What Is Data Center Energy Efficiency?


Data Center Energy Efficiency is an important part of any office management plan. The first step is to organize where you will place your cooling plant and air handlers. Most sources recommend a central location for these units instead of using distributed air conditioning units. A variable speed chiller and preferably a control system that is integrated into an overall system are also advisable. That way the heating and cooling do not take place together, which is very inefficient.

Another problem area is humidity control, which needs to be addressed as well by the control system. The air control problem should take into consideration alternating sections for hotter equipment under the cold air outputs while placing the cooler equipment in the hotter parts of a room, under the air return units. There should be no part of the room that isn’t in some part of this air supply pattern. In addition, the servers and other equipment needs to have all of the heat exhausts facing into one aisle while all the intakes (or fronts) of the machinery is facing to another aisle shared with the fronts of other equipment. This arrangement also allows for an increase in the amount of servers, and other equipment, can be put into a certain space. The cold/hot arrangement makes that increase possible.

A further concern should be about the efficiency of all of the servers in the network. The best way to make servers more efficient is to make these more efficient servers oneself. That is instead of buying less efficient pre-assembled servers, one should buy the components and assemble the more efficient servers—customized by need. A second, more recent innovation, is to put one’s server needs together with other business so that the energy demands are distributed among the contributors to the collective. The cloud businesses are one excellent example of a successful version of this approach.

Another choice, and one that can be used together with the first two as well, is to buy EPA-certified equipment that is certified for its energy efficiency. This type of equipment has built-in energy saving features such as Sleep/Idle routines, power management profiles for a variety of setups, and so on. Finally, security is another issue that will increase the data center energy efficiency. The less energy that is wasted on dealing with invasive code and hacking attempts the more that is available and/or not demanded in the first place.
