Product Description
NVIDIA Quantum-2 QM9790-NS2R 400Gb/s InfiniBand Switch
A 1U externally managed NDR InfiniBand switch built on the NVIDIA Quantum-2 switch platform. It delivers 64 ports of 400Gb/s InfiniBand over 32 OSFP connectors, with an aggregated bidirectional throughput of 51.2 Tb/s and C2P (connector-to-power) airflow.
Product Overview
The NVIDIA Quantum-2 based QM9790-NS2R is a 1U fixed-configuration InfiniBand switch designed for extreme-scale HPC and AI systems. It provides 64 ports of NDR 400Gb/s InfiniBand in a standard 1U chassis, using 32 octal small form-factor pluggable (OSFP) connectors. A single switch carries an aggregated bidirectional throughput of 51.2 Tb/s and more than 66.5 billion packets per second (BPPS) capacity.
The QM9790 is the externally managed variant in the Quantum-2 QM9700 series. It is designed to work with the NVIDIA Unified Fabric Manager (UFM) platform, allowing data center operators to provision, monitor, manage, and troubleshoot the modern data center fabric. This model uses connector-to-power (C2P) airflow and is identified by the orderable part number MQM9790-NS2R.

Technology
NVIDIA Quantum-2 Switch Platform
The QM9790-NS2R is built on the NVIDIA Quantum-2 switch platform, the industry-leading switch platform in power and density for NDR 400Gb/s InfiniBand throughput. It is designed for AI developers and scientific researchers working on extreme-scale systems.
NDR 400Gb/s InfiniBand
NDR is an InfiniBand data rate in which each lane of a 4X port runs at 100Gb/s with 64b/66b encoding, resulting in an effective bandwidth of 400Gb/s per port. The QM9790 supports 400Gb/s per port and can use port-split technology to provide 200Gb/s data speeds with double-density radix.
SHARPv3 and In-Network Computing
The QM9700 series extends NVIDIA In-Network Computing technologies and introduces SHARPv3. SHARPv3 creates virtually unlimited scalability for small and large data aggregation through the network, boosting application performance of complex computations while data moves through the data center network.
Externally Managed Architecture
Unlike the internally managed QM9700, the QM9790 is externally managed. It can utilize the advanced NVIDIA Unified Fabric Manager (UFM) feature sets to empower data center operators to efficiently provision, monitor, manage, preventatively troubleshoot, and maintain the modern data center fabric.
Typical Deployments
- Small to medium-sized deployments: Scale with a two-level Fat Tree topology while reducing power, latency, and space requirements
- Top-of-rack (TOR) switching: Up to 128 ports of 200Gb/s using port-split technology, delivering a dense TOR switch option
- HPC and AI clusters: 400Gb/s InfiniBand connectivity for high-resolution simulations, extreme-size datasets, and highly parallelized algorithms
- UFM-managed fabrics: Externally managed architecture for data center operators using NVIDIA UFM
- Multi-topology fabrics: Fat Tree, SlimFly, DragonFly+, multi-dimensional Torus, and more
