forget those cheap UPS....
get a car battery.... run it off a car battery charger...
convert all your powersupply frm 110Vac to +12v input power supply
and now you can run for 12hrs without any 110Vac...
one car battery lasts about 12hrs for one server...
and yeah... if you using normal consoles... its a little trickier to put
the login on each tty.... X11 does make some things easier...
