Server Complex Properties window: VMRM page

Use the VMRM page of the Server Complex Properties window to specify the VMRM goals for the Linux guest systems in the server complex. The VMRM (VM Resource Manager) performance goal specifies the percentage of CPU and IO resources for a group of virtual machines in a z/VM.

Fields

A VMRM goal is considered valid if and only if both:

The VMRM page in the Server Complex Properties window contains the following fields:

Whole Server Complex
Select this radio button to set/view the properties for the whole server complex. This lets you set a common VMRM goal for all the Linux guest systems in the server complex. When this radio button is selected, properties that were specified for each tier separately are ignored.
Specific Tier
Select this radio button to set/view the properties for a specific tier in the server complex. This lets you set a separate VMRM goal for the Linux guest systems in each tier. When this radio button is selected, the Tiers List is displayed.
Tiers List
Choose a tier from the drop-down list of server complex tiers to set/view the properties for that tier. This field only appears when the Specific Tier radio button is selected.
CPU
Type the VMRM CPU velocity goal. This must be an integer from 1 to 100.
DASD
Type the VMRM DASD velocity goal (IO priority). This must be an integer from 1 to 100.
Importance
Type the VMRM importance of the goal. This must be an integer from 1 to 10, where 10 is the most important.
OK
Applies the modified values, in all the configuration domains, after checking the consistency of the actual configuration against the old server complex properties.
Apply
Applies the VMRM goal without a consistency check.
