The following explains key terms appearing in the present application.
BMC, execution server remote management controller, english name Baseboard Management controller. The method can perform firmware upgrade, check machine equipment and other operations on the machine in a state that the machine is not started. Fully implementing IPMI functionality in a BMC requires a powerful 16-bit or 32-bit microcontroller and RAM for data storage, flash memory for non-volatile data storage, and firmware to provide basic remote manageability in terms of secure remote reboot, secure re-power-up, LAN alerting, and system health monitoring. In addition to the basic IPMI and system operation monitoring functions, the mBMC can also enable BIOS flash element selection and protection by storing the previous BIOS using one of the 2 flash memories. For example, when the system fails to boot after a remote BIOS upgrade, the remote administrator may switch back to the previously-working BIOS image to boot the system. Once BIOS is upgraded, the BIOS image can be locked, so as to effectively prevent virus from invading it.
The I2C bus is a simple, bi-directional two-wire synchronous serial bus developed by Philips corporation. It requires only two wires to transfer information between devices connected to the bus. The master device is used to initiate the bus transfer of data and generate a clock to open the transfer device, where any addressed device is considered a slave device. If the host computer is to send data to the slave device, the host computer firstly addresses the slave device, then actively sends the data to the slave device, and finally the host computer terminates the data transmission; if the host is to receive data from the slave, the slave is addressed by the master first, then the host receives data sent by the slave, and finally the host terminates the receiving process. In this case, the host is responsible for generating the timing clock and terminating the data transfer.
BIOS is an acronym of English "Basic Input Output System", and the Chinese name is "basic input output System" after being translated. On IBM PC compatible systems, is a industry standard firmware interface. The computer is a set of programs solidified on a ROM chip on a main board in the computer, which stores the most important programs of basic input and output, self-checking programs after starting up and system self-starting programs, and can read and write specific information of system settings from CMOS. Its main function is to provide the lowest, most direct hardware setup and control for the computer. In addition, the BIOS provides some system parameters to the operating system. The system hardware changes are hidden by the BIOS and the program uses the BIOS functions rather than directly controlling the hardware. Modern operating systems ignore the abstraction layer provided by the BIOS and directly control the hardware components.
A CPU central processing unit (central processing unit, abbreviated as CPU) is used as an operation and control core of the computer system, and is a final execution module for information processing and program running.
Graphics processors (English: graphics processing unit, abbreviated: GPU), also known as display cores, vision processors, display chips, are microprocessors that are dedicated to performing image and graphics related operations on personal computers, workstations, gaming machines, and some mobile devices (e.g., tablet computers, smartphones, etc.).

The external cable is a PCIe bus, which is different from a hot plug supporting bus such as an SAS/SATA, an optical port and a network port, the insertion of the external cable at any time before and after the startup has no influence on the system, and the PCIe bus between the tail and the machine head must ensure reliable connection before the startup, otherwise, the corresponding equipment cannot be identified. In particular. Referring to fig. 4, the power-on self-checking method includes:
s1, after the first BMC is powered on, the register data of the first input/output expansion board are captured preferentially, wherein the register data comprise the level states of all pins of the first input/output expansion board.
After the first BMC of the first device is powered on, a detection program is firstly executed, namely, data of the level states of all pins in a register of the first input/output expansion board are read through an I2C bus.
After the heterogeneous server is electrified, a detection power supply of the external cable in the position detection device supplies power for the detection loop, and at the moment, if the external cable is in a well-inserted state, the level state of each pin of the first input/output expansion board is required to be low level.
After the machine is electrified and before the machine is started, all the indicator lamps (power indicator lamps, health indicator lamps and the like) are kept off before the correct connection of the external cables is confirmed, so that field operators are warned of abnormality, and the investigation is continued.
S2, based on the corresponding relation between each pin of the first input/output expansion board and the first port, converting the level state of each pin of the first input/output expansion board into the connection state of each external connection cable.
Establishing a one-to-one mapping relation between a first port number and the pin number of the first input/output expansion board based on the connection relation between each pin of the first input/output expansion board and the first port in advance, and binding a second port number with an association relation by the first port number; a rule for converting the level state into the connection state is preset, wherein the rule comprises that a high level state corresponds to an abnormal state and a low level state corresponds to a normal state; and converting the level state of each pin of the first input/output expansion board into the connection state of the external connection cable between the corresponding first port and the corresponding second port based on the one-to-one mapping relation and the rule.
For example, when no external high-speed cable is inserted or one end of the cable is not inserted, a pin corresponding to the tail end IO Expander is at a high level, when both ends of the high-speed cable are inserted, a pin corresponding to the tail end IO Expander is at a low level, and the BMC can acquire the connection condition of each cable by polling the IO Expander register through the I2C bus.
S3, displaying the external cable number in an abnormal connection state through the coding control digital display.
Generating a unique identity number for an external cable between a first port and a second port in advance; and writing the identity number of the external cable with the abnormal connection state into a register of the second input/output expansion board so that the second input/output expansion board controls the nixie tube to display the identity number based on a nixie tube control rule.
For example, the front window at the tail end of the machine is provided with two 8-bit nixie tubes for polling and displaying the serial numbers of the external cables which are not connected correctly, each field of the nixie tubes is controlled by an independent pin of the IO Expander, BMC codes 0-9 which needs to be displayed, and the numerical values are displayed by writing coded values into the IO Expander register through the I2C bus, so that on-site operators can acquire the cable information of abnormal connection quickly and intuitively.
The on-site information of the two ends of the external connection cable is detected, and the serial number of the cable with abnormal connection is visually displayed to the outside through the nixie tube, so that a quick and accurate checking direction is provided for on-site operators, and the dependence on the quality and the proficiency of the operators is avoided.
S4, the first BMC of the first device sends the in-place detection result to the second BMC of the second device, and the first BMC and the second BMC negotiate to start up based on the detection result.
The first BMC judges whether an external cable in an abnormal connection state exists or not: if yes, suspending executing the starting program; if not, executing the startup procedure, and sending startup prompt information to the second BMC of the second device, wherein the startup prompt information is used for informing the second BMC to execute the startup procedure.
After the tail standby power supply is electrified, firstly starting the tail BMC, and controlling all indicator lamps of the tail to be extinguished before the tail BMC detects that all cables are in place; if the external cables are not connected, the nixie tube polls and displays the serial numbers of the cables which are not inserted, so that field personnel can identify abnormality, and the corresponding cable connection is checked according to the serial numbers of the nixie tube; and after all the cables are correctly connected, the front window nixie tube is extinguished, other indicator lamps normally display, and the tail of the machine is normally started. After the power supply of the machine head is powered on, firstly the machine head BMC is started, cable in-place information detected by the machine tail BMC is obtained through the IPMB bus, if the cable is not in place, all the indicator lamps of the machine head are turned off until all the cables detected by the machine tail BMC are in place, the machine head indicator lamps are normally displayed, then the machine head is started after waiting for the standby tail to start, and after the machine tail is started, the machine head is normally started.
Whether the cable is correctly connected is used as a constraint condition for controlling the starting-up of the machine head and the machine tail, so that a large number of repair worksheets caused by nonstandard operation in the processes of putting on the shelf and moving the server are avoided, and the robustness of the system and the convenience of putting on the shelf and maintaining are improved.
