Detailed Description
The application has the core of providing a server power supply black box data analysis system, which can directly analyze the server power supply black box data on site, does not need to analyze through BMC and IPMI tools, does not need to be electrified and an additional jig board card, can greatly reduce RCA time and discover the problem of off-line of a large-scale system as soon as possible, and can return to work without returning to the original factory after the server power supply is analyzed by the device provided by the application, thereby saving service and maintenance cost.
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In order to facilitate understanding of the solution of the present application, the following describes server power black box data, and from the perspective of power management, parameters such as voltage, current, temperature or fan speed need to be monitored in the operation process of the server system, and the main functions of the BMC are to control and monitor a large number of power supplies and fans, including: system failure queries, such as: whether the overvoltage/undervoltage, overcurrent and temperature exceed the working range or not or whether the fan speed is normal or not converts fault monitoring into simple operation of detecting whether the parameters exceed the threshold value or not. Data is thus collected in real time during operation of the server power supply and stored in the EEPROM upon failure, thereby creating an event data recorder, similar to a "black box" on board an aircraft, which will collect a large amount of up-to-date data (e.g., up-to-date data within 20 ms) at preset periods. When the server system fails, the instant information of the server system is permanently recorded so as to be capable of checking the system operation in the period of 10ms to 20ms before the failure occurs later, and a data basis is provided for checking the cause of the system failure and analyzing the power failure. By checking this data, the time period can be reorganized and the interdependence of the system and the power supply can be determined. In an ideal situation, the complex server power black box data records multiple faults, so that interdependencies among systems are convenient to build, and after one fault occurs, more subsequent faults can be possibly caused. In order to find the root cause of the fault, therefore, a recorder is required to record as complete data as possible.
It will be appreciated that although binary or decimal values may be readily represented, stored and transmitted, they may be represented as holes or no holes in a punched card, high or low voltages on wires, or clockwise or counter-clockwise magnetic fields, for example. The electronic circuits that store and perform calculations on binary signals are very simple and reliable, and manufacturers can integrate millions or even billions of such circuits on a single chip. Currently, most computers use 8-bit blocks (bytes) as the smallest addressable unit of memory. One byte consists of 8 bits, and is represented by binary values in the range 0000 0000 to 1111 1111 and decimal values in the range 0 to 255. It can be seen that binary representation is too lengthy and the mutual conversion of decimal representation and bit pattern is cumbersome, while hexadecimal represents the 16 values 0-15 with the digits 0-9 and the characters a-F, the conversion between hexadecimal and binary is simpler and more straightforward, therefore, one byte is usually represented in hexadecimal, its value range is 00-FF.
Hexadecimal saves more bytes than two-level system under the same EEPROM capacity. Taking hexadecimal may store a greater amount of data than binary or decimal. Also, hexadecimal is mainly used in the C language, and a numerical constant beginning with 0X or 0X is considered to be a hexadecimal value, such as given a hexadecimal representation of a number: 0x173A4C, and vice versa, if a binary number is given, it can be converted to hexadecimal by dividing it into groups of 4 bits, and it should be noted that if the total number of bits is not a multiple of 4, the leftmost group can be less than 4 bits, and the front is padded with 0, so in the prior art, the server power black box stores the parameter information and state of the server power using hexadecimal format, so as to save more bytes, but it is difficult for a person to directly read the data of hexadecimal number.
The following describes a data analysis system of a server power supply black box in detail.

specifically, the PCB (Printed Circuit Board ) of the dongle 1 includes an I2C (Inter-Integrated Circuit, integrated circuit bus) signal hole site designed to be led out by a wire to be connected to the input interface 11, and the input interface 11 is connected to a server power source for obtaining server power source black box data, where the server power source black box data is original hexadecimal data, including but not limited to input current, input voltage, output voltage, input power, output power, fan speed and temperature.
