Firmware Compatible Products

These are the release notes for the NVIDIA® ConnectX®-7 adapters firmware Rev 28.36.2020. This firmware supports the following protocols:

  • InfiniBand - NDR200, NDR

  • Ethernet - 1GbE,10GbE, 25GbE, 40GbE, 50GbE1, 100GbE1, 200GbE2

  • PCI Express 5.0, supporting backwards compatibility for v4.0, v3.0, v2.0 and v1.1

1. Speed that supports both NRZ and PAM4 modes in Force mode and Auto-Negotiation mode.

2. Speed that supports PAM4 mode only.

Warning

When connecting an NVIDIA-to-NVIDIA adapter card in ETH PAM4 speeds, Auto-Neg should always be enabled.

Switch and HCAs InfiniBand Cable Connectivity Matrix

NVIDIA Quantum™ based switches and NVIDIA® ConnectX® HCAs support NDR (PAM4, 100Gb/s per lane), 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 or by manual configuration.

As a reference:

VPI Protocol Support

ConnectX-7 supports having one port as InfiniBand and the second port as either InfiniBand or Ethernet.

To set the right configuration, run:

Copy
Copied!
            

mlxconfig -d <mst device> s LINK_TYPE_P1=1/2 LINK_TYPE_P2=1/2

where:

  • LINK_TYPE_P2 - sets the configuring protocol for port 2

  • (1/2) - values used for the different protocols:

    • 1 – for InfiniBand

    • 2 - for Ethernet
