You can compose one or more servers by selecting the compute, network, and storage resources.


  • The translation layer must have been configured.
  • The composed server must meet the minimum hardware requirements. See the Planning and Preparation Workbook.


  1. In the navigation pane, click Administration > Composable Infrastructure.
  2. From the Available Resources table, select the zone where you want to compose a server. A zone corresponds to a physical boundary.
  3. Click Compose.
  4. In the Allocate Resources dialog box, select the compute for the server.
  5. Select the storage.
  6. Select the network interface.
    The Choose number of servers section displays the number of servers you can compose based on the selected resources.
  7. Select the number of servers you want to compose.
  8. Click Next.
  9. On the Review page, review the allocated resources to the servers.
    Click Back to make any changes.
  10. Click Compose.


The compose server task is displayed in the Tasks table at the bottom of the Composable Infrastructure page. Click the name of the task for more information. When the server is composed, it is added to the Server Composition Summary table.

If VMware Cloud Foundation does not receive a response from Redfish due to an external error, an error message is displayed. The hardware resources in the compose request are locked and cannot be used. You must free up these resources using the vendor UI. For more information, refer to the vendor documentation.

What to do next

  1. Image the composed servers. See Prepare ESXi Hosts for VMware Cloud Foundation.
  2. Commission the composed servers. See Commission Hosts.
