redunduncy of SCSI controllers possible?

[Carlos Carvalho]

All this talk about raid reminded me of a rarely discussed topic.
Suppose you split a raid array in more than one controller, as is
usual for speed reasons, and there's more than one disk on a given
controller. This controller is a single point of failure, since if it
fails the raid is gone.

Is it possible to put two controllers on the same bus, and if one of
them fails the other keeps with all disks?
