For iscsi in linux you can use network bonding or dm-multipath or maybe 
even both :) For example, you can use bonding on the initiator over 
multiple host NICs, and use dm-multipath to multpath over multiple 
target portals.

Not exactly sure what you mean by this. Are you thinking about RDAC as 
in Engenio's RDAC where we might need to do some sort of manual failover?
