The following diagram shows the logical architecture of this solution:
PowerFlex Manager (PFxM) is used to deploy a PowerFlex Storage Only (SO) cluster on four bare metal servers followed by the deployment of the PowerFlex CSI driver on an OpenShift Cluster, allowing the OpenShift users to provision and manage storage volumes dynamically. For more information about the configuration of OpenShift nodes and the PowerFlex nodes that are used in this solution, see Configuration details.
