Mellanox ConnectX-6 Single-Port 200GbE HDR100 QSFP56 PCIe 4.0 x16 Adapter

The Mellanox ConnectX-6 Single-Port 200GbE HDR100 adapter delivers ultra-high-bandwidth connectivity for next-generation data center infrastructure. Built on PCIe 4.0 x16 architecture, this QSFP56-based network interface card provides 200 Gbps single-port performance optimized for low-latency, high-throughput applications requiring sustained data movement at scale.

Engineered for HPC and AI training environments, the ConnectX-6 HDR100 adapter integrates advanced offload engines including RDMA over Converged Ethernet (RoCE v2), GPUDirect RDMA, and hardware-accelerated packet processing. These capabilities reduce CPU overhead while enabling direct GPU-to-GPU communication patterns critical for distributed machine learning and scientific computing workloads.

The adapter supports InfiniBand HDR100 and Ethernet HDR100 modes, providing flexible deployment across homogeneous and hybrid cluster architectures. Native support for adaptive routing, congestion control, and quality-of-service mechanisms ensures deterministic performance in multi-tenant enterprise environments.

Ideal for

• Large-scale distributed AI model training with GPU clusters requiring sub-microsecond inter-node latency
• High-performance computing simulations and molecular dynamics requiring sustained 200 Gbps bandwidth between compute nodes
• Real-time financial risk modeling and algorithmic trading infrastructure with strict latency requirements
• Data warehouse acceleration and ETL pipeline orchestration in analytics platforms
• Kubernetes and container orchestration in hyperscale environments with intensive north-south traffic patterns
• Scientific research computing including climate modeling, genomics analysis, and quantum simulations
