A Reason for Capacity Planning

Before diving in to the Capacity Advisor example scenario, one of the many reasons for capacity planning is illustrated using an experiment that was performed using data from production workloads in HP's internal IT department. In this experiment, the data for two production workloads was collected. The data was then used to determine whether consolidating the two workloads would result in reduced hardware requirements. Of course, reducing the number of required CPUs results in a reduction in both hardware costs and software licensing costs.

The graph shown in Figure 18-1 depicts the resource utilization for the first workload to be examined in HP's internal IT department. The graph shows the CPU utilization for ...
