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.
