By using the VMware Cloud Foundation API, you can deploy an example workload domain with 4 physical NICs per hosts, distributing the NICs between multiple vSphere Distributed Switch instances.

For traffic separation, two vSphere Distributed Switches handle the traffic in the initial cluster of the example workload domain - one for system traffic and one for application traffic. You assign a pair of physical NICs to each switch.

Procedure

  1. Send a query for unassigned hosts to SDDC Manager by using this request. 
    GET https://sddc-manager.vrack.vsphere.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 Step 3.

    computeSpec.clusterSpecs.hostSpecs.hostNetworkSpec.vmNics.id

    Physical NIC to use, for example, vmnic0.
