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...
