Product overview
The NVIDIA Quantum‑2 MQM9790‑NS2R is an unmanaged 1U switch offering 64 ports of 400Gb/s NDR InfiniBand. It delivers an aggregate bidirectional throughput of 51.2 Tb/s and more than 66.5 billion packets per second. Designed for extreme‑scale AI and HPC, it integrates third‑generation NVIDIA SHARP (SHARPv3) in‑network computing, boosting AI acceleration up to 32× compared to prior generation. This model features connector‑to‑power (C2P) airflow, is ready for NVIDIA UFM advanced fabric management, and supports flexible topologies (Fat Tree, DragonFly+, Torus, SlimFly).
Unmatched performance
64 non‑blocking 400Gb/s ports, 51.2 Tb/s aggregated throughput, 66.5 BPPS. Port‑split technology enables 128 ports of 200Gb/s for double‑density top‑of‑rack deployments.
In‑network computing SHARPv3
Third‑gen NVIDIA SHARP technology accelerates collective communications. Data aggregation happens inside the fabric, reducing traffic and delivering up to 32× higher AI acceleration than previous generation.
NVIDIA SHARPv3 technology
The MQM9790‑NS2R embeds the third generation of NVIDIA Scalable Hierarchical Aggregation and Reduction Protocol (SHARP). By offloading data reduction operations (all‑reduce, broadcast, etc.) to the switch fabric, SHARPv3 dramatically cuts inter‑node traffic and reduces application runtime. This in‑network computing capability is essential for massively parallel AI training and complex HPC simulations.
Typical deployments
- Large‑scale AI supercomputers (LLM training, simulation)
- High‑frequency financial modeling and risk analysis
- Multi‑tenant cloud HPC with isolated fabric partitions
- Research labs with hybrid Fat‑Tree / DragonFly+ topologies
- Enterprise core for data‑intensive workloads (genomics, climate)
Compatibility
- Backward compatible with 200Gb HDR, 100Gb EDR, and previous InfiniBand generations
- Interoperable with NVIDIA ConnectX‑6, ConnectX‑7, and BlueField‑3 DPUs
- OSFP connectors: passive/active copper, active fiber, optical modules
- MLNX‑OS software suite (used internally); UFM management ready

Buyer checklist
- ✔ Confirm airflow direction C2P matches your data center hot/cold aisle.
- ✔ Verify power input (200‑240Vac) and redundancy requirements.
- ✔ This is an unmanaged switch; plan to use NVIDIA UFM for advanced management.
- ✔ For 128 ports of 200G, ensure your cables/optics support split‑mode.
- ✔ Check compatibility with existing HDR/EDR infrastructure.
Why choose Quantum‑2
Highest radix 1U 400G switch with 51.2Tb/s capacity. SHARPv3 in‑network computing reduces job completion time. Self‑healing network, QoS, adaptive routing, and enhanced VL mapping. Energy‑efficient design lowers OPEX.
Service & support
1‑year limited hardware warranty (extendable). Advanced replacement available. 24/7 technical support through Hong Kong Starsurge Group. Firmware updates and UFM licenses available. Please contact our sales team for exact terms.
Frequently asked questions
Important notes & precautions
- Install only in a rack with adequate airflow – ensure fan trays match your C2P direction.
- Use only supported OSFP modules (passive/active copper or optical) listed in the compatibility matrix.
- Power input must be 200‑240Vac; not compatible with 110V.
- Operating altitude up to 3050m; derating may apply above 1800m.
- Some specifications (e.g., exact CPU model, SSD size) are typical but may change; confirm with order.
