By using the VMware Cloud Foundation API, you can deploy an example workload domain with 4 physical NICs per host.

In VMware Cloud Foundation 3.10, you can use the SDDC Manager public API to automate multiple physical NIC configurations when using for NSX-T.

In this example workload domain, for traffic separation, one vSphere Distributed Switch handles the system traffic for vSphere management, vSphere vMotion, and vSAN in the initial cluster of the example workload domain and one N-VDS handles the workload traffic, for example, NSX-T overlay. You assign a pair of physical NICs to each switch.

Procedure

  1. Send a query to SDDC Manager for unassigned hosts by using this request. 
    GET https://sfo01m01sddc01.sfo01.rainpole.local/v1/hosts?status=UNASSIGNED_USEABLE HTTP/1.1
Authorization:Basic admin rest_api_admin_password
  2. In the response, locate the fqdn parameter for the target hosts.
  3. Write down the GUID of each host object for the domain from the id field.
  4. Prepare a domain specification in JSON format according to the requirements of your environment and send it for validation to SDDC Manager.

    Most of the parameters are self-explanatory.

    Parameter

    Value

    computeSpec.clusterSpecs.hostSpecs.id

    GUIDs from 3.

    computeSpec.clusterSpecs.hostSpecs.hostNetworkSpec.vmNics.id

    Physical NIC to use, for example, vmnic0.
    Caution: Provide a valid licenseKey value. Otherwise, a failure in the workflow execution occurs. To resolve the issue, you must delete the partially created workload domain, and decommission and recommission the hosts.
