A business owner using a cloud service desires that the service operated in the cloud system will be operated with as few hardware resources as possible while meeting the service level agreement (SLA). In this paper, we propose a method to clarify the system configuration of the minimum hardware resource that meets the desired service performance (SLA). We conducted an experiment using memcached which...
The footprint of equipment is the actual size a computer device or equipment takes in the room or on the floor of a data center facility. Improvement of the average CPU utilization of data center servers is necessary to offer efficient service with a low footprint. In this paper we present a high efficiency cloud data center management system using live migration. Our system analyzes the power consumption...
In this paper, a cooling control system based on Model Predictive Control is developed in order to reduce energy consumption of the facility equipment for the modular data center utilizing indirect fresh air, while considering the relationship between energy savings and temperature management of servers. Furthermore, the developed cooling control system is applied to the actual modular data center...
To examine the use of fresh-air cooling to reduce energy consumption in container data centers (CDCs) regardless of location, a prototype fresh-air-cooled CDC was constructed in a Tokyo suburb, and a year-long operating test was conducted. Fresh-air cooling of information technology (IT) equipment does not require energy for air conditioning, and can be operated at reduced cost and energy usage. However,...
This paper proposes a cooling control method that reduces spikes in CPU temperature that occur due to fluctuation in the utilization of information communication technology (ICT) equipment based on model predictive control (MPC) for a modular datacenter. To cope with the fluctuations, the proposed method not only considers the server power consumption using a prediction model, but also switches between...
A cooling control method based on a model predictive control (MPC) for a modular datacenter utilizing the fresh-air is proposed. The proposed method reduces the total energy consumption of information technology (IT) equipment and cooling facilities in the data center, while considering a relationship between energy-savings and the temperature information of IT equipment. This method based on MPC...
