Description

Technical Field

[0001] This invention relates to the field of server power management technology, and in particular to a server power current sharing monitoring system, method, device and medium. Background Technology

[0002] With the rapid popularization and expansion of the internet, cloud data centers have been established across various regions, leading to a significant increase in the number and scale of servers in these centers. To ensure data security, the stability of server power supply is paramount, making the power supply the most crucial power module for servers. Currently, data center servers are typically housed in racks, with multiple servers per rack, resulting in high rack density. Each server is generally powered and operated independently by at least two redundant power supplies. To meet the demands of long-term, uninterrupted server operation and complex front-end data processing, server power supplies require high reliability.

[0003] When a server is powered simultaneously by N+N (N≥1) power supplies, the actual power required for server operation is redundantly supplied by 2N power supplies. Theoretically, each power supply has the same output power; however, in practice, factors such as power supply hardware and dynamic response cause differences in the output current of different power supplies at the same time. This difference is called the current sharing ratio of the power supply. Under stable server power supply conditions, the current sharing ratio is generally good, with a current sharing ratio below 10% for a single power supply under 10%-20% load and below 5% for a single power supply under 20% or more load. Under complex server operating conditions, dynamic current sharing may occur, leading to the loss of server power redundancy, power outages due to overcurrent protection, and server shutdown, posing a security risk to customer data.

[0004] The existing server power supply current sharing monitoring scheme is as follows: Taking a server with 1+1 power supply redundancy as an example, it generally adopts the method of reading the output power of the two power supplies in real time. By installing the ipmitool tool package under the Linux system, the ipmitool raw command is used to issue a command to read the power supply output power information in the power supply register through the BMC. The output power of the two power supplies is read continuously, and the current sharing calculation formula is used to calculate the current sharing degree. This scheme is suitable for static current sharing tests of power supplies with low current sharing degree requirements. Example of ipmitool command: ipmitool raw 0x06 0x52 0x1b 0xb0 / 0xb2 0x020x96, where b0 / b2 are power supply address bits, and 96 is the power supply output power address bit. However, when reading the output power of the two power supplies by issuing ipmitoolraw commands through the BMC, the BMC issues commands one by one. Due to the many factors affecting the system's response time to BMC commands (under light load, the response time can be within 500ms, while under heavy load, the response time is slower, exceeding 3s), the output power data of the two power supplies are not obtained from the same clock, but have a time difference. The accuracy of the current sharing calculated in this way is insufficient, and it cannot accurately assess the dynamic current sharing performance of the server power supply, affecting the safe management of server power supply. Summary of the Invention

[0068] In some embodiments, the first warning module 104 is further configured to:

[0069] Upon receiving an alarm command, the abnormal clock interval is identified and the system awaits manual judgment by test personnel.

[0070] In another embodiment, this embodiment provides yet another server power current sharing monitoring system, introducing a synchronous clock module, a first detection module, a second detection module, and an early warning unit. To facilitate understanding of the present invention, the following example uses a server power supply with 1+1 redundancy. The server is redundantly powered by a first PSU and a second PSU. The server system is powered on, and the system is debugged to the stress condition of dynamic power current sharing. The oscilloscope is powered on and debugged to normal working state. The above parts are described in detail below:

[0071] The synchronization clock module needs to be imported and installed in the server and oscilloscope operating systems. The server and oscilloscope are connected via network cable and can communicate normally. After the server and oscilloscope are powered on, the synchronization clock module will automatically run and complete a self-test of its operating status. Testers can set the operating clock of the server and oscilloscope and view the real-time operating status of the module in the module's operating status self-test window.

[0072] The first testing module consists of one oscilloscope, two differential probe kits, two current gun kits, and two sets of three-phase (live, neutral, and ground) power supply cables. One end of each differential probe kit is connected to the oscilloscope, and the other end supplies power to the server power supply. The two sets of differential probe kits measure the continuous input voltage values ​​of the first and second PSUs of the server power supply. One end of each current gun kit is connected to the oscilloscope, and the other end is clamped to the live wire of the three-phase power supply cable. The two sets of current gun kits measure the continuous input current values ​​of the first and second PSUs of the server power supply. During the test, the first testing module monitors the input voltage and current waveforms of the first and second PSUs of the server power supply in real time. Simultaneously, it discretizes the power input voltage and current waveforms within the same clock range (the clock range is adjustable) into power input voltage and current data labeled with clock information.

[0073] The second detection module consists of one server power supply board, two sets of voltage sensors, and two sets of current sensors. The first and second PSUs of the server power supply are normally plugged into the connectors on the server power supply board to supply power to the server system. One set of voltage sensor and one set of current sensor corresponding to the first and second PSUs are connected in parallel before the current sharing bus of the server power supply board and after the power connector, respectively, to monitor the output voltage and input current data (with clock information marked) of the first and second PSUs in real time.

