Esxi 7.0 installation supports mellanox technologies mt26448 [connectx en 10gige, PCIe 2.0 5gt/s] driver, and supports the cheapest 10GB dual fiber network card

esxi 7.0 Installation support Mellanox Technologies MT26448 [ConnectX EN 10GigE, PCIe 2.0 5GT/s] Drive support The cheapest 10GB Dual fiber network card

    Recently deployed for two days esxi7.0 u3 Test server for , Install test licensed esxi 7.0, Turn over the box and find it 2 Zhang Double network port 10Gb Optical fiber pci network card , Want to use it , Results after installing the system , Do not recognize this network card information , I found a lot of information on the Internet , Didn't say how to solve , But when I turn to a foreign post , Found the specific implementation logic

First step ： Download the driver of the current network card

nvidia vmware Driver download address    vmware 7.0 nmlx5_core 4.19 Download address

  The second step stay esxi7.0 Install the current driver

        A lot of people say , It should be over here , After installing the driver, restart it , But it's a pity , The current network card is not recognized , How to solve ？ The answer is simple , modify esxi This drive , newly added Mellanox Technologies MT26448 equipment ID Into the drive

        Let's start with a piece of esxi Plug in the network card and start pci Identifying information pictures

        Basic operation ： Turn on esxi ssh visit

      Basic operation ： adopt ssh The tool uploads files to the storage directory （ You can also upload directly on the web ）

    Basic operation ： adopt ssh Software （putty） Carry out orders

          Operation and maintenance leaders can start from here , The front can be ignored , General basic operation , But we still don't understand the feedback , Re edit the added screenshots  

         1、 Pay attention to the key path ：/vmfs/volumes/62a5dccb-db34b016-9f24-ecf4bbf0e33c, The current path needs to be based on itself esxi datastore Path replace the following script

        2、Mellanox Technologies MT26448 equipment ID 0x6750

        Install the driver by command

esxcli software vib install -d /vmfs/volumes/62a5dccb-db34b016-9f24-ecf4bbf0e33c/Mellanox-nmlx5_4.22.71.1002-1OEM.703.0.0.18644231_19713367.zip

The third step Modify the driver and add Mellanox Technologies MT26448 Support

        Here is the focus of this article at the beginning , It is also a technical difficulty , Disassembly analysis , I think it's the following steps

The first step is unpacking esxi Driver file

The second step is to modify the driver description file , Add the current network card description

Step 3 repackage esxi drive , Replace the original driver

gzip output.vtar
mv output.vtar.gz nmlx4_co.v00
rm FILE.tar
cp  /vmfs/volumes/62a5dccb-db34b016-9f24-ecf4bbf0e33c/nmlx4_co.v00 /bootbank/nmlx4_co.v00

restart On the physical network card Found the device , If not , Take a closer look at the code above , Are there any mistakes , Or the replacement directory is not ready
