Rack and power controlling method thereof

摘要

The disclosure provides a rack, including nodes and power supplies, and a power controlling method thereof, including the following steps. Power information of each node is collected to calculate a total power consumption value of the nodes. A power supply enabling demand is calculated according to the total power consumption value and a maximum power supply value of the power supply. State information of each of the power supplies is read to obtain a first sequence of the power supplies. According to the power supply enabling demand and the first sequence, two of the power supplies are enabled and set as a master power supply and a secondary power supply, and the rest of the power supplies are disabled. While the master power supply provides a work voltage to the nodes, the secondary power supply does not supply the work voltage to the nodes.

主权项

1. A power controlling method for a rack comprising a plurality of nodes and a plurality of power supplies, comprising:
receiving power information of each of the nodes to calculate a total power consumption value of the nodes; calculating a power supply enabling demand according to the total power consumption value and a maximum power supply value of the power supply; reading state information of each of the power supplies to obtain a first sequence of the power supplies; enabling at least two of the power supplies according to the power supply enabling demand and the first sequence, setting the enabled power supplies as at least one current master power supply and at least one current secondary power supply, and disabling the rest of the power supplies; reading the state information of the rest of the power supplies in a preset period to obtain a second sequence of the rest of the power supplies; enabling at least two of the rest of the power supplies according to the power supply enabling demand and the second sequence, and setting the enabled power supplies as at least one new master power supply and at least one new secondary power supply; disabling the at least one current master power supply and the at least one current secondary power supply; determining whether the nodes stop operating; and when the nodes do not stop operating, returning to the step of reading the state information of the rest of the power supplies in the preset period to obtain the second sequence of the rest of the power supplies, wherein while the at least one current master power supply provides at least one work voltage to the nodes, the at least one current secondary power supply and the rest of the power supplies do not supply the at least one work voltage to the nodes.
