Frequently Asked Questions

What is NDR InfiniBand?

NDR (Next Data Rate) is the 400Gb/s generation of InfiniBand — delivering 400Gb/s per port with sub-microsecond latency. It doubles the bandwidth of HDR (200Gb/s) and is the current leading-edge InfiniBand standard for AI/ML and HPC deployments.

What does the -NS2R suffix indicate?

In the MQM9700-NS2R part number, N indicates front-to-back airflow, S indicates standard power supply, 2 indicates the power supply count, and R indicates rear exhaust. This is the front-to-back airflow variant — select -HS2R for rear-to-front airflow.

The NVIDIA Mellanox MQM9700-NS2R QM9700 delivers 32-port 400Gb/s NDR InfiniBand switching with front-to-back airflow, SHARP in-network computing, and sub-microsecond latency — the next-generation InfiniBand fabric switch for AI/ML training clusters, HPC supercomputers, and high-performance storage networking.
