um, well, I very cleverly
decided to just not use that port. If someone has a better idea, or perhaps maybe did the correct thing (contacted support) pls let me know. No plans for using more than 2 ports for quite a while.

- Different USB Stick
- Etcher/Rufus
- Installing debian 12
I can access bios and i get the installer of OPNSense to run till main menu. But no look with ubuntu. Any ideas?

I found it easier to just buy a cheap VGA to HDMI adapter and use that.
I'd still be interested to hear if you are successful using the serial console installer though.
Yeah, no store in my local area and with online order it will arrive on tuesday ;(
EDIT:
Well, i got some progress. I changed
terminal_output gfxterm
to
terminal_output console
And now i get the dialog for proxmox, but now it's stuck on
Loading Proxmox VE Installer ...
Loading initial ramdisk ...

My workaround is cold boot without the sfp+, I have 4 sftp+ rj45 modules.um, well, I very cleverly
After it has booted I put the 4 in and reboot my Proxmox.
After this warm boot they work.
Fortunately this a 24/7 system , therefor cold booting doesnt happen often.
Meh, managed to install debian by modifying the grub.cfg. I was able to install the os, but afterwards im stuck on
This is the grub.cfg on the usb stick that at least made it possible to access OS installation
EDIT:
Nevermind, i dont get output put the system is working, i can connect via ssh. I will install proxmox on top of this, didnt managed to edit the proxmox installer to work on serial
Anyone got an idea?

Hi, I have just received today my Qotom with the C3758R where I have installed the latest version of opnSense 24.7.6
I am trying to understand what is going wrong with the bandwidth. I have only two SFP+ connected, one to a 10gbit internet router, and the other one to a mikrotik crs309.
My problem is that I can't get more than 5 Gbit/s throughput, so I started digging down into problems of cables etc.
Finally my last test left me speechless.
iperf3 -c localhost showing a maximum of 5 Gbit/s
I have tried then to boot ubuntu from a usb stick, and doing the same tests it has shown me a good 12.9 Gbit/s
Do you have any clue of what it could be at this point?
Please note that it's not a matter of cables or anything connected as the last tests have been done with no network cable connected, just me on the console.
Thanks,
Franc

Just got two of the (32GB RAM 1TB SSD, C3808) units for a XxxSense soft router and some 24x7 VMs.
Arrive in eastern US in five days.
Seems like a very cheap power supply and no-name ssd (Phison brand??)but that seems like it is always a crap shoot on what you get.
Waiting for a VGA cable. I can't believe I threw away a vga cable from my junk pile that I had for 20 years thinking I would never ever need a VGA cable :-(
I just noticed there is a fan but zero vents in the enclosure. Kind of defeats the purpose of the fan, no?

@HeneryH That looks like the same PSU STH got with their unit. Mine has a Channel Well Technology (CWT) PSU, which is a well known ODM and OEM of PSUs.
That fan looks new. Mine doesn't have a hole for a fan, and neither does the unit STH bought. Where did you order it?

I ordered from the AliExpress Qotom store.
Mini PC Q20300G9-S10 Series CPU Atom C3558 C3758R C3808, 10G SFP+/ 2.5G LAN/ Console/ VGA, Qotom Mini Server/ Router Firewall

$493.20

I'm thinking I should drill some vent holes in the enclosure to make the fan have at least some effectiveness. Otherwise it is just creating a low pressure or high pressure zone. Or just unplug it.
I always found that the price for included RAM/SSD isn't particularly good, so I always bought "known reliable" hardware locally, usually WD blue NVMe and micron/crucial memory. This always was *a lot* cheaper and IF there were any failures I can get it replaced in short time (never had any failure yet though...).
Regarding the power supply: the rackmount unit has a high quality MeanWell power supply. So if that's a concern, just go for the rackmount unit.
OTOH it is always highly possible that a "cheap noname" brick is actually the ODM variant of some "known brand". I have some allegedly "noname" bricks lying around that are exactly identical (case and internals) to the ones some intel NUCs came with.
Has anyone tested ECC dimms on these?
I wanted to maybe pickup some here if they are supported, only 2133MT.. hopefully not leaving too much performace on the table.

Have 64G ( 2 x 32G SK Hynix HMAA4GS7AJR8N-VK ) ecc unbuffered modules; the ones in the Qotom mem qual list. Bought them from newegg some time ago, They work fine however they were expensive and, for two of them to work, had to lower ram speed to 1600. Would not run both at 2400. Tested with latest passmark memtest identified correctly and with ecc. Tested ok. Some pages back someone else mentions some ecc modules that work as well and are cheaper.

Alright, finally Proxmox updated the SPF+ port issues but now I can't get them to work with my DAC's or (expensive) 300mtr SPF+ RJ45 Ubiqity
I have both copper and fiber DACs but none seems to make connection. Anybody willing to share which DACs do work? I prefer the fibers because they stay a bit cooler (living in the tropics).
Tested with Mikrotik switches and a MS-01 Minisforum.

I doubt you have a 300m SFP+ RJ45 transceiver, no matter how expensive.
I use my Qotom box with a H!Fiber CAB-10GSFP-P2M 2m passive DAC (manufactured by 10Gtek).
The passive DACs should run cooler than fiber AOC cables (which it sounds like you are talking about) since they don't need any active transceivers, unlike any other type of cable.
My CWWK-made 6-port one came with the same brand PSU as this STH review: "Dajing".
Probably "Dajing" brand is pretty popular in the multiple-port PC stores.
