sydsick Posted October 12, 2022 Share Posted October 12, 2022 I am at the limit of my understanding here, and I'm probably googling the wrong keywords. I was successfully able to get two mellanox Connectx-3's (mcx311a-xcat) to connect (windows 11 <-> Unraid) and transfer data at 10gb. This tells me the basic network setup should be correct. I swapped in a dual port Connectx-3 pro (MCX312B-XCCT) into the Unraid server, but I cant get it to work. I have seen one other Unraid user with this nic in their server, so I know it should be compatible, but idk what I'm doing wrong. I rebooted Unraid many times, reflashed the current firmware using the Mellanox CA plugin, swapped the nic to eth0 and back, but no dice. diagnostics-20221012-1341.zip Quote Link to comment
JorgeB Posted October 13, 2022 Share Posted October 13, 2022 No link being detected on either port of the Mellanox NIC, check cables/transceivers, could also be a bad NIC. Quote Link to comment
sydsick Posted October 13, 2022 Author Share Posted October 13, 2022 I'm guessing its a bad NIC since I can swap it with a single port mcx311a-xcat with the same cables/transceivers and it get a solid connection. Thanks! Quote Link to comment
