    Storage configuration setup : Nvme+HDD vs. Nvme

    Hypervisor with 1 disk is nonsense if you don't have multiple such hypervisors with network storage. Solution: 2x ssd raid (pve+vm/cs) + hdd raid as data/backup storage only or 2x ssd raid (pve) + 2x ssd raid (vm/ct) etc.

    New all flash Proxmox Ceph Installation

    Drop 10Gbps rj45 and use sfp+ only (10,25Gbps variant, dac or fibre). Power consumption and latency are better. You can use extra 2x nvme disks per node as other data pool.

    Cluster communication is based on ssh, so fix ssh (key, authorized_keys) on every node (/etc/root, /etc/pve directories).
