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 vSphere, including vCenter Server and all ESXi hosts.

• 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. (NSX-T Data Center 2.4 or later) If you want to use an NSX Manager cluster, deploy additional 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.
  8. Deploy NSX Edge nodes. See NSX Edge Installation.

Procedure

1. Log in to the NSX Manager as an administrator.
2. Add your ESXi hosts to the NSX-T Data Center fabric.

   3. Enter the name, management IP address, user name, and password of the host.
      You can also enter a host thumbprint. If you do not enter a thumbprint, NSX-T Data Center will prompt you to use the default thumbprint provided by the host.

What to do next

Prepare to Install VMware Integrated OpenStack with NSX-T Data Center

VMware Integrated OpenStack can generate a new DHCP profile and metadata proxy server for your deployment. You are no longer required to configure these items in advance.

If you want to manually configure a metadata proxy server in NSX-T Data Center before deployment, specify the first IP address in the VMware Integrated OpenStack management network IP range as the URL for the Nova server.
