Enterprise Servers


ENERGY STAR makes it easy to find an efficient server to meet your needs. Using our ENERGY STAR Product Finder, you can select from hundreds of certified energy efficient servers by the best, most popular and most trusted brands for your data center -- like Dell, HP, IBM, Lenovo, and others. In addition, you can filter the list of models by specific attributes, such as:

  • Form factor (e.g., blade, rack-mount, tower/pedestal)
  • Operating system supported
  • Memory
  • Processor Sockets

Servers are generally replaced every three to five years depending on their application. The next time you undertake your server refresh, specify servers that have earned the ENERGY STAR label. They are third-party certified to be energy efficient and use 30% less than conventional models by using the most efficient components (e.g., CPU, power supply) and ramping down energy use at low workloads. And remember to keep the power management settings engaged! Power management is a key component of ENERGY STAR servers and should not be disabled to get the full efficiency value of the product.