The controller 12 is configured to parse the server power black box data according to a preset linear format to obtain prompt data, where the format of the prompt data is a decimal format;
specifically, the controller 12 needs to support the I2C communication protocol, the USB (Universal Serial Bus ) communication protocol, the firmware encoding principle, and the PMBus1.2 specification, i.e. the content and format of the transmission need to be in accordance with the PMBus1.2 specification, and the application level of 3.3V voltage needs to be satisfied, and the working clock is in the range of 100KHz to 400 KHz. Specifically, firmware in the controller 12 also accords with pmbus1.2 specification, hardware of the controller 12 retrieves server power black box data from a server power supply, and then the server power black box data is parsed by the firmware of the controller 12, wherein different types of server power black box data are stored in different registers according to pmbus1.2 specification, such as input current is stored in a first register, output voltage is stored in a second register, and so on. When analyzing, firstly judging whether server power black box data exist in each register, taking out the server power black box data in the register with the data, analyzing to obtain decimal format prompting data, wherein the analyzing process is as follows:
for data such as input current, input voltage, input power, output power, fan speed, and temperature, the first relation x=yx2 is adopted N Analysis is performed, wherein x=y×2 N The Linear-11 data format uses (N) a 5-bit two-level complement exponent and (Y) an 11-bit two-level complement mantissa for the analytical relation provided by PMBus1.2 for all sensor detection values of Linear-11, X is the hint data, and an example of the calculation is shown in FIG. 2.
For the output voltage, according to the second relation x=yx2 -9 By way of analysis, it can be appreciated that the voltage value is represented using the fixed high Linear-11,9 bit indication of the vout_mode register of the PMBus register, thus fixing n= -9h.
An output interface 13 connected with the prompting device 2, for transmitting prompting data to the prompting device 2 so that the prompting device 2 prompts the prompting data;
specifically, the output interface 13 adopts Mini-USB A type, and is connected with the prompting device 2 through a transmission line, the transmission line adopts standard Mini-USB A type to USB 2.0 wires, USB 2.0 signals, D+ and D-, ID are led into the controller 12 for processing, the power supply VCC (+5V) is connected into a 5V-to-3.3V power supply circuit, GND pulls in all parts and reference signals, and prompting data is transmitted to the prompting device 2, so that the prompting device 2 prompts. As a preferred embodiment, for portability, the prompting device 2 may select a mobile terminal with graphical interface software to prompt the prompting data through the graphical interface software on the mobile terminal. Of course, besides the notebook, other mobile terminals including tablet computers can be selected, and the application is not described herein.
In particular, a notebook computer with a GUI (Graphical User Interface ) may be employed. The GUI is a graphical operation interface, and can be programmed by special software, such as LabVIEW software, and applied to an execution file of a notebook computer, and its man-machine interface function can select a server power address, a working clock, etc., when connection is executed, that is, a PMBus instruction is executed on a server power, the server power black box data in the problem log is loaded, and decimal prompt data analyzed by the dongle 1 is loaded as interpretation, and a schematic diagram of the prompt interface is shown in fig. 3.
As a preferred embodiment, the prompting device 2 is further used for checking the dongle 1;
correspondingly, the process for prompting the prompting data comprises the following steps:
and prompting the prompting data when the verification is successful.
Specifically, considering that the analysis content and the parameters have secret information, in order to improve the safety of data interaction, the verification function of the graphical interface software can be utilized to verify the dongle, after the verification is successful, decimal data analyzed by the dongle 1 is prompted, meanwhile, the verification function of the dongle 1 is matched, data acquired from a server power supply is verified, and after the verification is successful, analysis is performed.
Specifically, the verification process is as follows: the dongle 1 performs data interaction with the MCU of the server power supply, and transmits a verification password, the MCU confirms that the dongle 1 is a legal element, the data stored in the EEPROM is transmitted to the dongle 1 for analysis, after analysis is completed, the dongle 1 transmits an identification password to a computer for identification communication with a graphical operation interface, and after the computer confirms that the dongle 1 is the legal element, the computer transmits the decimal data interpreted by the dongle to the graphical operation interface for display.
