I'm not sure I'd call that intelligent.
If the compatability goes far enough that either kind of device works
with either kind of interface, then I agree, but then there's really no
difference between them - they're just two names for the same thing.
If the compatability doesn't go that far, then we now have a way you
can plug something in that looks perfectly compatible but which does
not actually work when connected. I have trouble seeing how this is
good for anyone, this time including hardware makers.
The Dell server I've seen lately all have SAS backplanes but for a test
setup I swapped the SAS disks in some for SATA disks. Works perfectly
fine, it is just slower (the SAS disks are 15k6 RPM, the SATA ones 7k2
RPM).
Kind regards,
Alex.
