Well, Google is in a different situation. They can even request their own
modified motherboards and customize so they get exactly what they want. We
can not do that in the SME market.

What was looking very interesting was this Raptor server:
https://secure.raptorcs.com/content/TL2SV1/intro.html

However, the bigger POWER9 CPUs were not available at the time we were
looking at it - this has changed now.

Still I wasn't sure how to compare the real life speed of POWER9 compared
to something like the AMD EPYC 7601. And then, will everything work smooth
on POWER the same way it does on the AMD? POWER seems still not a first
preference arch for CentOS, so how would it impact us? Is it smart to add
another CPU arch if we still have to run some X86 code, like in our case
SAP MaxDB (which is also available for AIX on POWER but not Linux on
POWER)?

In the end we decided for AMD EPYC but kept the POWER thing in mind. Now
that IBM announces the purchase of RedHat it just reminded me that this
could become interesting again in the future. Let's see how it goes.

Simon
