a. HPs SAS drives don't have the same form-factor as the SATA drives, or,
at least, not the SATA drives I've had experience with, so although the
interface may work with either, the rack mount servers don't have that
option ... my love of the SAS drives is 4 drives per 1U rack, which
means I can do RAID1+0 instead of RAID5 on SCSI/SATA racks ...
b. are ppl actually using/promoting SATA drives in a server environment?
Or are we just talking about situations where you have a large number
of spindles to work with? My one experience with an SATA configuration
is that the server doesn't *feel* like its performing as well as my
SCSI servers do ... under load ...
