If you have chosen to deploy VMware Integrated OpenStack with NSX-T Data Center, configure your environment as described in the following procedure.

Prerequisites

  • Deploy vCenter Server and all ESXi hosts.
  • Deploy and configure NSX-T Data Center and all related nodes. See Configure NSX-T Data Center for OpenStack.
  • Open the TCP and UDP ports required by VMware Integrated OpenStack. See Required Network Ports.
  • Create a PTR record associating the IP address planned for the OpenStack Management Server with its FQDN, and ensure that the OpenStack Management Server can connect to a DNS server.
  • Obtain the following NSX-T Data Center parameters. You configured these parameters when deploying NSX-T Data Center.
    • FQDN or IP address of the NSX Manager
    • Username and password to access the NSX Manager
    • Overlay transport zone
    • VLAN transport zone
    • Tier-0 router
    • DHCP profile
    • Metadata proxy server and value of the secret parameter

Procedure

  1. Configure the management, API access, transport, and external networks and assign a dedicated VLAN to each.
    1. Ensure that the management and API access networks have sufficient IP addresses to support your deployment.
      The required size of these networks depends on the deployment mode and on whether you want to deploy Ceilometer.
      Deployment Mode IP Address Requirements
      HA
      • Management network: 11 contiguous IP addresses
      • API access network: 2 contiguous IP addresses
      HA with Ceilometer
      • Management network: 15 contiguous IP addresses
      • API access network: 2 contiguous IP addresses
      Compact or tiny
      • Management network: 4 contiguous IP addresses
      • API access network: 1 IP address
      Compact or tiny with Ceilometer
      • Management network: 8 contiguous IP addresses
      • API access network: 1 IP address
      Important: Ensure that the management network and API access network can each be expanded to twice the original number of IP addresses during upgrades. When upgrading VMware Integrated OpenStack, you will temporarily require sufficient IP addresses to support two deployments.
    2. Ensure that the vCenter Server, NSX Manager, and NSX Controller instances can access the management network on Layer 2 or Layer 3.
    3. Ensure that the API access network is externally accessible.
    4. On the transport network, set the Maximum Transmission Unit (MTU) to 1600 bytes.
  2. On your vCenter Server instance, create a data center.
  3. In the data center, create the management cluster.
    • For HA deployments, the cluster must contain at least three hosts and at least one datastore.
    • For compact or tiny deployments, the cluster must contain at least one host and at least one datastore.
  4. Create the compute cluster.
    The compute cluster must contain at least one host and at least one datastore.
  5. (Optional) Create the edge cluster.
    If you create an edge cluster, it must contain at least one host and at least one datastore.
  6. On the management and compute clusters, open the Configure tab and click the Edit... button.
    1. On the vSphere DRS page, select Turn ON vSphere DRS.
    2. On the vSphere Availability page, select Turn ON vSphere HA.
    3. On the Failures and Responses page, select Enable Host Monitoring.
    4. Expand the Host Failure Response section and set Default VM Restart Priority to High.
    5. Expand the VM Monitoring section, select VM Monitoring and Application Monitoring, and set Heartbeat monitoring sensitivity to High.
    6. On the Admission Control page, ensure that admission control is enabled.
  7. On each host in each cluster, enable virtualization hardware extensions in the BIOS.
  8. On the VMkernel adapter for the management network, enable vMotion.
  9. In your data center, create one or more distributed switches for your management, compute, and edge clusters.
    A distributed switch can be shared among clusters that are Layer 2 adjacent. Create a separate distributed switch for any cluster that is not Layer 2 adjacent to the other clusters.
  10. On each distributed switch created, create the management port group and tag it with the VLAN ID assigned to the management network.
  11. On the distributed switch for the management nodes, create the API access port group and tag it with the VLAN ID assigned to the API access network.
  12. On the distributed switch for the edge nodes, create the external port group and tag it with the VLAN ID assigned to the external network.

What to do next

After you have prepared your environment, you can install VMware Integrated OpenStack. See Installing VMware Integrated OpenStack.
