Open Stack

To use the network already there in your datacenter rather than creating a
private network. You can trunk the vlans(you would like to use) on the
switch port and connect it to the compute nodes. then defining the
vlan in openstack by nova network create --vlan id=(vlan id of the vlan on
the switch)

And then they would be publiclly routable without any need for floating ips.

In this way you can horizontally scale up your compute nodes , just by
adding a new port in switch in trunk mode for the vlans you would like.

Hope i am clear.
