Abstract

Cooling power occupies large portion of power consumption in a Data Center. Improving efficiency of cooling is one of the most efficient ways to reduce power consumption in a Data Center. However it is not obvious how we can find out sufficient but not too much operation of cooling facility. In this paper, we measure temperature of racks, servers and processors and power consumption of IT equipment and CRAC under several different conditions. From these investigations, we find out the following. It is possible to reduce cooling power by leading cool air to rack directly. Monitoring processor temperature and controlling number of CRAC and volume of air are useful methods to adjust the capability of CRAC.
