Based upon this statement
Microsoft SQL Server 2005 Standard Edition (32-bit or 64-bit)
Microsoft SQL Server 2005 Standard Edition supports up to two nodes in a failover cluster.
If I have an Win 2003 Active Passive cluster for SQl Server 2005 Std Edition. I can have two active instances on Physical Server A which could fail over to Physical Server B. Or is the reference to 2 nodes means I get an active instance and the other (2nd) instance is the failover?
