RDMA is not activated on my Mellanox ConnectX-2 Card?

Hello, I cannot activate RDMA on my 2 Mellanox ConnectX- MNPA19-XTR Cards and I get low speeds. How can I activate this on Debian 11 and Windows side.

Hello techdocstr,

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

Based on the info provide, the MNPA19-XTR is a 10Gb/s adapter. Also this p/n is EOL and EOS for a long time and driver support is not always available in the newer OS versions. Also RDMA functionality between Linux and Windows is very limited.

It is always between Linux ↔ Linux, and Windows <->. There is currently no such tool available to measure RDMA performance between Linux and Windows, nor is it on the roadmap.

Thank you and regards,
~NVIDIA Networking Technical Support
