NVIDIA ConnectX-6 Lx 25/50G Ethernet SmartNIC Model: MCX631102AN-ADAT | Dual-port 25G / Single-port 50G | PCIe
4.0 x8 | Crypto + RoT Accelerate modern data center workloads with the NVIDIA®
ConnectX®-6 Lx Ethernet smart network interface card. The
MCX631102AN-ADAT delivers up to 50Gb/s throughput, advanced RoCE
with Zero-Touch deployment, SDN data plane offload via ASAP², and
inline IPsec encryption. Built with hardware root-of-trust for
secure boot and firmware update, this OCP 3.0 SmartNIC brings
carrier-grade reliability to enterprise and cloud infrastructure. Product Overview The NVIDIA ConnectX-6 Lx series -- model MCX631102AN-ADAT -- is
purpose-built for 25GbE and 50GbE connectivity in enterprise data
centers, telco NFV, and AI storage fabrics. Featuring PCI Express
Gen 4.0 x8 host interface, the adapter supports two ports of
10/25GbE or a single port of 50GbE. Advanced offloads include ASAP²
for SDN (VXLAN, GENEVE, NVGRE, MPLS, GTP), stateful connection
tracking (L4 firewall), and VirtIO acceleration for containerized
environments. The hardware-accelerated security engine provides
inline IPsec encryption/decryption and secure chain-of-trust,
reducing CPU load while fortifying east-west traffic. Key Features
Advanced Technology & Acceleration NVIDIA ASAP² (Accelerated Switch and Packet Processing) Offloads the entire SDN data plane to the SmartNIC, dramatically
reducing hypervisor CPU utilization while delivering wire-speed
encapsulation/decapsulation for VXLAN, GENEVE, NVGRE, MPLS, and
GTP. Ideal for NFV transitions and cloud-native infrastructure. Industry-leading RoCE with Zero-Touch (ZTR) ConnectX-6 Lx enables seamless RDMA over Converged Ethernet on
existing Layer 2/3 networks. Zero-Touch RoCE eliminates the need
for Priority Flow Control (PFC) or Explicit Congestion Notification
(ECN) configuration, making RoCE deployment as simple as standard
Ethernet while maintaining lossless efficiency and resiliency. Inline Security & Platform Integrity The on-chip IPsec engine performs encryption/decryption at line
rate, freeing host CPU cores. Hardware root-of-trust (RoT) verifies
firmware signature during boot and updates, ensuring protection
from cloning and supply chain attacks -- essential for finance,
government, and edge infrastructure. Typical Deployments & Use Cases
Platform & Software Compatibility MCX631102AN-ADAT is validated with major server platforms, Linux
distributions, Windows Server, and leading virtualization stacks.
Full management support includes NC-SI, MCTP, and PLDM for
monitoring/firmware update.

Why Choose ConnectX-6 Lx MCX631102AN-ADAT
Frequently Asked Questions Q1: Is MCX631102AN-ADAT backward compatible with PCIe Gen3 servers? A: Yes, the card supports PCIe Gen3 x8 electrical and mechanical,
bandwidth limited to Gen3 speeds. Q2: What is the difference between MCX631102AN-ADAT and
MCX623106AN-CDAT? A: Both are ConnectX-6 Lx OCP 3.0 SmartNICs with crypto & RoT.
The MCX631102AN-ADAT is often factory-configured for specific 25GbE
deployments; please check regional ordering codes. Starsurge can
confirm exact feature parity on request. Q3: Does this card support dual-port 25G and single-port 50G
concurrently? A: The adapter can operate in either dual-port 25GbE or single-port
50GbE mode (depending on cabling/optics). Q4: Can I use Zero-Touch RoCE in a mixed-vendor network? A: Yes, ZTR enables RoCE on standard Ethernet switches without
PFC/ECN, but best performance is achieved with recommended
configuration; consult Starsurge. Q5: How do I request a quote or check stock? A: Contact Starsurge sales via website RFQ form or email. We
provide real-time pricing, lead times, and volume discounts. Precautions & Ordering Notes
