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

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!
