If you need to add a bunch of servers, say, of type XenApp, or ESX, there is a new, easy way to add them using the Bulk Add tool inside the GUI.
To get there - Admin -> Components -> Add/Modify
Then click on the Bulk Add/Modify button on the right side
First, download a sample CSV and change it to include your new components.
And, to get a feel for the fields, it helps to have added a few components manually to understand which fields are required and which are not.
After making the edits to the CSV file, then upload and add them. You are done. All the new systems will show up in the console. Next, you will need to configure them.