[0074] The early warning unit needs to be imported and installed in the server and oscilloscope operating systems (the one in the oscilloscope system is the first early warning module, and the one in the server system is the second early warning module). The server and oscilloscope are connected via network cable and can communicate normally. After the server and oscilloscope are powered on, the first and second early warning modules automatically run and complete the module operation status self-test. During the test, the first and second early warning modules receive in real time the input voltage, input current, output voltage, and output current data of the server power supply (first PSU and second PSU), marked with clock information, sent by the first and second detection modules. The early warning unit fits the received input voltage, input current, output voltage, and output current of the first and second PSUs into the input power and output power data of the first and second PSUs, averages the data within the same clock range, and calculates the power supply dynamic current sharing within the set clock range based on the average input power and output power of the first and second PSUs. The early warning unit monitors and issues early warnings according to the power supply dynamic current sharing control specifications and the power supply dynamic current sharing data.

[0075] The working principle of each module of the system of the present invention is explained in detail below:

[0076] The first detection module monitors the input voltage and current waveforms of the first and second PSUs of the server power supply. Simultaneously, it discretizes the waveforms within the same clock range into power input voltage and current data labeled with clock information, and transmits the test data to the early warning unit in the oscilloscope system to complete the power input current sharing calculation. The second detection module monitors the output voltage and output current data of the first and second PSUs of the server power supply, respectively, using voltage and current sensors, and transmits the test data to the early warning unit in the server system to complete the power output current sharing calculation.

[0077] In the specific implementation process, an automatic timed waveform capture and saving function of the oscilloscope is set. The first early warning module calculates the dynamic current sharing of the input power of the first and second PSUs of the server power supply in real time, and performs waveform position positioning on the calculated current sharing data, determining and marking the waveform interval where each current sharing data is located (rising interval T1: the current sharing of the PSU does not exceed 50% within 5ms; stable interval T2: the average current sharing of the PSU in this interval does not exceed 5%, and the instantaneous single-point current sharing does not exceed 15%; drop interval T3: the average current sharing of the PSU in this interval does not exceed 10%, and the instantaneous single-point current sharing does not exceed 15%; as follows). Figure 2 (As shown). For a total load trip interval not exceeding 5ms, the PSU current sharing intensity must meet T1 requirements; for a total load trip interval exceeding 5ms, the PSU current sharing intensity must simultaneously meet T1, T2, and T3 requirements. The second early warning module determines the current sharing intensity data of the server power supply according to the above current sharing intensity determination requirements.

[0078] If the current sharing data of the server power supply detected by the first early warning module is within the required range, the data is archived and no alarm is triggered on the server system side. If the current sharing data of the server power supply detected by the first early warning module exceeds the required range, the first early warning module sends a data verification command to the second early warning module. The second early warning module sends a command to retrieve the current sharing data of the server system power supply output within the same clock interval as the abnormal current sharing data on the oscilloscope system side. The first early warning module performs real-time calculation of the dynamic current sharing of the server power supply PSU1 and PSU2 outputs within the required clock interval and feeds back the calculation result to the second early warning module. If the current sharing of the server system power supply output also exceeds the specification range, the second early warning module lowers the system alarm signal Alert, triggers the power supply dynamic current sharing exceeding specification system alarm log, and records the abnormal clock interval. If the current sharing of the server system power supply output does not exceed the specification range, but differs from the judgment result of the first early warning module, the second early warning module issues an alarm command to the first early warning module, identifies the abnormal clock interval, and awaits manual judgment by the test personnel.

[0079] The server power supply current sharing monitoring system in this embodiment has the following beneficial technical effects: It effectively solves the industry's problems that dynamic current sharing indicators for server power supplies can only control individual power supply units; during the server R&D and verification phase, server power supply current sharing is verified only through discrete output power data with inconsistent clocks to determine static current sharing; and the dynamic current sharing capability of the power supply cannot be accurately and continuously tested or warned. It also effectively solves the problems of server power supplies being arranged inside the chassis, requiring large power supply output current, large-range current guns, and the inability to directly measure continuous power supply output current without compromising server integrity. Furthermore, it effectively solves the problem of server power supplies being arranged inside the chassis and powered via standard C13 or C14 cables, where the power input current cannot be directly measured using a current gun without compromising server integrity.

[0080] It should be noted that each module in the aforementioned server power sharing monitoring system can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in the processor of the computer device in hardware form or independent of it, or they can be stored in the memory of the computer device in software form, so that the processor can call and execute the corresponding operations of each module.

[0082] Step 201: Synchronize the system time of the server and the system time of the oscilloscope using a synchronous clock module;

[0083] Step 202: The first detection module uses an oscilloscope to detect the input current and input voltage data of each power supply in the redundant power supply of the server.

[0084] Step 203 involves the second detection module using sensors to detect the output current and output voltage data of each power supply in the server's redundant power supply.

[0085] Step 204, the first early warning module set in the oscilloscope system performs the following operations: acquire data from the first detection module and the second detection module and perform calculations to obtain the first current sharing data of each power supply, determine whether there is an abnormality in the first current sharing data, and determine the time of occurrence of the abnormality when an abnormality is found;

[0086] Step 205, the second early warning module set in the server system performs the following operations: acquires and records data from the first detection module and the second detection module; acquires the time of the anomaly occurrence from the first early warning module; extracts data from the recorded data at the same time according to the time of the anomaly occurrence and performs calculations to obtain the second average flow rate data; and triggers an alarm in the server system or an alarm in the oscilloscope system according to the second average flow rate data.
