Ravi Raj of Net Rack advocates the following key elements that can help in creating energy efficient datacenters:
Equipment in data centers generates lots of heat and to suck out this hot air, a proper mechanism is to be followed. Thermal management helps in improving airflow in the racks and also by preventing the mixing of cool and hot air. Companies can opt for solutions which can increase the inflow of cool air inside the server racks and help exhaust the hot air. This ensures that all the mission-critical equipment runs cool with more reliability with an increased MTBF, saving energy costs and capital cost on the AC plant.
Implementation of hotaisle/ cold-aisle containment solutions can be very helpful in cooling in data centers. The increase in cold air from the front side and exhausting the hot air from the back side of the rack enhance cooling. Separating the hot air from the cool air is the key to efficiency.
White racks can be helpful in saving a few bucks for the company. The scientific fact that the dark colors are better absorbers of light and therefore better radiators of heat, whereas white color is more of the reflecting nature and can be proved efficient with sending back
