The NVIDIA Mellanox MCX631102AN-ADAT is a highly efficient, dual-port 25GbE Ethernet adapter from the high-performance ConnectX-6 Lx series. Designed for modern data centers shifting from 10G to 25GbE infrastructure, this adapter provides the perfect balance between high-speed performance and cost-effectiveness. Utilizing a PCIe 4.0 x8 host interface and Dual-Port SFP28 connectors, it delivers up to 50Gb/s of aggregate bandwidth, ensuring your server infrastructure is ready for the data-intensive demands of virtualization, cloud computing, and big data analytics.
What sets the MCX631102AN-ADAT apart is its advanced "Smart" acceleration engine. It features hardware-based offloads for RDMA over Converged Ethernet (RoCE v2), ASAP² (Accelerated Switch and Packet Processing), and NVMe-over-Fabrics (NVMe-oF). These capabilities directly reclaim valuable CPU cycles, reducing network overhead and significantly lowering the Total Cost of Ownership (TCO). By offloading complex networking tasks to the NIC, your primary compute resources remain dedicated to running critical business applications and AI workloads.
For maximum deployment flexibility, this adapter comes with both Tall and Short (Low-Profile) brackets, ensuring seamless integration into high-density 1U racks, compact enterprise servers, or storage arrays. Whether you are a system integrator or a large-scale data center operator, the MCX631102AN-ADAT offers the reliability and scalability needed to future-proof your network architecture while maximizing the ROI of your current hardware.
Product Description
NVIDIA Mellanox MCX631102AN-ADAT ConnectX®-6 Lx EN Adapter Card, 25GbE Dual-Port SFP28, PCIe4.0 x8, Tall&Short Bracket
ConnectX-6 MCX631102AN-ADAT provides high-performance and flexible solutions with up to two ports of 25GbE connectivity, with a line-speed message rate of 75Mpps when running an open-source Data Path Development Kit (DPDK) PCIe (Gen 4.0). For storage workloads, the 25 Gigabit Ethernet adapter card delivers a range of innovative accelerations, such as Signature Handover (T10-DIF) in hardware, an embedded PCIe Switch, and NVMe over Fabric target offloads to reduce CPU resource consumption and drive extremely high packet rates and throughput. This boosts data center infrastructure efficiency and provides the highest-performance, most flexible solution for Enterprise data centers, Cloud-native, Web 2.0, hyperscale, Telco, and Network Function Virtualization (NFV).
