Overview of Working with Workloads | |
Workloads represent applications running on systems. The following
tasks are described: Creating a Workload | |
When you are modeling future configurations, you can create
new workloads to represent applications that will be added.
The workload can be based on either a static baseline or profile
data from an existing workload. Prerequisites. To create a workload in a scenario: Procedure 4-36 To Create a Workload You can create workloads from the System or Workload tab. If you want to preselect the system
to run the workload: If you are not on the System tab, click the System tab. The System tab will open,
listing the systems in the scenario. Click the check box preceding the
system you want to run the workload. A check mark will
fill the check box and the line containing the system
will be highlighted.
Select What-If Action Create Workload... from
the menu-bar. The Edit Scenario - Create Workload screen will be displayed. If you have not preselected the
system to run the workload, select a System. | | | |  | NOTE: You can move the workload later. | | | | |
Fill in the Workload name. The name must be unique on the
specified system. The only characters allowed are upper
and lower case alpha, numeric, and the dash and period. The first
character must be an alpha character. | | | |  | TIP: It is a good idea to make the names of workloads unique across
the scenario to allow them to be moved among systems. | | | | |
Add a detailed description of the
workload in the Workload Description field. Complete the definition of the
workload using the controls under Estimated Baseline. Click the ? for the screen for details on the
controls. If you have more workloads to create,
click the Apply button and repeat the preceding 4 steps, otherwise, proceed to the following step. Click the OK button. The Workload tab of the Capacity Advisor - Edit Scenario screen will open.
What Now? Once you have created a
workload, you might want to: Editing a Workload | |
When constructing a scenario, it is frequently necessary to
modify the characteristics of a workload to reflect future changes
in application or in the users of the application. There are
two types of workloads, those that reflect current workloads
on the system and those that are created in for a scenario.
While both can be edited, the characteristics that can be edited
are different for each. If you are editing a workload created for
a scenario, you can change the basis from static to workload
based and vice-versa. Prerequisites. To edit a workload in a scenario: Procedure 4-37 To Edit a Workload If you are not on the Workload tab, click the Workload tab. The Workload tab will open,
listing the workloads in the scenario. Click the check box preceding the
name of the workload you wish to edit. A check mark will appear in the check box and the row containing
the workload will be highlighted to indicate selection. Select What-If ActionEdit Workload... from the
menu-bar. The Edit Scenario - Edit Workload screen will be displayed in a new window. If you are editing a workload representing
a current workload, modify the Offset Hours, CPU workload
multiplier and Memory
workload multiplier as appropriate. For details
on the meaning of the controls, access help on the screen
by clicking the ? button. If you are editing a workload created
for this scenario, modify the Estimated Baseline parameters as appropriate.
For details on the meaning of the controls, access help on the screen
by clicking the ? button. Click the OK button. The Workload tab of the Capacity Advisor - Edit Scenario screen will open.
What Now? Once you have edited a workload,
you might want to: Moving a Workload | |
Moving workloads allows
you to redistribute workloads, including virtual equivalents
of existing systems, across physical servers. While moving workloads,
you can compensate for differences among systems by adjusting
platform multiplier values. These values can be determined by
running applications on systems representing the hardware and
software configurations being used. Prerequisites. To move a workload in a scenario: Procedure 4-38 To Move a Workload If you are not on the Workload tab, click the Workload tab. The Workload tab will open,
listing the workloads in the scenario. Click in the check box preceding
the workload you wish to move. A check mark will appear in the check box and the row containing
the workload will be highlighted. Select What-if ActionMove Workload... from the
menu-bar. The Edit Scenario - Move Workload screen will be displayed, with a list of all the systems
available to host the workload. | | | | | NOTE: Bar-graphs representing the change in CPU Utilization and Memory Utilization that will occur if the
workload is moved to each of the VM Hosts provide a quick
estimate of how the workload will “fit” on
each of the host systems. | | | | |
If the system the workload data
was collected on has significant differences from the system
on which you intend to run the workload, you can use the CPU Platform Multiplier and
Memory Platform Multiplier to
adjust for differences between the characteristics of the
two systems. To do so: Modify the values of the CPU Platform Multiplier and/or Memory Platform Multiplier as appropriate. For details on the meaning of the
controls, access help on the screen by clicking the
? button. Click the Refresh button to update the CPU Utilization and Memory Utilization bar-graphs. The screen will gray out while the calculations are being
performed.
Click in the circle preceding the
name of the system that will be the new host for the workload. The circle will be filled in and the row containing the system
will be highlighted to indicate the selection. Click the OK button. The Workload tab of the Capacity Advisor - Edit Scenario screen will open.
What Now? Once you have moved a workload,
you might want to: Parking a Workload | |
When constructing a scenario, it can be desirable to temporarily
remove the effects of workloads to reflect potential changes,
without permanently removing the workloads. This is referred
to as “parking” the workloads. Prerequisites. To park workloads in a scenario: Procedure 4-39 To Park Workloads If you are not on the Workload tab, click the Workload tab. The Workload tab will open,
listing the workloads in the scenario. Click the check boxes preceding
the names of the workloads you wish to park. Check marks will appear in the check boxes and the rows containing
the workloads will be highlighted, to indicate selection. Select What-If ActionPark Workloads... from
the menu-bar. The Edit Scenario - Park Workloads screen will be displayed. Confirm that the workloads listed
under Workload Name hosted on the systems listed under Contained
In are the workloads you wish to park. Click the OK button. The Workload tab of the Capacity Advisor - Edit Scenario screen will open.
What Now? Once you have parked a workload,
you might want to: Removing a Workload | |
When working with a scenario, it is sometimes desirable to remove
workloads to reflect potential changes. Prerequisites. To delete workloads from a scenario: Procedure 4-40 To Delete Workloads If you are not on the Workload tab, click the Workload tab. The Workload tab will open,
listing the workloads in the scenario. Click the check boxes preceding
the names of the workloads you wish to remove. Check marks will appear in the check boxes and the rows containing
the workloads will be highlighted to indicate selection. Select What-If ActionDelete Workloads... from
the menu-bar. The Edit Scenario - Delete Workloads screen will be displayed. Confirm that the workloads listed
under Workload Name hosted on the systems listed under Contained
In are the workloads you wish to delete. Click the OK button. The Workload tab of the Capacity Advisor - Edit Scenario screen will open.
What Now? Once you have removed a
workload, you might want to: |
