Been planning to migrate from my Supermicro monolith server for a while and finally finished the migration. Red thing is opnsense on an APU engine, Lenovos run a proxmox cluster, below is a mini PC with attached JBOD running TrueNAS.
Next step is to get another shelf for my Raspi and openDTU.
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.
How much storage do you have? Are you using raid?
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.
Hm so this isn’t a media server? 480 wouldn’t seem like enough?
How much work was the software side to get this up and running? Are there libraries to make it easy or did you have to configure everything yourself?
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.
