Hello Christian,
                          That recommendation is for the hyper-converged installation as the nodes are also the storage servers so you would choose the storage addresses when setting up the gluster network.
The other thing is you may have to setup a display network proxy if your clients can't reach nodes.


Regards,
                Paul S.

Subject: [ovirt-users] Quick question regarding FQDN
 
Hey folks,

for production use quality it is recommended to have backend (storage)
and front end seperated. Let' assume:

  - 85.0.0.0/24 public IP block
  - 10.100.0.0/24 private IPs for DC internal usage
  - 10.200.0.0/24 private IPs for storage only LAN

and running, as per recommendation 3 nodes:

  - node01:
    - fqdn: node01.dc-example.com
    - fqdn storage: node02.storage.example.com
    - no public IP
    - 10.100.0.1 primary IP
    - 10.200.0.1 storage IP

  - node02:
    - fqdn: node02.dc-example.com
    - fqdn storage: node02.storage.example.com
    - no public IP
    - 10.100.0.2 primary IP
    - 10.200.0.2 storage IP

  - node03:
    - fqdn: node03.dc-example.com
    - fqdn storage: node02.storage.example.com
    - no public IP
    - 10.100.0.3 primary IP
    - 10.200.0.3 storage IP

The storage network is its own physical network with 10gig that only
connects those three servers. How can I specify which IP to use for
storage, which for frontend traffic?

I am assuming this as the controller and all admins should be able to
reach the nodes via frontend, which is not the storage one.

Okay, I am lost. Whats the real solution here?
Or is "frontend" no-ip, just VM traffic and "backend" is the 10gig
storage "Only" where all the FQDN reside?

Thanks for clarification,
-Chris.
