Yeah x86_64 is the chosen platform.

I thought 24 cores was the limit for xSeries. How far can you go..?

I heard that the architecture of the high and IBM xSeries is NUMA based (rather than SMP) and I was concerned at whether an Oracle database with a large SGA would be able to scale on a NUMA based box considering the relatively high latencies of non-local memory access.

Do you have any experience with Oracle on high end xSeries..?
