    ConnectX-2 Firmware / Performance?


      Hi this is my first Post and my first venture in to the 10G World, I picked up 2 - ConnectX-2 Cards and installed them in two Hyper-V Servers to use as a private network connection for live migrations until we can get a 10G Switch (So these are connected together directly).


      With this in mind I downloaded what I believed was the latest version of software / driver that supports the ConnectX-2 Cards (MLNX_VPI_WinOF-4_80_All_win2012R2_x64). The driver installs properly and I can see all of the information in the properties tab.


      I am however getting two (make that 3) different messages in my event viewer and wonder were I can get the updated firmware that is mentioned. Here are the two entries I am seeing.


      The firmware version that is burned on the Mellanox ConnectX-2 Ethernet Adapter device does not support Network Direct functionality. This may affect the File Transfer (SMB) performance. The current firmware version is 2.9.1200 while we recommend using firmware version 2.9.8350 or higher. Please burn a newer firmware and restart the Mellanox ConnectX device. For more details about firmware burning process please refer to Support information on http://mellanox.com


      Mellanox ConnectX-2 Ethernet Adapter device reports that the "QOS (ETS) capability is missing". The current firmware does not support the QOS (ETS) capability. Please burn the latest firmware and restart your machine. (The issue is reported in Function SetHardwareAssistAttributes).


      The File Transfer (SMB) performance may be affected as Network Direct functionality is not supported in ConnectX-2 firmware version.


      Keep in mind that the connection is working, I am seeing about 2.5Gb/s transfers between the systems which I can't complain about but was wondering if I can get better?


      Thanks in advance.
