Database availability groups (DAGs) are discussed as an important redundancy for Exchange Server mailbox databases during this Exchange Admin Center (EAC) demonstration.
- [Instructor] Do you know what fire, road construction,…hard drive failure, and Microsoft updates…all have in common?…They can all take your Exchange Server offline…for hours or days at a time.…Since that kind of outage is not acceptable,…Microsoft has built a clustering feature…into Exchange Server 2016.…Database Availability Groups, or DAGs, are available…in Exchange Server 2013 and 2016.…It allows you to cluster up to 16 exchange servers…so that you can live through hardware failure,…server failure, and network failure.…
It's reasonable to point out that many server…operating systems and network environments…have fault tolerance features designed to minimize…downtime for entire servers, but most of those…don't work the same for database applications.…Microsoft built DAGs into the design…of Exchange Server specifically to cluster…the mailbox database, and you can place replicas…of the database on up to 16 servers and these servers…can be placed near each other to prevent an outage…stemming from hardware failure or just being offline…
