i testet AoE and iSCSI. AoE scales very bad! If you have more than 10 AoE 
devices over one NIC you get on one AoE device bad througput and a high load 
on the system. iSCSI with lots (testet with over 200) of LUNs will performe 
very good. I was able to get a little more than 100MByte/s over one 1GBit/s 
NIC with iSCSI!
