While rack mount servers still use SCSI, that's about it, and a
bunch of our latest in our computer room have come with 2.5" SAS
drives (Serial Attached SCSI). All the new Sun Workstations look
to be using SATA, not sure about the IBM or HP's. My current Sun
is an aging SunBlade 1000, and it uses fibre drives.
I think both EIDE, and SCSI are slowly on their way out. Though
hopefully SCSI will stick around for a while longer.
Indeed, perhaps we're splitting hairs here, but I believe we could
easily consider both SAS and Fibre Channel to be SCSI. They are both
different low-level transport mechanisms for SCSI. The only possible
nit here is that Fibre Channel can also be used as the transport
mechanism for other high-level protocols like IP.
To say "SAS isn't SCSI" or "FC isn't SCSI", it wouldn't
be taking
things too much further to say "Differential SCSI isn't SCSI".
Most of the important benefits of SCSI are in the command set, not
the type of connectors and voltage levels in use.

Really. How many different kind of machines are
coming *brand
new* with SCSI *right now*?
Pretty much anything that isn't a desktop PC with a year or so of
design life, I would have thought. It's still perfectly alive and
well for people who care about quality.
