Измерение мощности и эффективности в «зеленых» ЦОД

На протяжении нескольких лет растущая потребность в питании и охлаждении остается едва ли не главной заботой владельцев ЦОД. Причина тому – огромный спрос на вычислительную мощность и увеличение плотности устройств. Одновременно набирает силу тенденция перехода на модульные серверы. В результате усугубляются проблемы с охлаждением, поскольку чем больше мощность, тем больше выделяемое тепло...

Противостояние шины и кабеля

При выборе решения для энергоснабжения ЦОД необходимо принимать во внимание не только экономические факторы, но и особенности помещения: низкие потолки, плотно стоящие стойки или конструкцию двойного пола. Сегодня электрораспределительные системы на базе шин применяются как альтернатива кабельным решениям и в некоторых средах даже их вытесняют....

Качественный кабель помогает экономить электроэнергию

Применение в центре обработки данных высококачественной информационной кабельной системы является одним из важнейших условий экономии электроэнергии, затрачиваемой на питание и охлаждение. Кроме того, такая проводка делает излишним использование сложных схем компенсации шумов, что дополнительно снижает уровень энергопотребления...

Экономика ИБП

Применение в ЦОД энергоэффективных ИБП помогает снизить потребление электроэнергии, при этом мощность и надежность источников бесперебойного питания остаются неизменными. ...
