Windows Storage Server 2008 (WSS 2008) with the Microsoft iSCSI Software Target 3.2 is now available to all MSDN and TechNet Plus subscribers. A version for evaluation (TechNet Plus or MSDN), demonstration (MSDN), development (MSDN) or test (MSDN) is now being provided to MSDN and TechNet Plus subscribers for the first time. Rather than using expensive shared storage you simply run Storage Server on another machine. All communication is done over regular Ethernet cables, so HBAs or an expensive SAN are not needed. With just any three computers (2 cluster nodes and 1 iSCSI Target / DC) and a hub you can have your own Failover Cluster! Now there are no excuses for not trying out clustering.
