HP Power Advisor

The HP Power Advisor utility reduces the research and guesswork normally involved in determining
power requirements for ProLiant-based systems. Using the HP Power Advisor, an IT administrator can
build a complete system, component-by-component and rack-by-rack, assembling a complete
HP Power Advisor is intended to be a conservative estimator of power. No two
applications will consume exactly the same amount of power. Even programs that
report the same CPU utilization will have different power consumption characteristics,
based on the exact mix and sequence of instructions being executed. The programs
used as the measurement reference for the HP Power Advisor are intended to consume
more power than typical user applications.

Calculator development

HP developed the HP Power Advisor using data collected from testing HP ProLiant servers. Each test
starts with a system fully configured with the maximum number of processors, memory, hard drives,
expansion cards, and power supplies. Proprietary software exercises the processors to the highest
possible power level and operates all peripherals while taking voltage and current measurements.
Testing continues for all levels of processor support at all speeds, with different memory amounts and
hard drive sizes. During development cycles, HP retests revised or updated servers to ensure
calculator integrity.

Calculator functionality

The calculator is a simple drag-and-drop tool. Figure 2 shows the main screen of the HP Power
Advisor. A drop-down menu in the center of the screen lists the choices of AC input voltage to be used
by the server systems.
