Hmm, so this is a bit disappointing, though I may be less disappointed if I knew that Ironic (or something else?) planned to account for datacenter inventory in a more robust way than is currently modeled. If Triple-O/Ironic/Tuskar are indeed meant to be the deployment tooling that an enterprise would use to deploy bare-metal hardware in a continuous fashion, then the modeling of racks, and the attributes of those racks -- location, power supply, etc -- are a critical part of the overall picture. As an example of why something like power supply is important... inside AT&T, we had both 8kW and 16kW power supplies in our datacenters. For a 42U or 44U rack, deployments would be limited to a certain number of compute nodes, based on that power supply. The average power draw for a particular vendor model of compute worker would be used in determining the level of compute node packing that could occur for that rack type within a particular datacenter. This was a fundamental part of datacenter deployment and planning. If the tooling intended to do bare-metal deployment of OpenStack in a continual manner does not plan to account for these kinds of things, then the chances that tooling will be used in enterprise deployments is diminished. And, as we all know, when something isn't used, it withers. That's the last thing I want to happen here. I want all of this to be the bare-metal deployment tooling that is used *by default* in enterprise OpenStack deployments, because the tooling "fits" the expectations of datacenter deployers. It doesn't have to be done tomorrow :) It just needs to be on the map somewhere. I'm not sure if Ironic is the place to put this kind of modeling -- I thought Tuskar was going to be that thing. But really, IMO, it should be on the roadmap somewhere.
