<title>Configure a Block Storage service controller</title>
<note>
<para>This scenario configures OpenStack Block Storage
services on the <glossterm baseform="controller node">Controller node</glossterm>

second node provides storage through the <systemitem

<para>For
instructions on how to configure the second node, see <xref

<para>You can configure OpenStack to use various storage systems.
