Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention will be described in further detail with reference to the accompanying drawings.

It should be noted that, in the embodiments of the present invention, all the expressions "first" and "second" are used to distinguish two entities with the same name but different entities or different parameters, and it is noted that the "first" and "second" are only used for convenience of expression, and should not be construed as limiting the embodiments of the present invention, and the following embodiments are not described one by one.

In view of the above object, a first aspect of the embodiments of the present invention proposes an embodiment of a power supply device for a multi-power plane. Fig. 2 is a schematic diagram of an embodiment of the multi-power plane power supply device of the present invention, and as shown in fig. 2, the multi-power plane power supply device includes the following components:

a plurality of controllers 1;

a power backboard 2, wherein the power backboard 2 comprises a plurality of copper sheet layers 21 which are not connected with each other; and

a plurality of PSU power packs 3, each PSU power pack 3 being configured to power a first number of said controllers 1, each PSU power pack 3 comprising a plurality of PSU power supplies 31, each PSU power supply 31 being arranged in a separate power plane 32, the PSU power supply in each power plane 32 being connected to said first number of said controllers 1 by a copper skin 21.

In fig. 2, two PSU power supply groups 3 are illustrated, each power supply group 3 comprising two PSU power supplies. PSU0 and PSU1 in the first PSU power supply group are not combined on the power supply backboard 2, PSU0 and PSU1 are respectively located on different power supply planes to supply power to the controller 0 and the controller 1, and PSU2 and PSU3 also respectively supply power to the controller 2 and the controller 3; the difference between the power supply and the N+N redundant power supply in the prior art is that the N+N redundant power supply in the prior art can only prevent the power supply from malfunctioning, namely, when one power supply malfunctions, other power supplies can supply power, but the power supplies in the prior art are all positioned on a power supply plane, and when the power supply plane is abnormal, the powered equipment of the whole plane cannot work. Each PSU in the embodiment of the invention has the capability of independently supplying power to two controllers and the IO card thereof, namely, any one of PSU0 and PSU1 is supplied with power, and the controller 0 and the controller 1 can work normally, thereby realizing the 1+1 redundancy of PSU. Therefore, the high reliability and usability of the power supply system of the storage product are realized through the optimal design scheme of the true biplane double-redundancy AC power supply, and the market competitiveness of the product is further improved.

In the embodiment of the invention, an AC power supply plane segmentation mode is adopted to segment a power supply plane of a storage product into four independent planes, a first power supply plane formed by PSU0 and a second power supply plane formed by PSU1 supply power to the controller 0 and the controller 1, a third power supply plane formed by PSU2 and a fourth power supply plane formed by PSU3 supply power to the controller 2 and the controller 3, and each powered device has two planes for supplying power, and if one of the power supply planes is short-circuited or other faults can not affect the normal power supply function of the other plane. Secondly, a single planar PSU has independent power supply capability, that is, the PSU power supply of each planar PSU has enough power supply capability to support all boards of the planar PSU to work normally, so that 1+1 redundant power supply capability is provided for all powered devices.

In some embodiments, the controllers of the PSU power connections of the same PSU power pack are the same. In this embodiment, the controllers of the PSU power connections of the same PSU power group are the same. That is, the PSU0 and PSU1 belonging to the same PSU power group are connected to the same controller, and both the controller 0 and the controller 1 are connected to each other; the PSU2 and PSU3 belonging to the same PSU power supply group are connected to the same controller, and both the controllers 2 and 3 are connected. This may facilitate the user's understanding of the connection of the PSU power supply to the controller.

In some embodiments, the controllers of the PSU power connections of the same PSU power group may be different. For example, the controllers to which PSU0 and PSU1 belonging to the same PSU power supply group are connected may be different, PSU0 may be connected to controller 0 and controller 1, PSU1 may be connected to controller 2 and controller 3, likewise, PSU2 and PSU3 belonging to the same PSU power supply group may be connected to different controllers, PSU2 may be connected to controller 0 and controller 1, and PSU3 may be connected to controller 2 and controller 3. Although the controllers of the PSU power supply connection of the same PSU power supply group may be different, it is still required to satisfy that each controller is connected to at least two power supply planes, so as to avoid that the controller cannot operate after an abnormality occurs in one power supply plane.

