ABSTRACT
Cloud computing and storage solutions enable end users and enterprises to store their data and process their services in third party data centers. The fast growth of data center in size and in number makes them become huge energy consumption points. Some researches claim that 70% energy for a data center focus on server running and cooling. That is why, recent researches proposed to turn off certain switches in data center where little traffic flows through. However, when those switches are turned off, the structure of the data center becomes vulnerable to failures due to low connectivities between servers. This paper aims to overcome this weakness by proposing a way to build a data center where unnecessary switches can still be turned off while the data center remains survivable upon any single failure. The simulation results show that the proposed solution makes data center survivable while still saving a lot of energy.
