With it being summer, it’s got me thinking about heat on a daily basis. Especially server room heat. I’ve been through my fair share of server rooms and I’ve seen all sorts of solutions to the ever increasing heat problem. It seems more and more applications require a specific server to run; and more and more software requirements state that this piece of software can’t run on the same box as that piece of software. This leads to purchasing more servers and ends up leading to a lot of power draw and more heat in your server room.
Some people decide to cool servers the proper way by installing the proper cooling units into their server rooms, and other people decide to go the old fashioned way by leaving the server room door open or by putting a lot of home based oscillating fans in the room. Unfortunately this leads only to two very bad things, poor physical security and recirculation of hot air over the already warm servers.
If you need to cool your server room and don’t have the proper cooling, you seriously need to figure that into your next budget so you can have it. Also see what you can do to consolidate the roles of your servers so you have less servers taking up valuable space in your server room and also less servers generating heat.
As I’ve mentioned before, Blade servers and VMWare are a very good idea for server consolidation. Not only are they good for saving power but they are great for keeping the heat down. Also with Windows 2008 out now and Hyper-V, there really is no reason not to try and virtualize even if you are not a VMWare expert. Any way you slice it the thermal savings will be substantial.
