On Demand Placement > Creating On Demand Placement Scenario

Creating On Demand Placement Scenario

On Demand Placement enables you to add new VMs to the existing VM hosts or VMware Clusters without affecting the current VM placement.

The CPU, memory, and storage graphs display the demand-capacity analysis for the selected Groups. If the capacity of a resource fails to meet the demand, then the optimization analysis might fail. In this case, you need to add more capacity to the resources. Additionally, you can also see the oversubscription that is defined for the selected Groups.

To create and run an On Demand Placement scenario:

  1. Define a name and description for the On Demand Placement scenario.
  2. Define the following:
  3. Select Use SPECint for CPU normalization if you want to normalize the CPU speed.
  4. Define the CPU, memory, and storage subscription percentage.
    Subscription of resources is the percentage of capacity allocated to VMs out of the total capacity.
  5. Click Run On Demand Placement to generate the On Demand Placement scenario results.
  6. Click Save to DB to save the On Demand Placement scenario in the database.

On Demand Placement Results

SHO displays the On Demand Placement results in the Results table. The Results table shows the list of the newly created VMs and the recommended Clusters on which they can be placed. Additionally, it shows the remaining capacity, in terms of the number of VMs, on each of the host before and after the new VM placement.

The remaining capacity is calculated using reference VM size set under the General tab on the Configurations View page. For more information about setting the reference VM size, see Defining Reference and Custom VMs.

You can view the list of On Demand Placement scenarios on the Scenario Manager page.
