Watch the RAID type you use. Unfortunately many vendors know about SANs, but not about SQL. Unless your application is appropriate, you don't want to end up with RAID 5 everywhere, but this appears to be the default for most suppliers, and consequently SANs get a bad rep.

Costs are high, but they are also good, if done well. They make especially good sense for clusters, and can offer good cost savings over multiple clusters compared to lots of DAS units.
