FIG. 1 is a block diagram illustrating an embodiment of a server rack of the present invention.
[ detailed description ] of the invention
Referring to fig. 1, the server cabinet of the present invention includes a plurality of servers 1, 2, each server 1, 2 including a power management unit (Power management unit, PMU) 12, 22, an application circuit 13, 23, and a baseboard management controller (Baseboard management controller, BMC) 11, 21. Either of the servers 1, 2 may also be a Node (Node) in the server rack.
Each of the power management units 12, 22 is, for example, a Linear regulator (Linear regulator), receives a dc input voltage to convert the dc input voltage into a dc output voltage, and the dc output voltage corresponds to a dc output current, so as to be used as a dc output power source. Each dc input voltage is provided by one or more power supplies (not shown) further included in the server rack, for example, the at least one power supply is in compliance with the ATX standard, so as to convert the ac voltage of the utility power into a power voltage including at least one dc input voltage, for example, but not limited to, 12 v, 5 v, and 3.3 v. Of particular emphasis is the description: the foregoing power management units 12 and 22 each receive a dc input voltage to convert the dc input voltage to output a dc output voltage, and the dc output voltage corresponds to a dc output current, which does not mean that each power management unit 12 and 22 only receives one dc input voltage to output a corresponding dc output voltage, but means that when each power management unit 12 and 22 receives one dc input voltage, one dc output voltage is output, and when receiving three dc input voltages (e.g. 12, 5, 3.3 volts), three dc output voltages are output, respectively.
Each application circuit 13, 23 is electrically connected to the corresponding power management unit 12, 22 to receive the dc output voltage as a power source for operation, i.e. the dc output power source is used as a power source for operation. Either of the application circuits 13, 23 is at least one electronic component included in the corresponding server 1, 2, for example, the application circuit 13 includes at least one of a Central Processing Unit (CPU), a Chipset (Chipset), and a graphics card (graphics card).
Each baseboard management controller 11, 21 is electrically connected to the corresponding power management unit 12, 22 to receive a power management information of the power management unit 12, 22. In this embodiment, each of the power management information includes at least one of the corresponding dc output voltage, the corresponding dc output current, and an operation information of the corresponding application circuit. The operation information includes at least one of an operation voltage, an operation current, an operation power consumption, an operation temperature and an operation state provided to the corresponding application circuit 13, 23 by the power management unit 12, 22, i.e. the actual operation information of the application circuit 13, 23, wherein the baseboard management controller 11 further calculates a server power consumption of the corresponding server 1, 2 according to the received power management information, and records the server power consumption in the power management information.
For convenience of explanation, the number of servers 1, 2 is two. The baseboard management controllers 11, 21 are electrically connected to each other, for example, by a network chip (not shown) included in the corresponding server 1, 2, and one of the baseboard management controllers 11, 21 operates in a Master mode, and the other baseboard management controller 11, 21 operates in a Slave mode, for example, the baseboard management controller 11 and the baseboard management controller 21 operate in the Master mode and the Slave mode, respectively.
Each baseboard management controller 21 operating in the slave mode transmits the corresponding power management information to the baseboard management controller 11 operating in the master mode, i.e., the baseboard management controller 21 transmits the corresponding power management information to the baseboard management controller 11.
The baseboard management controller 11 operating in the master mode is further electrically connected to the power management unit 22 corresponding to the baseboard management controller 12 operating in the slave mode, and controls the power management units 12 and 22 to perform power management according to the power management information received and corresponding to the baseboard management controller. In more detail, the baseboard management controller 11 operating in the master mode controls the corresponding power management units 12 and 22 not to output the dc output voltage, i.e. not to output the corresponding dc output current, when determining that the corresponding power management units 12 and 22 are overloaded according to each power management information and a corresponding preset first overload warning point. For example, the first overload warning point is a preset current value, and when the magnitude of the dc output current of the power management information of the power management unit 12 exceeds the preset current value, the baseboard management controller 11 controls the power management unit 22 not to output the dc output voltage, that is, not to output the corresponding dc output current, so as to avoid the overload condition.
In addition, each baseboard management controller 11, 21 is electrically connected to the corresponding application circuit 13, 23, respectively, to receive a corresponding operation information including at least one of an operation voltage, an operation current, and an operation temperature detected by the application circuit 13, 23.
Each baseboard management controller 11, 21 also controls the corresponding power management unit 12, 22 and the corresponding application circuit 13, 23 to perform power management according to the received operation information. In more detail, each baseboard management controller 11, 12 controls the corresponding application circuit 13, 23 to change the operation mode when judging that the corresponding application circuit 13, 23 is overloaded according to each operation information and a corresponding preset second overload warning point. To be particularly supplementary stated are: the second overload warning point according to which each baseboard management controller 11, 12 is based may be different according to the application circuit 13, 23, and may have different values. In addition, when the dc output voltage received by each application circuit 13, 23 from the corresponding power management unit 12, 22 can be divided into a plurality of power circuits, the power circuits can also respectively have a plurality of corresponding same or different second overload warning points.
For example, the second overload warning point is a preset temperature value, and when the operating temperature of the operation information of the application circuit 13 exceeds the preset temperature value, the baseboard management controller 11 controls the application circuit 13, such as a display chip, to operate in a power saving mode. Alternatively, the second overload warning point is a preset power consumption value, and when the operation power consumption of the operation information of the application circuit 23 is higher than the preset power consumption value, the baseboard management controller 21 controls the application circuit 23, for example, a cpu, to operate in a down-conversion mode.
In addition, the following are to be specified: the power management units 12, 22 of each server 1, 2 and the power supply (not shown) of the server rack may include respective overload protection circuits to monitor the corresponding dc output voltage or the corresponding dc output current. The overload protection circuit is to avoid hardware damage caused by overload of the application circuit 13, 23, and the overload indicated by the first overload warning point and the second overload warning point of the present invention means that the operation current consumed by the application circuit 13, 23 or the received operation voltage has deviated from a predetermined range originally arranged or designed, and appropriate power management is performed by the baseboard management controller 11, 21.
In addition, a User or manager can control the baseboard management controller 11 operating in the master mode through a User interface (User interface) via a network to monitor the operation of the application circuits 13, 23 through the power management units 12, 22, and can update the first overload warning point and the second overload warning point.
In summary, the baseboard management controller operating in the master mode obtains the power management information of all the power management units and the operation information of the application circuit through the other baseboard management controllers operating in the slave mode, and determines the power supply condition of the corresponding power management unit and the operation condition of the application circuit according to at least one of the power management information and the operation information, thereby controlling the power management unit and the application circuit, so as to achieve the purpose of the invention.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
