10 To view the eect of your selections in the visualization chart, click Save project and continue editing.
With the Capacity Container set to Most Constrained, the visualization chart might indicate a CPU
shortfall when you implement the project scenario. This shortfall might occur because the CPU
allocation might be greater than the available capacity. In this case, you might need to add CPU capacity
before you implement the project scenario.
11 When you are satised with the capacity forecast based on your seings, click Save to add the scenario
to the project.
12 On the Projects tab, click your project in the list and drag it to the area above the project list.
vRealize Operations Manager applies your project and scenario to the visualization chart. The capacity
forecasted in the project appears as a gray line in the chart.
What to do next
Add the scenario named Add Demand: add percentage of demand to the project, and set the Capacity
Container to Disk Space Allocation. The visualization chart might indicate that when you implement the
project scenario, you have a disk space shortfall. In this case, you might need to add disk space capacity
before you implement the project scenario.
In the visualization chart, evaluate the current available capacity with the actual capacity required if you
change your environment as dened in your project. Determine whether to commit the project so that it
reserves the capacity required for the hardware change.
Planning Virtual Machine Projects and Scenarios
Virtual machine projects help you assess the consequences of changing resources on virtual machines
without applying the changes to your virtual environment. Before you apply changes to your virtual
environment, you can create sample virtual machine projects to model adding or removing virtual machines
to a host or a cluster.
n
Create a Virtual Machine Project Using Populated Metrics on page 88
You can create a project scenario that uses an existing virtual machine prole as a model. The project
scenario simulates the resource requirements when you add one or more virtual machines to a host or
cluster.
n
Create a Sample Project for a New Virtual Machine on page 89
Virtual machine projects assess the consequences of adding a new virtual machine to a cluster or host,
without applying the actual changes to your virtual environment.
n
Create a Sample Project to Simulate Removing a Virtual Machine on page 90
You can create a project that simulates removing one or more virtual machines from a host or a cluster.
You might remove virtual machines when you no longer need them, or when you must move them.
Create a Virtual Machine Project Using Populated Metrics
You can create a project scenario that uses an existing virtual machine prole as a model. The project
scenario simulates the resource requirements when you add one or more virtual machines to a host or
cluster.
When you congure the seings in a project scenario to add virtual machines, you can populate the resource
values for the planned virtual machine from an existing prole. Or, you can copy the values from an existing
virtual machine.
To calculate the capacity metrics values for the virtual machine, vRealize Operations Manager partitions the
capacity for CPU, memory, and disk dimensions, according to the prole that you select.
For information about CPU and memory maximums, see the VMware vSphere documentation.
