Wire speed L2 in hardware is cheap, but layer 3 is not (and is typically limited to few k routes for campus type of switches). I have a Quanta LB 10G and a Brocade ICX 1G/10G/40G switches for lab use, which are hot and screamy but were cheap used. I would not trust software L3 implementations to not drop packets at high rates.

That’s pretty good. Which models are these?

Interesting. Wonder how much horsepower they have in the L3 department.

I joined over 18 years ago. I agree Lemmy and Fediverse has a future, however online engagement has been falling for many years. I don’t expect it to reverse, since most people will be dealing with rising problems in their personal life.

I’ve stopped using reddit the moment they locked out third party apps. I still read one community in read-only mode. I’ll stop doing that when they’ll kill off old.reddit.com.

Neither 10G multiport routers nor L3 wirespeed switches are low power. We’re looking at 100+ W to multiple hundred watts. In 1U these are rather screamy.

The product you linked is a cheap fanless 10G layer 2 switch. It’s ok for the price, as fanless 10G enterprise switches are hard to get used.

There are suitable 10G capable Mikrotik routers however. This one, for instance: https://www.amazon.de/MikroTik-RB5009UPr-S-IN/dp/B0BBW159WW If you want wirespeed 10G routing on two or more ports it’s going to get expensive and/or noisy fast. A good compromise is a single 10G port router in a router on a stick mode used with a cheap 10G layer 2 switch.

You need at least one 10G port which is a pain on the Lenovo. There is a 10G passively cooled Mikrotik with sufficient power available.

https://wiki.debian.org/ZFS has nice docs. I would practice in nonproduction first if you’re unfamiliar with zfs.

No hardware RAID. Use zfs, if you can. Mirror the boot SSD. I would use a stripe over mirror and 4 HDDs. Two drives are not enough redundancy. Use enterprise or nearline drives, if you can. Debian is great, you can install Proxmox on top of it, but from the sound of it plain Debian would work for you.

NATO/Russia 3rd world war, still reasonably limited to just two countries, for time being.
