Introduction
Stretched clusters with Dell EMC Solutions for Azure Stack HCI can be configured using PowerShell. This guide describes the
prerequisites for this deployment.
NOTE: The instructions in this guide are applicable only to the Microsoft Windows Azure Stack HCI operating system.
Each task in this deployment guide requires running one or more PowerShell commands. On some occasions you might have to
use Failover Cluster Manager or Windows Admin Center from a machine that supports Desktop Experience.
Deployment prerequisites for stretched clusters
Dell Technologies assumes that the management services required for the operating system deployment and cluster
configuration are present in the existing infrastructure. An internet connection is required to license and register the cluster
with Azure. Because Microsoft Azure Stack HCI operating system is a Server Core operating system, you require a system that
supports Desktop Experience to access Failover Cluster Manager and Windows Admin Center. For more information, see the
Windows Admin Center FAQ.
