SQL 2014 CSV on iSCSI StoreVirtual SAN

Hello

I have read a lot about Cluster Shared Volumes benefits with SQL 2014 and I am trying to determine if my environment would be a good candidate for using them.   Most literature seems to be based around storage spaces and jbod type storage and I can obviously see the benefit there.  However I cannot find many discussions of people using CSV with traditional iSCSI SAN such as HP StoreVirtual.  Besides faster failover, simplicity of management etc what would be the benefit there?  What would the "gotcha's" be?

Is anyone using CSV with iSCSI storage?

Thanks

Phil
