My use case is a homelab kubernetes cluster, so I want multiple nodes for redundancy, but I don’t want to use too much electricity or generate too much heat. But for the sake of other readers, let’s keep it general:
What’s a nice little computer for a homelab, with its own power supply, ethernet, and room for 2 internal disks?
Exactly. If you’re running kubernetes, you probably want etcd to have its own disk. And if you don’t have a NAS, then you’re looking at extra disk to hold your data. The data disk should probably be separate from the OS disk.
