How to decrease humidity level in a server room

I heard that using a dehumidifier can cause static charge buildup in the room. Then the server room was designed by an idiot. ANY server room I have seen in the last 30 years had the racks and (this, ...

Server corrosion, air conditioning and climate control

The way an air conditioner dehumidifies is (in brief) the high-pressure refrigerant is forced through a small opening, leading to lower pressure on the other side of the opening. That decompression ...

Minus degrees in server room

The recommended temperature range for your servers is not too wide, usually it's wider for humans :) So yes, the -15 degree in Celsius is probably too low, but to be sure, you have to ask the ...

Does the power consumed by an air conditioner adds to the total heat generation in a server room?

Yes and no. Air conditioners obviously do generate heat from their own power usage, but the formulae to calculate how much equipment-generated heat they can deal with already take that into account — ...

How to decrease humidity level in a server room

You need to add heat to the server room. Enough heat to make the A/C work harder to maintain your set temperature, but not so much heat that the temperature rises above the desired range. A well-...

Passive cooling options for server room in case of extended power outage

There is no problem to start with - or a minor one. Make sure the cooling system is on the USV and possibly has a secondary USV giving it 5 minutes more and you are good. Done. See, the moment power ...

For reference, Lenovo SR650 servers should not be operated below 5 degrees Celsius. I suspect similar guide lines are given for other rack servers.

Why do technicians recommend a lowest temperature for server rooms?

First off, its NOT bad from the servers POV to run rooms colder, within reason. The links you have imply, or downright state the reason - cost. Keeping servers cooler costs more money (and wastes ...

This would seem "within the bounds of normal" - maybe slightly on the warm side depending on how your ventilation is set up and where its measured. It likely also depends on the servers - more power ...
