ConnectX6 Socket Direct and VMware


I have problems with a Mellanox ConnectX-6 Socket Direct card under VMware 7.0U2. I just can’t get any communication established.

The card is connected via DAC cable to two SN2410b running Cumulus Linux. The port on the switch is configured as MLAG.

Does anyone know about these cards under VMware and can help, Mellanox support doesn’t know either.



Hello Daniel,

As we noticed some discrepancies within the documentation, we will continue to assist you through the official documentation.

Based on the VMWARE HCL, the ConnectX-6 Socket Direct adapter is not mentioned in the list. We are validating this internal, and will continue to update you through the support case.
