Parte 4: Hardware do servidor e efici\u00eancia do processador<\/h2>\n

Substituindo datado hardware do servidor<\/a> Com um servidor mais novo e mais eficiente, voc\u00ea pode economizar espa\u00e7o e reduzir a energia e a energia necess\u00e1rias para executar o data center. Todo o design da infraestrutura do data center contribui para a efici\u00eancia geral. Esses componentes incluem processadores, mem\u00f3ria e sistemas de fontes de alimenta\u00e7\u00e3o.<\/p>\n

Processadores<\/h3>\n

O processador \u00e9 um dos principais consumidores de energia em servidores e o tipo de processador tem um grande impacto na efici\u00eancia do servidor. \u00c9 importante selecionar processadores equipados para corresponder \u00e0s tarefas necess\u00e1rias para a execu\u00e7\u00e3o. Existem alguns processadores por a\u00ed projetados para consumir menos energia e maior desempenho, dependendo da carga de trabalho. Alguns processadores sugeridos incluem os processadores Intel Xeon, Sun UltraSPARC T Series e AMD Opteron.<\/p>\n

Tamb\u00e9m existem recursos adicionais que ajudam a reduzir o consumo de energia no n\u00edvel do processador. Por exemplo, os processadores Intel t\u00eam Comuta\u00e7\u00e3o Baseada na Demanda (DBS)<\/a>, que adapta dinamicamente o consumo de energia \u00e0s cargas de trabalho, diminuindo os estados de energia do processador sempre que o desempenho m\u00e1ximo n\u00e3o \u00e9 necess\u00e1rio. Isso pode reduzir substancialmente o consumo m\u00e9dio de energia dos servidores que operam com taxas t\u00edpicas de utiliza\u00e7\u00e3o do data center. Os processadores Intel tamb\u00e9m possuem gerenciamento din\u00e2mico de energia. A entrega de energia aos principais subsistemas do processador \u00e9 gerenciada dinamicamente durante o tempo de execu\u00e7\u00e3o para otimizar continuamente o desempenho versus a efici\u00eancia de energia, conforme as cargas de trabalho variam.<\/p>\n

Mem\u00f3ria<\/h3>\n

Com o aumento da velocidade do processador, os fabricantes de servidores est\u00e3o adotando os FB-DIMMs (Dual Inline Memory Modules) com buffer mais r\u00e1pido, o que aumenta o consumo de energia. Portanto, instale os menos e mais densos FB-DIMMs para os requisitos, para diminuir a quantidade de consumo de energia.<\/p>\n

Suprimentos de energia<\/h3>\n

As fontes de alimenta\u00e7\u00e3o de um servidor devem suportar a carga m\u00e1xima com toda a mem\u00f3ria e slots PCI em uso, executando 100% de utiliza\u00e7\u00e3o. A maioria dos servidores opera com 50% ou menos da energia declarada, um intervalo em que muitas fontes de alimenta\u00e7\u00e3o podem ser relativamente ineficientes. Uma boa regra geral \u00e9 usar fontes de alimenta\u00e7\u00e3o que sejam pelo menos 80% mais eficientes em cargas de trabalho mais baixas.<\/p>\n

Definindo o "servidor com efici\u00eancia energ\u00e9tica"<\/h3>\n

A Intel estabeleceu uma defini\u00e7\u00e3o para o que \u201cServidor com efici\u00eancia energ\u00e9tica<\/a>" deveria fazer. A defini\u00e7\u00e3o inclui:<\/p>\n

\u201c\u2022 Reduza o uso de energia para fun\u00e7\u00f5es n\u00e3o computacionais por meio de:
\n- Fornecimento de energia com efici\u00eancia de energia (usando reguladores de tens\u00e3o, unidades de fonte de alimenta\u00e7\u00e3o e outros componentes com efici\u00eancia de energia).
\n- Processadores de efici\u00eancia energ\u00e9tica, incorporando recursos avan\u00e7ados de gerenciamento de energia e fabricados com a mais recente tecnologia de processo de sil\u00edcio, usando materiais diel\u00e9tricos de porta High-k para minimizar vazamentos.<\/p>\n

\u2022 Forne\u00e7a gerenciamento de energia de componentes de baixa granularidade (como gerenciamento de energia de mem\u00f3ria e comuta\u00e7\u00e3o baseada na demanda) ao longo da linha de carga para:
\n- Minimize o consumo de energia no sistema ocioso.
\n- Fornecer monitoramento e controle baseado em pol\u00edticas do consumo de energia da plataforma.
\n- Permitir que o consumo m\u00e1ximo de energia do servidor seja \u201d<\/p>\n
