RACK AND POWER CONTROL METHOD THEREOF

摘要

A power control method of a rack having a plurality of nodes includes the following steps. Power information of each node is received. a total power consumption value of the plurality of nodes according to the power information is calculated. A number of power supply units to be turned on according to the total power consumption value and a maximum supplied power value of a single power supply unit is calculated. At least one primary power supply unit and at least one secondary power supply unit in pairs according to the number of power supply units to be turned on is started. The at least one primary power supply unit provides a duty voltage to the plurality of nodes, and the at least one secondary power supply unit does not provide the duty voltage to the plurality of nodes.
