Description of problem:
OSP includes very basic NIC config examples for just a few configurations. None of the included configurations are appropriate examples for a production Ceph deployment.
Version-Release number of selected component (if applicable):
OSP 13 and previous versions
The included sample NIC configs are not optimized for Ceph. Only the multiple-nics version of the templates have storage interfaces that are not on a bridge. Bridges are not required for most use cases when using Ceph, and by not using bridges there is more CPU available for Ceph.
At least one example (perhaps more than one) should illustrate a production Ceph use case.
We should also document that bridges are not usually required for Ceph (except when using OVS bonds, which are less common than Linux bonds).
