5 Cooling Solutions for Data Centers

Posted In DigitalOlympus Feature Articles, DigitalOlympus News - By Josh Cole On Friday, September 27th, 2013 With 0 Comments

“Cooling is by far the biggest user of electrical power in the data center,” stated Steve Carlini, Senior Director of Data Center at Schneider Electric. And it is also frequently cited in surveys as one of the most problematic issues data centers have to deal with on a regular basis. This means many data centers don’t cool as efficiently as they should.

It’s a fact: a cool environment helps electronic equipment perform better. Increasing cooling capacity, as well as cooling efficiency, can affect your business performance significantly. We’ve all had our share of cooling problems in the past. The key is to prevent them. (For extra input on the matter, please read this excellent white paper by Peter Hannaford).


How to Solve Cooling Problems in Your Data Center?

Data center efficiency has become crucial for business success over the last few years. And keeping your data center performing efficiently has a lot to do with keeping it cool. If you can’t migrate to a professional offsite colocation data center right now (something that I highly recommend), then follow this tips to prevent some cooling issues:


  1. Learn the lingo: You must broaden your vocabulary with some basic definitions related to data center cooling issues. You need to know terms like ASHRAE, Chiller and Economizer; you also need to understand acronyms like CRAH (Computer room air handler) and CRAC (Computer room air conditioner).

  2. Take care of regular servicing: Like most electronic equipment, a data center requires a “health check” every now and then to prevent problems. Usually when you think about improving efficiency you immediately think about extensive upgrades, and yet maybe all it needs it’s a minor check to find a flaw in the cooling infrastructure.

  3. Adjust the air pressure: There are some new cooling methods from recognized brands that can reduce costs up to 50% (according to an article called ‘Rethinking Data Center Cooling for Serious Savings” published on greentechmedia.com), by combining traditional strategies, like precooling, with a new system that pressurizes the space directly over the servers.

  4. Install blanking panels: Hannaford said in his white paper that, “Installation of blanking panels prevents cooled air from bypassing the server intakes and prevents hot air from recycling.” He also stated that this is one the most ignored best practices out there, even though failing to follow it causes overheating.

  5. Add a hot-aisle containment: While adding a cold-aisle containment might be easier, a hot-aisle containment is actually a better alternative to control temperatures. This unit allows a more efficient airflow (front and rear) and helps keeping the heat out of the data center, making it easier to cool down the room.

Keeping a data center cool is challenging, but it will have an incremental benefit in a business performance.

I admit that maintaining a top-notch, in-house data center is time-consuming and it’s definitely costly for small companies; however, don’t give up on the idea of managing your business information with a data center. Why not looking into colocation services from a telecom company? Remember: Data centers play a major role in a company’s success nowadays.
