For network and security purposes, you can create and associate an NSX-T cloud account with a vCenter cloud account.

To facilitate fault tolerance and high availability in deployments, each NSX-T data center endpoint represents a cluster of three NSX managers.
  • vRealize Automation can point to one of the NSX managers. With this option, one NSX manager receives the API calls from vRealize Automation.
  • vRealize Automation can point to the Virtual IP of the cluster. With this option, one NSX manager assumes control of the VIP. That manager receives the API calls from vRealize Automation. In case of failure, another node in the cluster assumes control of the VIP and receives the API calls from vRealize Automation.

    For more information about VIP configuration, see Configure a Virtual IP (VIP) Address for a Cluster in the NSX-T Data Center Installation Guide at VMware NSX-T Data Center Documentation.

  • vRealize Automation can point to a load balancer VIP to load-balance the calls to the three NSX managers. Using this option, all three NSX managers receive API calls from vRealize Automation.

    You can configure the VIP on a third-party load balancer or on an NSX-T load balancer.

    For large scale environments, consider using this option to split the vRealize Automation API calls among the three NSX managers.



  1. Select Infrastructure > Connections > Cloud Accounts and click Add Cloud Account.
  2. Select the NSX-T account type and enter the host IP address for the NSX-T endpoint manager instance or VIP (see above).
  3. Enter your NSX administrator credentials and click Validate.

    The assets associated with the account are collected.

    If the NSX host IP address is not available, validation fails.

  4. If available, select the vCenter endpoint that represents the vCenter cloud account that you are associating with this NSX-T cloud account.
  5. If you want to add tags to support a tagging strategy, enter capability tags.
  6. Click Save.
