    This video is Part 4 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



    Let’s head on back into the Plan tab. We’ve got legacy hardware that’s got to go – and we need to know how many new hosts to purchase. And maybe we’re debating between a few different hardware vendors with different specs. We can run a few different plans and compare. Let’s use the New Plan wizard to get started – click on the green plus button. Now choose, “Reconfigure Hardware.” Expand the Cluster drop down and select the cluster or clusters you would like to refresh. You can multi-select by using the Control and Shift keys. I’ll be upgrading my Lab cluster. Select “next” when done. You’ll notice the default selection on the left is “Replace Host Using a Template.” If you’re thinking about changing your Storage, you can select “Replace Storage Using a Template” as well. Click the “Physical Machines” group. Now we’ll use the Template dropdown to choose what hardware we’ll be upgrading to. Operations Manager comes with a few preconfigured hardware templates. You can select a model from the list, or scroll all the way down and select “Add New Template” to add your own. If you select “Add New Template” fill in the details of the hardware you would like to upgrade to. You can even input the cost of the hardware and have Operations Manager do some easy math for you. I’ll be using one of the preconfigured templates. Click “replace,” then “finish,” and now “run.” Let’s check out the results. With the particular hardware I’ve chosen, Operations Manager can keep the environment healthy on just 4 servers – which is 3 less servers than I have today. At the bottom I can see the total investment number based on the cost of each new host. You can now run this plan again choosing a different hardware configuration and compare.
