 # Requirements and considerations for application volume group for SAP HANA 
@@ -43,6 +43,7 @@ This article describes the requirements and considerations you need to be aware
 * Application volume group supports Basic network features. If you're registered for extension 1, application volume group also supports [Standard network features](azure-netapp-files-network-topologies.md).
 * Extension 1 supports [availability zone volume placement](use-availability-zones.md) as the new default method for placement. This upgrade mitigates the need for AVset pinning and eliminates the need for proximity placement groups. With support for availability zone volume placement, you only need to select the same availability zone as the database servers. Using availability zone volume placement aligns with the Microsoft recommendation on how to deploy SAP HANA infrastructures to achieve best performance with high-availability, maximum flexibility, and simplified deployment. 
     If regions do not support availability zones, you can select a regional deployment or choose proximity placement groups.
+* Extension one supports [customer-managed-keys](configure-customer-managed-keys.md).
