Ceph and Main Network Considerations

I understand that it is best practice to have Ceph running on a separate network to the main proxmox network. I have two network setups, one considerably faster than the other (40gbit & 10gbit). Is it better to have the faster for Ceph, or for the main proxmox network?

* I would use the 40g for ceph (all disk-access of your guests will go over this network (multiple times) ).
* the PVE-network will be used for corosync (which needs a low latency, but not much bandwidth) and migrations (the guests' state (ram)) - which is usually less demanding on the bandwidth side

hope this helps!