The special software programming elements need to be: the element for executing the I2C instruction, considering that I2C has address selecting and EEPROM reading actions, is used for reading the EEPROM, and in order to realize the function of the dongle verification, the dongle reading verification element is needed. All the important elements are connected and grouped to complete the graphic operation interface to execute the function of reading and prompting the data of the server power supply black box, and the data can be executed on a computer after programming.
A power module 14 for powering the controller 12.
Specifically, the power module 14 is a 5V to 3.3V converter, which is mainly supplied to the controller 12 and is required for power supply for signal transmission. In order to save the whole space and the manufacturing cost, the embodiment can adopt a surface mount technology packaged converter.
Specifically, the power supply module is a linear LDO (Low Dropout Regulator, low dropout linear regulator), the working principle of the LDO is to regulate the output of the P-MOS through the op-amp, generate a reference voltage inside the LDO as the reverse voltage of the op-amp, and use the output voltage of the LDO as the forward input voltage of the op-amp through voltage division. The output of the operational amplifier controls the working state of the P-MOS transistor, and the P-MOS transistor is in a linear resistance region and can be regarded as a voltage-controlled variable resistor. The input voltage VIN becomes the output voltage after passing through the P-MOS transistor, where the P-MOS transistor functions to dynamically attenuate the input voltage by passing through the linear resistive region of the P-MOS transistor, so that a large amount of heat is collected in the P-MOS transistor, and the processing power is generally less than 1.5W. This is different from a switching power supply, which is composed of a Pulse Width Modulation (PWM) control IC, a MOSFET, a magnetic element, and a capacitor. With the development and innovation of power electronics technology, the present switching power supply is widely applied mainly with the characteristics of small size, light weight and high efficiency. The switching MOS tube used by the switching power supply is mostly switched between a full-open mode (saturated region) and a full-closed mode (cut-off region), the two modes have the characteristic of low dissipation, and the switching between the two modes has higher dissipation, but the switching time is short, so that the energy is saved, and the waste heat is less. However, the switching power supply is complex, the MOS transistor is frequently switched, noise and electromagnetic interference may be generated to affect other devices if the switching current is not processed, and if the switching power supply is specially designed, the power factor of the switching power supply is high, and the processing power of the switching power supply is usually hundreds.
Therefore, in this embodiment, the BMC firmware in the server system is not required to add a black box parsing function, so that the server can return to the line after replacing the fault power supply. The power-on and extra jig board card is not needed, and the power-off can be analyzed, so that the secondary damage of the power supply is avoided. The server power supply is not required to be returned to the original power supply factory for analysis, the software dog can directly analyze the data of the server power supply black box on site, the operation is simple, and the analysis of the data of the power supply black box can be performed without setting a key too much. The decimal data which is convenient for the user to interpret is obtained, and then the decimal data is prompted through the prompting device, so that the user can directly obtain the parameter information and the state of the server power supply according to the decimal data, the RCA time is greatly shortened, the problem that a large-scale system is offline is found early, the dongle is small in size and convenient to carry, in addition, the server power supply can return to the original factory without returning after being analyzed by the system provided by the application, and the service and maintenance cost is saved.
Referring to fig. 4, fig. 4 is a schematic structural diagram of another server power black box data analysis system according to the present application, where the server power black box data analysis system is based on the above embodiments:
as a preferred embodiment, the dongle 1 further comprises:
the signal phase shift circuit 15 is used for adjusting the voltage level of the element mounted on the I2C bus of the server power supply to a preset value;
the power module 14 is further configured to supply power to the signal phase shift circuit 15.
Specifically, when the signal phase shift circuit 15 has different levels for the I2C in the server power supply, the isolation and level unification functions can be realized, so as to prevent the problem of high and low level judgment caused by different levels, and finally cause the problem of data interpretation errors or mistakes.
Specifically, in the server, the voltage level of I2C is typically three types, i.e., 5V, 3.3V, and 1.8V. The voltage levels of all the devices on the I2C Bus are required to be consistent when the device is used, which would otherwise cause misjudgment of the high level or low level of the signal.
