you review all the `available options <https://git.openstack.org/cgit/openstack/ironic/tree/etc/ironic/ironic.conf.sample>`_

It is possible to set up an ironic-api and an ironic-conductor services on the
|
||||
same host or different hosts. Users also can add new ironic-conductor hosts
|
||||
to deal with an increasing number of bare metal nodes. But the additional ironic-conductor
|

services should be at the same version as that of existing ironic-conductor services.
