Hi Sascha:
Considering a PC partitioning scheme on a PPC system defeats
the
purpose of why you are using a PPC system in the first
place. Leave
that stuff for Intel based architectures.
Technically arguments can go one way or another, but
sometimes these
nuances between architectures matter in getting things done
and in
examining why some attempts or "work arounds" may
just not be worth it.
So just master the PPC stuff you need, keep your PC
experience in the
background and if there are relationships or points of
similarity from
an engineering standpoint then note that. However, one to
one
correspondence, ie. what technical methods worked in one
system may not
work optimally with another. If you think Apple's stuff is
hairy, you
may have missed the technical documents IBM provides
regarding similar
setups for their RS/6000 using AIX. Not that material is
real
engineering!
No one I've met would try to apply badmington rules in
baseball, and
likewise it is between PC/Intel engineering schemes and PPC
engineering
schemes. The difference between the architectures and how
they access
peripherals could fill books; that's another story.
Onto something a bit more useful to you. TSS does provide
this
information regarding RAID setup in the ydl.net service.
