Forget a good portion of everything you know about deploying failover clustering if you're used to Windows Server 2003 and SQL Server 2000 or 2005. With the introduction of Windows Server 2008 and with further improvements in R2, Windows failover clustering is a different experience than in the past. Come to see how the changes and improvements to Windows affect clustered SQL Server deployments. There are quite a few things that can trip you up in the areas of setup, upgrade, and patching processes (among other things) with SQL Server 2008 with its changes. This session bridges the gap of what you may have known to what you now need to know to have successful deployments of SQL Server 2008 failover clustering on Windows Server 2008 R2.
