Abstract(s)
Os Data Centers são a espinha dorsal da era digital, suportando a conectividade global e a economia baseada em dados, com uma tendência crescente na sua relevância à medida que a dependência da tecnologia aumenta, exigindo infraestruturas mais eficientes, seguras e sustentáveis, sustentando armazenamento, processamento e distribuição de dados. No projeto eletrotécnico, destaca-se a importância da redundância energética, com geradores, fontes de alimentação ininterrupta e sistemas de comutação, assegurando continuidade de alimentação mesmo em falhas, oferecendo escalabilidade, eficiência e confiabilidade. A eficiência energética é avaliada por métricas como o Power Usage Effectiveness, a integração de fontes renováveis, como energia solar e eólica, e sistemas de gestão centralizada, otimizando recursos e operação. Na comunicação, arquiteturas como Spine-Leaf e Fat-Tree suportam alta escalabilidade e baixa latência, com protocolos como Ethernet e InfiniBand que garantem velocidades de até 100 Gb/s, enquanto redes estruturadas utilizam fibra ótica e par de cobre para transmissão confiável. Normas específicas orientam os projetos de Data Centers, assegurando conformidade e
desempenho. Este panorama integra-se a um contexto de inovação, com avanços em computação edge, distribuição de corrente contínua e inteligência artificial, preparando os Data Centers para o futuro. O trabalho está estruturado em três capítulos principais. O primeiro introduz a motivação, objetivos e a importância do tema. O segundo aprofunda os fundamentos teóricos e técnicos de Data Centers. Por fim, o terceiro capítulo tem como objetivo apresentar uma análise abrangente da execução da dissertação, abordando os desafios e obstáculos enfrentados durante o desenvolvimento do trabalho, com uma avaliação crítica dos resultados obtidos.
Data Centers are the backbone of the digital age, supporting global connectivity and the datadriven economy, with a growing trend in their relevance as technology dependence increases, requiring more efficient, secure, and sustainable infrastructures to sustain data storage, processing, and distribution. In electrical engineering design, the importance of power redundancy stands out, with generators, uninterruptible power supplies, and switching systems ensuring power continuity even in failures, while providing scalability, efficiency, and reliability. Energy efficiency is assessed by metrics such as Power Usage Effectiveness, the integration of renewable sources such as solar and wind energy, and centralized management systems, optimizing resources and operations. In communications, architectures such as Spine-Leaf and Fat-Tree support high scalability and low latency, with protocols such as Ethernet and InfiniBand ensuring speeds of up to 100 Gb/s, while structured cabling networks use optical fiber and copper pairs for reliable transmission. Specific standards guide Data Center projects, ensuring compliance and performance. This landscape is integrated into a context of innovation, with advances in edge computing, direct current distribution, and artificial intelligence, preparing Data Centers for the future. The work is structured into three main chapters. The first introduces the motivation, objectives, and relevance of the topic. The second delves into the theoretical and technical foundations of Data Centers. Finally, the third chapter aims to present a comprehensive analysis of the dissertation’s execution, addressing the challenges and obstacles faced during the development of the work, along with a critical assessment of the results obtained.
