The rationale is that if you're doing zoning one bad rule pushed can take
down the entire fabric. By keeping the switches separate you're essentially
connected to two fabrics, so one going down isn't going to lose your
connectivity.
I've got a similar set-up. If you're going to do zoning it's highly
recommended that you split the fabrics just to keep you from shooting
yourself in the foot.
Cisco, BTW, is now an emerging player in the FC market (I recently bought
several switches at a fraction of what it would cost from Brocade), and
they'll make the same recommendations. FC is *not* ethernet. You can't
manage them the same way.
