Until something goes wrong in your stack, and then you're despairing.
That's why I run a cluster and tight backups. I can recover
I want to upgrade to 3 MS-A2 but they are much more expensive (about $1350 per box) but a lot more powerful 2.5x the passmark score, 96GB DDR5 vs 32GB DDR4, and would have raid 1 NVME 2TB instead of a single 2TB nvme. It would also allow me to connect them directly to my 10Gbit SFP+ backbone. The power draw a lot higher though.
