10 Steps to Increasing Data Center Efficiency and Availability

A systematic approach to building data center infrastructure management.

Have any unused or underperforming servers lurking in some darker recess of your data center? Known as being "comatose," these servers are no longer performing useful work, but are still occupying expensive real estate and consuming energy. Track them down and power them off to save money and make your data center that much "greener" by conserving energy and reducing your carbon footprint.


To get an idea of your savings potential, check out contributor Michael Stevens' Green Data Center calculator. This tool provides you with a quick approximation of the results you can expect from decommissioning servers that aren't doing anything but eating up resources and space.


Or, if you have servers in your farm that aren't doing mission-critical work around the clock (such as those that serve to back up data), you may be able to avoid needlessly consuming energy by scheduling power-downs for those servers as appropriate. Stevens also uploaded a calculator tool that can give you an approximation of the results you can expect from a temporary power-down strategy.


These tools and resources can help you identify more opportunities to bring green practices to your data center:
