Re: Ceph OSD network configuration

Hi,

you can/need to configure the clusternetwork and the publicnetwork.

In the ceph.conf that means:

public_network = 1.2.3.0/24
cluster_network = 2.3.4.0/24

as an example.

So you will, for every node in your ceph cluster, use

1x 10G Port for public network ip
1x 10G Port for cluster network ip

----

The cluster network is for internal syncronisation between the cluster
nodes.

The public network is for the delivery of the data to where ever you
want to mount/use the data ( the clients of the storage cluster ).

So you dont need any bonding. And also you need BOTH networks up and
running to make it work.

In general, the clusternetwork and the public network can also come from
the same logical network, but thats not recommanded.

The way is usually to build independent vlans and have them on
independent NIC ports to ensure performance.

But technically you can also run everything over 1 NIC port.
