Enterprise Serves

Data centers use an astounding 2 percent of the electricity in the United States.[1] Enterprise servers, in millions of data center spaces across the country, run the essential functions of business – email, storing critical information, managing databases, displaying web pages, etc.  Mostly thought of in the context of endless server racks in Costco-sized enterprise data centers, in actuality 40% of servers can be found in ubiquitous server closets and rooms found in almost every commercial building.[2]  In other words, like computers, the ENERGY STAR server savings opportunity can be realized by almost any organization with an office environment.  

ENERGY STAR certified servers come in the several form factors – blade, multi-node, rack-mounted, and pedestal – and offer the following energy saving features:

  • Efficient power supplies that limit power conversion losses and generate less waste heat, which reduces the need for excess air conditioning in the datacenter facility where they are housed;
  • Improved power quality which provides building-wide energy efficiency benefits;
  • Limits on idle power draw for one and two processor rack mounted or pedestal servers.  
  • Disclosure of Server Efficiency Rating Tool (SERT) results to accommodate comparison of server efficiency under different usage scenarios.
  • Capabilities to measure real time power use, processor utilization, and air temperature, which improves manageability and lowers total cost of ownership;
  • Advanced power management features and efficient components to save energy across various operating states, including idle; and

Did You Know?

Servers that earn the ENERGY STAR will, on average, be 30 percent more energy efficient than standard servers. If all servers sold in the United States meet this new specification, energy cost savings would approach $800 million per year and prevent greenhouse gas emissions equivalent to those from over one million vehicles.

A set of tests conducted jointly by US EPA, HP, and Microsoft demonstrate that replacing an older server with a new ENERGY STAR-qualified model will save energy and deliver more processing power in the bargain. In some of these tests, the new ENERGY STAR server consumed 54% less power than older model servers.  Learn more. PDF (2.67MB)
