- Cooling for a small server room 8 answers
I reorganized everything in a room to make it into a "official" server room so to speak.
It was full of boxes, old junk, etc. and right now there is only a cabinet with office material. The reason I cleaned it out is because I think that random stuff (boxes) generate more heat and more dust (is this correct?) Im not too much of a fan of letting random employees enter in and out of the server room (we are a small company of only 20 but still) but that cabinet is pretty large and cant be moved...
Anyways, there is a rack with 4 exhaust fans inside of the roof of the rack and inside with 1 server and one NAS. One is a R730 and the NAS is a QNAP. Besides the rack, there is another server which is a PowerEdge 2900. It is outside the rack because in rack there are several battery packs for a UPS we have.
I have my doubts about the cooling inside the room. I have the "luck" that there is a AC unit in the room but the problem is that there are also AC units in the next rooms and if those ACs are on heat, the AC inside the server room does not allow cooling. It is either all heating or all cooling. Meaning I cannot have that AC unit spitting 24/7/365 all year except in summer.
Further, the room I would say is 4 meters by 4 meters (small) and has no windows. You enter it from the common office.
My question is what would be a good cooling plan? Right now, our idea is to make a chimney from the top of the rack to the roof where the fans would blow air out. The problem is that there is 0 airflow to bring cool air in. A solution is that even though you enter the room thru the office, the right wall gives directly to a large factory which is basically cold. From there, we had a idea of putting a fan that draws cold air from the factory into the server room. I think its a idea but I imagine some kind of filter would also have to be put in place to avoid dust.
Is this a good plan? What would the ideal temperature be for something like this?
