Is it possible to imagine a server that has access to a sufficiently
large area of disk, so that really LRU windows get dumped there?

Didn't we used to call disk "backing store"?

Of course, this runs contrary to the trend, but it's surely one way of
making a server with a reasonably sized backing-store available in a
highly-specified environment.
