If I had virtualized my storage to make it uber-HA, like two EMC or IBM arrays behind a VPLEX (local) or SVC appliance so that even if one of the arrays quit serving storage my clients would not notice...

Would I prefer to use SQL Server 2012 they way I had in the past, or use the AlwaysOn availability groups and connect directly to each of the storage arrays (not use the VPLEX or SVC)?

Kind of a question between using the native functionality in SQL 2012 versus licensing storage space on a virtualization appliance.
