HP Virtualization Manager and HP Capacity Advisor: an introduction

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 the month
of January. The scale of the y-axis is based on CPU shares, with 100 shares equaling one physi-
cal CPU. This workload consumed roughly seven CPUs at its highest peaks.
The graph shown in Figure 18-2 is the CPU utilization for a second workload HP’s internal
IT department examined. As with the previous graph, the y-axis of the graph is based on CPU
shares. This workload consumed almost eight CPUs at its highest peak. When the two graphs are
examined together, it appears the utilization patterns of the workloads are closely aligned and
experience peaks at roughly the same time. However, as shown in the next graph, that is not nec-
essarily the case.
