Is it "takes an entire Raspberry Pi to run the minimum set" or is it "takes 4 cores per OSD"? Edit: This is the specific doc page https://canonical-microceph.readthedocs-hosted.com/stable/ho...

Ceph has multiple daemons that would need to be running: monitor, manager, OSD (1 per storage device), and RADOS Gateway (RGW). If you only had a single storage device it would still be 4 daemons.
