Idk, you can probably ask the owner via the shop

The latter, it’s all 3D printed rackmounts

No, not a media server. But it could be with the NAS and just mount a big NAS dataset into one of the servers.

I spent a lot of time automating the setup of the Proxmox nodes with an Ansible role. It install packages, sets up exporters for monitoring, makes some Proxmox tweaks and, most important, creates the file system structures for replication and high availability. The NAS runs TrueNAS which is mostly in the default configuration, similar for the OPNsense firewall.

That’s the operating system site of things. The VMs with the Docker services (Nextcloud, Bookstack, Calibre Web Automated, Authentik, Prometheus Stack with Grafana, this Lemmy instance, Gitea and some more) have just been transfered from the old server.

The Lenovo boxes have single 480GB disks (probably the thing I need to upgrade somewhat soon). Backups go to the NAS which has a 3 x 1,8 TB ZFS mirror (RAID 1 basically) in the JBOD.

This is the first time I’ve heard about using UPS for something other than powering computers in case of a blackout. Shouldn’t the power supplies take care of the rest? Never heard of reducing wear and tear by external components.

Looking for something specific? Lenovos have 4C/8T, 32GB RAM and an extra SSD for the virtual drives. The whole thing is idling just below 50W.

Each box was around 100-150€ plus some drives, 3D material/energy was 15€ and my friend’s bar tab, rails/screws/blinds were around 40€ in total. Bought everything second hand with low price and power consumption in mind.

That sounds like a good opportunity for offsite backup!

Oh cool! Wheels are definitely a good idea. I thought about a UPS but our grid is super stable and apparently they cause their own problems now and then.

They’re all from printables, e.g. https://www.printables.com/model/1040412-lenovo-thinkcentre-tiny-m720qm715qm920q-10-rack-mo

Thanks!

Yeah, couldn’t resist the sticker :D

They are connected to the mini PC below. This mainboard has 4 connectors.

Yeah maybe I’ll try to fit in some faster Ethernet adapters at some point, but currently it’s mostly just the daily VM snapshots and since those are automated, the speed isn’t that important anyways. Just in case of a potential recovery.

Offsite backup at some family member’s place is planned at some point as well, but not fully thought through yet.

No, WAN is the family lan. It’s connected to one of the actual router’s ports (some Fritzbox connected to the ISP). 192.168.1 is inactive, I was just messing around with it when I got the unit.

I’m all on SSDs since I don’t need that much storage, so 2.5 is what I need anyways. There’s a 3x ZFS mirror of 1.8TB SSDs in there, 4th bay is currently empty.

Got them printed by a friend except for the white blinds and the cable brush.

It’s the 2C4. I’m not using it for actual routing but for subnetting and firewall basically and I get a little over 500 Mbit/s through it.

K8S is a whole different approach and I find it to be a lot more complex, but you would not need virtual machines. If all your applications are running in containers anyways, you could consider it. Finding a good solution for persistent storage is probably the most important design decision.

What do you actually need to run on your server? I’d look into downsizing. A single small form factor computer or even a newer Raspi can do a lot these days.
