Spot coolers can cost you more to operate, not less. The heat extracted
by the spot cooler has to go someplace. Sure, you are cooling data
center room air and blowing the chilled air into a rack. But the spot
cooler is still blowing the extracted heat out the top + the additional
heat generated by the spot cooler itself. If you have one of the larger
units, you may be expelling the hot air into your plenum space above the
T-bar, or out into your office space where the building AC has to now
work harder to remove the heat you are pumping out of the data center.
They are awesome as a stop-gap, or temporary solution. But they are not
a replacement for a properly configured cooling system.
Thermodynamics - It's the law.
P.S. - We keep our room around 75.
P.S.S. - Take the Watts for the room. If you have a whole room UPS just
take the KVA output from your UPS meters and multiply by the Power
Factor for you UPS (Usually .7 to .9) to give you total Kilowatts. Take
the total Kilowatts * 0.283 = Approximate Tons of Cooling needed for
your data center.
KVA * PF = KW
KW * 0.283 = Approximate Tons of AC
Or if you know how many watts then it is Watts * .000283 = Cooling Tons

It's not the temp of the outside air that is the problem. It's the
temperature of the server interior. All recent servers have temp
indicators built on board. I would look at those. I have not found that
with the room that hot that the servers can cool themselves properly.
(even a single server or PC for that matter) I'm sure that the temp can
be bumped up from the 65 degrees that many server rooms are running at
and the server would be just fine but I'd be surprised if it was
anything above 75. Of course room size and amount of equipment plays
into that as well.
For the LEEDS certification, I would see if purchasing a spot air
conditioner would earn you any points. No need to cool the whole room if
the idea is to get the severs the cool air they need to intake. We have
started to place portable air conditioners at the rack. They are
inexpensive and efficient and no longer require a drain for water. This
cools the rack while leaving the room at normal temp.
Another client recently took a step further. The server room is fairly
large but only holds a single rack of 5 servers. Panel equipment is
mounted on the wall next to the rack. They recently installed a folding
wall with sound proofing to section off the room. They can now use the
rest for other storage and temp office space. The portable air
conditioner in place is still keeping the rack nice and cool.

Hi all-
This is off topic, but an interesting question.
Our building is going through a renovation. Part of the renovation is
transforming the building into a green building (LEEDS certified gold,
or maybe even platinum). This question hasn't come up here, but it does
have relevance to us.
I was at a conference yesterday and a Microsoft guy was talking about
virtualization, how it could save you money and whatnot. He mentioned
that at the office he works at, as another money-saving feature they
keep their server room at 90 degrees (!). It saves them money on cooling
and he says has no adverse effects on their servers. He says the biggest
damage-inducing facet of temperature is big swings in temperature, that
just running hot is not a problem. What do you all think?
Thanks,
Rob
