Server room temperature

[netadmin]

We finally purchased a new air conditioner for our server room. It still has to be installed, but I am starting to think about what temperature it should be set at.

What temperature do you keep your server room(s) at?

Close to boiling... no air con

Mine was at 39 degrees (not a joke) feb/march last year. Asked my boss for an air con unit (I'd only just started) and it arrived the next day. Free standing but connects to a pipe that vents outside. works a treat, room is always around 22-24 degrees now

having said that the atmosphere in the room is extremely dry, I'm sure it's why i've gotten so many chest infections over the past year. Hey ho, new school in 2009

If I could control the temperature exactly i'd set it at 20 or 21. any lower and it'd be too cold for sitting working in. I do have to work in the room though - it doubles as my office. i'll post some pictures on monday to show you the hell hole

I got one installed in January and am now feeling the benefit fully. Lowest it can be set is 21c and theres a distance barrier when you walk into my room.

Roll on June/July.

I won't mention August as only the workers are in school then.

I used to put ours on as low as it would go (mainly cause when i was in there i was stuck behind the rack where it's warm) and that was a nice frosty 18degrees. I think the preference was around 20-21 by the other techies / head of ICT

Problem is....when the power trips it didnt have enough time to reset and we'd be working away recabling when the builders tripped the breakers and when it came back on it was blowing VERY hot...we didnt notice and there was condensation starting to form on the rack. Shouts and panic to off the thing and wait for it to reset itself...not very amusing.

I think we found the setting for it in the end.

You should maintaint he room at 18 - this allows a degree of headroom should the Air-Con fail to keep up.

Note that while a good server can keep itself runnning everytime it goes past its recommended operating temp you are reducing (at leat potential) its lifespan. You are certianly reducing the life of the fans. In my case the units will run with an ambiant of 38c and an internal of 45c - but thats skating on thin ice.

You must also remember that if you have any UPS battiers your are looking at serious problems if they exceed 24c.

Thats interesting as I was recently (last week) informed by our Air con man that any lower than 20 degrees C is likely to cause a static build up & condensation could start to become an issue.

At my ols school the server room which was my office as well was kept at 18 degrees by me and had no problems with condesation

[Colditzz]

I must admit to being slightly sceptical when I was given that temperature, however, he is the air con man, and I am not

[localzuk]

We maintain at 18 degrees also, and have no problems with condensation.

[Geoff]

The air con is set to 18 here.

[Anglo_Jaxon]

When our server room hit "40" 2 years ago I threatened to switch off the server and switches.

I was given a room fan... and asked "will this help?"

Our air con is now set to 18 ish

By increasing to temperature to 20-22 or so, you won't affect the workings of your servers, but the AC will be working far less hard, and you'll save the penguins too!

[sidewinder]

I have ours at 19

We have 2 units - one predates me and was fine until last summer where it started to really struggle due to the amount of equipment, so we got a huge new unit fitted (£10k)

It copes perfectly now, I was sceptical as it didnt seem that cool during the winter but its been lovely on the few hot days we've had so far

Thats a new one

How can static build up if its all earthed?

As to condensation, most Air-Cons draw the water out, so in my case at the moment its running out into a sink. To some extent having the room dired out is a good thing as hummity is much worse than just being hot.
