Server Room Temperature Recommendations

[TheTwist]

Apologies if this is not the forum for this. 

 

I am trying to work out what room temperatures are recommended  in a server room  should be. There's loads of different answers on the internet.

What would you suggest the coldest or warmest temperature should be? I have about 60 servers in this room

Other than mechanical hard drives, computers usually aren't that sensitive to temperature. Most modern processors can work reliably for years at up to 80c+ same for memory and motherboards... as long as you keep temperature at or below, they'll be happy. 

 

Hard drives prefer lower temperatures, see Google's hard drive study made on tons of hard drives and servers running at various temperatures : https://static.googleusercontent.com/media/research.google.com/en//archive/disk_failures.pdf

See 3.4 temperature, but look at the other pages as well. Basically when it comes to mechanical drives, too cold increases the probability a drive will fail , and too hot increases failure rate after 3-5 years of 24/7 of use 

SSDs aren't that picky. flash chips like temperature, it's good for them (50-70c is fine for flash chips) as long as the controller stays within reasonable temperature (usually less than 85c for most controllers, but I'd recommend less than 70c)

The humitity is important, as to low and you get static, to high and moisture can build up on components.

You should aim for about 76-78F in your cold aisels. The trick is to make sure you have stable temps on your server intakes. As you will get hot/cold spots which you want to minimize.

 

So by no means is this absalute, but this guide should help.

in all datacenters i work the cold isle temp is usually between 10 and 20' C

 

this is ofcourse handled by big industrial airconditioning. if your server room doesn't have this capacity a bit higher won't hurt the servers, just make sure the hot air has a way to escape your server room too.

Thank you all for the comments. I'd say keep my temperature sensor to alert at 25C  just to be on the safe side. 50 of the servers do use their max CPU power.

You need to factor in equipment heat-load to size appropriate ac tonnage; both now and into the future as you add equipment.

What do you use 60 servers for

6  are storage and we have 50 for CGI rendering an the rest for other things.
