I think he was looking for Power vs x86 in price/performance.
I.E If you spend 50K on Power systems and 50K on x86 systems. which
could produce more I/O throughput.
(If not, that's what I'd like to hear an update on)
>From what I remember from previous discussions, x86/linux would come out
on top for pure price/performance,
but managing many x86 systems vs a single/fewer Power systems certainly
has some value.
I'm sure there are many other intangibles when it comes to value.

Shawn

Re: [ADSM-L] Check signals on Power vs. x86...
Yes, it is. There are very few things I would say this about, but this is
one of 'em.
For a RHEL box to match the performance capabilities it would have to be
installed on Power as well (which it can be). I think the evidence I've
seen both in experience and raw numbers has shown the power boxes can
sustain higher levels of throughput and performance. Because to get an
x86 box to perform at those levels you would have to spend just as much,
buying one really powerful x86 box, or spreading it across multiple boxes.
All that said, if we didn't have a good AIX guy here, I'd go RHEL on
multiple boxes, or on a really powerful x86 box. I can admin AIX, but I'm
much more comfortable on Linux. So, as someone else said, it all depends
on what you're good at.

I'm looking around for an update on my expectations that power hardware
and AIX is more performant per memory/CPU/IO than x86 and RHEL.
I know this topic comes up from time to time; I don't think I've seen it
rehashed particularly recently.
I'm an advocate of AIX for this, but I wanted to check signals and
experiences, again.
