This course is part of the emerging technology series of courses from Red Hat. While Red Hat® OpenStack Administration (CL210) covers scaled out Nova compute nodes; this course takes scalability to the next level by creating a separate storage node and a separate network node to provide better scalability and separation between functions. This course is designed for storage administrators, network administrators, or cloud operators who are intending to scale out an OpenStack environment or integrate their network or storage into an OpenStack environment.
You will learn about the architecture and installation of Red Hat Ceph Storage as well as the integration of Red Hat Ceph Storage into Red Hat Enterprise Linux OpenStack Platform, covering integration with the Glance image service, integration with the Cinder block storage service, and replacing the Swift object storage service. This course also covers networking in the OpenStack environment, including creation of a separate network node, coverage of VLAN, VXLAN, and GRE, networks, subnets, floating IP address and other software-defined network (SDN) items, as well as distributed virtual routing (DVR).
There are no prerequisites for this course.
Experienced Linux system administrators responsible for managing OpenStack environments who are interested in learning how to configure a scalable and distributed storage as a storage backend for OpenStack and use the advanced features offered by OpenStack Neutron.
