== Introduction
|
|
|
|
The {ibm-power-server-name} Block CSI Driver is installed through the {ibm-power-server-name} Block CSI Driver Operator and the operator is based on `library-go`. The {product-title} `library-go` framework is a collection of functions that allows users to build OpenShift operators easily. Most of the functionality of a CSI Driver Operator is already available there. The {ibm-power-server-name} Block CSI Driver Operator is installed by the Cluster Storage Operator. The Cluster Storage Operator installs the {ibm-power-server-name} Block CSI Driver Operator if the platform type is Power Virtual Servers.

== Overview
|
|
|
|
{product-title} can provision persistent volumes (PVs) by using the Container Storage Interface (CSI) driver for {ibm-power-server-name} Block Storage.
|
|
|
|
Familiarity with xref:../../storage/understanding-persistent-storage.adoc#understanding-persistent-storage[persistent storage] and xref:../../storage/container_storage_interface/persistent-storage-csi.adoc#persistent-storage-csi[configuring CSI volumes] is helpful when working with a CSI Operator and driver.
|
|
|
|
To create CSI-provisioned PVs that mount to {ibm-power-server-name} Block storage assets, {product-title} installs the {ibm-power-server-name} Block CSI Driver Operator and the {ibm-power-server-name} Block CSI driver by default in the `openshift-cluster-csi-drivers` namespace.
|
|
|
|
* The _{ibm-power-server-name} Block CSI Driver Operator_ provides two storage classes named `ibm-powervs-tier1` (default), and `ibm-powervs-tier3` for different tiers that you can use to create persistent volume claims (PVCs). The {ibm-power-server-name} Block CSI Driver Operator supports dynamic volume provisioning by allowing storage volumes to be created on demand, eliminating the need for cluster administrators to pre-provision storage.
|
|
|
|
* The _{ibm-power-server-name} Block CSI driver_ allows you to create and mount {ibm-power-server-name} Block PVs.
