Um dos m\u00e9todos mais eficazes para aumentar a efici\u00eancia energ\u00e9tica dos modernos data centers e reduzir os custos de sua opera\u00e7\u00e3o s\u00e3o os sistemas de isolamento. Tamb\u00e9m s\u00e3o conhecidos como sistemas de conten\u00e7\u00e3o de corredores frios e quentes. O fato \u00e9 que o principal consumidor de pot\u00eancia excessiva em um data center \u00e9 o sistema de resfriamento. Assim, quanto menor a carga sobre ele (redu\u00e7\u00e3o das contas de eletricidade, distribui\u00e7\u00e3o uniforme da carga, redu\u00e7\u00e3o do desgaste dos sistemas de engenharia), maior a efici\u00eancia energ\u00e9tica (rela\u00e7\u00e3o entre a pot\u00eancia total consumida e a pot\u00eancia \u00fatil (gasta com carga de TI)). <\/p>\n

Essa abordagem se tornou bastante comum. \u00c9 um padr\u00e3o amplamente aceito tanto na pr\u00e1tica global quanto na russa. de data centers<\/a>O que voc\u00ea precisa saber sobre sistemas de isolamento para utiliz\u00e1-los da forma mais eficaz? <\/p>\n

Para come\u00e7ar, \u00e9 importante compreender como, no geral, funciona o sistema de resfriamento. No data center, est\u00e3o localizados arm\u00e1rios de montagem (racks), onde est\u00e1 instalado o equipamento de TI. Esse equipamento necessita de resfriamento constante. Para evitar o superaquecimento, \u00e9 necess\u00e1rio fornecer um fluxo de ar frio \u00e0 porta frontal do arm\u00e1rio e retirar o ar quente que sai pela parte traseira. No entanto, se entre as duas zonas \u2014 a fria e a quente \u2014 n\u00e3o houver uma barreira, ambos os fluxos podem se misturar, reduzindo assim o resfriamento e aumentando a carga sobre os condicionadores de ar.
\nPara evitar a mistura de ar quente e frio, \u00e9 necess\u00e1rio construir um sistema de conten\u00e7\u00e3o de ar.<\/p>\n

\"Sistemas
\n<\/a><\/noindex>
\nPrinc\u00edpio de funcionamento:<\/u> um volume fechado (conten\u00e7\u00e3o) acumula ar frio, evitando que ele se misture com o ar quente, permitindo que os arm\u00e1rios com alta carga recebam quantidade suficiente de frio.<\/p>\n

Localiza\u00e7\u00e3o:<\/u> a conten\u00e7\u00e3o de ar deve estar situada entre duas fileiras de arm\u00e1rios de montagem ou entre uma fileira de arm\u00e1rios e a parede da sala. <\/p>\n

Estrutura:<\/u> todos os lados da conten\u00e7\u00e3o que separam as zonas quentes e frias devem ser isolados com divis\u00f3rias, de modo que o ar frio passe apenas pelo equipamento de TI. <\/p>\n

Requisitos adicionais:<\/u> O cont\u00eainer n\u00e3o deve impedir a instala\u00e7\u00e3o e opera\u00e7\u00e3o de equipamentos de TI, a passagem de comunica\u00e7\u00f5es, o funcionamento de sistemas de monitoramento, ilumina\u00e7\u00e3o e combate a inc\u00eandios, al\u00e9m de ser capaz de se integrar ao sistema de controle de acesso da sala de m\u00e1quinas.
\nCusto: esse \u00e9 um aspecto bastante positivo. Em primeiro lugar, o sistema de cont\u00eaineriza\u00e7\u00e3o n\u00e3o \u00e9, de forma alguma, a parte mais cara de todo o sistema de climatiza\u00e7\u00e3o. Em segundo lugar, ele n\u00e3o requer despesas adicionais de manuten\u00e7\u00e3o no futuro. Em terceiro lugar, ele impacta positivamente na economia, uma vez que a separa\u00e7\u00e3o de fluxos de ar e a elimina\u00e7\u00e3o de pontos de superaquecimento local reduzem e distribuem uniformemente a carga entre os climatizadores. No geral, o efeito econ\u00f4mico depende da escala da sala de m\u00e1quinas e da arquitetura de resfriamento. <\/p>\n

Recomenda\u00e7\u00e3o:<\/u> ao substituir equipamentos de TI por modelos mais potentes, nem sempre \u00e9 necess\u00e1rio atualizar os climatizadores para modelos mais potentes. \u00c0s vezes, basta instalar um sistema de isolamento, o que pode fornecer uma reserva de capacidade de refrigera\u00e7\u00e3o de 5 a 10%.
