These are the release notes for the NVIDIA Quantum™-2 firmware. This firmware complements the NVIDIA Quantum switch with a set of advanced features, allowing easy and remote management of the switch.
This firmware supports the following protocols:
InfiniBand—SDR, EDR, HDR, NDR
This firmware supports the devices listed in the table below:
Model Number | Description |
QM9790 | NVIDIA Quantum 2 based NDR InfiniBand Switch, 64 NDR ports, 32 OSFP ports, 2 Power Supplies (AC), Standard depth |
This firmware version has been validated to work against platforms with the following firmware and software versions.
HCA/Switch | Firmware Version |
NVIDIA Quantum-2 | 31.2010.4010 |
NVIDIA Quantum | 27.2010.4010 |

Switch and HCAs InfiniBand Cable Connectivity Matrix
NVIDIA Quantum™ based switches and NVIDIA® ConnectX® HCAs support HDR (PAM4, 50Gb/s per lane) and EDR (NRZ, 25Gb/s per lane) technologies. As the ConnectX adapter cards are identified by their maximum supported throughput (e.g., ConnectX-6 VPI 100Gb/s card can support either 2-lanes of 50Gb/s or 4-lanes of 25Gb/s), the exact connectivity will be determined by the cable that is being used.
As a reference:
Speed Mode | Speed Supported | Number of Lanes Used |
NDR | 400Gb/s InfiniBand | 4 lanes of 100Gb/s |
NDR200 | 200Gb/s InfiniBand | 2 lanes of 100Gb/s |
HDR | 200Gb/s InfiniBand | 4 lanes of 50Gb/s |
HDR100 | 100Gb/s InfiniBand | 2 lanes of 50Gb/s |
EDR | 100Gb/s InfiniBand | 4 lanes of 25Gb/s |
The following tables present the connectivity matrix, between NVIDIA Quantum based switches, ConnectX HCA, and the cables.
Switch-to-Switch Connectivity
NVIDIA Quantum-2 switches come with OSFP cages. NVIDIA Quantum and Switch-IB 2 switches come with QSFP cages. The connectivity matrix below are separated into multiple tables due to the above physical differences between the switches.
