As part of the What-If analysis for physical infrastructure planning for traditional environments, Infrastructure Planning: Traditional pane is what you use to fill in the details of your What-If scenario. You select where to add or remove hosts, use an existing server type, or configure it yourself (when you add capacity), and establish a time frame.

Where You Find Physical Infrastructure

At the What-If Analysis screen, click Add Hosts or Remove Hosts in the Infrastructure Planning: Traditional pane.

Table 1. Add Hosts Options
Option Description
Scenario Name Name of your scenario
Location Where do you want to add capacity? Select from the list of existing data centers, then select the cluster where you want one or more servers to reside.
Server Details Clicking Select Server displays the Select Server Type dialog box, where you can select a commercial brand server or configure a custom server.

Number of Servers to add: increment the Quantity counter up to the number of servers you want.

Start Date/End Date Select from pop-up calendars the start and end date for the What-If scenario.
Run Scenario Click to run the scenario. The system calculates the cost of the scenario and determines any new time remaining number.
Save Save the scenario.
Cancel Cancel the scenario.

The system displays immediately the impact on cluster size of the additional CPU and memory, and shows the total cost of adding the specified capacity. The system also shows in graphical form whether adding the new capacity extends the time remaining before CPU or memory runs out.

Table 2. Remove Hosts Options
Option Description
Scenario Name Name of your scenario
Location From where do you want to remove capacity? Select from the list of existing data centers, then select the cluster from where you want to remove one or more servers.
Server Details Clicking Select Server displays the Select Server Type dialog box, where you can select only the server types that exist in your selected cluster.

The number of servers that you plan to remove is limited by the number of selected server types available in the selected cluster.

Start Date/End Date Select from pop-up calendars the start and end date for the What-If scenario. You can select to keep the end date blank.
Run Scenario Click to run the scenario. The system determines any new time remaining number.
Save Save the scenario.
Cancel Cancel the scenario.

The system displays the time remaining and the impact on CPU and memory with reduced capacity. The system also shows in graphical form whether removing capacity decreases the time remaining before CPU or memory runs out.

You can also see that the cost is based on the original purchase cost.
