    This video is Part 5 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



    Okay, so instead of refreshing the hardware, let’s run through a scenario where we upgrade hardware – like adding more RAM. The setup for this plan is very similar to replacing hardware. 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 upgrade. I’ll be adding more RAM to the hosts in my lab cluster. Select “next” when done. Click the “Physical Machines” group. What we’ll be doing is selecting “Add new template” and building an identical server to what I have today, except for the RAM specs. If you don’t know the exact specs of your hardware today, you can use Operations Manager to find out. Navigate to the Inventory tab and find one of the hosts you’ll be upgrading. Expand the host and then expand the “Composed of” folder. By navigating to the Memory and PROC files I can see my hardware specs. For example, this host has 64GB of RAM and 8 Cores at 2.4GHz. Back to the Plan tab. My hosts’ RAM is going to be doubled to 128GB so I’ll plug in the appropriate value – notice that the units for RAM and CPU are in MB and Mhz respectively. Click “Create Template” and then select it from the drop down and “Replace”. Select Finish and Run. Using hosts with more RAM, Operations Manager will figure out how many are needed with that configuration. Let’s check out the results. If I upgrade to 128GB of RAM, Operations Manager can keep the environment healthy on just 4 upgraded servers. If I upgraded all 7 I would have even more capacity for growth. You can use the results and compare the cost to a complete hardware refresh, which is the plan we ran in the previous video.
