Introduced in Microsoft SQL Server 2012. AlwaysOn Availability Groups maximizes the availability of a set of user databases for an enterprise. Deploying AlwaysOn Availability Groups involves creating and configuring one or more availability groups. Each availability group is a container for a discrete set of user databases, known as availability databases, that fail over together. An availability group can have multiple possible failover targets (secondary replicas). Moreover, you can configure secondary replicas to support read-only access to secondary databases and for performing backups on secondary databases.   High Availability (Windows Cluster) + Disaster Recovery (Mirroring) Primary + 4 secondaries 1 automatic failover pair 2 synchronous 2 asynchronous Can place multiple nodes & databases in Availability Groups Can do backup and reporting off secondaries Availability Groups support Virtual names Built in compression and encryption Windows Server Core supported Multi-site clustering across subnets Support for network attached storage   en Fri, 24 May 2013 17:22:44 GMT Fri, 24 May 2013 17:22:44 GMT Rev9 Re: SQLShorts : AlwaysOn SQL 2012 Volume is too low to understand...pls fix it...
