3.4.25 PUE/DCiE/Summary/Average
PUE and DCiE calculations are valuable metrics used by data centers to track their energy efficiency. PUE measures the efficiency of the
computing equipment, while DCiE measures the efficiency of the data center’s infrastructure. Maximizing the energy efficiency of
computing equipment and the data center infrastructure helps reduce energy costs and can minimize data center down time.
The RIM-1000 provides a set of tools that help track real-time PUE and DCiE information, as well as logging long-term PUE/DCiE trending
information. A chart with PUE/DCiE information can be found on the lower right side of the RIM-1000 home page.
Figure 3.42 PUE/DCiE Data on RIM-1000 Home Page
Before you can generate PUE/DCiE data through the RIM-1000, you need some data for the RIM-1000 to work with. Submeters
need to be wired, or SNMP/Modbus communications need to be established to gather the following kilowatt (kW) readings:
• Utility load - The main power feed into the building - usually obtained through a submeter.
• IT load - Power consumed by all computing devices - usually obtained through a submeter or through protocol SNMP/Modbus
communications.
• Ancillary load (optional) - The portions of the building outside the data center, including warehouse space, offices, etc. - usually
obtained through a submeter or through protocol SNMP/Modbus communications.
