The cluster for DAG1 is created when EX1 is added to the DAG. The commands to create a DAG without a cluster administrative access point are very similar: New-DatabaseAvailabilityGroup -Name DAG1 -WitnessServer EX4 -DatabaseAvailabilityGroupIPAddresses ()::None New-DatabaseAvailabilityGroup -Name DAG1 -WitnessServer EX4 -DatabaseAvailabilityGroupIPAddresses 10.0.0.5,192.168.0.5ДЄdd-DatabaseAvailabilityGroupServer -Identity DAG1 -MailboxServer EX1ДЄdd-DatabaseAvailabilityGroupServer -Identity DAG1 -MailboxServer EX2ДЄdd-DatabaseAvailabilityGroupServer -Identity DAG1 -MailboxServer EX3 Two servers (EX1 and EX2) are on the same subnet (10.0.0.0), and the third server (EX3) is on a different subnet (192.168.0.0).

This example shows you how to use the Exchange Management Shell to create a DAG with a cluster administrative access point that will have three servers.

It must be managed using Windows PowerShell, and the PowerShell cmdlets must be run against individual cluster members. The cluster cannot be managed using the Failover Cluster Management tool. The name of the cluster/DAG is not registered in DNS, and it is not resolvable on the network.ДЄ cluster name object (CNO) is not created in Active Directory. There is no network name assigned to the cluster, and therefore no Network Name Resource in the cluster core resource group There is no IP address assigned to the cluster/DAG, and therefore no IP Address Resource in the cluster core resource group.

DAGs without cluster administrative access points have the following characteristics: DAGs without an administrative access point can be created only on servers running Exchange 2019, Exchange 2016, or Exchange 2013 Service Pack 1 or later, with Windows Server 2012 R2 Standard or Datacenter edition. The failover cluster heartbeat mechanism and cluster database are then used to track and manage information about the DAG that can change quickly, such as database mount status, replication status, and last mounted location.Дuring creation, the DAG is given a unique name, and either assigned one or more static IP addresses or configured to use Dynamic Host Configuration Protocol (DHCP), or created without a cluster administrative access point. In addition to a failover cluster being created, the infrastructure that monitors the servers for network or server failures is initiated. Use of the cluster for any other purpose isn't supported.

This failover cluster is used exclusively by the DAG, and the cluster must be dedicated to the DAG. When you add the first server to a DAG, a failover cluster is automatically created for the DAG.

This directory object is used to store relevant information about the DAG, such as server membership information and some DAG configuration settings. A DAG is initially created as an empty object in Active Directory. As with all Exchange high availability configurations, you must ensure that all Mailbox servers in the DAG are sized appropriately to handle the necessary workload during scheduled and unscheduled outages.ДЄ DAG is created by using the New-DatabaseAvailabilityGroup cmdlet. It's supported to create a DAG that contains a combination of physical Mailbox servers and virtualized Mailbox servers, provided that the servers and solution comply with the Exchange Server system requirements and the requirements set forth in Exchange Server virtualization.
