Figure 2 Understanding Power Delivery Hierarchy
• Power Feed: A top-level input of power from the data center facility into the power
management-observable power infrastructure.
• Breaker Panel: This represents the total group of breakers on a single Breaker Panel in a PDR.
• Branch Circuit: This represents a single output of a PDR circuit breaker or power meter.
• Rack PDU: Rack Power Distribution Unit - This represents the input power and multiple outputs
to load segments.
• Load Segment: This represents each of the outputs of the PDU that can be monitored. HP PDU
Management Module discovers up to the Load Segment level of the power topology.
• Outlet Bar: This represents the division of the load segment into multiple outlets.
• Outlet: A circuit with one input and one output that can be monitored.
• Load: The power consumer connected to the outlet. The load can be a system, enclosure, or
undiscoverable system.
Power Calculation
Assumptions
Insight Control power management assumes the following for calculating power:
• 1-phase is treated as 1-phase NA/JPN (line-to-line). You cannot change this to INT 1-phase.
• The load factor is 1. So, VA and Watts units are the same.
• All loads are balanced.
Power calculation
The power calculation in general can be categorized as:
• Power delivery device voltage discovery
• Power delivery device total capacity calculations
• Converting watts to amperes
• Converting amperes to watts
Power delivery device voltage discovery
If you know the power hierarchy of a power delivery device, the missing voltages can be found
during discovery phase. Insight Control power management finds the missing voltages for 1-phase,
