I wrote a piece on using Dell's Management Suite Infrastructure for vSphere. Hardware Inventory and Storage information is included in the vSphere Client plugin that may give you some information you're seeking.

But this is just pulling the information from Dell's out-of-band management interface, iDRAC. You could simply use this interface to view and manage your RAID controllers and RAID configurations.
All the best,
Mike
