Note that this iSCSI approach is getting implemented as part of Colorado phase 1, which should hopefully be available on OpenSolaris in the 2009.06 time frame. See the iSCSI requirements and design: http://opensolaris.org/os/project/colorado/Requirements/iscsi-requirements-1.pdf http://www.opensolaris.org/os/project/colorado/Design/iscsi-design.pdf Thanks, Nick
