Managing
power domains in a
data center including establishing a unique
domain identification for each electrical path connecting one or more computing devices to a power source; receiving, by a management module from the computing devices, the unique domain identifications; maintaining, by the management module, a map associating the unique domain identifications with identifications of the computing devices; reporting, by a monitoring module to the management module, status information of a monitored power
service module located in a particular power domain; and identifying by the management module an action to take in dependence upon the status information and the map of the unique domain identifications for the computing device.
