[PVE-User] Shared storage recommendations

[Gilberto Nunes]

Hi

IMHO, ceph are very good.
I have a production environment, using 6 servers in Proxmox CEPH Cluster.
No data loss so far. Performance is good. Unfortunately the hardware which
I have at hand are low in memory ram... But still, OK for most of the job,
