Is your actual server a SMP 332 MHz or uniprocessor wide node ? (I'll
consider it is the uniprocessor node because I'm not too sure about the
minimum AIX level for the SMP Node).

SP transfer speed is a good point if you have a switched frame.

I don't know what brought Henk to this decision, but if the problem is
scalability, there are some SP newer nodes with bigger throughput, like a
the S70/A external node or internal SMP Wide nodes. And a new PCI High Node
is to be announced.

The F50 has the same architecture than the SMP 332 MHz Wide Node, so it is
almost 100% correct to say that it can handle whatever the F50 can handle (
very few exceptions).

However, if you have to move the server out of the SP, take I/O capacity
into bigger consideration. The H70 has a more powerful I/O architecture.
