Я хотел бы узнать о передовых методах управления по требованию на основе количества ядер, используемых в Dell PowerEdge 1950 Gen II под управлением Ubuntu 16.04 lts.
PowerEdge 1950 имеет два четырехъядерных процессора Intel Xeon X5363, питание по запросу, включенное в BIOS, и полностью поддерживает IPMI.
Ниже приведены подробности и возможности X5365.
