Data centers have evolved dramatically in recent years, due to the advent of social networking services, e-commerce and cloud computing. The conflicting requirements are the high availability levels demanded against the low sustainability impact and cost values. The approaches that evaluate and optimize these requirements are essential to support designers of data center architectures. Our work aims to propose an integrated approach to estimate and optimize these issues with the support of the developed environment, Mercury. Mercury is a tool for dependability, performance and energy flow evaluation. The tool supports reliability block diagrams (RBD), stochastic Petri nets (SPNs), continuous-time Markov chains (CTMC) and energy flow (EFM) models. The EFM verifies the energy flow on data center architectures, taking into account the energy efficiency and power capacity that each device can provide (assuming power systems) or extract (considering cooling components). The EFM also estimates the sustainability impact and cost issues of data center architectures. Additionally, a methodology is also considered to support the modeling, evaluation and optimization processes. Two case studies are presented to illustrate the adopted methodology on data center power systems.
O raciocínio que guiou a elaboração deste estudo considerou a responsabilidade social empresarial e a sustentabilidade organizacional como dois caminhos estratégicos possíveis de serem adotados pelas organizações em prol de ofertarem contribuições para o alcance de um desenvolvimento sustentável. Para tanto foi realizada uma pesquisa básica, qualitativa, exploratória e bibliográfica. Ao fim do artigo considerou-se que a maturidade e a ramificação da responsabilidade social empresarial podem ser observadas na sustentabilidade organizacional, uma vez que a primeira constitui um caminho organizacional estratégico inicial e a segunda um caminho organizacional estratégico avançado, ambos interessados em conceder representatividade para as organizações na busca por um desenvolvimento sustentável.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
