Productomschrijving
NVIDIA Quantum-2 MQM9790-NS2R 400Gb/s InfiniBand Switch
64-port 400Gb/s NDR unmanaged switch with C2P airflow, designed for hyperscale AI and HPC clusters requiring external fabric management via NVIDIA UFM.
Product Overview
The NVIDIA Quantum-2 MQM9790-NS2R is a fixed-configuration 1U InfiniBand switch from the QM9700 series, offering 64 non-blocking ports at 400Gb/s (NDR). With an aggregate bidirectional throughput of 51.2 terabits per second and over 66.5 billion packets per second, it is built for extreme-scale workloads.
The NS2R variant features connector-to-power (C2P) reverse airflow, ideal for data center rows where cold air is drawn from the opposite side. As an unmanaged model, it relies on external controllers such as NVIDIA Unified Fabric Manager (UFM) for advanced orchestration, monitoring, and proactive troubleshooting.
Key Features
- 64 ports of 400Gb/s NDR - Full wire-speed non-blocking switching in 1U
- 51.2 Tb/s aggregate throughput + 66.5 BPPS capacity
- NVIDIA SHARPv3 in-network computing acceleration
- C2P reverse airflow (NS2R) - Connector-side intake, power-side exhaust
- Unmanaged + UFM ready for centralized provisioning and telemetry
- 1+1 redundant hot-swappable PSU - 80 PLUS Gold+ certified
- RDMA, adaptive routing, and congestion control
- Backward compatible with HDR 200G, EDR 100G, and FDR
Technology - SHARPv3 & In-Network Computing
The MQM9790-NS2R integrates the third generation of NVIDIA Scalable Hierarchical Aggregation and Reduction Protocol (SHARPv3). By performing data reduction operations inside the switch fabric, it drastically reduces the volume of data that must traverse the network between endpoints, directly accelerating AI frameworks and scientific simulations.
Typical Deployments
- Large-Scale AI Clusters - GPU-accelerated data centers requiring centralized fabric management
- Hyperscale HPC Environments - SlimFly, DragonFly+, and Fat Tree topologies
- Multi-Tenant Cloud Data Centers - Unmanaged switches controlled via UFM for multi-cluster automation
- Research & National Labs - Advanced telemetry and predictive maintenance requirements

Frequently Asked Questions
Q: What is the main difference between MQM9790-NS2R and MQM9700-NS2R?
A: MQM9790-NS2R is unmanaged and does not include an on-board subnet manager; it is designed to be managed by external controllers like NVIDIA UFM. MQM9700-NS2R includes an internal subnet manager for standalone operation up to 2000 nodes.
Q: Can I use the C2P (NS2R) model in a standard front-to-rear cooling data center?
A: C2P airflow draws air from the connector side (rear) to the power side (front). It is intended for specific reverse-cooling architectures. Please verify your rack cooling direction before ordering.
