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.

  OG.
