NVIDIA Quantum-2 MQM9700-NS2R 400Gb/s InfiniBand Switch – 64-Port NDR, C2P Airflow, On-Board Management

MQM9700-NS2R 400Gb/s InfiniBand Switch - 64-port NDR managed switch with 51.2 Tb/s aggregate throughput, C2P (connector-to-power) airflow, and on-board subnet manager.

The MQM9700-NS2R is a fully managed 400Gb/s InfiniBand fixed-configuration switch from the NVIDIA Quantum-2 series, featuring connector-to-power (C2P) airflow and an on-board subnet manager for simplified deployment. It provides 32 OSFP ports, each capable of 400Gb/s (or 128 ports at 200Gb/s with port-split technology), and offers an aggregate bidirectional throughput of 51.2 Tb/s. With built-in management, SHARPv3 in-network computing, and advanced congestion control, the MQM9700-NS2R is ideal for medium to large-scale HPC, AI, and enterprise clusters where self-contained management and C2P airflow are required.

The Quantum-2 platform integrates the third-generation SHARP technology (SHARPv3), enabling in-network data aggregation that reduces data movement and accelerates AI training and HPC simulations. Combined with Remote Direct Memory Access (RDMA) and NVIDIA's Scalable Hierarchical Aggregation and Reduction Protocol, the MQM9700-NS2R dramatically improves application performance while data traverses the fabric. The on-board subnet manager provides full chassis management through CLI, WebUI, SNMP, or JSON interfaces, simplifying deployment and operations.

The MQM9700-NS2R is recommended for deployments that require a self-contained management solution with on-board subnet manager, up to 2,000 nodes, and connector-to-power airflow. For larger fabrics or advanced UFM features, consider the externally managed QM9790 series.

MQM9700 includes an on-board subnet manager and is fully managed out-of-the-box for up to 2,000 nodes. MQM9790 is externally managed and leverages NVIDIA UFM for advanced fabric management, ideal for larger, more dynamic environments.

C2P (connector-to-power) airflow means air enters from the connector side and exits through the power supply side. This is the reverse of P2C (front-to-rear) and is used in data centers with specific hot-aisle/cold-aisle configurations.

Yes, the switch is backward compatible with HDR, EDR, and FDR speeds, allowing incremental upgrades.

OSFP connectors support passive/active copper and active fiber cables. Both optical modules and direct-attach cables can be used.

Yes, using NVIDIA port-split technology, the MQM9700-NS2R can provide up to 128 ports at 200Gb/s.
