Go the P550 route. I've seen P-series boxes handle 3 to 5 times the
amount of workload an Intel box can handle, and I'm a big fan of Linux.
I know more about Linux than I do AIX. However, you need the right tool
for the job, and the P-series box will do the job, and do it longer.
On heavy I/O boxes I'm convinced that P-series is the way to go.
Especially if you can get the AIX box for the same price as the x86 box.
However, if not you'll need more than one x86 box to handle the load.
