Windows, specifically is where I had the problem. That machine never got Linux, so I hadn't tested it there.
If it does work fine with presumably non-bleeding-edge livecd kernel, chances are it will be as good or better with newer kernel. my personal experience is i could go beyond specified supported max resolution on 2nd-3rd gen intel core builtin gpus, but with slower refresh rates that is. which technically should be totally fine and expected. you're still rendering same supported amount of pixels per second. you set higher resultion but at slower speeds. i cannot test it with 4k displays because i dont have one, but logic tells me this should totally work. ymmv but tias if you can?I know , but will I get the "real" graphic experience this way? Will the live mode use the same graphic drivers as a normal installation?
I will test it next week at the office. Maybe I will prepare the Ubuntu live USB and some other distro.If it does work fine with presumably non-bleeding-edge livecd kernel, chances are it will be as good or better with newer kernel. my personal experience is i could go beyond specified supported max resolution on 2nd-3rd gen intel core builtin gpus, but with slower refresh rates that is. which technically should be totally fine and expected. you're still rendering same supported amount of pixels per second. you set higher resultion but at slower speeds. i cannot test it with 4k displays because i dont have one, but logic tells me this should totally work. ymmv but tias if you can?
Since you had a decent amount of RAM, you may want to start the live USB of the newest version (21.10 for Ubuntu) and run the software updater to update to the latest version packages. You can do that without writing to disk. It takes up RAM to do this, but with 16GB it would probably be OK if there aren't a ton of updates. 20.04.3 is the newest Long Term Support (LTS) version, but I'm not sure how many updates there are for that if you try to run updater live.I will test it next week at the office. Maybe I will prepare the Ubuntu live USB and some other distro.
thank you both for your reply! I think 1L is perfect, 2L would fit as well - so one or the other.as a guy who owns P340 tiny and a couple of passive cooled low-end lenovo units:
1L is 1L, its not that big.
Personal experience p340 tiny is quiet in idle.
-cant tell anything on how much they use, you should check out patrick's reviews on STH for that
cpus are upgradable for most but not recent ryzen units (M75q Tiny Gen2) if you buy new then maybe consider buying low-end then buy one you want and swap. most lenovo units easily support 2x32(64GB) so no troubles running 8GBx2 or 16GBx2.
what issues with proxmox and where? i'm interested. these units are almost like little servers and their hardware is supposed to be supported by all modern linuxes, you can check out compatibility/certification of ubuntu for example to make a decision.
lenovo: no native 2.5G LAN, i'd recommend using 2.5G USB NIC or "5G" USB NIC. "5G" because it's superspeed and superspeed is 5Gbit. Add the usb protocol overhead and you end up with something like 4. Patrick did a video on that a long time ago. optionally i350 in pcie slot for 4x1G ports.
hwraid via PCIE card if you want to but where are you gonna put the drives is the question.
haven't heard of ECC in these 1L units from lenovo specifically. P340 due to its non-xeon chipset won't power up with xeon and ecc ram.
my thoughts: minisforum are bga onboard-everything, with no path for upgrade or component replacement. and they're costly thingies. and then i had some laugh on gamersnexus videomaybe you'd enjoy that too. make sure to grab some popcorn.
ok, so then the options get a lot better. And there is no problem with proxmox routing the traffic directly to a USB-nic? Do have experience with this?i use a lot of usb nics and so far they didn't fail or flap. just doesn't happen. but i only use 1g, mostly tp-link(again, rtl chip based), ymmv but as it's a normal usb device it should be as reliable as any other usb device, granted it's a well-known brand like tp-link.
if interested, tp-link UE300 is the most commonly used usb nic in my network. on older kernels they seem to be having issue with not sensing packets which i used to solve by enabling promisc mode on the interface and that solved it but don't remember doing that on a newer installations anymore. also might have been a single faulty unit. at a price of around 10 bucks new it's a good deal to me for 1g nic. if you need reliability do some form of soft-failover that would let you hotswap a faulty unit.
No issues, you connect it to the box and the base Proxmox Debian-based OS detects it and sets it up there. Then all your VMs are virtualised above that and talk to the USB NIC through the Proxmox abstraction layer (ie KVM). USB NICs will even work under ESXi although you do need the USB NIC Fling (link is in the Lenovo Tiny Reference thread advertised earlier). You can even install a 2x 10GbE PCIe (or presumably 1x 10 GbE) card in the Lenovo Tinys, check the reference thread for info on that as well.ok, so then the options get a lot better. And there is no problem with proxmox routing the traffic directly to a USB-nic? Do have experience with this?
If you want to run this all on one physical server then yes, you will need something like Proxmox to at least have two VMs, one for pfSense/OpnSense/Sophos and one for the applications you want to run. On the application server you would run your favourite flavour of Linux and Docker.I want to use the system with proxmox 24/7 to control smart home (mainly lights) and get some advanced network security. So I thought about some lxc containers (dont know if I need a VM at all) with
- Maybe some tools for video surveillance and a little playground
In this setup technically the "LAN" connection from the firewall VM to the applications VM could be over a bridge within Proxmox, and then you only potentially need one LAN port. However I would actually recommend having two NICs since you presumably have other devices on your LAN.
- 2x RJ45 (ideally in 2,5G) would be great because I would be able to separate internet from LAN
Most of us here are buying these small units second hand, not new. So then the cost of even a performant model using one or two gen old tech (Core Gen 8/9, or a Ryzen 3400GE) with 16GB RAM and NVMe is more like £250/$300, which makes it much cheaper than what you're suggesting. You could buy two complete physical systems for what you're proposing to spend. This also would avoid the issue of a Proxmox update or issue bringing down both your firewall and your application server at the same time, your whole home network getting upset because you no longer have a default gateway while the server is rebooting, etc. The Lenovo Tiny Reference (sorry to keep advertising it) lists many of the CPUs and their Passmarks so you can get a feel for what you need in terms of compute performance. With my boxes I run out of RAM way before I run out of CPU.My thoughts:
- I am not sure if I should go with Intel or AMD, but the Lenovo M75q Gen 2 sounds nice. Problem is, that I would only get 1x RJ45 and I didnt find an extension for the punch-out hole that would get me a second. I would be able to buy a campus version of it (5650GE, 16GB RAM, 512 NVMe) for about 600$ (in Germany, so it is not compareable to your prices, but compared to other new units the price/performance is fine)
- Then I read about the minisforum line on servethehome and thought about a HX90, but the CPU is a bit oversized, it is big (even though 2L case would fit as well) and might be louder than the Lenovo. And it costs around 680$ as a barebone with not significantly more advantages for my use case
- The minisforum TL50 would give me 2x 2,5Gb ports with a slightly outdated CPU, but nevertheless more than I need. At around 570$ with 16GB installed, it almost compares to the Lenovo. TH50 on presale seems to be the minor update
I didnt do intensive research, but the 10-15 typical used resellers were as well pricy for second hand hardware on the german market. There are a lot of Intel Core i5-8500 from Fujitsu for around 450€ - with 16GB RAM and 256 ssd. In comparison to this, I would highly recommend the new M75q 2 for 520€...Can't agree more on the costs. Unless you need warranty i dont see any reason buying these new. A valid point may be these can be smelly second hand, say coming from smoking environment or like my ip phone, still smells with some perfume years since i bought it second hand lol.
