Description

Technical Field

[0001] The utility model belongs to the technical field of servers, and in particular relates to a server with multiple access channels. Background Art

[0002] In recent years, Internet technologies such as big data, artificial intelligence, the Internet of Everything, and cloud services have developed rapidly, and the requirements for the storage capacity and processing speed of massive data are getting higher and higher. As the cornerstone of the Internet of Things, servers are responsible for data storage, data processing, and data interaction. The rapid development of the Internet has posed higher challenges to the development of servers. For storage servers, the data stored is generally confidential data, and the server can only be accessed by accessing the local area network. This means that if you want to obtain basic information such as the server's status and configuration, you need to use a computer to access the local area network or use a network cable to connect the server and the computer to form a separate local area network.

[0003] For example, both the computer and the server are connected to the LAN through the network cable interface. The computer accesses the server through the server's IP address. The computer is connected to the network card module on the server through Ethernet. The network card and the BMC communicate through the NCSI shared port and the RGMII shared port. The BMC in the server develops and designs a web graphical interface, reads the server's status and basic configuration, and writes it to the web interface for visualization. The computer reads the basic information and status of the server through the web interface, and can perform simple control (such as power on and power off) of the server peripherals (such as the backplane, fan board, and power on / off buttons). If you are in the computer room, you need to connect to the server through a direct network cable to achieve access.

[0004] The two currently used methods of accessing and controlling the server both require a computer and a network cable connection. The portability of the computer terminal is poor, and the method of building a local area network based on Ethernet cables requires that the terminal and the remote end are in the same IP domain. The IP address of the computer or server needs to be modified each time before the connection access operation can be performed, which is very cumbersome. Utility Model Content

[0025] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] The key terms appearing in the present invention are explained below.

[0028] BMC, the server remote management controller, is called Baseboard Management Controller in English. It can perform some operations such as firmware upgrade and machine equipment viewing on the machine when the machine is not turned on. Fully implementing IPMI functions in BMC requires a powerful 16-bit or 32-bit microcontroller, RAM for data storage, flash memory for non-volatile data storage, and firmware, which can provide basic remote manageability in terms of safe remote restart, safe power-on, LAN warning, and system health monitoring. In addition to basic IPMI functions and system operation monitoring functions, mBMC can also realize the selection and protection of BIOS fast components by using one of the two flash memories to store the previous BIOS. For example, when the system cannot be started after a remote BIOS upgrade, the remote administrator can switch back to the previously working BIOS image to start the system. Once the BIOS is upgraded, the BIOS image can also be locked to effectively prevent viruses from invading it.

[0029] The I2C bus is a simple, bidirectional, two-wire synchronous serial bus developed by Philips. It only needs two wires to transmit information between devices connected to the bus. The master device is used to start the bus to transmit data and generate a clock to open the transmitting device. At this time, any addressed device is considered a slave device. The relationship between the master and the slave, the send and receive on the bus is not constant, but depends on the data transmission direction at this time. If the host wants to send data to the slave device, the host first addresses the slave device, then actively sends data to the slave device, and finally the host terminates the data transmission; if the host wants to receive data from the slave device, the master device first addresses the slave device. Then the host receives the data sent by the slave device, and finally the host terminates the receiving process. In this case, the host is responsible for generating the timing clock and terminating the data transmission.

[0030] The central processing unit (CPU) is the computing and control core of the computer system and is the final execution module for information processing and program running.

[0031] To facilitate understanding of the present invention, the server with multiple access channels provided by the present invention is further described below based on the principle of the server with multiple access channels of the present invention, in combination with embodiments and drawings.

[0032] For details, please refer to Figure 1 , servers with multiple access channels include:

[0033] BMC, BMC is communicated with the CPU, BMC is communicated with the mainboard controller; BMC is communicated with the sensor; BMC is communicated with the network card; BMC is communicated with the Bluetooth chip on the mainboard; the network card is electrically connected to the first power supply module, the Bluetooth chip is electrically connected to the second power supply module, the first power supply module and the second power supply module are both arranged on the mainboard, and the mainboard controller controls the power supply status of the first power supply module and the second power supply module.

[0034] Specifically, the server motherboard has CPU, BMC, Bluetooth chip, motherboard controller (CPLD is used in this embodiment), network card and other chips, and many peripheral boards are mounted on the motherboard, such as fan board, backplane, power board, etc. BMC is connected to the motherboard controller through line bmc_i2c2, BMC is connected to the sensor through line bmc_i2c2, BMC is connected to the CPU through line bmc_i2c2, and BMC is connected to the Bluetooth chip through line bmc_i2c1. BMC is connected to other boards through line bmc_i2c0. BMC is connected to the network card through network cables NCSI and RGMII.

[0035] The main control chips of the fan board, backplane, power board and the CPU, CPLD and other chips on the mainboard will send the basic information, configuration information, status information, etc. of the peripheral boards and the mainboard to the BMC. At the same time, the BMC is connected to the Bluetooth chip and exchanges data through the I2C protocol. Since the current Bluetooth chip has low power consumption, it will not affect the heat dissipation of the server.

