The OpenStack Block storage project, Cinder, relies on Linux iSCSI by default. While that is fairly robust, you may need to integrate OpenStack into your existing environment or wish to use more advanced features provided by third-party storage devices. In this section, we will show you how to configure Cinder to use a different storage provider plugin.
Ensure that you are logged in to the Ubuntu host where the cinder-api service is installed, and have sourced in your OpenStack environment credentials.
