Realtek 8125B NIC and Truenas Scale build

Hi
I was looking at deploying a truenas scale on the following HW

  • Ryzen 5 3600
  • Asus TUF B550-Plus ATX
    (with realtek 8125B NIC)
  • G.skill DDR4 3200 CL16
  • Other existing parts such as a Seasonic core GC650 Gold PSU and a case with support for 6 3,5" HDD’s. And couple of 5.25" drives on top. And yes, it is ATX.

The main issue I was looking at was the NIC, with a quick search that the FreeBSD based versions of Truenas such as Core and Enterprise don’t support this currently. Based on a couple of searches, that version might be supported on 5.9.x kernel.

My quick source
https://linuxreviews.org/Realtek_RTL_8125

I might have looked at the wrong spot, but I couldn’t find the kernel version number. I checked the official docks as well. No luck so far.

Since it is based on debian 11, it could be from 5.14 to the latest versions available.

If you know something, please let me know!
Thank you for your time

supposedly it is ‘supported at 1gb only’ due to an old driver in use. also the performance of RTL drivers in Truenas is pretty bad.

an intel i-225 2.5gb, or an intel nc360 1gb nic are both under 20$ on ebay.

For my use case, the bandwith used is going to be limited by my gigabite LAN. The switches are from TP-link, semi managed SG108E variants.

So gigabit should be fine. But I might indeed end up going to get a second NIC. But looks like most of the local stuff availlable is realtek. Or unreasonable expensive…
And looking at ebay, most of the stuff is shipping from China.

I think @Zedicus you managed to answer my question.
Thank you for your time!

i’ll chime in here. i am using Truenas Scale and purchased a cheap 8125b rlt 2.5Gb NIC. ive tested this with Cobia. install the driver pack from the website for kernel build up to 6.4. You should know what you are doing here as you will be creating a new sudo user with dpkg install and wget to get the compiler packages you need.
Im not Linux savy but i am a Senior IT specialist from an MSP. i used chat gtp to help me with what i needed with best practice and was able to install the autoinstall.sh file without to much off an issue once compiler dependencies were met. the driver was effective immediately and perfoms up to 280MB/sec steady without issue. Leave the MTU to auto when using the tplink 2.5Gb switch and you will see it work without an issue. i dont come on here often. i just wanted to say i see a lot of people say a lot of garbage when it comes to this adapter. but i have ZERO issues with SMB or the KVM.
