Description
Technical Field
The present disclosure relates to the field of computer technologies, and in particular, to a method, an apparatus, an electronic device, and a storage medium for communication between a node and a user interface board.
Background
Taking the whole storage controller with four nodes as an example, at present, BMCs (Baseboard Management Controller, baseboard management controllers) inside the four nodes are interconnected with CPLDs (Complex Programmable Logic Device, complex programmable logic devices) and sendors on a UI (User Interface) board through I2C (Inter-Integrated Circuit, two-wire serial bus). The current software mechanism can ensure that at most, the BMC of one node can control the indicator lamp and the display module on the UI board through the CPLD of the UI board, and the problem of data conflict caused by the fact that the BMC of the plurality of nodes simultaneously performs I2C communication with the CPLD on the UI board is avoided. However, because the BMC of each node needs to acquire the temperature information on the UI board, the BMC of a plurality of nodes performs I2C communication with the SENSOR on the UI board at the same time, and because the arbitration mechanism of the I2C communication is not provided in the BMC, when the plurality of nodes (more than or equal to two nodes) access the SENSOR of the UI board at the same time, because a plurality of main devices are provided on the I2C bus, the data conflict is caused by the multi-main communication, and thus the BMC fails to acquire the temperature information.
In addition, the communication between the internal node of the storage controller and the UI board involves 5 signal wires, and the number of the signal wires is large, and as the hardware link of each signal wire involves a plurality of single boards, a plurality of connectors and cables, the complexity of the design of hardware, structure and cables is increased, and the cost is increased.
Meanwhile, the UI plate is positioned in the hanging lugs of the whole machine, and the space in the hanging lugs is narrow, so that the size of the UI plate and the layout of components on the UI plate are greatly limited. Because the communication between the internal node of the memory controller and the UI board involves 5 signal wires, and the transmission of the power supply and GND signals is considered, the connector on the UI board is difficult to select. The current common solution is to directly weld the cable on the UI board, and no wire-to-board connector on the UI board is used any more, but this may cause inconvenience in replacement or maintenance of the UI board due to the fact that the UI board is welded with the cable as a whole.
Therefore, how to optimize the communication method between the node and the user interface board, and simplify the link complexity is a problem to be solved.

Specifically, as the current software mechanism can ensure that the node indicator control data and the node display module control data of at most one node in the plurality of nodes are valid, after the UI plate detects that the node indicator control data and the node display module control data of a certain node are valid, the state of the positioning indicator, the state of the alarm indicator and the display state of the display module can be set according to the value of the register; meanwhile, if the UI board detects that the node indicator control data and the node display module control data of all the nodes are invalid, the UI board maintains the previous setting of the indicator state and the display state of the display module.

Referring to fig. 3, the indication lamps on the ui board include a power indication lamp, a positioning indication lamp, and an alarm indication lamp of the whole server. Wherein, the power indicator lamp generally uses green lamp. Particularly, when the CPU system in any controller node is electrified, the power indicator lamp is normally on; similarly, the green light may be in a 0.5Hz blinking state when the CPU systems in all controller nodes are not powered up.
In some embodiments, the node indicator control data includes at least one of positioning indicator control data and alarm indicator control data; the node indicator control registers include at least one of a positioning indicator control register and an alarm indicator control register.
Specifically, the positioning lamp generally uses a blue lamp, the blue lamp is always on to indicate that the positioning signal is effective, and the blue lamp is off to indicate that the positioning signal is ineffective; the warning lamp is generally a red lamp, the red lamp is normally on to indicate that the warning signal is effective, and the red lamp is off to indicate that the warning signal is ineffective.

and the second serial data line of the storage controller node is combined on the backboard and then is subjected to pull-up processing, and the pulled-up data signals are connected to the user interface board.
Specifically, the BMC inside the node and the CPLD inside the node are interconnected through a first I2C bus, where the I2C serial bus has two signal lines, one is a bidirectional data line SDA, and the other is a clock line SCL. Among these two lines, SCL is a clock line for synchronizing clock signals; the SDA is a data line for transmitting data. All serial data SDA connected to the I2C bus devices are connected to the SDA of the bus, and the clock line SCL of each device is connected to the SCL of the bus, belonging to a master multi-slave bus. The master can only communicate with one slave at a time, and if data is to be transmitted with multiple slaves, a polling mode is required. The CPLD and the connector inside the node are interconnected through a second I2C bus, and the second I2C bus is connected to the UI board through the backboard and is interconnected with the CPLD and the sensor on the UI board. The second two-wire serial bus IIC_SCL of the four nodes is combined on the backboard and then is subjected to pull-up processing, and a signal after pull-up is connected to the UI board; and similarly, IIC_SDA of the four nodes is combined on the backboard and then is subjected to pull-up processing, and the signals after pull-up are connected to the UI board.
