    Buy the Mellanox ConnectX-4 on Ebay ebay.us/yT26fp (affiliate link).
    Sorry the audio is out of sync on the webcam overlay. Apparently my recording software messed up and didn't realize until I had the entire thing completed. I'll be using OBS next time for sure!

    Many thanks for this tutorial. My MCX455A-ECA cards FW upgraded as well without any issues.

    Good afternoon You are doing a great job! thereby making life easier for the engineer! Thank you!
    I have an unusual case, I want to make a small (small) board that connects 2 DAC passive cables at 100GB speed. The card is the same, only with 2 ports.
    But I can't get the host system to work through my board and 2 DAC passive cables. The DAC cable is 50cm long. The lines on the board are 15 cm long; there is an overlap of RX TX signals on the board.
    Tell me where to look? Who did something like this?

    What LC Transceivers are compatible with these nics?

    • @HomeSysAdmin
      @HomeSysAdmin  ปีที่แล้ว +2

      I didn't do any testing with tranceivers, mostly due to the cost of the tranceivers themselves. I would check fs.com, they have a nice listing based on brand/speed/connection/etc

    I didn't see your ground strap while handling that card....LOL why would you need 100Gb/s NIC (beside because I can)? In what application (moving files?) I enjoy all the different commands. Happy New Year. Thanks for sharing.

    • @HomeSysAdmin
      @HomeSysAdmin  ปีที่แล้ว +5

      I haven't seen anyone using wrist ground straps since... 1995? Is that still recommended practice? I don't think there's much logical reasoning for 100GbE in a home lab network aside from fun/learning honestly. Several reasons for an enterprise, and especially interconnecting high-bandwidth switches. Happy new year!

    Silly question. But changing these cards fro IB to Ethernet is a setting that is saved on the card itself correct? I plan on buying a few of these and it will be easier to update the firmware / adjust the settings in my office before I take them out to the different sites to install them in the servers.

    • @HomeSysAdmin
      @HomeSysAdmin  ปีที่แล้ว +1

      Not silly at all and yes, it's stored on the card itself so you can configure it on one server then move it to another.

      @@HomeSysAdmin So just to be clear - you can pop this into a Windows machine update the firmware, make the switch to Ethernet and then pop it back into a TrueNas server and the settings would be saved?

    Awesome guide. Question: I have a MCX-311A installed on my Synology NAS 1621+ that I need to install the latest firmware on. I installed Ubuntu as a VM on the Synology and installed the mst firmware utility along with the firmware image. When i do lspci, it sees the card as a “virtio” card not as a Mellanox card, hence the mst utility does not recognize anything and cannot proceed with the FW install. I was reading that in order to pass the pcie to the VM, you need hardware support (SR-IOV), which seems that my 1621+ does not support. So, i guess that is game over..?

    Can I buy 2 of this product and connect them directly with each other? 1 or 3 meters which type of cable is used. Can I run one to my Windows 11 computer and the other to True Nas, or openmedia vault?

    • @HomeSysAdmin
      @HomeSysAdmin  ปีที่แล้ว +2

      Yes, you can buy two of the ConnectX-4 and simply run a cable between them. I'm not sure if you need a special DAC or not, but I know if you're using optics, you simply need to swap the tx/rx on one side. You would also have to assign manual IPs since there is no switch nor DHCP.

      @@HomeSysAdmin My NAS device Raid 5 Mechanical Disk Will this create a bottleneck? So the disks must be SSD in order to see 100gb nic? For example, the system you show in this video is your nas system, what kind of disk structure do you use with SSD, Nvme, Mechanical Disk.

      @@techdocstr It's unlikely the network would ever be the bottleneck with 100gbps. That's over 12GB/s, even an array of NVMe drives wouldn't be able to keep up writing that quickly.

    I understand that at the ends of the DAC cable there is an EEPROM and it says who I am. Question - does the NIC card ports reading the eeprom compare it to the eeprom on the other end of the cable?
    I connected 2 DAC cables through a docking board (QSFP28 QSFP28) and can't get a connection between NIC cards
    I don't understand what's wrong.

    I wonder how much cpu usage and watts it requires in ethernet vs infiniband. What kind of cables and what can be connected to the other end of the cables when in ethernet mode (or is ethernet software done over infiniband?).
