Data centres that require energy to run servers and provide cooling account for almost a quarter of global carbon dioxide (CO2) emissions from information and communications technology (ICT), according to Gartner. Gartner’s estimate follows its finding in April 2007 that the ICT industry produces 2% of global CO2 emissions, placing it on par with the aviation industry.
Rakesh Kumar, research vice-president at Gartner said, “Not enough attention has been paid to reducing the data centre’s carbon emissions. Organisations should aim to keep their data centre CO2 emissions constant. This will help curb excessive data centre growth and act as a counterbalance to deploying energy-inefficient hardware.”
Data centres account for such a large portion of ICT CO2 emissions mainly for three reasons, that includes lack of floor-space, a failure to house high-density servers and increased power consumption and heat generation. These three issues will also affect the cost of running a data centre. For example, Gartner predicts energy consumption of microprocessors alone will rise for the next ten years.”
To reverse the situation, Kumar offers five practical guidelines to CIOs and data centre leaders on power management:
Align with the corporate facilities groups: Understand the working practices, documented guidelines and corporate policies of corporate facilities groups. This will help to establish what is appropriate for specific problems, such as cooling.
Outline current energy use and costs: Establish financial models for gaining a granular picture of energy costs to understand where power goes (servers, cooling, UPS or power distribution) and how much it costs.
Establish a sustainable IT expert group: From an IT perspective, a small team (or, initially, an individual) needs to take ownership of the IT-related environmental issues and establish rules of engagement for making decisions, such server selection or data centre design.
Evaluate future technologies: These will include facilities-type of solutions and energy software management tools for the office environment.
Develop a green procurement programme: Get started on green IT procurement by adopting the environmental requirements set out by long-established, government-backed environmental labelling bodies.
