Product Model: MCX631102AS-ADAT | Form Factor: OCP 3.0 Small Form Factor (SFF) | Data Rate: Dual-Port 25GbE | Host Interface: PCIe 4.0 x8
Transform Your Server's Network Efficiency
The MCX631102AS-ADAT is not just a network card; it's a data center accelerator in a compact OCP 3.0 form factor. Designed for modern hyperscale and cloud-optimized servers, it delivers full line-rate 25GbE performance while offloading critical networking, storage, and security workloads from the host CPU. This results in higher server utilization, reduced latency, and a significantly lower total cost of ownership for high-density deployments, perfectly aligning with infrastructure built on platforms like the mq9700 series.
1. Product Overview
The NVIDIA ConnectX-6 Lx MCX631102AS-ADAT represents the evolution of the data center NIC card, purpose-built for open compute platform (OCP) architectures. This SmartNIC combines dual 25GbE SFP28 interfaces with a suite of hardware accelerators to tackle the performance bottlenecks of virtualized and software-defined infrastructure. By handling complex packet processing, RDMA operations, and encryption directly on the adapter, it liberates valuable server CPU cores for revenue-generating applications. This model is integral for operators seeking to maximize the efficiency and agility of their cloud, telco, or enterprise data centers.
2. Key Characteristics
High-Speed Ports: 2 x SFP28 supporting 10GbE/25GbE.
OCP 3.0 SFF: Standardized form factor for modern rack servers.
ASAP2 Acceleration: Full offload of VXLAN, GENEVE, and NVGRE tunneling.
Zero-Touch RoCE: Enables low-latency RDMA on standard networks.
Inline IPsec: Hardware encryption/decryption at line rate.
3. Core Technology & Standards
This SmartNIC is engineered with several groundbreaking technologies that define next-generation data center networking:
ASAP² (Accelerated Switch and Packet Processing): This technology transforms the network card into a programmable switch data plane, offloading entire virtual switch functionalities and improving VM-to-VM communication performance by up to 10x.
Zero-Touch RoCE (ZTR): An intelligent RoCE implementation that dynamically adapts to network conditions, delivering the benefits of RDMA without the operational complexity of configuring lossless Ethernet domains.
Hardware Root of Trust (RoT): Embedded security using unique device keys and RSA cryptography to ensure firmware authenticity and prevent unauthorized cloning, a critical feature for secure supply chains.
OCP 3.0 Compliance: Adheres to the Open Compute Project's specification for network adapters, ensuring mechanical, thermal, and management interoperability in compliant server designs.
4. How It Works: The Smart Processing Pipeline
The MCX631102AS-ADAT operates on a principle of intelligent offload. When network packets arrive, they are processed through a multi-stage pipeline on the SmartNIC itself. The programmable parser classifies traffic. Overlay-encapsulated packets are stripped of their tunnels by the ASAP2 engine. RDMA (RoCE) traffic is placed directly into application memory, bypassing the CPU. IPsec packets are decrypted inline. All these operations occur at wire speed, with results passed efficiently to the host or back onto the network. This approach turns a passive NIC card into an active processing node, drastically reducing the load on the server's main processors—a concept synergistic with the efficiency goals of the mq9700 switch series.
5. Target Applications & Deployments
Hyperscale Public Clouds: Provides secure, multi-tenant network isolation and acceleration for virtual machines and containers.
Telecom & NFV Infrastructure: Offloads virtual network functions (VNFs) like vRouter, vFirewall, and 5G UPF, enabling higher throughput and lower latency.
High-Performance Storage: Accelerates NVMe-over-Fabrics (NVMe-oF) and software-defined storage platforms using low-latency RoCE.
AI/ML Training Clusters: Delivers high-bandwidth, CPU-efficient interconnects for distributed training workloads across server nodes.
Secure Edge Gateways: Establishes high-performance, encrypted WAN links for distributed enterprise or telco edge sites.

9. Frequently Asked Questions
Q: Is this OCP NIC compatible with my standard PCIe server?
A: No. The MCX631102AS-ADAT uses the OCP 3.0 SFF connector (a pin-based edge connector) and is designed specifically for server motherboards that include an OCP NIC 3.0 slot. It is not mechanically compatible with a standard PCIe slot. For PCIe-based servers, please inquire about models like the MCX623106AN-CDAT.
Q: What software or orchestrator support does it have?
A: It is fully supported by major operating systems (Linux, Windows), hypervisors (ESXi, Hyper-V, KVM), and cloud orchestration platforms (OpenStack, Kubernetes via Multus CNI). The NVIDIA MLNX_EN OFED drivers and SDK provide advanced programmability and management capabilities, making this NIC card a versatile choice for automated environments.
10. Installation & Operational Notes
Mechanical Compatibility: Confirm your server chassis and motherboard support the OCP 3.0 SFF form factor before purchase.
Thermal Management: Ensure the server's cooling design provides adequate airflow over the OCP mezzanine area as per OCP thermal guidelines.
Firmware and Drivers: Always use the recommended pair of firmware and driver versions from the NVIDIA support portal for optimal stability and feature support.
BMC Configuration: For out-of-band management via NC-SI, ensure the baseboard management controller (BMC) is correctly configured.
