Setting utilization limits
Utilization limits allow you to set service level objectives for workloads based on overall system
utilization. For any given workload, you can specify one or more service level objectives. Global
utilization limits are applied to real workloads recognized by Virtualization Manager and to
workloads within scenarios to enable analysis of collected data (actual utilization) as it relates
to desired resource utilization. Within a scenario, when a service level objective cannot be met
for a workload, a visual indicator along with a warning message will be displayed when moving
a workload in a scenario. When making automated changes, such as the automated system
consolidation, these utilization limits are enforced in determining a solution. For more discussion
about utilization limits, see
“Utilization limits ” (page 27) .
IMPORTANT: For specific descriptions of each field or summary table on the user interface
screens, click the help topic link on the software screen for the task.
Getting there
Screens for modifying utilization limits can be accessed from the following locations:
•
the Virtualization Manager Configure menu on the Visualization tab
• the Modify menu on the Capacity Advisor tab
• the Edit menu on either the System or Workload tab of the Edit Scenario screen
TIP: For lists of all menu options for Capacity Advisor features, see “Menus & tabs” in Capacity
Advisor Help.
Setting global utilization limits
The default global utilization limits, which are applied in the absence of more specific limits, are:
◦
CPU utilization may not exceed 70% of allocation for more than 0
minutes.
◦ Memory utilization may not exceed 100% of allocation more than 0%
of the time.
Adding a utilization limit
1. From the Visualization tab, select Configure
→Global Utilization Limits...
2. For each metric for which you wish to add a utilization limit:
a.
Select the type of limit you wish to place, the utilization metric the limit applies to and
the utilization value above which the limit applies. For a Percent of Time Limit, enter
the percent of time the utilization value may be exceeded and a comment describing
the limit. For a Sustained Minutes limit, enter the duration in minutes the utilization
may be exceeded, and a comment describing the limit.
b. Click Add.
3. To see the current global utilization settings, click Revert.
To cancel your changes, click Cancel.
