AFAIK, there's no ATA-over-Ethernet support in FreeBSD, leaving iSCSI as the only "network block device" option. Although, I guess one could use ggate to export the remote disks. Not sure how that compares to iSCSI/AoE. Or where exactly in the storage stack that works (below iSCSI/AoE??). -- Freddie Cash fjwcash@gmail.com
