Identity & Definition
This enterprise InfiniBand data center switch, the NVIDIA Mellanox MQM9700-NS2F, is a Quantum-2 NDR InfiniBand switch providing 64 NDR ports via 32 OSFP cages at 400Gb/s per port in a 2U managed form factor. The NS2F variant uses P2C (Power-to-Connector) airflow. This is an InfiniBand-only switch — it does not support Ethernet. Condition: NEW.
Engineering Context
The Quantum-2 ASIC delivers 51.2 Tb/s aggregate switching capacity with non-blocking, cut-through forwarding at sub-100ns port-to-port latency. Each of the 32 OSFP cages supports two NDR 400Gb/s lanes, yielding 64 total ports. Adaptive routing, congestion control, and SHARP collective offload are supported natively. The MQM9700 is the spine/core switch for NVIDIA DGX SuperPOD, HGX, and equivalent AI training infrastructure. NVIDIA P/N: 920-9B210-00FN-0M0. P2C airflow directs cooling from the power supply side to the connector/port side.
Deployment & Use Cases
Spine switch in NDR InfiniBand fabrics for AI/ML training clusters (DGX SuperPOD, HGX). Core switch for HPC clusters running MPI, NCCL, or UCX workloads across hundreds or thousands of GPU nodes. High-radix leaf-spine fabric for GPU-to-GPU communication requiring sub-100ns latency. Large-scale scientific computing, molecular dynamics, and weather simulation environments.

Compatibility & Hard Constraints
InfiniBand NDR Only: This is an InfiniBand switch. It does not support Ethernet. For NDR Ethernet, use Spectrum-4 series. OSFP Ports: Requires NDR OSFP transceivers or cables. Not compatible with QSFP-DD, QSFP56, or QSFP28 modules. P2C Airflow: Power-to-Connector cooling direction. Verify this matches your rack airflow configuration. For C2P (Connector-to-Power), use MQM9700-NS2R. NDR Speed Tier: Designed for NDR (400Gb/s). Backward-compatible with HDR (200Gb/s) at reduced speed. Requires ConnectX-7 NDR or later adapters for full NDR operation. Predecessor: Quantum HDR switches (QM8700 series). Successor: Quantum-3 XDR switches (future).
