Product Description
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 significantly lower total cost of ownership for high-density deployments.
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 performance bottlenecks of virtualized and software-defined infrastructure.
- High-Speed Ports: 2 x SFP28 supporting 10GbE/25GbE
- OCP 3.0 SFF: Standardized form factor for modern rack servers
- PCIe 4.0 x8: High-bandwidth host interface, Gen3 compatible
- 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
- ASAP² (Accelerated Switch and Packet Processing): Transforms the network card into a programmable switch data plane, offloading virtual switch functionalities
- Zero-Touch RoCE (ZTR): Intelligent RoCE implementation that dynamically adapts to network conditions
- Hardware Root of Trust (RoT): Embedded security using unique device keys and RSA cryptography
- OCP 3.0 Compliance: Adheres to Open Compute Project specifications for mechanical, thermal, and management interoperability
- Hyperscale Public Clouds: Secure, multi-tenant network isolation and acceleration
- Telecom & NFV Infrastructure: Offloads virtual network functions (VNFs)
- High-Performance Storage: Accelerates NVMe-over-Fabrics (NVMe-oF)
- AI/ML Training Clusters: High-bandwidth, CPU-efficient interconnects
- Secure Edge Gateways: High-performance, encrypted WAN links

- Optimized for Modern Server Designs: OCP 3.0 SFF form factor tailored for high-density, thermally efficient rack servers
- Uncompromising Performance per Watt: Dramatically reduces server power consumption associated with networking
- Simplified Operations at Scale: Zero-Touch RoCE and standardized OCP management interfaces reduce configuration burden
- Robust Security Foundation: Integrates security from the silicon up, protecting device integrity and data flow
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.
A: It is fully supported by major operating systems (Linux, Windows), hypervisors (ESXi, Hyper-V, KVM), and cloud orchestration platforms (OpenStack, Kubernetes). The NVIDIA MLNX_EN OFED drivers and SDK provide advanced programmability and management capabilities.
- Mechanical Compatibility: Confirm server chassis and motherboard support OCP 3.0 SFF form factor
- Thermal Management: Ensure adequate airflow over the OCP mezzanine area per OCP thermal guidelines
- Firmware and Drivers: Use recommended firmware and driver versions from NVIDIA support portal
- BMC Configuration: Ensure baseboard management controller is correctly configured for out-of-band management
