thanks for the replies, I don't know that cephFS clients go through the MONs, they reach the OSDs directly. When I mentioned NFS, I meant NFS clients (ie. not cephFS clients) This should have been pretty straight forward.Anyone doing HA on the MONs? How do you mount the cephFS shares, surely you'd have a vip?
When you mount cephfs or an RBD (for your NFS case) you provide a list of monitors. They are, by nature, highly available. They do not rely in any sort of VIP failover like keepalived or pacemaker.

Client traffic only goes over the public network. Only OSD to OSD traffic (replication, rebalancing, recovery go over the cluster network)

Separating the network is a plus for troubleshooting and sizing for bandwidth

Don’t really understand the question (NFS vs CephFS).
