Known Issues & Troubleshooting

As with any complex hardware device, some issues may arise when installing or operating the NVIDIA Mellanox MCX654106A-HCAT SmartNIC. The most common issues and their resolutions include:

• Driver compatibility issues - Ensure that the latest driver for your operating system is installed, and that the compatibility between the NICs and drivers is certified, to avoid issues related to intermittent performance, ports not being detected, and other compatibility-related issues.
• Firmware upgrade issues - Check the latest firmware version from Mellanox and refer Mellanox product release notes, as upgrading can cause system instabilities and reboot or device failure.
• Performance/bandwidth issues - Attend to your NIC datasheet specifications and its implementation configurations to ensure optimal performance is being achievable.
• Telemetry issues - Ensure that your sensors or applets are receiving data from your and configure your processing at your endpoint accordingly. Sometimes, separate hardware or NIC utilities, such as MLNX utility may be required to extract specific telemetry data for issues.

Driver

The driver for NVIDIA Mellanox MCX654106A-HCAT SmartNIC may vary according to the operating system (OS) that you are running. You must use an up-to-date driver that is certified as compatible with your NICs firmware version and OS type.

You can normally download the latest driver from the manufacturer’s website, and install it manually during driver setup. Another option is using Mellanox/Solarflare and other leading hardware driver package deployment tools or device management suites.
