    Proxmox cluster - disk layout for ceph

    Hi, I plan to build my first ceph cluster and have some newbie questions. In the beginning I will start with 5 nodes, and plan to reach 50 nodes. Those nodes quite old (CPU E3,16GB RAM, 2x1Gbps network), so I think to gain the performance in adding more nodes but not upgrading RAM or CPU. I...