[0036] Among them, the Bluetooth chip can establish a communication connection with a handheld terminal with Bluetooth communication function. The BMC is connected to the Bluetooth chip through I2C; the handheld mobile terminal reads the server information from the server through Bluetooth; the handheld mobile terminal can also send commands such as power on and off, and the Bluetooth on the server receives the command and sends it to the BMC, which controls the server's power on, power off, restart and other operations.

[0037] In order to facilitate the selection of channel activation, a controllable power supply structure is designed for the Bluetooth chip. Specifically, a key switch circuit is added, and the signal output end of the key switch circuit is connected to the mainboard controller. The mainboard controller switches the power-on and power-off states of the second power supply module based on the signal of the signal output end. The key of the key switch circuit is installed on the server chassis. That is, after pressing the key, the mainboard controller receives the electrical signal and controls the second power supply module to power on the Bluetooth chip. After pressing the key again, the mainboard controller receives the electrical signal again and controls the second power supply module to power off the Bluetooth chip.

[0038] like Figure 2 As shown, the key switch circuit includes: a power input end, the power input end is connected to the emitter of the first transistor Q1, the collector of the first transistor Q1 is connected to the signal output end, and the signal output end is further connected to the CPLD, that is, the mainboard controller; the power input end is connected to one end of the first resistor R1, the other end of the first resistor R1 is connected to one end of the key S1, and the other end of the key S1 is connected to the base of the second transistor Q2; the other end of the first resistor R1 is grounded through the second resistor R2; the other end of the first resistor R1 is connected to one end of the first capacitor C1; the key The other end of key S1 is connected to the other end of first capacitor C1 via third resistor R3; the other end of key S1 is connected to the other end of first capacitor C1 via second capacitor C2; the collector of second transistor Q2 is connected to the base of first transistor Q1, and the emitter of second transistor Q2 is connected to the other end of first capacitor C1; the other end of first capacitor C1 is grounded via fourth resistor R4; the collector of first transistor Q1 is connected to the base of second transistor Q2 via fifth resistor R5; sixth resistor R6 is connected in parallel between the emitter and base of first transistor Q1. 3.3V power supply is used at power input end. Among them, first transistor Q1 is PNP transistor, and second transistor Q2 is NPN transistor.

[0039] When the button S1 is not pressed, it is in the disconnected state. At this time, R1 and R2 form a voltage divider circuit, C1 is charged, and the charging circuit is 3.3V-R1-C1-R4. Q1 and Q2 are not turned on, and there is no electrical signal output at the signal output end. After the button S1 is pressed, it is in the on state, C1 is discharged, and the discharge circuit is C1-S1-R3 / C2 / Q2-C1. R3, C2, and Q2 are connected in parallel. After C1 is discharged, a positive voltage signal is formed on R3, which turns on Q2. After Q2 is turned on, the collector of Q2 sends an electrical signal to the base of Q1 to turn on Q1. C2 is to improve the conduction stability of Q2. The collector voltage of Q1 returns an electrical signal to the base of Q2 through R5, making it in a stable on state, and the signal output end outputs an electrical signal stably.

[0040] In order to know the status of the Bluetooth chip from the outside, the server also includes an indicator light for displaying the power-on and power-off status of the second power supply module, and the indicator light is installed on the server chassis. The power-on indicator light is green, and the power-off indicator light is off.

[0041] Please refer to Figure 3 In one application scenario, after a handheld mobile terminal accesses the server, the display interface includes system information, system log, power control, fan management, sensor information, historical curves, etc. The system information tab can display specific information of the device, such as the CPU, manufacturer, main frequency, etc.; memory type, capacity, etc.; hard disk backplane, CPLD version number, temperature, etc.; the power tab will display PSU information, output power, health status, etc. The log & diagnostic tab will display the log of each abnormal time or system operation event recorded by the BMC. Users can perform debug operations by querying the system log; the fan management tab can obtain the fan board CPLD version, fan number, fan speed information, and can control the fan speed; power control can control the server power on, power off and restart operations; the historical curve tab shows the current server power consumption in real time; sensor information can display the temperature information sent back by each temperature sensor, and record the real-time temperature of different temperature measurement points of the server. The return button on the left can return to the previous layer, and the exit button can exit the server connection and enter the Bluetooth connection page to re-establish the Bluetooth connection. The company logo is placed in the upper left corner. The APP uses a graphical interface to enable real-time access and control of the server status on a handheld mobile terminal.

[0042] Although the present invention is described in detail by referring to the accompanying drawings and in combination with the preferred embodiments, the present invention is not limited thereto. Without departing from the spirit and essence of the present invention, a person skilled in the art may make various equivalent modifications or substitutions to the embodiments of the present invention, and these modifications or substitutions shall be within the scope of the present invention.
