HP-UX Workload Manager User's Guide

Introduction
Performance and resource management overview
Chapter 138
The remainder of this document focuses on the last two rows of Table 1-2:
Automatically managing multiple, prioritized workloads on a single
server—possibly across partitions—based on reported performance
levels or usage goals. This strategy is commonly referred to as goal-based
workload management.
WLM implements this type of workload management allowing you to:
• Optimize your return on investment in servers
• Maintain multiple applications on a single server without increasing
performance problems
• Improve your ability to forecast capacity needs
Multiple workloads:
Variable resource
allocations based on CPU
utilization per workload
Example: HP-UX WLM
• Optimal resource
utilization is maintained
automatically
• Workloads can be
prioritized to ensure
that high-priority
workloads are
guaranteed CPU
resources as needed
• Excess resources can
easily be tracked with
PRM and GlancePlus
tools enabling reserve
capacity to be deployed
to save costs and
guaranteesing
high-priority workloads
the available resources,
as needed
• CPU resource
allocations are not made
based on
application-specific
metrics
