How may spares do you carry?

If you want to do scheduled hardware mainennance that's one thing. Doing 
hardware mainennance because something broke during software maintenance 
is something entirely different.

If I schedule a reboot at 18:00 when hardly anyone's around, and the 
system fails because the hardware's suddenly broken, we're in trouble.
