"While the thousand PC's described above are almost certainly overkill for 40,000 typical websites, I chose that high number for a reason; the cost of a fully-configured S/390 is roughly that of a thousand inexpensive Intel systems. That is the price/performance standard that the mainframe would have to meet to be cost-effective in this large, but simple, example scenario."
"(Note that this is not a practical configuration; for the workload described above, one or two hundred PC servers would be adequate and would cost a fraction of the price of a single mainframe. To handle the load comparably, of course, several mainframes would be necessary.)"
"More realistically, if your shop has an S/390 with some excess capacity, you can use it now rather than letting it sit idle. Then, as your OS/390 workload grows, you can migrate the Linux workload to another system. Due to the large increments in which mainframe capacity is purchased, and because systems must be configured for the rare, peak loads, most mainframe shops have a lot of free processor cycles. That unused capacity, along with the fact that nearly any Internet service can run happily under Linux, produces a scenario where the Blue Suit and the Tux go well together."
