Product Description
NVIDIA ConnectX-6 Lx MCX623106AN-CDAT 50Gb/s SmartNIC
High-performance 25/50GbE Ethernet SmartNIC designed for modern enterprise and cloud data centers with advanced security and acceleration features.
Product Overview
The NVIDIA ConnectX-6 Lx MCX623106AN-CDAT is a dual-port 25/50GbE Ethernet SmartNIC delivering up to 50 Gb/s total bandwidth with PCIe Gen4 x8 host interface. This OCP 3.0 Small Form Factor adapter provides exceptional performance, advanced security, and accelerated networking at an optimized total cost of ownership.
Featuring Zero-Touch RoCE for simplified RDMA deployments, inline IPsec encryption/decryption acceleration, hardware root-of-trust, and ASAP² SDN offload, this SmartNIC enables secure, high-performance networking for virtualization, NFV, and cloud-native environments.
Key Features
- Up to 50 Gb/s total bandwidth (2x 25GbE or 1x 50GbE)
- Line speed message rate of 75 Mpps
- PCIe Gen 4.0 x8 host interface (backward compatible with Gen3)
- OCP 3.0 Small Form Factor for high-density servers
- Zero-Touch RoCE - no PFC or ECN configuration required
- ASAP² SDN acceleration for overlay networks
- Inline hardware IPsec encryption and decryption
- Hardware root-of-trust with secure boot and secure firmware update
- SR-IOV and VirtIO acceleration for virtualization
- Connection tracking hardware offload
Technology & Architecture
The ConnectX-6 Lx architecture integrates advanced acceleration engines that offload critical networking functions from the host CPU:
ASAP² Acceleration
Offloads the SDN data plane to the SmartNIC, delivering line-rate performance for overlay networks including VXLAN, GENEVE, NVGRE, MPLS, and GTP.
Zero-Touch RoCE
Eliminates the need for Priority Flow Control or Explicit Congestion Notification configuration, enabling simple, resilient RDMA deployments at scale.
Inline IPsec Crypto
Hardware-accelerated encryption and decryption (AES-XTS 256/512-bit) for secure data-in-transit with negligible performance impact.
Hardware Root-of-Trust
Secure boot using RSA cryptography and device-unique key cloning protection ensures firmware authenticity and supply chain security.
Typical Deployments
- Enterprise Data Centers: High-performance 25/50GbE server connectivity
- Cloud and NFV Infrastructure: SDN acceleration for virtualized environments
- AI and Machine Learning Clusters: Low-latency RDMA for distributed workloads
- Security-Sensitive Environments: IPsec encryption with hardware security
- Telecommunications: NFV acceleration with MPLS, GTP, and connection tracking
