HP-UX Workload Manager (WLM) A.03.05 runs under the following HP-UX operating systems
and hardware:
HardwareOperating Systems
HP 9000 servers, HP Integrity servers, and servers combining
HP 9000 partitions and HP Integrity partitions
HP-UX 11i v3 (B.11.31)
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
