Yes, interesting read. I have some questions though.
1) Is CPU redundancy limited to the MCM, or does it work across books as well? If the latter is true, it seems to me that there's no software reason why the MCM could not be hot-swapped. So either they don't need this feature (surely the MTBF is extremely high) or there are hardware reasons not to support it. Could it be too difficult to make such a swap electrically safe?
2) Are the I/O processors included as specialized 'cores' on the same die as the CPU, as chips on the MCM, or as separate devices entirely?
