HP Virtualization Manager and HP Capacity Advisor: an introduction

System view; thus allowing centralized management and visualization for all of the VSE
technologies.
Beyond the configuration and status of the systems in Virtualization Manager System view, the
resource utilization is also displayed for all the workloads in the VSE management domain. Fur-
thermore, the resource utilization data is aggregated up the hierarchy, which means that utiliza-
tion data is displayed for an entire Superdome that consists of the aggregation of the utilization
for the nPartitions contained in the Superdome. Another example of the data aggregation is that
an nPartition containing multiple virtual partitions will have utilization data shown for each Vir-
tual Partition in addition to the aggregated value for the nPartition. This model provides detailed
utilization metrics from the lowest-level workload up to the highest-level server. The result is a view
of the overall resource utilization for each of the servers in the VSE management domain.
The Virtualization Manager System view also provides seamless integration with a majority
of the VSE configuration tools. Management tools for nPartitions, virtual machines, gWLM
PSETS and FSS groups, and Serviceguard clusters can be invoked from the Virtualization Man-
ager System view by selecting actions from the action menu. The actions for the Virtualization
Manager are available in the menu immediately below the System, Workload, Shared Resource
Domain, and Capacity Advisor tabs. This menu contains actions that are specific to VSE tech-
nologies, whereas the HP SIM menu at the top of the screen contains actions that apply to the
entire HP SIM management domain.
The resource utilization meters shown in the Virtualization Manager System view can also be
clicked, resulting in a display of historical utilization graphs for the selected system or workload.
An example Capacity Advisor historical utilization graph is shown in Figure 17-10. This screen
allows the type of metric to be changed in addition to allowing the interval to be selected. The
historical utilization graphs provide additional context to the real-time utilization values shown
in the System view. In many cases the historical views provide the necessary context to under-
stand whether the real-time utilization value is either too high or too low by comparing the cur-
rent value against the system’s historical utilization patterns.
The second top-level view of the Virtualization Manager is the Workload view. This view pro-
vides a flat list of workloads in the VSE management domain. This view shows the status of the
