Capacity– Ultimate limitation– Usually influenced by outside factors
Design Point– Redundancy (n+1, 2n)– Availability
Operating Point– Reliability– Additional safety margin
Capacity – 1600 kW (2 x 800 kW UPSs)
Design Point – 800 kW (2n)
Operating Point – 600 kW (each UPS has 4 x 200 kW modules)

Air conditioning capacity based on actual power consumption
Air conditioning capacity based on max power consumption
Planning based on maximum measured power consumption results in a reduction of sensible cooling capacity (19 kW) and the operation of three additional Cooling Room Air Conditioning (CRAC) units.

IBM SEE Overview
IBM Systems Energy Estimator– Standalone web application
“The IBM Systems Energy Estimator is a web-based tool for estimating power requirements for IBM Power Systems. You can use this tool to estimate typical power requirements (watts) for a specific system configuration under normal operating conditions.”
– Deployed initial offering October 2008, latest update was August 18, 2009
– Supports Power Systems (POWER6 and newer)Follow-on to Power Load Calculator (POWER5)
– Averages 400 energy estimations per weekUser feedback has been positive, affirms that energy requirements are an increasingly
important component of purchase decision
– Represents significant collaboration between STG Development, Systems Assurance, WW Tech Support Tools, and Systems Performance

*The calculated energy estimate is an expected, typical value for this system
configuration under normal environmental operating conditions. It should not be used
in planning the electrical supply infrastructure.
