5 Steps to Optimizing Data Center Cooling

This is an excerpt from The Essential Guide to the Data Center Facility of the Future.

Many data center managers have a “colder is better” philosophy. After all, the cooler the temps and greater the airflow, the better you can meet customer service level agreements (SLAs). However, keeping it too cool causes waste and increases your energy bills.

Here are five steps to optimizing your data center’s cooling:

  1. Address containment to separate incoming air from exit air. This allows you to maintain your desired temperature, increase your availability and meet SLAs. The hotter the air, the more efficient your heat rejection.

  2. Decide what supply temperature to run your IT equipment. The recommended temperature range is 65° to 80°F. If you run at higher temperatures, your server fans will ramp up and use more energy.

  3. Use a variable capacity system that adjusts to your IT load. In legacy data centers, fans deliver too much air and waste electricity. With a variable capacity system, you won’t waste energy by using too much air or have reliability problems caused by not delivering enough air.

  4. Put controls in place to optimize your data center. This includes measuring temperatures in front of the servers and in the aisles, as well as controlling the cooling equipment to maintain the right amount of heat rejection.

  5. Use economization to lower your costs and power consumption. For example, bring in outside air to reject heat without using mechanical refrigeration.

Legacy cooling systems consume roughly 40 percent of a data center’s power—and it’s all waste. Using the best practices outlined above can reduce this to less than 15 percent of your data center energy’s consumption.
