firmware update mechanism, and per-device unique keys to prevent counterfeiting.

Buyer Checklist
- Confirm server interface: OCP 3.0 slot (SFF) or PCIe low-profile required
- Validate power budget and cooling capacity inside chassis
- Determine need for crypto (IPsec): MCX623436AN-CDAB includes inline engine
- Review transceiver compatibility: use validated SFP28 modules for 25G links
Frequently Asked Questions
