Crossover connection with ConnectX-5 NIC

Hello,

I remember it was possible to connect Connectix-3 NICs (RoCE) crossover without a switch when installing the required WinOF driver. (ConnectX3 directly connected without switch)

Is this still possible with ConnectX-5 cards?

Thanks!

Hello cnschindler,

Thank you for posting your inquiry on the NVIDIA Developer Forum - Infrastructure and Networking - Section.

Yes, you can create a back-2-back connection between the ConnectX-3 and the ConnectX-5 adapter based on a supported cable between the two of them.

You can find the supported cables for the ConnectX-5 adapter in the following URL → Firmware Compatible Products - NVIDIA Docs

and for the ConnectX-3 → https://network.nvidia.com/pdf/firmware/ConnectX3-FW-2_42_5000-release_notes.pdf

Thank you and regards,
