MQM9790-NS2F – HDR 200Gb/s Modular InfiniBand Switch for High-Performance AI & HPC
The NVIDIA MQM9790-NS2F is a director-class, modular InfiniBand switch platform aimed at organizations building or expanding large-scale HPC and AI interconnect fabrics. With HDR 200Gb/s port speeds and a modular chassis design scalable to 800 HDR ports, it suits hyperscale data centers and enterprise compute clusters where fabric capacity must grow in stages. Buyers should plan for full-rack deployment space and front-to-back airflow alignment with the facility’s hot/cold aisle layout.
Key specifications (table)
| Parameter | Specification |
|---|---|
| Model / Part Number | MQM9790-NS2F (920-9B210-00FN-0D0) |
| Brand | NVIDIA (Mellanox InfiniBand family) |
| Switch Architecture | Modular, director-class |
| Maximum Bandwidth | Up to 320 Tb/s switching capacity (chassis total, configuration dependent) |
| Port Speed | HDR 200Gb/s per port, QSFP56 |
| Maximum Ports | Up to 800 HDR ports via modular line cards (scaling depends on card configuration) |
| Latency | Sub-microsecond port-to-port latency |
| Hot-Swappable Components | Fans, power supplies, and line cards |
| Management | Mellanox UFM, CLI, SNMP, REST API |
| Cooling | Front-to-back airflow with redundant fan modules |
| Power Supply | Redundant, high-efficiency design |
| Form Factor | Large chassis (director switch) for enterprise or hyperscale environments |
Good to know
- Verify that HDR-capable adapters (e.g., HDR HCAs), QSFP56 cabling, and rack power/cooling budgets are in place before deployment — director-class chassis require significant provisioning.
- Within NVIDIA’s InfiniBand lineup, this modular director platform sits above fixed-configuration switches, offering line-card-based expansion for fabrics that outgrow single-chassis designs.
- For export orders from Shenzhen Huaqiangbei, confirm the exact part number (920-9B210-00FN-0D0), line-card population, and power cord region with your account manager before committing to a lead time.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
