That is rather a generic question.
For example you can find a MangementController which is managing blades. The blades can be individual Hosts with a HostContainer bringing them together in a single container. There recognising the ManagementController drove the model. The mapping then goes from a Host to the HostContainer (a BMC_ComputerSystem representing the blade system) and then to the ManagementController (BMC_HardwareSystemComponent).
