Cluster and CEPH traffic on the same network

Hi!

I'm implementing 3-node Proxmox cluster with CEPH storage.
Each node has 4Gbit LACP interface (made of 4*1Gbit physical) as a public, and two 10Gbit interfaces for CEPH traffic.
Is it a good idea to have Cluster and CEPH traffic both on 10Gbit interface?
Or should I use public interface for cluster and VM traffic and leave 10Gbit only for CEPH?

Right now I've already make it combined, and it seems to work fine with standard MTU 1500, but when I start playing with MTU 9000, cluster nodes stop seeing each other.

Thanks for help, Alex
 
ok, Proxmox documentation recommends to separate cluster trafic from storage because cluster traffic depends on latency heavily.
So I decided to remove 1 physical interface from LACP aggregated link and dedicate it for cluster trafic only.
