HP-UX WLM provides goal-based workload management. This management enables automatic

resource allocation and application performance management through the use of prioritized

service-level objectives (SLOs). It provides this functionality by automating features of HP Process

Resource Manager (PRM), HP-UX Virtual Partitions, nPartitions, and processor sets.

HP-UX WLM offers the following features:

• Automatic allocation of CPU resources (cores) to your most critical applications (allocation

of time slices on cores as well as whole cores when managing processor sets, virtual partitions,

or nPartitions)

A core is the actual data-processing engine within a processor, where a single processor

might have multiple cores, and a core might support multiple execution threads; for more

information, see the WLM HP-UX Workload Manager User’s Guide.

• User-configured allocation of real memory and disk bandwidth resources

• Shares-based and goal-based SLOs

• CPU shares-per-metric allocations, which allow you to give a workload, for example, 2% of

the CPU resources for each process in the workload

• Multiple SLOs at different priorities, allowing you to have a “must meet” goal and optional

stretch goals for each workload

• Passive mode for analyzing a configuration’s behavior

• Audit and billing data

• Ability to set minimum and maximum amounts of cores available to a workload

• Time-based and metric-based activation of SLOs, including the ability to activate SLOs

associated with a Serviceguard package on failover

• GUI for creating, modifying, and deploying WLM configurations locally and on remote

systems

• Integration with HP Systems Insight Manager, allowing you to remotely control WLM

running on numerous nodes from a single point of administration
