Hi Martin,
Thanks for your response. You mean one network interface for only MON hosts or for the
whole cluster including OSD hosts? I’m confusing now because there are some projects that
only use one public network for the whole cluster. That means the rebalancing, replicating
objects and heartbeats from OSD hosts would affects the performance of Ceph client.

Hello Nghia,
just use one network interface card and use frontend and backend traffic on the same. No
problem with that.
If you have a dual port card, use both ports as an LACP channel and maybe separate it
using VLANs if you want to, but not required as well.

Hi everyone,
I have a question about the network setup. From the document, It’s recommended to have 2
NICs per hosts as described in below picture
[Diagram]
In the picture, OSD hosts will connect to the Cluster network for replicate and heartbeat
between OSDs, therefore, we definitely need 2 NICs for it. But seems there are no
connections between Ceph MON and Cluster network. Can we install 1 NIC on Ceph MON then?
I appreciated any comments!
Thank you!
