Product Description
64 non-blocking ports of 400Gb/s NDR in a 1U chassis. Delivers 51.2Tb/s aggregate throughput with SHARPv3 in-network computing, ultra-low latency, and redundant power - purpose-built for extreme-scale HPC and AI data centers.
Part Number: MQM9790-NS2F Airflow: P2C (Front-to-Rear) Management: Externally Managed Form Factor: 1U Rackmount
The NVIDIA MQM9790-NS2F is a fixed-configuration Quantum-2 InfiniBand switch based on the industry-leading NDR 400Gb/s architecture. Designed for extreme-scale HPC and AI workloads, this externally managed variant provides 64 non-blocking ports (via 32 OSFP connectors) in a compact 1U form factor, delivering an astonishing 51.2Tb/s of bidirectional throughput and over 66.5 billion packets per second.
The MQM9790-NS2F is optimized for environments where a centralized Subnet Manager (such as NVIDIA UFM) orchestrates fabric control. It includes SHARPv3 in-network computing, adaptive routing, RDMA, and advanced congestion control - enabling researchers and AI developers to tackle the most demanding data-intensive challenges with unprecedented performance and scalability.
- 64 ports of 400Gb/s NDR (32 OSFP connectors)
- 51.2Tb/s non-blocking aggregate throughput
- >66.5 billion packets per second (BPPS)
- SHARPv3 in-network computing (32x AI acceleration)
- 1+1 redundant hot-swappable AC power
- Hot-swappable fan units, 80 PLUS Gold+ certified
- Port-split technology: up to 128 ports at 200Gb/s
- Adaptive routing, RDMA, and congestion control
- Backward compatible with HDR and EDR
- RoHS-6 compliant, CE / FCC / VCCI certified
The NVIDIA Quantum-2 platform introduces the third generation of SHARP technology (SHARPv3), delivering up to 32X higher AI acceleration than the previous generation. By offloading collective operations from the CPU to the switch network, SHARPv3 dramatically reduces MPI operation time and data traversal across the fabric.
Quantum-2 ASIC integrates advanced features: port-split for double-density 200Gb/s, adaptive routing, enhanced VL mapping, and self-healing network capabilities. The onboard x86 Coffee Lake i3 CPU runs MLNX-OS for comprehensive management.
SHARPv3 Integration: Supported with MLNX-OS and UFM Enterprise (externally managed).
- Top-of-rack leaf / spine in extreme-scale HPC clusters
- AI training and inference fabrics for deep learning
- High-performance storage and data analytics platforms
- Research & scientific computing (weather, genomics, physics)
- Cloud data centers with large-scale multi-tenant workloads
- Host Adapters: ConnectX-6, ConnectX-7 NDR
- Cables: OSFP passive/active copper, active optical, optical modules

Is this switch internally managed?
No, MQM9790-NS2F is externally managed. Requires a host-based Subnet Manager (UFM / OpenSM).
Can I change the airflow direction?
No, P2C (Front-to-Rear) is fixed. Choose -NS2R for C2P airflow.
Does it support SHARPv3?
Yes, with MLNX-OS and UFM Enterprise configuration.
What is the maximum port count at 200Gb/s?
Up to 128 ports using port-split technology.
- Confirm airflow orientation matches your rack cooling strategy.
- Use only NVIDIA-qualified OSFP optics and cables for NDR compliance.
- Ensure Subnet Manager is properly configured before connecting to fabric.
- Operating temperature: 0°C-40°C; maintain adequate ventilation.
- This switch supports 200-240VAC only - not compatible with 100-120VAC.
