If you would like to have two AoE initiators running md, with AoE
targets as the md components, then I think you will need an
active/passive setup instead of an active/active setup, because md is
not "cluster aware."

However, most of the problems I can think of with using md on two
initiators at the same time over a common set of AoE targets have to
do with failing individual components, or with the consistency of the
state of the RAID itself, and these issues go away with a RAID 0,
since it's not redundant and immediately fails when one component
fails.

So I think that if you forget about most of your scenario and only ask
in a Linux Software RAID forum about the feasibility of having two
hosts trying to do RAID 0 over the same AoE targets at the same time,
you might get an answer.  You'll probably also get a lot of confused
looks, too.

Good luck!
