These are the release notes for the NVIDIA Quantum™ 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, QDR, FDR EDR, HDR
This firmware supports the devices listed in the table below:
Model Number | NVIDIA SKU | Description |
MQM8790 | 920-9B110-00FH-0D0 | NVIDIA Quantum 40-port Non-blocking Externally Managed HDR 200Gb/s InfiniBand Smart Switch |
This firmware version has been validated to work against platforms with the following firmware and software versions.
HCA/Switch | Firmware Version |
NVIDIA Quantum | 27.2010.4210 |

Cables and modules that are not listed in this section may not work and will not be supported by NVIDIA.
Switch and HCAs InfiniBand Cable Connectivity Matrix
NVIDIA Quantum™ based switches and NVIDIA® ConnectX®-6 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 |
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 |
FDR | 56Gb/s | 4 lanes of 14Gb/s |
The following tables present the connectivity matrix, between NVIDIA Quantum based switches, ConnectX-6 HCA, and the cables.
