    RoCE Mode equal to 1.25

    kmihalic

      Hello everyone,

       

      I’m configuring RoCE on Mellanox ConnectX-3 VPI (not pro). OS is Windows Server 2016 Datacenter (Core).

       

      And two commands report two different RoCE settings:

       

      Get-MlnxNetAdapterRoceSetting

       

      Name Description Enabled RoCE Mode

      ---- ----------- ------- ---------

      Mellanox1 Mellanox ConnectX-3 Ethernet Adapter 1.25

      Mellanox2 Mellanox ConnectX-3 Ethernet Adapter #2 1.25

       

       

      Get-MlnxDriverCoreSetting

       

       

      Caption : DriverCoreSettingData 'mlx4_bus'

      Description : Mellanox Driver Option Settings

      Can somebody could clarify this discrepancy, and what is RoCE mode 1.25

       

      Also from documentation, this card (Mellanox ConnectX-3 VPI) does not support RoCE v2.

      I used Windows Server 2016 to enable RDMA, have not changed RoCE mode in driver configuration, should I switch RoCE Mode to V1 ?

       

      Any help is appreciated.
