Could a big hole in the sheetrock violate some kind of fire code?

Possibly, but I promise not to call the building inspector if you do too. :-)

Hm. The stairway between floors counted as a big hole that violated
fire codes. But the Grex room is just more basement that happens to
be walled off from the rest of the basement, so I'd guess that a hole
between the two would be no problem. Then again, I'm asking the building
codes to be logical, which is probably a mistake....

Re 73-74: Greg's understanding was absolutely correct.

The dungeon is just a partitioned-off area. It already has a big hole,
in which we've fitted a door, but that doesn't have to be closed.
Cutting a hole in the wallboard is trivial, and the only permission
we need would be from, I guess. Valerie! The stairway they put in
is a modification of the building structure, and created a "flue".
Our room is just a box in the basement. In fact, if its studs were not
attached to the building, no permit would have been required (except
for the wiring).

(You may even have been able to by-pass the wiring inspection had your
box just been fitted with a 220 volt dryer plug and cord. The dungeon
would have then been considered an appliance ;-)

(Uh, except for the fact that Grex has four 15A circuits...)

(7.5 KW on a plug is not a problem.)

Silly question: is the landlord particular about Grex exhausting its heat
into his/her basement?

That's what we have been doing all along. The basement will not get
hotter because we ventilate the dungeon to cool it. Imagine a 1 KW
space heater in a room, which brings the room up to some temperature.
Now, put that 1 KW heater in an insulated box. That 1 KW must still
get out of the box and into the room - but the inside of the box has
to get much hotter than the room.

Rane, my point about permission, is the fact that we don't own that
room, no matter how much work and materials we put into it. If we start
cutting big holes in it, we're going to need the *landlord's* permission.
We've already got some flack from one of the building's owners over this.

We've had and continue to have pretty hot weather. Grex seems to be working
OK from this users perspective. Let it be, perhaps?

Is the high temperature in the dungeon shortening the life of any of the
equipment? Letting it run because it hasn't crashed *yet* could be
expensive in the long run.

On the bright side, I reckon we've seen the summer's hottest days
already (knock on wood). I'm surprised the equipment survived so well.
However, by next summer, we *might* have two Suns running, or a big
working UPS, or who knows what, so I agree with Rane: we shouldn't
let it be just because of good fortune up until now.

And equally important is some modicum of comfort for those dedicated staff
members that tend the machines. They've been joking about the heat now,
but it could cause them to make mistakes because of incipient heat stroke,
or just an urgent desire to get out of there.

Say, back to the earlier mention of liquid-cooled computers, PC Mag
reprinted this classified from the Atlanta Journal and Constitution:
"For sale: CRAY X-MP Supercomputer.
5 years old, original cost $12
million. With all support equipment,
ready to use. Asking $30,000 or
best offer."
At that depreciation rate, Grex should be able to afford one in a
couple years!! (Never mind that in a couple years, Nintendos will
probably be faster than Crays :-).

heh, heh, heh... Good one, Greg.
BTW, was anything done? This item just sort of died about a month ago. My
two cents: assuming we get the landlord's permission to do so, cutting a hole
in the wall and getting a flexible dryer duct to run to it from the Sun seems
to me to be the best option. Perhaps with a muffin fan at each end?

The concern died when the heat wave died.
I'm in favor of the flexible-duct-from-the-SUn idea myself.
We'll probably let this one slide till next spring now I think. We *want*
the heat in there over the winter.

I'm not so sure we can, Greg. We're going to have another Sun-3
chassis there soon, and thats going to add some 800w of heat to the
place. Since we were talking about using the old sun as a news
machine, this extra heat is going to stay there. The question
is, as it gets colder, can we leave things as they are now, or will we
be forced to deal with it now?

Frankly, I think the Sun-3 will likely get turned *off* for a few months
while we work the kinks out of the new system. By the time we can turn our
attention back to setting the Sun-3 up as a mail/news server, it will be the
middle of winter.

I think the duct from the chasis is the best idea. Maybe on such system
for each of the two suns. I think we should make up our mind on this
now so it can be in place when it starts to get hot again. I will
be happy to help with any of the construction. I am really handy
with things 'around the house'. I come from a family where when dad
gets bored he builds a sailboat. His current project is an airplane.
Yes, he is building an airplane. Let me know when you need help.
