Greetings!
Windows server 2022 offers an RDMA based file transfer protocol SMB-Direct, and it can be used out of the box.
However, after installing server 2022 in esxi8.0 and assigning an SR-IOV VF virtual adapter to the VM, I discovered that it did not use SMB-Direct to transfer the file. As you can see in this picture, the VM have no RDMA traffic. The tcp ip traffic shown in the task manager further proved that the VM is not using SMB-Direct.
I tried checking the RDMA adapter in the VM, it did show RDMA enabled, and operational, but no PFC nor ETS.
Did I miss something? Please advise.
