The NVIDIA QM9790 (part number 920-9B210-00FN-0D0) is an NDR InfiniBand switch from the NVIDIA Quantum-2 series. This unmanaged switch provides 64 NDR ports delivered through 32 OSFP connectors, giving a high port count in a single switch for InfiniBand fabrics.

This model uses P2C (port-to-chassis) airflow, so cooling air moves from the port side toward the chassis side. Matching the airflow direction to the rack's hot-aisle and cold-aisle layout helps keep thermal conditions consistent in the data centre. The configuration listed includes rail mounting for installation in a standard equipment rack.

NDR InfiniBand switches such as the QM9790 are typically used to interconnect servers and storage in high-performance computing clusters, AI and machine learning infrastructure, and other environments that require high-bandwidth, low-latency networking between compute nodes.
