Ceph networking

Hello,

I have a CEPH cluster with 3 MONs and 6 OSD nodes with 72 OSDs.

I would like to have multiple client and backed networks. I have
now 2x 10Gbps and 2x25Gbps NIC in the nodes and my idea is to
have:

- 2 client network, for example 192.168.1.0/24 on 10Gbps NICs and
192.168.2.0/24 on 25Gbps NICs. One for my clients, one for asynchronous
syncing to another cluster

- 2 backend networks, say 10.0.1.0/24 on 10Gbps NICs and
10.0.2.0/24 on 25Gbps NICs to have multiple backend paths and/or
more throughput.

Is this scenario real? If my clients will be on 192.168.1.0/24
network, will mon give them a addresses of OSD nodes from
192.168.1.0/24 network, or it will give them addresses randomly?

Please, have someone advice, how to set this networking
optimally?

Thanks a lot.

Sincerely
Jan Marek
