Just curious, but in your "ideal" situation, is it considered best
to use 1 controller for each vdev or user a different controler for
each device in the vdev (i'd guess the latter but ive been wrong
before)
From both a fault-tolerance standpoint, and performance standpoint, it
is best to distribute the vdev devices across controllers. With
perfect distribution, you could pull a controller and it would be as
if one drive failed in each vdev (and you can still read your data).
If a controller messes up and sends bad data, then the damage is more
limited.
