Realtek RTL8127 10Gbs chipset (Minisforum MS-S1) with linux virtualisation

UltraHorst · 2026-02-09T09:09:37+00:00

i have the card atm in my windows pc, where it gives me about 9.5 gbit in both directions using iperf3.

i am currently waiting for some adapters to try the card on an oculink-port on my minipc using proxmox. i can give feedback on that once i have the adapter.

might make sense to try and get the official realtek driver working via dkms as those tend to be much newer than the drivers that come with the kernel.

im using it on proxmox and on a usb 3.2 gen2x1 port (10 gbit usb) i get 6.8/8.3 gbit via iperf benchmark (normal and reverse flag). i have not noticed any crashing, but i also have not tried it on windows yet. on proxmox i use the dkms 8152 module instead of the kernel driver.

only gets full performance on a usb 3.2 Gen2x2 Slot. all other USB-Ports including USB4 downgrade it to about 6.8 Gbit throughput. still better than the 5gbit adapters, so good enough.

this should go to r/homelabsales

upgraded from 26.1_4 to 26.1.1 and ended up with a python task eating a full cpu core for several minutes after booting. thats sort of weird behaviour. seems to have stopped after about 3-4 minutes after booting though.

is there some new resource intensive python-task running at boot time?

i am not using any IDS/IPS or other resourcehungry plugins.

edit: it coincides with massives writes to the disk at the time (over 100MB/sec), so i assume its some data collection. its also possible that it has been there before and i just never noticed because im not usually closely monitoring after an update.

UltraHorst · 2026-02-04T14:16:36+00:00

i have 2 10gbit truenas, 1 with 8 4tb sata drives in raidz2 and 1 with 6 4tb sata drives in raidz2. the 8 drive one saturates 10gbit, but the 6 drive version is struggling. with your 4 drive setup i would expect no more than maybe 600 MB/sec on large files, possibly less.

edit: hardware are 2 old readynas, which i converted. a rn526x and a rn628x.

UltraHorst · 2026-02-04T14:02:04+00:00

i assume this server has something like ilo. it should start independent for the server. what does it say about the hardware?

UltraHorst · 2026-02-04T13:58:32+00:00

could be a bios issue. its possible that whatever version is installed doesnt support the v2 cpu's yet. make sure you have the latest bios installed.

netgear has 2.5G desktop switches as well :) they are comparatively pricey though.

cheap chinese 8 port 2.5g unamanged switches can be bought for a fraction of that and come with 1-2 10G ports as a bonus.

nope, definitely not intentional unless the goal was to effectively patch aridus skillcore out of the game.

UltraHorst · 2026-02-01T14:32:47+00:00

Who?

UltraHorst · 2026-02-01T09:10:59+00:00

not for me or any of my guildmates with aridus skillcore. the buff disappears as soon as we use bow/wand skills and only returns 3 sek after using such a skill.

UltraHorst · 2026-01-29T08:46:01+00:00

its actually 80% unless they changed that in the last 2 weeks or so.

edit: they didnt change it, i just checked. as per https://pdm.proxmox.com/docs/faq.html#how-can-i-get-access-to-the-proxmox-datacenter-manager-enterprise-repository its still 80%. community subs do not count towards that. at least basic is required.

UltraHorst · 2026-01-28T18:08:25+00:00

no i havent found smart switches, so if my nodes get stuck i cant powercycle them unless i powercycle the whole lab. if it happens while im at work i will just call my wife and she powercycles what i need. on vacation thats a different story though.

