Description
Technical Field
The present invention relates to the field of servers, and in particular, to a method, a system, a computer device, and a readable medium for power source current sharing of a server.
Background
LinkedIn OPEN19 proposes a suite of OPEN server standards aimed at increasing the density of 19 inch (now mainstream server standard size) data center rack servers and storage, and network related equipment, reducing the cost of rack equipment, optimizing rack integration and deployment, optimizing power utilization, and ultimately providing a low cost infrastructure solution for data centers in different environments.
Since the power racks are universal, any power source, alternating current, direct current, single phase or multi-phase, all is sent to the power racks and distributed to the system, the servers are unaware of their environment. Open19 uses decentralized hardware with complete power isolation between servers. The rack is not provided with a shared bus; each server is fully protected, monitored and enabled by a separate channel. The power supply channel is isolated, and each server is protected by an e-fuse. The single e-fuse also provides real-time power consumption data, which may reveal emerging hardware problems. This often means a problem if one sees a fluctuation in power consumption of one server. There may be many writes in memory or the disk drive is not executing. Thermal fluctuations can also be tracked and network failures or problems with load balancers can be seen.
The Power Shelf may use a group of 3.2kW Power supplies with a maximum Power setting of 5+1, so a maximum of 16kW output is provided, each output having a group of e-fuses to protect the servers and switch Power supplies in the Power Shelf, and the current limit for the e-fuses is set at 35A. Because e-fuse in Power Shelf has a limit of 35A, 1 set is 400W, and the output of the parallel 4 sets of efuses is 1600W at most, the Power density of the current server is higher and higher, and the application of the GPU is increasing in recent years, the short-time high peak Power demand characteristic of the GPU is undoubtedly a great challenge to the current OPEN19, and the application of 1600W is completely insufficient and needs to be processed in an additional way to meet the requirement.

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 are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
In view of the foregoing, a first aspect of the embodiments of the present invention provides an embodiment of a method for power source current sharing of a server. Fig. 1 is a schematic diagram illustrating an embodiment of a method for power source current sharing of a server according to the present invention. As shown in fig. 1, the embodiment of the present invention includes the following steps:
s1, supplying power to the server by adopting a first power supply with a first quantity of first reference power and a second power supply with a second quantity of second reference power, and connecting the first power supply and the second power supply;
s2, calculating the average current values of all power supplies based on the total load power, making the current value in each power supply be the average current value, and obtaining the output voltage value corresponding to each power supply based on the average current value;
s3, responding to the change of the total load power, calculating a new output voltage value corresponding to each power supply and judging whether the new output voltage value exceeds a preset threshold value or not; and
and S4, responding to the new output voltage value not exceeding the preset threshold value, and adjusting the output voltage value of the power supply to be the new output voltage value.
The embodiment of the invention aims at the problem that a 19-inch server cannot adopt a plurality of groups of power supplies for power supply and control current sharing. The existing server usually has only one power socket window, and in order to be powered by multiple groups of power supplies, a plurality of power socket windows can be arranged on the shell. Because the power racks are not communicated with each other, the voltage difference cannot be controlled, and therefore current sharing cannot be carried out on the multiple groups of power supplies. The Ishare (average) signals of the two power racks can be connected by cables, so that the two power racks can share the same current. Holes can be dug on the power supply racks, terminals are newly added, and Ishare is connected to the newly added terminals, so that current sharing among multiple groups of power supply racks can be realized.
And adopting a first power supply with a first quantity of first reference power and a second power supply with a second quantity of second reference power to supply power for the server, and connecting the first power supply and the second power supply. In general, the power supplies with the same reference power can be adopted to supply power to the server, so that the current sharing is controlled conveniently. In order to make the adaptability of the server stronger, power supplies with different reference powers can be adopted to supply power to the server. The first number and the second number may be the same or different, and the first reference power and the second reference power may be the same or different. For example, 3 power supplies with reference power of 2000w and 1 power supply with reference power of 1000w can be used to supply power to the server. Connecting the first power supply and the second power supply can solve the problem of power supply isolation.
And calculating the average current value of all power supplies based on the total load power, enabling the current value in each power supply to be the average current value, and obtaining the output voltage value corresponding to each power supply based on the average current value.
In some embodiments, the calculating an average current value for all power sources based on total load power and such that the current value in each power source is the average current value comprises: and obtaining a total current value according to the total load power and the reference voltage, and obtaining an average current value according to the total current value and the number of the power supplies. For example, the total load power is 4000W, the reference voltage is 12V, the total current value is the ratio of the total load power to the reference voltage, that is, 4000W/12V is 333.33A, the number of power supplies is 3+1 is 4, and the average current value is the ratio of the total current value to the number of power supplies, that is, 333.33A/4 is 83.33A.
In some embodiments, the deriving the output voltage value corresponding to each power supply based on the average current value includes: and obtaining a reference current value according to the reference power of the power supply and the reference voltage, and obtaining an output voltage value according to the ratio of the average current value to the reference current value. For example, a reference current value is obtained from a reference power of a power supply and the reference voltage, a reference current value of a 1000W power supply is 83.33A/12V, and an output voltage value is obtained from a ratio of an average current value and the reference current value, and if the total power is full at 8V, the output voltage value is 83.33A/8V or 8V, and similarly, a reference current value of a 2000W power supply is 2000W/12V 166.67a and the output voltage value is 83.33/166.67 a/8V or 4V.
Responding to the change of the total load power, calculating a new output voltage value corresponding to each power supply and judging whether the new output voltage value exceeds a threshold value or not; and adjusting the output voltage value of the power supply to the new output voltage value in response to the new output voltage value not exceeding the threshold. For example, when the total load power is 4800W, the output voltage of the 1000W power supply is 100A/83.3A × 8V — 9.6V, the output voltage of the 2000W power supply is 100A/166.7 × 8 — 4.8V, and the output voltage value can be adjusted from the original 8V and 4V to 9.6V and 4.8V; if the total load power rises to 6000W, the output voltage value of the 1000W power supply already exceeds the threshold value of 9.6V, i.e., the power supply is not adjusted, the output voltage value of the 2000W power supply is 133.3A/166.7A × 8V — 6.4V, and the output voltage value of the 2000W power supply can be adjusted to 6.4V.
In some embodiments, the calculating an average current value for all power sources based on total load power and such that the current value in each power source is the average current value comprises: and inputting the current value of each power supply into an operational amplifier, and increasing the voltage of the power supply corresponding to the current value in response to the operational amplifier detecting that the current value is lower than the average current value. Since a larger voltage can be obtained to obtain a larger current, the current can be adjusted by adjusting the voltage.
In some embodiments, the method further comprises: and judging whether the current voltage value of each power supply is normal or not based on the average voltage value, and adjusting the current voltage value of each power supply according to the average voltage value in response to the fact that the current voltage value of each power supply is abnormal.
In some embodiments, the determining whether the current voltage value of each power supply is normal based on the average voltage value includes: and outputting the voltage value of each power supply to a current-sharing bus, and calculating the average voltage value.
In some embodiments, said adjusting the current voltage value of the power supply according to the average voltage value comprises: in response to a present voltage value being lower than the average voltage value, boosting the present voltage value to the average voltage value.
It should be particularly noted that, the steps in the embodiments of the server power supply current sharing method described above may be mutually intersected, replaced, added, or deleted, and therefore, the method for server power supply current sharing, which is transformed by these reasonable permutations and combinations, shall also belong to the scope of the present invention, and shall not limit the scope of the present invention to the embodiments.
