I am trying to learn how the failover clustering features works with Windows 2008 R2 as I am going to be using as part of SQL Server 2012 always on.
I have been able to find information on how to set it up, and what it does. However, I am having trouble finding a nice technical document on how it actually works in detail (For example with keepalived there are docs that explain how often are heartbeat packets sent, what they look like etc).
I know this is a pretty broad question, but I would like to have a good understanding of mechanisms of this feature.