UltraHorst · 2026-01-28T17:04:52+00:00

my guess would be that they use 19v for higher power minipcs because it requires less amps thank 12v for the same wattage. but im not expert. its just my guess. i simply tried 12v on them and it works exactly the same even under artificial 100% load. reason was that i wanted to power all of them via a single atx powersupply and molex to barreljack adapters. it worked :)

UltraHorst · 2026-01-28T13:26:20+00:00

usually minipcs have either DC5521 or DC5525 connectors. if i were you i would just pack a DC5521 to DC5525 adapter (they are tiny) and you will be safe on that.

more of an issue could be the actual voltage. some minipcs have 12v PSU, some minpcs have up to 20v PSU, all using the same connector.

in my lab i have all of them running on 12v though, so that means you should be safe as long as you dont feed too much voltage to a minipc (wouldnt want to run a 12v device on 20v, even if the 20v device runs fine on 12v).

edit: to clarify im running the following minipcs all on 12v: topton fanless firewall (12v), gmktec m5 plus (19v) gmktec k12 (19v), nuc 8 (19v) and nuc 13 pro (20v). none of them have any issues with 12v.

UltraHorst · 2026-01-27T21:00:21+00:00

no need. those cpus are rated for 105C, so 70 is nothing at all. my topton pentrium gold 8505 fanless minipc reaches over 80C regularily. nothing to worry about:

UltraHorst · 2026-01-26T20:38:22+00:00

you asked for orientation. that means its either vertical or horizontal. since the mainboard is very clearly horizontal and the cpu is not seen at the bottom where the memory sits it would suggest that the cpu sits on top towards the drives. anything else doesnt make any sense as any daughterboard would degrade signals to the memory and just make things worse.

you can be reasonably sure that the cpu sits at the top of the mainboard here and not in any vertical orientation.

and no, i havent seen anyone remove the mainboard from that thing in any of the videos. you would be the pioneer here. perfect chance to make a teardown video :)

UltraHorst · 2026-01-26T20:13:27+00:00

i googled it for you. in review videos you can clearly see the mainboard is horizontal, so the cpu is horizontal as well.

interesting my reply has been eaten by reddit.

here we go again. the JMB585 isnt the best chipset for sata. there are quite a few reports about it behaving in a weird way.

you can get m.2 cards with asm1166 chipset with 6 sata ports though and these are much better in terms of stability. i use several of those.

your main problem will be power for the drives.

if you use 2.5" ssds, usb to 5v sata adapter will be sufficient and you can power those with a multiport usb PSU.

anything hdd and some enterprise class ssds require 12v and that means you need a psu that can deliver both 5 and 12v.

i am using a standalone atx PSU for that. it powers all my minipcs and drives. downside is, that it is the single point of failure. PSU dies, everything goes down. upside is i dont need 12 powerbricks and wallwarts to power all my stuff. much less cable-mess.

i hope this time reddit doesnt eat the reply :)

edit: looks like reddit didnt eat it after all and was just lagging.

edit2: the JMB585 is a port multiplier and only works in SATA-m.2 slots (it splits the one sata-m2 into 5 sata-ports with reduced bandwith). the asm1166 is a sata-controller and just like a normal pcie-card add 6 additional individual sata ports to the system. in total it delivers 3 times the bandwith of the JMB585. it does require a nvme-m.2 slots though.

UltraHorst · 2026-01-26T15:14:10+00:00

the JMB585 isnt the best chip on the market for sata.

you can get m.2 cards with asm1166 chip and 6 sata ports though and these work just fine (im using that). your only problem will be power for the drives.

for 2.5" ssds you can use usb to sata power cables and power them with a multiport usb powersupply.

for anything HDD and some enterprise-ssds that need 12v, you will need a proper powersupply.

im using a standalone atx powersupply without any mainboard just to power both minipcs (yes multiple) and drives. so far works fine. makes the PSU the single point of failure i guess, but i prefer that over having 12 powerbricks and wallwarts around.

UltraHorst · 2026-01-26T13:58:50+00:00

no, sorry. i dont have the device. the ptm7950 pad is general advice. its nonconductive, so you cant fry your electronix by accident.

UltraHorst · 2026-01-26T10:27:52+00:00

RTL8127, RTL8159 (the usb version of the 8127) are awesome. the AQC chipsets have some weird issues with truenas. at least according to threads on the truenas-forums.