In some embodiments, different PSU power groups contain different numbers of said PSU power sources. For example, the PSU power supplies of the first PSU power supply group may be two, and the PSU power supplies of the second PSU power supply group may be three, i.e. the number of PSU power supplies in each PSU power supply group may be different. Since the power supply capacity of each PSU power supply is uniform, the number of controllers to which the PSU power supply group is connected may be determined according to the number of PSU power supplies in each PSU power supply group, that is, if the number of PSU power supplies in the PSU power supply group is 2, the number of controllers to which the PSU power supply group is connected is also 2, and the number of controllers to which each PSU power supply in the PSU power supply group is also 2. Of course, if PSU power supplies of different power supply capacities are employed, the number of connected controllers may be determined according to the actual power supply capacity of the PSU power supply.

In some embodiments, the number of PSU power supplies of each PSU power supply group is greater than or equal to the first number. In order to achieve a redundant function of power supplies, i.e. each PSU power supply is capable of powering all connected powered devices, the number of controllers is required to be less than or equal to the number of PSU power supplies in the PSU power supply group. For example, two PSU power supplies are included in a PSU power supply group, and the number of controllers to which the PSU power supply group is connected is at most 2. However, if the power supply capability of a single PSU power supply is able to meet the requirements of three controllers, the number of limitations may be moderately relaxed.

In some embodiments, the controller further comprises a BBU power supply, the controller outputting the BBU power after combining the BBU power supply with the PSU power supply. Each controller is connected with a plurality of IO cards, and the corresponding IO cards are powered through the controllers, so that the corresponding IO cards do not get electricity at the power backboard, but get electricity through the attributed controller, and the IO cards and the controllers can work simultaneously. Meanwhile, the controller outputs the current provided by the BBU power supply or the PSU power supply through the same channel, namely, the BBU power supply and the PSU power supply are combined on the controller and then power is supplied to the IO cards, so that a combining chip on each IO card is omitted, and only one-time combination is performed on the controller.

And respectively taking power from all controllers for public modules such as the management board and the like, and combining the power in the management board. As shown in fig. 2, the management board 0 and the management board 1 are respectively combined in the management board after power is taken from the four controllers, so that the management board can work normally as long as one controller is normal, that is, as long as one PSU is powered normally. Therefore, the public modules such as the management board and the like can be combined in the management board after power is taken from each controller, so that the management board can work normally even if only one PSU power supply is normal.

The invention adopts an AC power plane segmentation mode to segment the power plane of the storage product into a plurality of independent planes, each powered device has at least two planes for power supply, and if one power plane is short-circuited or other faults can not affect the normal power supply function of the other plane. And, single plane PSU has independent power supply ability, namely the PSU power of each plane has sufficient power supply ability to support the normal work of all integrated circuit boards of this plane, has like this to all power receiving equipment has 1+1 redundant power supply ability. There are several advantages to the present invention:

(1) The AC power plane is divided, each powered device is provided with two independent planes for independent power supply, and the normal power supply function of the other plane is not affected by the fault of one plane;

(2) PSU power supply redundancy in the PSU power supply group, wherein one PSU power supply fails and the corresponding powered equipment works normally;

(4) And the common modules such as the management board and the like are respectively combined in the management board after power is taken from the controllers, so that the common modules can work normally as long as one controller is normal.

In view of the above object, a second aspect of the embodiments of the present invention proposes an embodiment of a server. The server comprises a multi-power plane power supply device. The power supply device of the multi-power plane comprises: a plurality of controllers; the power supply backboard comprises a plurality of copper sheet layers which are not connected with each other; and a plurality of PSU power packs, each PSU power pack configured to power a first number of said controllers, each PSU power pack comprising a plurality of PSU power supplies, each PSU power supply being disposed in a separate power plane, the PSU power supplies in each power plane being connected to said first number of controllers by a copper layer.
