Correct.  That is what the RAID1/0 is on MF.  On MF four mirrored logical volumes (8 drives) are put together on the front end and presented as one.  If you created a 4 way striped meta on top of 4 mirrored FBA devices, you would have the same thing.
In one tech book it clearly indicated that RAID 1/0  is for mainframe use only in Symmtrix. But someone from EMC is telling us that Raid 1/0 can be used for any open systems including MS Windows. We are going to use VMAX for Window/MS Sql server.
Raid 1/0 for window host?
