Network IO and Disk IO), all of which are updated in real time. Clicking the CPU bar shows a graph

Automated Workload Management
After determining that the server is experiencing performance problems by reviewing the information
in HP SIM and the VSE Virtualization Manager view, the administrator decides to confirm that the
nPartition is receiving the CPU shares allocated to it. The gWLM component provides the means to
specify and automate CPU allocation to workloads. The workloads can be virtual partitions, virtual
machines or applications running on an operating system instance. The administrator can set gWLM
policies that control the automated allocation based on priority, in combination with minimum,
maximum and guaranteed share of CPU settings for workloads. Controlling resource allocation
based on policies has many benefits: workload behavior and performance become more predictable,
workloads can more safely be grouped on common servers, and underutilized CPUs can be shifted to
busy workloads that can use them.
Figure 3 shows the graphical user interface of gWLM, which is integrated into both Virtualization
Manager and HP SIM. From this common interface, the administrator can configure the gWLM
resource allocation properties of all the servers and workloads in the VSE environment. To avoid
irrelevant alerts, do not use SA audit policies that monitor the number of CPUs configured for a
partitioned server when configuring gWLM automatic resource allocation policies for servers.
