To increase the physical resources that are associated with a management domain, you can expand that management domain.

About this task

Each physical rack in your Cloud Foundation installation has a management domain. When a management domain is expanded, the expansion process uses hosts that reside in the same physical rack in which that management domain resides.

You expand a management domain from its details page.


  1. From the SDDC Manager dashboard, navigate to details page for the management domain you want to expand.
  2. In the Domain Details page, click EXPAND DOMAIN.

    The Expand Domain wizard opens.

  3. At the Resources step, specify the resources to add to the management domain.



    Expand Method - By Capacity

    Type the amount of CPU, memory, and storage capacity to add to the management domain.

  4. Proceed to the next step by clicking Next.
  5. At the Review step, review the displayed information and then click Apply to begin the expansion workflow.

    The Review page lists the hosts that the expansion process will add to the management domain to accommodate the requested capacity and the physical rack details for those hosts.


    When expanding a management domain, the expansion process considers hosts only from the same physical rack in which that management domain resides.


A message indicating the status of the workflow appears at the top of the Domain Details window. To confirm the progress of the expansion workflow's tasks, navigate to the System Status page and and drill-down to the details about the workflow.
