Anyone here running HA clusters on low power or at least non-enterprise hardware? I am debating getting 2-3 sff computers or something and getting a proxmox clust going. Was just curious what people are actually doing in the wild.
I am currently making plans to move away from my storage cluster. BeeGFS is fun and games, but at home, oh boy!
Will consolidate various SBCs each with their own drive down to just one box (I think the enterprise marketing term is “hyperconverged infrastructure” 
).
What are you doing where you need the uptime of 3-way redundancy?

I have containerized everything except my firewall (pfsesnse VM) and my NAS (TruNAS Scale baremetal acting as hypervisor). I am increasingly unhappy with SCALE as a hypervisor and am going to go back to proxmox or Debian one way or another. Was exploring the idea of some sort of HA cluster or failover setup. Mainly what I am concerned about is my Home Assistant, DNS, and Nextcloud.
If Raspberry Pi’s are coming back into stock I am not opposed to having them work as backups.

It’s better than it was with the rPis, but they might still be hard to find at reasonable prices.
Yeah I’m not gonna pay $140 for a scapled top end RPi.
Id rather buy one of those small 1L SFF units from STH and slap them on a rack shelf.
Odroid has been serving me well.
BananaPi, has cool features, has been a bit hit or miss for me.
Just to clarify, even though there isn’t a standard, the industry usually refers to SFF as the half height units that use desktop parts and are still quite large.
“Minis” are the super small units that use laptop hardware.
Not sure where OP is and I’m sure shipping would be prohibitive, but I have three HP ProDesks with i7-8700s for $500 that someone put a deposit on more than 90 days ago.
Currently using 3 Intel Nuc’s and Proxmox to do precisely this, with everything but firewall, NAS, and Game Servers handled within the cluster. Has been really good so far, might be worth a look for your needs. Certainly not as cheap as a stack of Pi’s, but you get the comfort of longer term reliability with a still quite low power budget, and potentially a lot more compute depending on the NUC model.
