Mellanox ConnectX-7 Single-Port 200GbE/HDR InfiniBand QSFP112 PCIe 5.0 OCP 3.0 Adapter

The Mellanox ConnectX-7 Single-Port 200GbE/HDR InfiniBand adapter delivers high-performance interconnect in an OCP 3.0 mezzanine form factor, enabling deployment in space-constrained enterprise servers where PCIe slot availability is limited. This adapter supports both 200GbE Ethernet and HDR InfiniBand protocols on a single QSFP112 port, with PCIe 5.0 x16 connectivity for maximum bandwidth utilization in next-generation GPU and compute clusters.

Designed for NVIDIA DGX systems, HPE Cray supercomputers, and other OCP 3.0-compatible platforms, the ConnectX-7 accelerates distributed AI training, large-language model inference, and high-performance computing workloads by reducing inter-node latency and increasing fabric throughput. The OCP 3.0 mezzanine mechanical design eliminates the need for dedicated full-height PCIe slots, preserving motherboard real estate for GPU accelerators and storage controllers.

The adapter incorporates Mellanox's ConnectX-7 silicon with native RDMA over Converged Ethernet (RoCE v2) support, adaptive routing, and congestion control mechanisms. Built-in telemetry and monitoring capabilities enable real-time network health assessment across large-scale clusters.

Ideal for

• Distributed AI model training on GPU clusters requiring sub-microsecond latency inter-node communication
• Large-language model inference farms with high-bandwidth, low-latency requirements between compute nodes
• HPC supercomputing clusters running CFD, molecular dynamics, and scientific simulations
• Data center fabric interconnect for NVLink-based GPU systems with constrained PCIe topologies
• Cloud-native hyperscaler infrastructure requiring 200GbE Ethernet with optional InfiniBand backward compatibility
• Enterprise scale-out analytics platforms leveraging GPU acceleration for real-time data processing
