With SQL Server my preference would be to use AlwaysOn Availability Groups in SQL 2012 and avoid the need for shared disk failover clustering altogether. But technically the limitation is with vSphere at the moment. VMDK's can't be used for clustering across boxes, at the moment. I'm expecting that will be addressed by VMware in a future release.

You're welcome. Any thoughts on getting SQL Clustering on NFS support like Exchange?

Thanks Mike, appreciate the support.

I've been following Josh's movement and wish you all the best in making waves and getting this done. Is there a reason why SQL Server clustering isn't being addressed in the same way? It seems to me the same argument still applies.

Thanks and all the best,

Mike
