Recommended hardware
Take a look at our Proxmox VE Ceph Benchmark 2018/02 for possible hardware decisions. https://www.proxmox.com/en/downloads/item/proxmox-ve-ceph-benchmark
Further readings about Ceph
Ceph comes with plenty of documentation here. Even better, the dissertation from the creator of Ceph - Sage A. Weil - is also available. By reading that thesis you can get an in-depth insight how Ceph works.

restore lxc from zfs to ceph
if lxc is on zfs with compression the actual disk usage can be far greater then expected. see https://forum.proxmox.com/threads/lxc-restore-fail-to-ceph.32419/#post-161287
One way to know actual disk usage:
- restore backup to a ext4 directory and run du -sh , then do restore manually specifying target disk size.
scsi setting
make sure that you use virtio-scsi controller (not LSI), see VM options. I remember some panic when using LSI recently but I did not debug it further as modern OS should use virtio-scsi anyways. https://forum.proxmox.com/threads/restarted-a-node-some-kvms-on-other-nodes-panic.32806
