Ours is about 34C.
EDIT - Directly behind server racking.
That's a little warm isn't it?
Ours is around 18-20C.
Thats what we thought Our air con setup is not good. I was curious to see what other people are getting. Can you say where that temperature is taken too?
Sounds very warm to me. Ours goes mental if it goes above 25C normally its about 15 - 18C in them.
In your average server room, with the servers installed in racks I mean. You would want the racks facing towards the aircon's airflow, with the possibility of extraction at the back of the server racks somewhere.
Well...That's the normal type of setup I see at work on the sites I work at
There's work being done at the moment to increase temperatures, or at least find the maximum temperatures before equipment starts to fail. The conventional 18-20C thinking is too conservative. Most kit is fine up to 40ish, running the room that hot saves loads of money on air-conditioning.
Around 25 degrees C. It always feels a little hot, as the air-con's not great, but it's well within reason.
about 20C here. One main aircon unit at the front of the servers with 2 smaller ones behind it.
Not the best of setups but the server room is oddly shaped.
It was 30 degree's in ours today, the aircon unit is some pikey portable unit that sits in the corner and needs to be filled up with water every 5 minutes.
I must have told them 10 times that we need to plum in a proper system but they just won't listen, one day we will come in on a monday and everything will be dead... then i can say I TOLD YOU SO
There have been a few studys recently (one of my hosting team has been harping on about them)which have shown that as long as the humidity is low that computer rooms into the 40-50 mark are viable with little if any reduction in the life of the hardware. Obviously not nice to work in or near but gives a different twist on what the rooms can support. Also it appears that hard drives have an extended life in a warmer temperature...
[prepares for the barrage of comments]
You're quite right, as I mentioned above.
Our room is a pleasant 16-18'c; having just had a 2nd aircon unit installed; One is mostly idle; but having seen what happened with just an hour's downtime in the room, Resiliancy is key. The back of the racks are obviously a bit warmer; but not too warm to work comfortably in.
I think more than absolute temperatures being bad for kit, its the change in temperature which causes more issues?
18'c according to the AC's temp monitor.
We did have a problem 2 years ago when the outside unit overheated during 30'c weather, so we had a big ass unit installed. It is only 2 racks and 20 servers, but they do kick out some heat. This time of year I love going in there to cool off
Has been talk of putting the AC in the rack, where it can cool more efficiently.
The ultimate situation will be to have liquid cooling in the rack, and the servers plug into it to be liquid cooled themselves, like you'd plug it into the PDU now.
That way the air never gets warm, and you won't need to AC the room.
Do you have any links to the study findings?
2 aircon units, 20sq m room, running at 20-22 degrees. Mind u, its 32 degrees outside now so they a/c are being worked hard...
About 18C here, some hotspots at the back of particular server racks of course, but nothing above 21C
The environmental sensor probes are set to go off with a warning at 25C
Ours is 23 degrees
