I've been doing a lot of reading on clustering and would just like someone to confirm that I'm understanding all this correctly. The company I work for have a database application and also want to implement MS Sharepoint. Am I right in saying that I can have three nodes: one with a SQL instance to run the db app. one with a SQL instance to run sharepoint. And finally, a third node to act as failover for both of these apps, effectivly giving me an N+1 configuration? Thanks in advance for any help.
