Power Topology Profile
Version 1.0.0a 13
6.1.2 External Power Domains
A managed system, depending on the power infrastructure architecture that it is plugged in to, may have
a need to model external power sources as external power domains. The power supplies of the managed
system can draw power from a specific external power domain. This functionality is modeled by an
instance of the CIM_AdminDomain class representing an external power domain that is associated to the
instances of CIM_PowerSupply, representing power supplies drawing the power from the external power
domain by the CIM_SystemComponent association.
6.2 Power Source Redundancy
Power source redundancy is defined as the redundancy of power in respect to the consumers of the
power sources, and the availability of the power to the consumers if one of the power sources in the
power source redundancy malfunctions. There are two levels of such power source redundancy: internal
represented by power supply redundancy and external represented by external power domain
redundancy.
6.2.1 Power Supply Redundancy
The redundancy of power supplies in a managed system is in respect to the redundancy of the power
consumed by managed elements that are supplied by the power supplies constituting the internal power
redundancy. The requirements for power supply redundancy are described in DSP1015. This profile
describes requirements in addition to the ones specified in DSP1015.
6.2.2 External Power Domain Redundancy
The redundancy of external domains in a managed system is in respect to the redundancy of power
consumed by managed elements that originate from the external power sources.
The redundancy of external domains is represented through an instance of CIM_RedudnacySet. Each of
the instances of the CIM_AdminDomain instance that corresponds to the external redundant power
source is associated to the instance of CIM_RedundancySet through an instance of
CIM_MemberOfCollection.
6.3 Power Management Service
The power management service represented by the Dell_OEMPowerConfigurationService class provides
the capability for configuring external redundancy, maintaining desired redundancy, and manipulating the
requested actions for power overconsumption by the managed system. The capabilities of the service
represented by the Dell_OEMPowerConfigurationCapabilities class advertise the supported methods and
redundancy levels.
7 Implementation Requirements
Requirements and guidelines for propagating and formulating certain properties of the classes are
discussed in this section. Methods are listed in section 8 and properties are listed in section 10.
7.1 Internal Power Domains (Optional)
A system may be responsible for providing power to the components installed in it. When a system
supplies power to components, there may be one or more internal power domains of which the
components are members. The internal power domains of the system should be modeled. When the
internal power domains of a system are modeled, the requirements detailed in the following sub-clauses
shall be met.
