Changes

iSCSI (SCSI over TCP/IP) and AoE (ATA-over-ethernet) are different SAN protocols that can use be built on top of a standard ethernet network. iSCSI did not work reliably in Fedora 12, but will be needed by future ARM server systems. AoE has not been well-tested on ARM systems. iSCSI and AoE need to be tested for stability and performance, and the best solution implemented on the ARM build farm.
