The Azure VMware Solution (AVS) resource needs to be deployed in the same region as the Everpure Cloud Azure Native Service. For reliability and best performance results, it is required to also use the same Availability Zone (AZ) and the same Azure Subscription.
Ensure that your AVS resource is located in one of the supported regions and that all hosts are deployed within a single availability zone. Configurations with AVS hosts spread across multiple availability zones currently do not support any external storage.
Connection between AVS and the VNet of the service will utilize the ExpressRoute Circuit that is deployed alongside the AVS cluster.
Setup and Check connectivity between Azure VMware Solution and the VNet
It is recommended to ensure the connectivity (ExpressRoute circuit) between Azure VMware Solution and the VNet designated for PSC Azure Native service is configured properly.
Select the ErGw3Az SKU for the Express Route VPN Gateway, and then during the connection creation, make sure to enable FastPath feature. Without this SKU selected and FastPath feature enabled, performance is strongly degraded. Instructions on how to deploy the virtual network gateway, enable FastPath, and establish connectivity are covered here.
A method to validate the connectivity between a VNet and an AVS cluster is described here: Microsoft LearnConfigure External Storage Address Block
Ensure that the External Storage Address Block feature is enabled and configured on the AVS resource. This feature adds VMkernel ports to the existing AVS ESXi hosts and improves data path for external storage.
-
Within the AVS resource, go to the Manage tab and click on Storage.
-
Select the External Storage Address Block tab.
-
Follow the displayed guidance on address block CIDR range.
-
Enter the selected CIDR range into the Address block to deploy external storage field.

Click the Save button.
