You can create additional Neutron availability zones with NSX-T Data Center by updating your VMware Integrated OpenStack deployment.

This procedure shows how to create an availability zone using the VMware Integrated OpenStack UI. You can also create an availability zone using the viocli update neutron command. See Create a Neutron Availability Zone with NSX-T Data Center for VMware Integrated OpenStack version 6.0.

Prerequisites

Create a separate DHCP profile and metadata proxy server for each availability zone. Availability zones can share an edge cluster or use separate edge clusters.

Procedure

  1. Log in to VMware Integrated OpenStack.
  2. Click OpenStack Deployment and select the deployment you want to configure.
  3. Click the Manage tab, then click Configure Neutron.
  4. Click the Add button and enter values for the availability zone.
    Option Description
    Availability Zone

    Enter a name for the availability zone. The alphanumeric string can include special characters (_) and (-).
    Default overlay TZ

    Select a default overlay transport zone for the availability zone.
    Default VLAN TZ

    Select a default VLAN transport zone for the availability zone.
    Default Tier0 router

    Select a default tier0 router for the availability zone.
    DHCP profile

    Select a DHCP profile configured for the availability zone.
    Metadata proxy

    Select the metadata proxy server configured for the availability zone.
  5. Click OK.

Results

The new availability zone is created.

Example: Creating Separate Availability Zones for N-VDS Standard and Enhanced Data Path

The following procedure implements separate availability zones so that you can deploy NFV workloads on N-VDS in enhanced data path mode and other workloads in standard mode. In this example, VMware Integrated OpenStack has been deployed with NSX-T Data Center in standard mode. The availability zones are configured on the same tier-0 router and edge cluster. The VMware Integrated OpenStack management network uses the IP address range 192.0.2.10 to 192.0.2.50.

  1. In NSX-T Data Center, configure an overlay transport zone and VLAN transport zone using N-VDS in enhanced data path mode. See Enhanced Data Path.

    The overlay transport zone is named nfv-overlay-tz and the VLAN transport zone is named nfv-vlan-tz.

  2. Create a DHCP profile for the new availability zone.
    1. In NSX Manager, select Networking > DHCP.
    2. In the Server Profiles tab, click Add.
    3. Enter nfv-dhcp as the name and select the existing edge cluster.
    4. Click Add.
  3. Create a metadata proxy server for the new availability zone.
    1. In NSX Manager, select Networking > DHCP.
    2. In the Metadata Proxies tab, click Add.
    3. Enter nfv-mdp as the name.
    4. Enter http://192.0.2.10:8775 as the Nova server URL.
    5. Enter mdpassword as the secret.
    6. Select the existing edge cluster.
    7. Click Add.
  4. Log in to VMware Integrated OpenStack.
  5. Select OpenStack Deployment and select the deployment you want to configure.
  6. Click the Manage tab, then click Configure Neutron.
  7. Click the Add button and enter values for the NFV availability zone.
    1. Enter nfv-az for the name of the availability zone.
    2. For the default overlay transport zone, select nfv-overlay-tz.
    3. For the default VLAN transport zone, select nfv-vlan-tz.
    4. Select a default tier0 router.
    5. For the DHCP profile, select nfv-dhcp.
    6. For the metadata proxy server, select nfv-mdp.
    7. Click OK.
  8. Create a network in the new availability zone.
    1. Log in to the Integrated OpenStack Manager as the root user.
    2. Load the cloud administrator credentials file. 
      sudo su -
source ~/cloudadmin.rc
    3. Create the network. 
      neutron net-create nfv-network --tenant-id nfv-project --availability-zone-hint nfv-az
