Add or Remove HCI Nodes

As part of the what-if analysis for physical infrastructure planning for hyperconverged environments, the Infrastructure Planning: Hyperconverged pane is what you use to fill in the details of your what-if scenario. When you add an HCI node, you can select an existing server type from your vSAN activated data center and change the number of instances of this server to calculate storage, compute capacity, time remaining, and cost. You can run the Remove HCI Nodes scenario to see the capacity changes after you remove HCI nodes from your data center.

Where You Find Workload Planning

At the What-If Analysis page, click Add HCI Nodes or Remove HCI Nodes in the Infrastructure Planning: Hyperconverged pane.

Table 1. Add HCI Nodes Options

Option	Description
Scenario Name	Name of your scenario.
Location	Where do you want to add the HCI node? Select from the list of existing data centers. You must also choose the exact cluster where you want the HCI node to reside.
Server Details	Allows you to select an existing server type to calculate capacity, time, and storage remaining based on the number of instances of the server.
Number of servers to add	How many instances of the server do you want to add? Note: Only 60 new hosts can be added to the specified vSAN cluster as the maximum allowed is 64 hosts.
Start Date/End Date	Select from pop-up calendars the start and end date for the workload. The end date cannot be later than one year from the current date.
Run Scenario	Click to run the scenario. The system calculates whether it fits into the location you selected.
Save	Save the scenario.
Cancel	Cancel the scenario.

Table 2. Remove HCI Nodes 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 the server(s).
Server Details	Clicking Select Server displays the Select Server Type dialog box, where you can choose 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.
Implementation date/End Date (optional)	Select from pop-up calendars the start and end date for the what-if scenario. You can choose 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.
