I'm guessing there's probably several such maiframes spread out all over the place. One would presumably not want to store all the world's money on one server.

I'm guessing there's probably several such maiframes spread out all over the place. One would presumably not want to store all the world's money on one server. At the very least banks all have their own, right? And would they not want redundancy? 1.5 million might stil be a bit low though.

> One would presumably not want to store all the world's money on one server. That's not how any of this works. Money is not stored anywhere in particular, unless we are talking about physical currency or commodities. The entire point of a mainframe is to be able to centralize critical things (like credit card processing) that simply cannot be allowed to fail. Most large banks and credit card processors operate their own pile of magic and then settle after the fact. It's not like VISA's IBM is the one big money bin that everything runs through. > 1.5 million might stil be a bit low though. In my scenario above, 1.5 million is a joke. That max spec machine could easily handle tens or hundreds of billions of credit card transactions in that timeframe.
