Get a fast start to
using AlwaysOn , the SQL Server solution to high-availability and
disaster recovery. Read this short, 150-page book that is adapted from Peter
Carter's Pro SQL Server Administration to gain a solid and accurate
understanding of how to implement systems requiring consistent and continuous
uptime.
Begin with an
introduction to high-availability and disaster recovery concepts such as
Recovery Point Objectives (RPOs), Recovery Time Objectives (RTO), availability
levels, and the cost of downtime. Then move into detailed coverage of
implementing and configuring the AlwaysOn feature set in order to meet the
business objectives set by your organization.
SQL Server AlwaysOn Revealed offers real-world advice on how to build and
configure the most appropriate topology to meet the high-availability and
disaster recovery requirements you are faced with. Content includes strong
coverage on implementing clusters, on building AlwaysOn failover clustered
instances, and on configuring AlwaysOn Availability Groups. This is a practical
and hand-on book to get you started quickly in using one of the most talked-about
SQL Server feature sets.
Teaches you to build HA and
DR solutions using the AlwaysOn feature set

Chapter 3: Implementing a Cluster Implement and configure a Windows failover cluster using Windows Server 2012 R2. The cluster will form the base to support either an AlwaysOn Failover Clustered Instance or AlwaysOn Availability Groups.
Building the Cluster
Configuring the Cluster
Chapter 4: Implementing an AlwaysOn Failover Clustered Instance Learn the differences between building a stand-alone instance and building an AlwaysOn Failover Clustered Instance. Also learn to add a node to an existing AlwaysOn Failover Clustered Instance.
