NVIDIA Mellanox MCX653105A-HDAT 200G QSFP56 VPI Adapter

Accelerate 200G fabrics with ConnectX-6 VPI performance

NVIDIA ConnectX-6 VPI MCX653105A-HDAT delivers high-throughput networking over a single QSFP56 port with dual-protocol flexibility for Ethernet and InfiniBand. It supports Ethernet up to 200 Gb/s and InfiniBand up to HDR/HDR100, enabling fast, low-latency links for modern clusters and storage fabrics. With PCI Express Gen3/4 x16, it integrates cleanly into performance-critical servers.

Key Benefits & Features

• 200G dual-protocol: Operate as 200GbE or HDR/HDR100 InfiniBand on one QSFP56 port for maximum deployment flexibility.
• Broad speed negotiation: Auto-negotiates IB SDR/DDR/QDR/FDR/FDR10/EDR/HDR100/HDR and Ethernet 1/10/25/40/50/100/200G for backward compatibility.
• PCIe Gen4 x16 bandwidth: SERDES at 8.0/16 GT/s ensures headroom for high-throughput, latency-sensitive workloads.
• Thermal-ready design: Defined airflow options (heatsink-to-port or port-to-heatsink) with LFM and temperature guidance for reliable operation.
• Data center compliance: RoHS compliant with global safety and EMC certifications for smooth qualification.

Ideal Use Cases

• High-performance computing clusters requiring HDR InfiniBand or 200GbE
• AI and machine learning training or inference nodes
• RDMA-enabled storage and NVMe-based fabric backbones
• Hybrid IB/Ethernet data centers consolidating on QSFP56
• 100/200G aggregation and server access upgrades
