We are a 3k shop, tried and true. However, we do use NT and I
thought I'd share a recent powerfail experience.

hp3k systems: 917 & 937 both with built-in battery backup.
   nt system: p-100 with UPS (20min. battery from APC) connected
                         to serial port for control
The chronology
--------------
all power goes off
hp3k systems revert to battery
nt system displays a dialog box: utility power off, using battery, nt
                                 will shutdown soon

after 1 minute, power comes back on
hp3k systems powerfail recover, dtc's download
nt system displays a dialog box: utility power back on. off battery.

The lesson
----------
It is possible to have a pc server like NT setup to maintain
similar levels of protection as our hp3k systems. In fact, since we don't
have our hp3k systems all plugged into a UPS we have less protection
then our nt system. (and I didn't get any pretty dialog boxes from my
hp3k systems!)

This probaby isn't *news* to many of you, but all the traffic about the
3k's powerfail resilency might give the impression you couldn't get equal
security in another computing environment. That isn't always the case
as this example shows.
