6.1 Power Domains
There are two types of power domains modeled within the managed system: internal power domains and
external power domains. Internal power domains correspond to internal power grids, where the power
domain is supplied power by one or many power supplies. External power domains correspond to the
external power sources, where one or many power supplies draw their power from different power
domains.
The power domains are only relevant in the scope of the managed system, and may not have one to one
correspondence with the power domains that exist in the scope of a datacenter. The instance of
CIM_AdminDomain representing the external power domains shall be associated to the scoping instance
using CIM_OwningCollectionElement association.
6.1.1 Internal Power Domains
A managed system, depending on the architecture, might have numerous internal power domains. The
components of the managed system can draw power from a specific internal power domain and each of
the internal power domains are supplied power by designated power supplies. This functionality is
modeled by an instance of the CIM_AdminDomain class representing an internal power domain that is
associated to the components drawing the power from the domain by CIM_SystemComponent
association, and to the power supplies supplying power to the domain by the CIM_SuppliesPower
association.
