August 11, 20241 yr Hi, I got one Dell BCM957810A 10Gbps NIC recently. It works properly in Windows. But after I put it into my HPE Microserver Gen10, it totally can not work. Unraid shows nothing in the "Network settings". But when I check the System Devices. It seems Unraid can discover the hardware correctly. I tried to add "pci=realloc=off" in the boot option. No help.

But I cannot find anything online with these keywords.

One PCIE 3.0 x8 and One PCIE 3.0 x1. So my setup is to put the "Dell BCM957810A 10Gbps NIC" in the x1 slot. And leave the x8 slot to the SN640 SSD via a m.2 adapter. Firstly I thought it may be a PCIE bandwidth issue. So I tried the so-called minimum hardware bootable solution. Which I removed all my hard disks including this SN640 and put the 10G NIC into the PCIE3.0 x8 slot. Still, the same problem shows up. I searched a lot online. It seems Unraid has no issue with this NIC right? Can anyone help me to take a look? Really appreciate. Thanks, unraid-diagnostics-20240811-2003.zip

To see if it's a compatibility issue.

To see if it's a compatibility issue. Hi JorgeB, The NIC does work on another PC in Windows. plug and play. My test env is a bit weird. It looks like an external Graphic card dock. The workstation is a mini PC called beelink ser7 which has no PCIE slot. But it has 2 USB4 40Gbps ports. Later, I used an external hard drive enclosure(Using ASM2646 chips), which converts USB4 to M.2. To me, NVMe is just a different form compared to PCIe. Later, I used an M.2 to PCIe slot adapter to finally turn the hard drive enclosure into an external PCIe slot. I tested this NIC together with another x540 NIC with it, and they were correctly recognized and plug-and-play. (It also required an additional 12V power supply, but this is not related to the conversion.)
August 14, 20241 yr Community Expert I'm afraid that probably not much can be done if the NIC fails to initialize with that server, it would probably work in a normal PCIe slot.

In Windows or in MacOS. When using this ASM2646 dock. X540 works in windows and MacOS, plug and play. Dell BCM957810A 10Gbps NIC only works in Windows. Although I've only tested these NICs, M.2 SSD, but I'm sure it can support graphics cards as well, as I've also tested NICs with an external 12v power supply. Im sure M.2 drive enclosures using this ASM2646 chip will become the cheapest external graphics card dock~ Ok. Now come back to my NIC issue. I still can not figure it out. Besides what JorgeB said above, is it possible that some setting in the BIOS is affecting it? Edited August 15, 20241 yr by dtsnas
August 16, 20241 yr Note that, may be simple try below command ( also others ) and check does NIC discovery or not. modprobe thunderbolt-net https://www.kernel.org/doc/html/v6.2/admin-guide/thunderbolt.html Edit : The chip should be ASM2464 not ASM2646. Edited August 16, 20241 yr by Vr2Io
