Hi folks,
after reading several articles about Mainframes and similar archs
(even ancient ones like B7000), I wonder if Linux world could
learn something from there.
One very interesting point (IMHO) is the storage abstraction.
AFAIK, Mainframes work on one large virtual memory (disks for
swapping out RAM, tapes for swapping out disks, etc).
This way you just allocate some piece of space (like some virtual
partition) to an application (of guest). If you need more space,
just plug in more disks and the OS will handle all this automatically.
I'm currently planning to implement an similar approach for Linux
(at least virtual block devices).
What do you think about this ?

Check out LVM (Logical Volume Manager)

Seems to do exactly what you're talking about.
