You can add the primary VxRail cluster to a VI workload domain using the SDDC Manager UI.


  • Create a local user in vCenter Server. This is required for the VxRail first run.
  • Image the VI workload domain nodes. For information on imaging the nodes, refer to Dell EMC VxRail documentation.
  • Perform a VxRail first run of the VI workload domain nodes using the vCenter Server for that workload domain. For information on VxRail first run, refer to the Dell EMC VxRail documentation.


  1. In the SDDC Manager UI, click Inventory > Workload Domains.
  2. In the workload domains table, click the vertical ellipsis (three dots) next to the VI workload domain in the Activating state and click Add VxRail Cluster.
  3. On the Discovered Clusters page, select a VxRail cluster and click Next.
  4. On the Discovered Hosts page, enter the SSH password for the discovered hosts and click Next.
  5. On the VxRail Manager page, enter the Admin and Root user names and passwords.
  6. On the Thumbprint Verification page, click Confirm fingerprint icon to confirm the SSH thumbprints for VxRail Manager and the ESXi hosts.
  7. The Networking page displays all the networking details for the cluster.
    1. Choose to create a new NSX Manager cluster or reuse an existing one.
      For the first VI workload domain, you must create an NSX Manager cluster.
    2. If you are reusing an existing NSX Manager cluster, select the cluster and click Next.
      The networking information for the selected cluster displays and cannot be edited.
    3. If you are creating a new NSX Manager cluster, enter the VLAN ID for the NSX-T host overlay (host TEP) network.
    4. Select the IP allocation method.
      Note: You can only use a static IP pool for the management domain and VI workload domains with uniform L2 clusters. For L3 aware or stretch clusters, DHCP is required for Host Overlay Network TEP IP assignment.
      Option Description
      DHCP With this option VMware Cloud Foundation uses DHCP for the Host Overlay Network TEPs.

      A DHCP server must be configured on the NSX-T host overlay (Host TEP) VLAN. When NSX creates TEPs for the VI workload domain, they are assigned IP addresses from the DHCP server.

      Static IP Pool With this option VMware Cloud Foundation uses a static IP pool for the Host Overlay Network TEPs. You can re-use an existing IP pool or create a new one.
      To create a new static IP Pool provide the following information:
      • Pool Name
      • Description
      • CIDR
      • IP Range.
      • Gateway IP
      Make sure the IP range includes enough IP addresses for the number of hosts that will use the static IP Pool. The number of IP addresses required depends on the number of pNICs on the ESXi hosts that are used for the vSphere Distributed Switch that handles host overlay networking. For example, a host with four pNICs that uses two pNICs for host overlay traffic requires two IP addresses in the static IP pool.
      Note: You cannot stretch a cluster that uses static IP addresses for the NSX-T Host Overlay Network TEPs.
    5. Provide the NSX Manager cluster details:
      • NSX Manager Virtual IP (VIP) address and FQDN
      • IP addresses and FQDNs for three NSX Managers (nodes)
      • NSX Manager Admin password
    6. Click Next.
  8. Enter the license keys for NSX-T Data Center and VMware vSAN and click Next.
  9. Review the details and click Next.
  10. On the Validation page, wait until all of the inputs have been successfully validated.
    If validation is unsuccessful, you cannot proceed. Use the Back button to modify your settings and try again.
  11. Click Finish.
