I did like the old card and impact printer days tho. That was when
computers leaked oil on the floor and a CPU was the size of a sub zero
refrigerator.

There were a couple of weekends where "the computer" was shutdown
because they had to turn off the water main for some reason or other.

That is a strange thing to say. The water cooled systems did not use
tap water anywhere in the system.
Both loops were distilled water and self contained. I suspect they
were down for something else.

All I know is that when they were working on the water mains the
computer was shutdown. It must have been for the chillers or something
like that.


I never got on the roof of the USDA building. They may have had
cooling towers up there but you have already pointed out why it was a
bad idea if "availability" was important to you.
The units I saw were usually regular Liebert 10 ton freon chillers
that pumped distilled water and glycol.
The machine side used some kind of poisonous water stabilizer and
distilled water.

Have you ever seen the results of the testing of a Halon fire
suppression system? Carolina Power and Light was testing their new data
center in Raliegh, NC and their insurance company wanted to make sure
that the Halon system worked. So with the Data Center empty of people
and equipment they fired off the halon system. It looked like a war zone
afterwards. Most of the heads on the pipes came flying and became
missiles. Floor tiles were dented, walls had big holes in them and the
whole place was a mess.

They didn't have a test fire, they just wanted to make sure that when
you hit the button that the tanks would empty and and the Halon would
come out of the ends of the pips.

Bad system. Only time I saw one go off was a new bank data center and no
one knew there the abort button was. Carpenter (union) was forcing a Skill
saw through some wood for a ramp, dull blade, or something and the smoke
went directly to the detector about 2' away. Alarms went off and we all
left the room, while about $3300 of Freon was dumped. Do damage other than
the refill cost for the tanks.
