⢠Cisco OpenStack Installer (Cisco OSI) simplifies the OpenStack
installation process
⢠Configure an initial Build server outside the Openstack cluster
environment, After that it is used as an out-of-band automation and
management workstation to bring up, control, and reconfigure (if
necessary) the nodes of the OpenStack cluster.
⢠This build server primarily functions as a Puppet server for software
deployment and configuration management onto the OpenStack cluster,
as well as a Cobbler installation server to manage the PXE boot used for
rapid bootstrapping of the OpenStack cluster.
⢠VSM, VEM and VxLAN-VLAN Gateway Installation
