HP Capacity Advisor 7.2 User Guide

• On the System tab, click a Calibrate Power link in the “Power Utilization” column on the Edit
Scenario system list table (This link appears when CPU information is available, but power
has not yet been calibrated.)
• Also on the System tab, you can select the check box to the left of the desired system, and
select Edit→Calibrate Power (All Selected Systems) on the Capacity Advisor menu bar.
• From the profile viewer for a specific system, click the Calibrate Power link.
Procedure 44 Selecting a calibration option for a single system
1. Review the current configuration shown in the summary area.
2. Click the radio button to the left of the desired calibration option.
3. Supply values for idle and maximum power usage when manual calibration is selected. (See
“Power calibration calculations” (page 189) for assistance in determining valid values for
particular systems.)
4. Select Apply or OK .
Calibrating multiple systems at once
On the System tab, select the check boxes to the left of the desired systems, and select
Edit→Calibrate Power (All Selected Systems) on the Planning tab menu bar.
Procedure 45 Selecting a calibration option for multiple systems
1. Click the radio button to the left of the desired calibration option.
2. Supply values for idle and maximum power usage when manual calibration is selected. (See
for assistance in determining valid values for particular systems.)
Procedure 46 Confirming system selection
1. Review the list of systems in the Selected Systems table.
2. Optional: Click the remove link to delete a system from the table and remove it from the
calibration operation.
3. Select Apply or OK to set the new calibration value for all systems remaining in the table .
Calibrate a single system at a time:
For each system in the Selected Systems table that you want to calibrate individually, click the
details link to open the Calibrate Power (Single System) screen for that system.
TIP: If you elect to individually calibrate some of the systems in a multiple listing, but not all, first
calibrate the individual systems, and then remove them from the Selected Systems table. The systems
remaining in the table list are those to which you can apply a different set of values at once using
the control buttons on this screen.

• Estimating potential power savings across a range of servers (page 149)
Automating time-consuming simulations
The Smart Solver calculates where to place workloads among the pool of available servers to
reduce the number of servers used or to balance workloads across the servers. The Smart Solver
technology uses workload traces to quantify the demands placed by the workloads on the servers
and uses the workload traces to calculate viable placement solutions subject to user-defined
constraints, such as workload utilization limits and the specific resources that may be used.
IMPORTANT: For specific descriptions of each field or summary table on the user interface
screens, click the help topic link on the software screen for the task.
