One very common scenario was/is RAID volumes provided by a SAN from 
various underlying parity groups - a stripe only over these was/is very 
common to see. Also, one of the common use cases for a concatenation - as 
opposed to a stripe - was multiple LUNs being provided from the same 
parity group.

Sites still hammering their big array investment from 10 years ago is 
common. That brand new Illumos host might just be getting some storage 
from such an old array.
