<div class="paragraph">
<p>This hands-on workshop is for both system administrators and application developers interested in learning how to deploy and manage OpenShift Container Storage (OCS). In this lab you will be using OpenShift Container Platform (OCP) 4.x and the OCS operator to deploy Ceph and the Multi-Cloud-Gateway (MCG) as a persistent storage solution for OCP workloads. This instruction was developed using the RHPDS <code>OpenShift 4.2 Workshop</code>.</p>

It would be a good practice to add a unique label to OCP nodes that are to be used for creating the <code>Storage Cluster</code> prior to this step so they are easy to find in list of OCP nodes.
