Desenvolvimento de solução ecoeficiente para data center

Abstract

The survey evaluated the benefits, in terms of eco-efficiency, of IT virtualization from the main data center of the National Nuclear Energy Commission (CNEN). The eco-efficiency index chosen was the energy consumption of servers. The survey quantified CNEN's data center servers, and through exploration, identified the traditional servers, virtualization cluster servers, as well their respective virtual machines. The energy consumption of the servers was estimated using the tool Cost comparison toolkit: Calculating server power usage. The results show that all analyzed servers have low processing usage; the virtualization cluster of CNEN operates with excess resources on a scale that would allow the shutdown of two servers without compromising the operation of the cluster; a single cluster server is enough to house all non-virtualized servers in terms of processing and memory. The survey concludes that virtualization of traditional servers is the best way for CNEN to achieve a reduction in the energy consumption of its data center and that the virtualization cluster is wasting energy because it operates underutilized. This research contributes to a deeper look at virtualization as an alternative to data center management in public administration.
