VxRack SDDC WLD Domain Expansion

In an earlier post, I created a new WLD. For argument’s sake let’s say my new WLD is now oversubscribed and I need to add some additional resources. Here we see we have two WLDs in operation. Click on the View Details to get more granular information on your WLDs


Here we can see both WLD’s. Select the WLD that you want to expand. I would like to expand the Demo Cluster.


Here we can see the detail on the WLD. Notice we have 3 nodes in total. Select the Expand Domain option.


Fill in your requirements in terms of resources. I have one spare node so I’m going to fully allocate all resources.


Review your settings and click apply and then confirm to expand your domain.



Now the Automation Takes over and completes these 21 tasks and adds a node to your WLD


  1. VRM: Import Input Parameters
