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 Importance field is specified.
- At least one of the CPU and DASD fields is specified.
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.
