+= Creating a storage class with storage account type
+
+
+Storage classes are used to differentiate and delineate storage levels and usages. By defining a storage class, you can obtain dynamically provisioned persistent volumes.
+
+When creating a storage class, you can designate the storage account type. This corresponds to your Azure storage account SKU tier. Valid options are `Standard_LRS`, `Premium_LRS`, `StandardSSD_LRS`, `UltraSSD_LRS`, `Premium_ZRS`, `StandardSSD_ZRS`, and `PremiumV2_LRS`. For information about finding your Azure SKU tier, see link:https://learn.microsoft.com/en-us/rest/api/storagerp/srp_sku_types[SKU Types].
+
+.Prerequisites
+
+* Access to an {product-title} cluster with administrator rights 
+
+.Procedure
+
+Use the following steps to create a storage class with a storage account type.
+
+. Create a storage class designating the storage account type using a YAML file similar to the following:
++
+[source, terminal]
+--
+$ oc create -f - << EOF
+apiVersion: storage.k8s.io/v1
+kind: StorageClass
+metadata:
+  name: <storage-class> <1>
+provisioner: disk.csi.azure.com
+parameters:
+  skuName: <storage-class-account-type> <2>
+reclaimPolicy: Delete
+volumeBindingMode: WaitForFirstConsumer
+allowVolumeExpansion: true
+EOF
+--
+<1> Storage class name.
+<2> Storage account type. This corresponds to your Azure storage account SKU tier:`Standard_LRS`, `Premium_LRS`, `StandardSSD_LRS`, `UltraSSD_LRS`, `Premium_ZRS`, `StandardSSD_ZRS`, `PremiumV2_LRS`.
+
+. Ensure that the storage class was created by listing the storage classes:
++
+[source,terminal]
+--
+$ oc get storageclass
+--
++
+[source,terminal]
+.Example output
+--
+$ oc get storageclass

+managed-csi (default)   disk.csi.azure.com   Delete          WaitForFirstConsumer   true                   68m
