Hi
Thanks for your feedback.
In the company we are working for we are looking at buying a p520 system with HACMP, that it why I am looking for a ppc version.
I'd run AIX on that. PowerHA (formerly known as HACMP) is still primarily an AIX cluster, with only limited linux support. the extent of that support is detailed here, http://www-01.ibm.com/common/ssi/cgi-bin/ssialias?infotype=dd&subtype=sm... says specifically, RHEL4 or SuSE LES 9.
Full PowerHA for AIX features -> http://www-03.ibm.com/systems/power/software/availability/aix/faq/index.html
I would also involve IBM as much as possible in the setup and configuration of any such cluster, unless you have a large amount of time to waste trying to sort out all the pieces.
