Eight Tips: Reducing the Environmental Impact of Computing in 2008

PLANO, Texas - There is a drumbeat of change in business and society around 'green'. Concerns about the environment is at a fever pitch. Green, for all the right reasons has become red hot.

With a steady demand for green information and action by corporations and governments, the IT company EDS, offers tips on greening your IT.

To help corporations and governments kick-off the new year right, the EDS Fellows have highlighted eight ways CIO's can extend the life of existing facilities and reduce the environmental impact of computing in 2008.  


1. Virtualize Servers.  The first option is to move from the "one application - one server" paradigm many organizations have fallen into. Server virtualization  allows multiple applications to operate securely within the same physical server. Moving the current average server utilization from  15-20 percent to 80-90 percent allows fewer servers to do more work using the same energy profile. 

2. Turn off Unused Servers. The easiest power to save is the power that isn't used. Servers and disk drives should be on only when they are needed, so sophisticated  operating processes must be in place to bring servers back online      whenever increased demands require them to do so. 

3.   Employ Power Saving Techniques.  The third option is to employ power saving techniques now familiar to most laptop users. When demand allows it, organizations can run their  servers at reduced speed which lessens their consumption of energy.

In addition, an enterprise should always choose a server with the  highest power supply efficiency available with the selected configuration. 

4. Optimize Applications. The fourth option is to optimize applications being run in the data  center. Bloated software, inefficient software, or even software that produces very little business value all need to be pruned, optimized and even discontinued to put a lesser load on servers.

5. Perform Rigorous Maintenance.  The fifth option is more fundamental, but also very achievable. Data       center managers can improve the efficiency of their facilities by  rigorous maintenance to ensure all equipment is operating at the peak of efficiency as well as modifying layout and configuration of  equipment to reduce cooling requirements. These and many more efficiency steps will increase overall data center efficiency and  lower the carbon footprint. 

6. Move to Higher Density, Multi-Core CPUs.  The movement to newer, multi-core CPU designs will deliver       significant efficiencies, because of their lower voltage  requirements. Eight, 16, 24 and higher "processors on a chip" allow  for fewer server blades in a rack driving up efficiencies and driving  down electricity usage.

7. Pay More Attention to Operating the Infrastructure.   We have become so accustomed to "cheap computing" that we have become  lax in our process of procuring, deploying and operating the infrastructure upon which so much of our modern society depends. However, when an enterprise looks at total cost of ownership and electricity costs exceed the purchase price of a server, the equation shifts in favor of higher efficiency and rigor which is good for the  bottom line as well as for the environment. 

8. Cash in on Being Green. It is important to look for innovative applications of IT that makes real impacts for an enterprise and its customers.  For example, an enterprise can use Dimmable Addressable Lighting Interface (DALI) in       electronic ballasts networked to sophisticated lighting control software that reduces electrical usage by up to 40 percent, or use programmable thermostats and schedules to standardize the       temperature, pressure, humidity and set points for occupied and unoccupied periods in all buildings. These technologies require  integrated IT to function and provide a rapid return on investment.  The world will see an explosion of IT being deployed as we move to a lower energy regime in new and existing buildings throughout society over the next several years. The business advantage of consuming less     electricity reduces both the cost structure and carbon footprint of the enterprise, which is good for business and the planet.
