2.1. Red Hat OpenStack Platform Director

Red Hat OpenStack Platform 8 brings several notable new enhancements for the director:
  • Broader support for Cisco Networking through Neutron, including:
    • N1KV ML2 plug-in
    • N1KV VEM and VSM modules
    • Nexus 9K ML2 plug-in
    • UCSM ML2 plug-in

  • New parameters for network configuration in environment files, including type_drivers, service_plugins and core_plugin.

  • Big Switch Networks support, including Big Switch ML2 plugin, LLDP, and bonding support

  • VXLAN is now the default overlay network. This is because VXLAN performs better and NICs with VXLAN offload are more common.

  • MariaDB’s maximum number of connections now scales with the number of CPU cores in the Controller nodes.

  • The director can now set RabbitMQ’s file descriptor limits.

  • SSL support for Red Hat OpenStack Platform components deployed on nodes in overclouds.

  • IPv6 support for overcloud nodes.
