Dell Technologies assumes that the management services that are required for the operating system deployment and cluster configuration are in the existing infrastructure where the Azure Stack HCI cluster is being deployed.
The following table describes the management services:
| Management service | Purpose | Required/optional |
| Active Directory | User authentication | Required |
| Domain Name System | Name resolution | Required |
| Windows Software Update Service (WSUS) | Local source for Windows updates | Optional |
| DHCP | Hosts get IPs before and after host configuration via Network ATC | Optional |
| OS-iDRAC passthrough IPs should be different for each node | To avoid IP-conflict with the cluster | Required |
