Descrizione di prodotto
NVIDIA ConnectX-6 Lx SmartNIC
MCX631102AS-ADAT | OCP 3.0 25/50GbE Ethernet Adapter with Crypto and SDN Acceleration
Deliver scalable, secure, and high-performance networking for modern cloud and enterprise data centers. The ConnectX-6 Lx MCX631102AS-ADAT features OCP 3.0 small form factor, dual-port 10/25GbE or single-port 50GbE connectivity, PCIe Gen4 x8 host interface, inline IPsec encryption, and Zero-Touch RoCE — designed to reduce CPU overhead and accelerate SDN and NFV workloads in dense server deployments.
Product Overview
NVIDIA ConnectX-6 Lx Ethernet SmartNICs bring breakthrough efficiency to 25GbE deployments. The model MCX631102AS-ADAT is an OCP 3.0 small form factor (SFF) adapter equipped with advanced ASAP2 acceleration, hardware root-of-trust, and full support for RoCE (RDMA over Converged Ethernet). The OCP 3.0 form factor enables hot-pluggable, tool-less installation in OCP-compliant servers, making it ideal for hyperscale data centers and cloud builders. 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).
Key Features
- High Throughput and Connectivity: Dual-port 10/25GbE or single-port 50GbE; total bandwidth up to 50Gb/s
- OCP 3.0 Small Form Factor: Hot-pluggable, tool-less installation, compliant with Open Compute Project specifications
- 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
- Virtualization Ready: SR-IOV, VirtIO acceleration, overlay offloads for containerized and virtualized environments
Technology Deep Dive
The ConnectX-6 Lx integrates NVIDIA ASAP2 (Accelerated Switch and Packet Processing) technology, enabling full SDN data plane offload to the SmartNIC. This dramatically reduces CPU burden in software-defined data centers while supporting both cloud (VXLAN, GENEVE) and telecom (MPLS, GTP) encapsulations. Meanwhile, Zero-Touch RoCE eliminates legacy RDMA configuration pains, allowing RoCE traffic to run on standard Ethernet fabrics without priority flow control or explicit congestion notification. Combined with inline IPsec cryptography, the adapter secures data in transit at line rate, preserving performance for encrypted east-west communications. Hardware root-of-trust further protects the supply chain, ensuring that only authenticated firmware executes during boot.
Typical Deployments
- Hyperscale Cloud Data Centers: OCP 3.0 compatibility enables standardized, high-density server deployments
- 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 OCP compatibility
Compatibility and Ecosystem

- Linux: RHEL, Ubuntu, Debian, CentOS, Rocky Linux, SUSE
- Windows Server 2019 and 2022
- VMware ESXi (with SR-IOV and VirtIO offload)
- Container runtimes: Docker, containerd with CNI plugins

Frequently Asked Questions
Q1: What is the difference between MCX631102AS-ADAT and MCX631102AN-ADAB?
A: Both include IPsec crypto acceleration. The ADAT uses OCP 3.0 small form factor (hot-pluggable, tool-less), while the ADAB uses PCIe low-profile form factor for standard server slots. The "AS" designation indicates OCP 3.0 form factor.
Q2: Does this card support 50GbE on a single port?
A: Yes, the dual-port adapter can be configured as one 50GbE port (using breakout cables) or two independent 25GbE or 10GbE ports.
Q3: What is OCP 3.0 and why is it important?
A: OCP 3.0 is an open hardware standard for network adapters, enabling hot-swappable, tool-less installation and improved serviceability in hyperscale data centers.
Q4: Is Zero-Touch RoCE compatible with my existing switches?
A: ZTR works on standard lossy Ethernet networks without requiring PFC or ECN, making it far easier to deploy compared to traditional RoCE.
Q5: What is the typical lead time for MCX631102AS-ADAT?
A: Standard lead time is 2 to 4 weeks depending on quantity. Contact Starsurge for current stock availability.

- Determine crypto requirement: ADAT includes IPsec, non-crypto variants available
- Ensure OS and driver compatibility with ConnectX-6 Lx series
- Contact Starsurge for volume pricing and lead time
Precautions and Ordering Notes: Ensure your server chassis has an OCP 3.0 compliant mezzanine slot. Use certified SFP28 optical or DAC cables for 25/50GbE operation. For crypto functionality, appropriate software configuration may be required; refer to NVIDIA DOCA framework. Parameters not explicitly listed (e.g., exact power consumption) should be confirmed before volume orders.
