Well there are reasons why mainframes and mini's like these don't ever reboot -
one is the software they load on it... I mean just how complicated can a cobol
program be to crash a mainframe?
Also, the design and architecture of these buggers makes for a really secure
and protected environment in such a way that a wayward pointer won't be able to
stumble upon some kernel address table and nuke the system.
Next, there's the quality of the hardware. In my knowledge, the one factor
that will keep a server running on and on and one for years is how good the
hardware it is run on. I mean, even on normal PC servers, just giving them
kingston memory increases your system stability several=fold..
