Ask the Engineer – What can be done to become more energy efficient and incorporate Green IT in the Data Center?

Posted by Bob Parente on Jan 8, 2011 10:01:00 AM

Not only for the environmental reasons that you may expect, but for the economic benefits seen by incorporating Green IT in the data centers. Going “green” means measuring, analyzing and controlling power usage to enable effective capacity planning along with aptitude to make change for decreased usage – all leading to improved efficiency and a controlled carbon footprint.

Data Centers today are experiencing:

  • Unavailability of Power
  • Rising Energy costs
    • The per-square-foot annual energy cost in data centers is 30-80 times more than a typical office building.
    • The cost of electricity and supporting infrastructure for three years surpasses the capital cost of IT equipment.
  • EPA says data centers account for 1.5% of annual U.S. electrical consumption.
  • Energy legislation is coming.

Power Measurement Leads to Improved Efficiency, Improved ROI and Helps You Achieve Your Green Initiatives

  • Measure power usage
  • Measure power usage effectiveness (PUE)
  • Make adjustments based on the power monitoring information to reduce energy usage and CO2 output
  • Continue to use power management tools such as Intelligent Power Distribution Units (PDUs) combined with a Power Management system (Sentry Power Manager from Server Technology) to evolve data center efficiencies saving the company money and driving your green initiatives.
