I’ve been running VMs on some old DELL T110ii but realise that I’ve loaded it a bit too much so want to leave it doing the job of NAS with Truenas Scale and move all my VMs to Proxmox. The idea is that I would have two optiplex that provide redundancy. Truenas Scale has got me used to ZFS but clear may not be an option with Optiplex 3020 as ZFS is pointless with one SSD. Has anyone got some similar arrangement and has their VMs and containers running on these simple desktop machines? How are you managing high availability and resilience?
What’s high availability to you? There’s an increasing cost.
Anyway, I have a similar setup. NAS for storage and OptiPlex Proxmox nodes for compute. But I went a different route and set up an iSCSI SAN and all the guests use block storage on the NAS. Guest backups by Proxmox go to file storage on the NAS and backed up to a second NAS.
