In the VI Configuration wizard, you specify the storage, name, compute, and networking details for the VI workload domain. Based on the selected storage, you provide vSAN parameters, NFS share details, or VMFS on FC datastore information. You then select the hosts and licenses for the workload domain and start the creation workflow.

The workflow automatically:
  • Deploys an additional vCenter Server Appliance for the new workload domain within the management domain.

    By using a separate vCenter Server instance per workload domain, software updates can be applied without impacting other workload domains. It also allows for each workload domain to have additional isolation as needed.

  • Connects the specified ESXi servers to this vCenter Server instance and groups them into a cluster. Each host is configured with the port groups applicable for the workload domain.
  • Configures networking on each host.
  • Configures vSAN, NFS, or VMFS on FC storage on the ESXi hosts.
  • For the first VI workload domain, the workflow deploys a cluster of three NSX Managers in the management domain and configures a virtual IP (VIP) address for the NSX Manager cluster. The workflow also configures an anti-affinity rule between the NSX Manager VMs to prevent them from being on the same host for High Availability. Subsequent VI workload domains can share an existing NSX Manager cluster or deploy a new one. In order to share an NSX Manager cluster, the workload domains must use the same update manager. The workload domains must both use vSphere Lifecycle Manager (vLCM) or they must both use vSphere Update Manager (VUM).
  • During bring-up with application virtual networks (AVNs), Cloud Foundation creates a two-node NSX Edge cluster on the management domain for use by the vRealize Suite components. You can add additional NSX Edge clusters on the management domain. By default, workload domains do not include any NSX Edge clusters and are isolated. Add one or more Edge clusters to a workload domain to provide north-south routing and network services. See Deploying NSX-T Edge Clusters.
    Note: Multiple Edge clusters cannot reside on the same vSphere cluster.
  • NSX Managers deployed as part of a VI workload domain are configured to periodically get backed up to an SFTP server. By default, these backups are written to an SFTP server built into SDDC Manager, but you can register an external SFTP server for better protection against failures. See Configure an External SFTP Server for File-Based Backups. SDDC Manager uses either the built-in or external SFTP server with all currently deployed NSX Managers and when deploying additional NSX Managers.
  • Licenses and integrates the deployed components with the appropriate pieces in the Cloud Foundation software stack.

The result is a workload-ready SDDC environment.

Note: You can only perform one workload domain operation at a time. For example, while creating a new workload domain, you cannot add a cluster to any other workload domain.
