Capacity Planning Scenarios Part 7: Workload Migration (Failover) – Do Not Add Hardware

    This video is Part 7 of a series of videos outlining how to accomplish different capacity planning use cases in VMTurbo Operations Manager. Please see this post for all videos in the series: Video Tutorial: Capacity Planning Use Cases



    In this failover scenario, let’s tell VMTurbo that it shouldn’t suggest to add more hardware. I would like to simulate what the environment will look like if I had to run all these workloads on the hardware that exists today. Let’s setup the scenario.

    Click on the green plus button to open up the Plan Wizard. Select the last option, “Workload Migration.” Now we’re asked “which cluster will everything be moved to?” – “the destination cluster”. Select your destination cluster and then click Next. Select the group of workloads that will be migrated over, then drag and drop the group over to the “Plan Inventory” window. Click Finish.

    Before clicking “Run”, go to Advanced Settings and click “Edit”. Select the tab, “Action Settings.” Now uncheck “Allow Host Provisioning” and click Apply. This tells VMT to not suggest adding more hardware. Close the dialog box. Finally, make sure “Ignore constraints” is checked. This tells VMTurbo to ignore cluster boundaries – which is required in a scenario like this. Now click “Run”

    Based on the additional workload that has migrated into this cluster, VMTurbo has rearranged the workloads to run on the existing hardware today. We may see an undesirable state here – but that’s because we’ve told VMTurbo to not add any hardware if resources are constrained – so that’s expected. The todo list highlights how existing workload will be distributed to accommodate the migrated workloads.
