We upgraded the proxmox to 7. with latest ceph. and almost everything back to normal..

Currently our main network is the same network with the corosync and consists of 11 nodes, (4 of them with ceph)

We plan to double the server count in the near future and i thinking of moving the corosync to a dedicated network, because off high load on the network.
This will including dedicated switch. (i think to keep both rings for redundancy in case of switch failure )
all servers have unsued nic port that will be used for this task.

also thinking adding an NTP to this network at later stage to

what is the best practice to do it? because our cluster is the core of our company infrastructure. (we have backups pbs and cold backups) but i would like to avoid a crisis
