Although this chapter is long, it is still only the tip of the iceberg when it comes to knowing everything the DBA should know about SQL Server 2005 clustering. In addition to reading this chapter, you should read all of the clustering articles in the SQL Server 2005 Books Online, and any additional information you can find on Microsoft's Web site and the Internet. As we said at the beginning of this chapter, clustering is an adventure, and after reading this chapter, we are sure you now agree.
