If I interpret your ascii gfx right, you want two big stripes and then
mirror them.. problem is if one disk from each mirror dies -> you lose..
Another way is to create 8 mirrors and stripe them..
zpool create blah \
mirror c2t40d0 c4t40d0 \
mirror c2t40d1 c4t40d1 \
mirror c2t40d2 c4t40d2 \
mirror c2t40d3 c2t40d3 \
mirror c3t40d0 c5t40d0 \
mirror c3t40d1 c5t40d1 \
mirror c3t40d2 c5t40d2
