Mellanox (NVIDIA) MCX631102AN-ADAT Server Adapter: Bringing 25GbE Intelligent Connectivity to Modern Data Centers

As enterprises accelerate their digital transformation, traffic patterns within data centers are undergoing unprecedented changes. From distributed storage to AI inference, high-frequency trading to virtualized environments, every emerging workload imposes stringent demands on network bandwidth, latency, and CPU utilization. Today, NVIDIA Mellanox officially unveils its latest intelligent server adapter—the Mellanox (NVIDIA) MCX631102AN-ADAT. Built on advanced ConnectX-6 Lx technology, this adapter is designed to deliver a cost-effective 25GbE access layer solution for data centers of all sizes, breaking through the performance bottlenecks of traditional networks.

Traditional 10GbE networks are increasingly struggling to handle the surge in East-West traffic, while a direct leap to 100GbE often involves prohibitive cabling and switch costs. Network engineers and IT managers need to balance performance with total cost of ownership. The Mellanox (NVIDIA) MCX631102AN-ADAT emerges precisely to fill this critical gap. It not only provides 25GbE throughput but, more importantly, leverages hardware offloading to free the CPU from network and storage tasks. This resolves the compute resource contention caused by software switching in virtualized environments, allowing server cores to focus on business-critical applications.

The MCX631102AN-ADAT is far more than a standard Ethernet adapter card. It integrates NVIDIA Mellanox's long-accumulated advanced technologies, offering the following core advantages:

• Leading Ports and Rates: As an MCX631102AN-ADAT ConnectX-6 Lx dual-port 25GbE SFP28 card, it provides two independent 25GbE ports, supporting link aggregation for up to 50Gb/s total bandwidth. It also backward compatible with 10GbE, ensuring a smooth upgrade path for existing network infrastructures.
• Intelligent Offloading and RoCE: Built-in hardware offload engines support overlay network protocols like OVS and VXLAN, significantly reducing virtual switch latency. It also supports RoCE (RDMA over Converged Ethernet), providing a high-performance data path for latency-sensitive storage and AI applications.
• End-to-End Accelerated Security: Support for IPsec and TLS encryption offloading enables data link-layer security without impacting throughput. This is crucial for users in finance, government, and other sectors with stringent data security requirements.

To help architects better assess suitability, we have compiled a core parameter comparison between this card and the previous generation:

Thanks to its excellent compatibility and performance, this MCX631102AN-ADAT Ethernet adapter card solution is versatile enough for a wide range of complex scenarios. Whether deployed as the storage front-end network in a hyper-converged infrastructure or as the communication card for compute nodes in a high-performance computing cluster, it delivers an exceptional experience through low-latency characteristics. For IT managers evaluating new server procurements, the detailed MCX631102AN-ADAT specifications reveal robust virtualization capabilities, fully compatible with VMware, KVM, and major Linux distributions.

The new NVIDIA Mellanox MCX631102AN-ADAT is now in full production and available in both standard full-height and low-profile form factors to meet different server chassis installation requirements.
