Open Stack

For TripleO deployment, you'll need:
A separate node or VM as UnderCloud.
3 control nodes for HA, 2 controllers can't form HA by default, this is to
avoid split-brain scenarios.
For compute nodes, I recommend to have 2 x 10G ports, one for O&M and the
other one for tenants. And a separate 1G for BMC / IPMI.
