HP Virtualization Manager and HP Capacity Advisor: an introduction

Before performing experiments using this scenario, the simulation interval should be set to
reflect the time period to be used for performing the capacity-planning analysis. In this situa-
tion, the interval has been set two years in the future. Using a time interval in the future allows
the workloads’ forecast to be taken into account. This ensures that the workloads will have ad-
equate resources at a future point. Failure to set the simulation interval appropriately could pro-
duce the result that although a workload consolidation appears to fit on the target system, a year
or two in the future the system doesn’t have the capacity to meet the expected growth in the
workloads’ resource requirements.
The next step in this scenario is performing a what-if experiment using the newly defined hy-
pothetical system and the three workloads that have been edited to accurately reflect their his-
toric and future resource requirements.
The screen shown in Figure 18-17 is the What-If Move Workload screen. This interface allows
the selected workloads to be moved to the hypothetical system. This interface does not actually
move the workloads. Instead, it serves as a test-bed for performing capacity-planning scenarios.
