slipstream Posted January 23, 2021 Share Posted January 23, 2021 Hi All, I am new to UnRaid. I purchased a Mellanox MCX311A-XCAT nic card for my SuperMicro X10SRH-CF Motherboard. The Mellanox PDF manual has Linux Driver installation instructions but nothing for the UnRaid OS. Can anyone in the community please explain to me what is the correct driver I need to use so my Mellanox MCX311A-XCAT nic card works correctly in my UnRaid OS? Additionally, how are such drivers installed in the UnRaid OS? Are drivers in the UnRaid OS installed as plugins? Any clarification will be welcomed. Thanks. Quote Link to comment
Vr2Io Posted January 23, 2021 Share Posted January 23, 2021 No extra driver need with Unraid, pls check does cable, firmware, sfp+ issue. Quote Link to comment
tjb_altf4 Posted January 23, 2021 Share Posted January 23, 2021 (edited) I've got the dual port version, works out of the box, just make sure to setup and enable in the network section of the Unraid GUI. However, if you need easy access to the Mellanox tools, such as for flashing the cards bios, there is also a plugin available from version 6.9.0 onwards (or with 6.8.3 with custom kernel). The plugin can be found in Community Applications. Edited January 23, 2021 by tjb_altf4 Quote Link to comment
slipstream Posted January 23, 2021 Author Share Posted January 23, 2021 Thank you to all for your help. Just a follow-up question. The graphic below is from my SuperMicro X10SRH-CF Motherboard Owner's Manual. As you can see it has both PCH (Platform Controller Hub) and CPU labeled PCI slots. Does the UnRaid OS work better with my Mellanox MCX311A-XCAT card by inserting it to the PCH PCI slot or the CPU PCI slot? In short, what is the best PCI Slot Number I should use shown in the graphic below? Quote Link to comment

Always use CPU PCIe for best performance, usually lack of slot or IOMMU group issue will use PCH PCIe Quote Link to comment
slipstream Posted January 23, 2021 Author Share Posted January 23, 2021 Thanks for your post. It looks like my choices have narrowed down to using either Slot 4, 5 or 7. Slot 6 looks like it is for video card use so that one is out of the picture. Thanks for your help. Quote Link to comment

slipstream Posted January 23, 2021 Author Share Posted January 23, 2021 Vr2lo, I noticed while my UnRaid OS was working through the bootup process there were several lines that mentioned Mellanox. So at the least I can say my UnRaid OS is recognizing my Mellanox card and went through some kind of internal setup for it. However, the problem is my Windows RAID5 PC which holds the data I want to migrate over to my UnRaid PC. The Mellanox card setup on my Windows PC seems to have a problem. I think for now I'm trying a different approach which is doing a peer to peer CAT6 cable connection between both PCs using only the LAN ethernet port already included in the two separate motherboards. I will make a different post to cover this new approach. Quote Link to comment
