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.

Note: For NSX-T Data Center to work with vSphere Distributed Switch (VDS) version 7.0, you must install vSphere 7.0 and NSX-T 3.0 or later. Before deploying and configuring NSX-T Data Center, see Prepare a vSphere Distributed Switch for NSX-T.

Prerequisites

• Deploy vSphere, including vCenter Server and all ESXi hosts.

• Install NSX-T Data Center.
  1. Deploy NSX Manager. See NSX Manager Installation.
  2. Add your vCenter Server instance as compute manager. See Add a Compute Manager.

  3. For using NSX Manager cluster, you must deploy NSX Manager nodes. See Deploy NSX Manager Nodes to Form a Cluster from UI.

     Note: An NSX Manager cluster provides high availability for a single NSX-T Data Center instance. Multiple instances of NSX-T Data Center cannot be used with the same VMware Integrated OpenStack deployment.
  4. Deploy NSX Edge nodes. See Installing NSX Edge.
  5. If you are running vSphere 7.0 or later, add a new compute manager. See Add a Compute Manager.
• Generate the NSX-T root CA certificate using the cluster virtual IP. See Generating and Registering NSX Manager Certificate for Enterprise PKS.
