Dynamically Controlling Server Power Consumption and Reducing Data Center Peak Usage by 16 to 18 Percent

Reducing power consumption is important to all CSPs but for NTT Data Corporation, based in Japan, a magnitude 9.0 earthquake meant acting fast to reduce power. As a result of the earthquake, the country’s nuclear reactors were shut down, leaving power in short supply. NTT tested two methods of controlling power consumption: using servers based on the Intel® Xeon® processor E5 family, and deploying Intel® Data Center Manager to aggregate the information from these servers and carry out power capping policies.

Using the Intel Xeon processor E5 family, Intel® Node Manager and Intel® Data Center manager, NTT Data found it could:

  • Reduce peak electrical power usage in the data center by 18 percent by reducing the performance of high-load servers to 90 percent; and
  • Cut 16 percent of the peak electrical power usage in the data center by reducing the performance of low-load servers to 70 percent.

This result allows NTT Data to provide a reliable and stable service to clients entrusting their mission-critical systems to the data center.
