4 Using Imported Data in Scenarios

This section describes how to use workload data from non-VSE systems in a Capacity Advisor scenario. To import non-VSE workload data, do the following:

In the Capacity Advisor GUI, select a Scenario into which to import the non-VSE workload. Use the ModifyEdit Scenario menu pick to launch the Edit Scenario screen.
In the Edit Scenario screen, select the What-If ActionCreate Workload menu pick. This action displays the “Edit Scenario - Create Workload” screen. In this screen, activate the radio button "Use profile data from workload" and choose a non-VSE workload from the "Import Profile Values" workload list. Choose the name of the non-VSE workload to be imported from the drop-down list. See Figure 2 for an example of the Create Workload screen. After filling in the other fields in the form, click OK; the what-if workload is then listed in the Edit Scenario page.
The new workload can be moved to any system, real or what-if, in the scenario.




	IMPORTANT: When moving imported workloads, it is crucial to enter a platform CPU multiplier. Capacity Advisor uses a multiplier computed from the clock speed of the system to scale a workload’s demand profile when it is moved from one system to another. Such an estimate gives numbers that are usually accurate within 10% when moving workloads within the PA family of processors or within the Integrity family of systems. However, this estimate can be radically wrong when moving a workload from one processor family to another. Integrity systems often perform twice as much work as ProLiant systems with the same clock speed and number of cores. Consult benchmarks when moving workloads from one processor family to another. Either run your own benchmark using your application, or consult industry standard benchmarks that are run on a wide range of systems. Benchmarks can be found at http://spec.org.
