This step by step guide will take you through the process of installing an Exchange Server 2010 Database Availability Group. Exchange Server 2. Database Availability Group Installation. Microsoft Exchange Server 2. Database Availability Group DAG. This tutorial describes how Database Availability Groups work in Exchange Server 2. DAG using Exchange Server 2. SP1 and Windows Server 2. R2. Exchange Server 2.

A Database Availability Group is a group of up to 1. Exchange Server 2. Mailbox server role. Each server that is a member of the DAG is capable of hosting active or passive copies of mailbox databases that reside on servers in the group. For example, a Database Availability Group may consist of three Exchange Server 2. Mailbox servers, each configured with a single Mailbox database. Each server that is a member of the DAG can host either an active or passive copy of each of the three total mailbox databases. Exchange Server 2. Database Availability Group Example. The foundation of an Exchange Server 2. Database Availability Group is Windows Failover Clustering. However unlike traditional Exchange server clusters which existed in an activepassive state, and in which the entire cluster group needed to failover to an alternative node together, with Exchange 2.

This means that any given Mailbox server in the DAG can host all, some or none of the active mailbox copies at any given time. This capability provides two immediate advantages over previous clustering models All of the Mailbox servers within the Exchange 2. DAG can be active and in use at all times to some capacity. Each mailbox database can failoverswitchover when necessary without impacting the mailbox users connected to other mailbox databases within the DAG, for example when installing updates on DAG members.

UpdateStar has been tested to meet all of the technical requirements to be compatible with Windows 10, 8. Windows 8. Understanding Quorum for Exchange Server 2. Database Availability Groups. Because the Database Availability Group utilizes an underlying Windows Failover Cluster the concept of quorum applies. If you are not familiar with quorum consider it as basically a voting process in which a majority of voting members must be present to make a decision. For a cluster this means that an odd number of members must be involved in the voting process for a majority decision to be made. How this applies to an Exchange Server 2. DAG is that if you deploy a DAG with just two Mailbox servers as members or any even number up to 1. To achieve quorum for a DAG with an even number of member servers another server in the same site is designated as a File Share Witness for the cluster. This is typically a Hub Transport server though it can technically be any compatible Windows server. Database Replication in Exchange Server 2. Database Availability Groups. There are two ways that mailbox database replication occurs between Exchange Server 2. DAG members. In Exchange Server 2. RTM file mode replication is used. With file mode replication as each transaction log is written and then closed off once it reaches 1. Mb in size it is then copied to each member of the DAG that also holds a copy of that mailbox database. The other members receive the file into their replay queue, and then replay the transaction log file into their own passive copy of the database. File mode replication works fine but has an obvious shortcoming in that any transaction logs that have not yet been shipped to other servers in the DAG can be lost if the Exchange server hosting the active database copy fails. In those cases one of the other DAG members is able to bring their copy of the mailbox database online and then request missing emails be resent from the transport dumpster of Hub Transport servers within the site.

SP1 file mode replication is used to bring mailbox database copies into sync with each other eg during the initial sync process when a new database copy is added. Once they are in sync the DAG members switch to block mode replication. In block mode replication each database transaction is written to the log buffer on the active server and also sent to the log buffer of DAG members hosting passive copies of the database. When the log buffer becomes full each DAG member then builds their own transaction log files from their own log buffer. Block mode replication has an advantage over file mode replication in failure scenarios, because each DAG member is completely up to date with all changes to the active database. Note that Public Folder databases can reside on Mailbox servers that are members of a Database Availability Group, however they are not replicated by the DAG itself. Instead you must use Public Folder replication to provide redundant copies of Public Folder databases. Other Advantages of Exchange Server 2. Database Availability Groups. Before we proceed with an example of how to install an Exchange Server 2. DAG I will also mention some of the other advantages of Database Availability Groups. Unlike previous versions of Exchange Server particularly Exchange Server 2. Exchange Server 2. Mailbox servers for all high availability deployment scenarios. When you create a Database Availability Group the underlying Windows Failover Cluster is automatically created and configured for you. A Database Availability Group can be created at any time without requiring Exchange Server 2. Exchange was installed. Exchange Server 2. DAG members can host other server roles, unlike Exchange Server 2. Mailbox servers from hosting other roles. Exchange Server 2. Installation Step by Step. In this tutorial I will demonstrate the installation of an Exchange Server 2. Database Availability Group on Windows Server 2. R2. For this tutorial the following Exchange servers have already been installed. EX1 Exchange Server 2. SP1 Mailbox server. Primary interface 1. Secondary interface 1. EX2 Exchange Server 2. SP1 Mailbox server. Primary interface 1. Secondary interface 1. Roman Polanski Interviews Pdf. EX3 Exchange Server 2. SP1 Client Access and Hub Transport server. Primary interface 1. Note for details of how to deploy these server roles see Installing Exchange Server 2. Pre requisites on Windows Server 2. R2 and Installing Exchange Server 2. Exchange Server 2. DAG Tutorial Setup. Each of the Mailbox servers has been configured with its own mailbox database. EX1 Mailbox Database 0. EX2 Mailbox Database 0. Note in Exchange Server 2. Because the Mailbox servers are configured with dual interfaces it is important to make sure that the secondary interface is not configured to register itself in DNS. Open the TCPIPv. Advanced button, navigate to the DNS tab and untick Register this connections address in DNS. Open the Advanced TCPIPv. Properties. Disable DNS registration for the secondary interface. Creating the Database Availability Group. Log in to one of the Mailbox servers and launch the Exchange Management Console. Navigate to Organization ConfigMailbox and choose New Database Availability Group from the action pane. Create a new Exchange Server 2. Database Availability Group. When the New Database Availability Group wizard starts give the DAG a name, specify the Witness server, and also specify the file path for the Witness server to use. New Database Availability Group Wizard Basic Info. Click on the New button to create the new Database Availability Group, and then click Finish to close the wizard.
