Nonsense. We  use whiteboxes, desktop HDD, no RAID cards, etc. with 
Ceph/Proxmox and works really well. Effort to maintain it is... near 
zero. Effort to deploy just 15 minutes, thanks to Proxmox integration.

> Can Ceph run multiple replication and ec levels for different files on the same volume? Can you change goal settings on the fly? Near instantaneous spanshots and restores at any level of the filesystem you choose? Run on commodity hardware with trivial adding of disks as required?
You don't do files on Ceph, you just do volumes (vdisks). Ceph is not a 
filesystem (although has a filesystem - CephFS). We use commodity 
hardware and add disks trivially.

I don't say Ceph may be for every use cases; but don't talk lightly 
about something you don't know.

Cheers
