Add additional SQL instance to existing SQL Server 2008 R2 Cluster

This post will be focused on how to add additional SQL instance to an existing SQL Server 2008 R2 Cluster. At first I was a little confused about the concept of Active/Active and Active/Passive and its relationship with SQL failover clustering. In a multi failover cluster instances, these terms can be seen as ambiguous when used to describe the configuration of the SQL Server instances and the nodes they are running on.
