Call me a sysadmin, but I find easier to plug in and keep in place an ethernet cable than these parallel scsi cables from hell. Every server has at least two ethernet ports by default, with rarely any surprises at the kernel level. Adding ethernet cards is inexpensive, and you pretty much never hear of compatibility problems between cards. So ethernet as a connection medium is really nice compared to scsi. Too bad iscsi is demented and ATAoE/NBD inexistant. Maybe external SAS will be nice, but I don't see it getting to the level of universality of ethernet any time soon. And it won't get the same amount of user-level compatibility testing in any case.
