Minimum data set for controlling data center equipment for energy saving management

Abstract

To reduce energy consumption in data centers, we propose architecture for coordinated control of information and communication technology (ICT) and cooling equipment. We also propose the minimum data set necessary for implementing such a function in data centers based on the ITU-T Recommendation L.1300, which received consent in September 2011. The significance and details of the minimum data set are presented. Other standardization activities on data set are also briefly summarized. This paper also presents the energy saving potential of coordinated control based on experiments in NTT. The results indicate that additional energy can be saved by adjusting the fan speed and temperature setting among multiple units of computer room air conditioner, in response to heat generation due to operation of ICT equipment.

Cooperative control architecture of fan-less servers and fresh-air cooling in container servers for low power operation

“…This consists of an optimized server load allocation system for energy saving and CRAC optimization control system. Furthermore, T. Hayashi et al have also mentioned about energy saving system in 2012 [21]. In this research, they propose architecture for coordinated control of information and communication technology and cooling equipment.…”
