          Data Center: Power, Cooling, and Energy

          Data Center Savings

          The Economics of Energy Efficiency

          Hardware refreshes, efficient power and cooling strategies, and software-based approaches such as virtualization are obvious choices for organizations looking to cut costs in the data center. When you consolidate, optimize, and update your hardware, not only can you improve performance. You also can reduce power and cooling demands. The results are substantial savings in energy costs and a smaller carbon footprint for IT.

          Virtualization is a great starting point to decrease costs dramatically by reducing the number of servers you employ. For example, a standard server will typically run at an average CPU utilization rate from five and fifteen percent; a server running virtual machines will provide greater efficiency and run at an average of between 60 and 70 percent.

          A Greener IT Landscape

          • Underutilized servers produce a total of more than 80 million tons of CO2 per year
          • Many utility providers now offer financial incentives for data center reduction projects

          Though it shouldn’t be the only place you make changes, data center energy conservation is vital for the success of any green IT initiative. Using fewer physical devices, that can accomplish the same goals, requires less energy for operation, cooling, and related maintenance tasks. Any time you reduce the number of devices in the data center through consolidation and optimization, your savings multiply.
