HP-UX Workload Manager User's Guide

Configuring WLM
Defining SLOs
Chapter 5196
NOTE If you plan on managing only virtual partitions or nPartitions—with no
FSS groups or PSETs inside, the entity keyword is not needed.
Specify the workload group to which an SLO applies using the entity
keyword. The entity keyword is required. Use the following syntax:
entity = PRM group group_name;
where
group_name Is a workload group name.
NOTE You cannot specify PRM_SYS in an slo structure.
Specifying the lower and upper bound requests on
CPU resources (optional)
Specify lower and upper bound requests to prevent an SLO’s controller
from:
• Requesting so few CPU resources that the associated workload
cannot perform reasonably well
• Requesting so many CPU resources that other workloads cannot
perform reasonably well
Use the mincpu and maxcpu keywords to state the minimum and
maximum allocations that the SLO’s controller can request. Because
these allocations are merely requests, the minimum allocation values
across all SLOs do not have to sum to 100%. (For information on setting
hard CPU limits, see “Specifying a group’s minimum CPU resources
(optional)” on page 175 and “Specifying a group’s maximum CPU
resources (optional)” on page 177.)
WLM grants requests based on the priority of the SLOs, their current
performance, and available resources.
