Configure NSX-T Data Center for OpenStack

If you want to use NSX-T Data Center as the networking solution for VMware Integrated OpenStack, deploy and configure NSX-T Data Center as described in the following procedure.

Prerequisites

• Deploy and configure vSphere, including vCenter Server and all ESXi hosts. See ISHPUBLMODULEMISSING.html#GUID-47907885-231C-4A3E-A8ED-2FAFF249448B.

• Install NSX-T Data Center.
  1. Deploy NSX Manager. See NSX Manager Installation.
  2. Deploy NSX Controller instances. See NSX Controller Installation and Clustering.
  3. Join each NSX Controller with the NSX Manager. See Join NSX Controllers with the NSX Manager.
  4. Initialize the control cluster. See Initialize the Control Cluster to Create a Control Cluster Master.
  5. If you deployed multiple NSX Controller instances, join them to the cluster. See Join Additional NSX Controllers with the Cluster Master.
  6. (Optional) Add your vCenter Server instance as a compute manager. See Add a Compute Manager.
  7. Deploy NSX Edge nodes. See NSX Edge Installation.
