Paul, Yes, the bus structures are similar and in the x M2 variants faster. I just attempted to lay my hands on a the technical paper I read about this to no avail and I'm struggling to recreate the search I used to find it originally. When I went after that is was my intent to confirm that the overall bus structures were indeed similar and that is what I found.
I'll try to find that document again and post it when I do. Thanks, Kelly Lipp Chief Technical Officer www.storserver.com 719-266-8777 x7105 STORServer solves your data backup challenges.

I'm curious - does your analysis include the number of busses available? I know that the pSeries has quite a lot of busses to drive all of its adapters. I'm not as familiar with the xSeries, so I don't know if there is a model available that has a comparable number of busses. It's not just the speed, it's the overall throughput that most concerns me. Sure, I could have more smaller xSeries servers, but then I would have more resource baskets to manage.
