Changes

iSCSI (SCSI over TCP/IP) and AoE (ATA-over-ethernet) are different SAN protocols that can be used on a standard ethernet network. iSCSI did not work reliably in Fedora 12 on ARM systems, but will be needed by future ARM server systems. AoE has not been well-tested on ARM systems.  Goals of this project:(1) iSCSI and AoE need to be tested for stability and performance. (2) The ARM builders, which currently use loopback-mounted filessystems on top of NFS, and should be reconfigured to use iSCSI or AoE (whichever is the best optimal solution implemented on ) providing it is faster than the ARM build farmcurrent solution.
