Multi-power-plane power supply device and a serve

Abstract

The invention discloses a multi-power-plane power supply device and a server. The device comprises a plurality of controllers; a power supply backboard which a plurality of copper sheet layers which are not connected with each other; and a plurality of PSU power supply groups, wherein each PSU power supply group is configured to supply power to a first number of the controllers, each PSU power supply group comprises a plurality of PSU power supplies, each PSU power supply is arranged on an independent power supply plane, and the PSU power supply in each power supply plane is connected with the first number of the controllers through a copper sheet layer. Each power receiving equipment is provided with more than two power supply planes for independent power supply, normal power of the other plane is not affected when one plane fails, one PSU power supply group comprises a plurality of PSU power supplies, and the corresponding power receiving equipment can work normally when one PSU power supply fails.

Description

technical field [0001] The present invention relates to the field of servers, and more particularly, to a power supply device with multiple power planes and a server. Background technique [0002] Although the existing storage product AC (Alternating Current, alternating current) power supply implements dual-plane power supply, it only physically divides the entire system into two parts, and then configures a power domain for each part. In fact, for a powered device behind a board, it is essentially a single power supply plane, such as figure 1 As shown, the first power domain composed of PSU0 and PSU1 supplies power to controller 0 and controller 1, while the second power domain composed of PSU2 and PSU3 supplies power to controller 2 and controller 3, that is, PSU2 and PSU3. The second power domain does not supply power to controller 0 and controller 1, so there is a shortage. Although it is N+N power redundancy, if one of the power domains fails, all the cards or powered...

Problems solved by technology

In fact, for the electrical equipment behind a certain board, it is essentially a single power plane for power supply, such as figure 1 As shown, the first power domain composed of PSU0 and PSU1 supplies power to controller 0 and controller 1, and the second power domain composed of PSU2 and PSU3 supplies power to controller 2 and controller 3, which is composed of PSU2 and PSU3 The second power domain does not supply power to controller 0 and controller 1, so there will be a deficiency. Although it is N+N power supply redundancy, if one of the power domains fails, all boards or powered devices in this domain cannot work as figure 1 As shown, if the first power domain fails, the controller 0 and controller 1 powered by the first power domain and their IO (input output) cards cannot work normally, which will inevitably lead to the degradation of the services provided by the equipment.
