Yes, this works and has been deployed. SM should take care of setting up the links properly and the PathRecords returned should set parameters for the paths for the QP connections between the HCA endpoints.

Subject: [openib-general] mellanox sdr/ddr hca interoperability
Can I build a fabric with a ddr switch and some hosts with sdr hcas, and other
hosts with ddr hcas?
Are there known interoperability issues with such a fabric? All transports (ud/
rc) work as expected?
For example can a ddr host establish a connection with a sdr host and send/
receive data? Should I configure anything specifically for such a fabric?
