How a Data Center Cooling System Can Reduce Downtime

by Jason Blalock on June 30, 2016

data center cooling systemAs your server setup and data centers grow, having a solid data center cooling system in place becomes increasingly important.  Whether you're considering adding one to your own in-house data center, or shopping around between third-party centers, having a modern and well-maintained data center cooling system will reduce downtime and save money in the long run.

Heat, of course, will tend to build up among any collection of electronics, with more heat being generated as the collection grows.  This problem gets worse if the data center is in a relatively small room, leaving the rapidly-warming air with no place to go.  Further compounding the issue is that server and data center equipment tends to be less heat-tolerant than off-the-shelf consumer gear, so overheating can quickly become a very costly problem.

Data Center Cooling Systems:  A Vital Piece Of Insurance

There's no particular magic to data center cooling, it mostly just involves smart placement of cooling units along with plenty of airflow.  Humidity is another factor which can harm electronics, so  humidifiers or de-humidifiers are often added to the mix depending on the local environment.  

It still requires an expert to set up and maintain properly.  However, the results are worth it:


1 - Less Downtime and Equipment Replacement

Poor atmospheric control in a data center can drastically reduce the lifespan of equipment, and greatly increase the chances of a catastrophic unplanned outage when a piece of hardware fails. Regular maintenance of the system  will also help spot external problem areas.

2 - Lower Energy Use

One "workaround" some operations use to try to avoid implementing more stringent data center cooling systems is to simply keep their server room very, very cold.  The problem is, this is incredibly wasteful, and often amounts to enough unnecessary power use. This will end up costing you more than it would be to just pay for a better and more efficient cooling system.  A well-maintained cooling setup can often help lower energy costs in the long run.

Data and server rooms almost never have to be cooler than 70 degrees Fahrenheit, and it's actually fine up to about 80.  However, 75 is considered the maximum "safe" temperature, just to leave some headroom.

3 - Better Efficiency From Newer Equipment

If you're still relying on the AC system built into your building decades ago, you're probably paying far more for cooling than you need to.  Today's climate-control devices are 30-50% more energy efficient than models from the 70s and 80s.  So, again, installing a modern data center cooling setup can ultimately end up saving considerable energy -and money- in the long run.

On a related note, it's worth mentioning that system's maintenance agreements are also becoming increasingly common among offsite providers.  In fact, a recent Schneider Electric study showed that data center customers were asking for guaranteed cooling system maintenance agreements at the same rate as those wanting guaranteed UPS maintenance.  

When so much is on the line, it's not worth risking equipment failure or damage due to faulty cooling systems.

If this is something you haven't thought about before, it's definitely time to look into a better data center cooling system.  While hardware manufacturers are trying to increase the heat tolerance of their hardware, it will still be a long time before they can run at temperatures much over 80.  In the meantime, prevention is the only policy when it comes to overheating.
