Strange, isn’t it – IBM Corp has a board that packs six 9221 microprocessors, creating a six-way tightly-coupled multiprocessor on a single board, and showed it as one of the building block of its so-called parallel High Performance Database Server – but if it really works, and IBM is really committed to crashing the price of mainframes, why hasn’t it launched the thing as a top-end compact 9221? The answer is presumably that there are still a few people out there prepared to pay a much higher price for the 9121 model it would compete with – at which point people start to wonder whether it is really committed to cutting mainframe tags – either that or even the single board building block doesn’t actually work the way it should yet.
