I understand, though cephadm isn't that horrible and there are still other ceph
solutions out there. ;)

Yeah but the ratio is 4 DB/WAL to 1 SSD, opposed to 12:1 for an NVMe.
To add, you will need 512 GB RAM for OSDs (60 x 8GB) alone and at least a
32C/64T CPU. Probably some 2x 25 GbE NIC too, depending on the use-case.
Just saying, there are certain expectations with that many disks in one node.

a storage product (yet).
