    SFP-10G-T for Mellanox?

    I received a 10gtek 10baseT SFP today from amazon that is coded for Mellanox and it works fine in the card. So, it is definitely vendor lock.

    SFP-10G-T for Mellanox?

    Interesting. I'm curious to see if it is a brand lock thing or something else. I have a 10gbaseT model that claims to be coded for Mellanox on the way for testing.

    SFP-10G-T for Mellanox?

    I'm not sure if they are compatible or not, that's why I'm posing the issue here :) Hoping those more experienced with Mellanox than I have an answer. Mellanox lists the card as able to use SFP+ and SFP28. MLX5CMD indicates the below, so it seems to recognize it, but windows still shows the...

    SFP-10G-T for Mellanox?

    I have 6com SFP-10g-T modules, they work in both my ubiquiti switch and my extreme networks switch. They don't seem to work at all in the Mellanox MCX4121A-ACAT cards I have. Can anyone recommend SFP-10G-T modules that are known to work? Thanks,

    Mellanox ConnectX-4 CX4121C firmware

    I was trying to get the Mellanox firmware not dell, as the dell firmware won't work in a non dell system. MCX4121A-ACAT seems to have been the answer it seems to have flashed correctly.

    Mellanox ConnectX-4 CX4121C firmware

    Awesome! I found a reference on fs.com that indicated that was it, but wasn't definitive. So, the Huawei link is at least a corroboration.

    Mellanox ConnectX-4 CX4121C firmware

    Is there a way to find that in linux without having the mellanox tools installed? It's currently in my XCP-NG box which doesn't have all of the dependencies available to install the tools in XCP repositories.

    Mellanox ConnectX-4 CX4121C firmware

    I picked up a couple of Dell/Mellanox dual port 25g cards and they are listed as CX4121C, and the dell .bin file for updating firmware says my system is not supported. Anyone know what the equivalent mellanox model number is? Thanks,

    Flashing stock Mellanox firmware to OEM (EMC) ConnectX-3 IB/Ethernet dual-port QSFP adapter

    I'm relatively new to the 10g plus networking world. Are these Mellanox MCX354A-FCBT cards able to do 25g? I just picked up a Unifi switch that has 4 25g ports.

    H11dsi won't boot from m2 ssd

    I have an H11dsi motherboard, it won't boot from the m2 ssd on the motherboard. I updated the BIOS to support my epyc processors and now it doesn't see the m2 SSD. I assume this is due to the BIOS being cleared. Anyone know what options I need to set to get this to boot from the M2 ssd? Thanks,

    Flashing stock Mellanox firmware to OEM (EMC) ConnectX-3 IB/Ethernet dual-port QSFP adapter

    With these cards if I buy a QSFP+ breakout cable to 4 SFP's, how do the connections work? Do I setup a lagg bond on the switch with the four SFP's? Does the NIC see all four SFP breakouts as separate connections? I don't have a cable yet, and have never used one so forgive my ignorance.

    Flashing stock Mellanox firmware to OEM (EMC) ConnectX-3 IB/Ethernet dual-port QSFP adapter

    I connected my NAS to the same ports, with the same cables. I was able to get it working I had to get QSFP to SFP adapters and use SFP's, per this article ( Using a 40GbE (QSFP+) NIC with a 10GbE Switch (SFP+) (servethehome.com). I am not terribly familiar with 40gb Ethernet, however I was...
