I’m using Soft RoCE running on regular Intel 1G on-board NIC, and trying to connect to NVMe over RoCEv2 target. Linux software base NVMe/RoCEv2 target works fine so my setup should be OK but other native NVMe/RoCEv2 target doesn’t work.
Failed to write to /dev/nvme-fabrics: Connection timed out
NVMe/RoCEv2 target device supplier is saying, it could be because Soft RoCE specifies 0x80 in Responder Resources in ConnectRequest packet. It can only supports up to 64 (0x40). Is there a way to change parameter, Responder Resources in SoftRoCE.
I tried to set parameter from nvme-cli but it doesn’t change anything. And target supplier is saying it should be parameter in RoCE.
nvme discover -t rdma -a -s 4420 -Q 64
nvme discover -t rdma -a -s 4420 -i 64
I wonder it could be one of parameters under
based on the following website. But somehow I was not able to set/change parameter for it.
It doesn’t allow me to edit file.
Let me know if there’s any suggestion here…
I attached screenshot of wireshark packet.
Thanks in advance,
