The main CPLD module is further configured to receive the at least one status light parameter obtained from the CPLD module, and determine the working status of all modules of the multi-channel server according to all the status light parameters and the status parameter table set by the user.

In one embodiment, the acquisition of the status light parameters of each module in the main server node by the main CPLD module includes:

The main CPLD module records the flashing times of the status lights of each module in the main server node within the unit time set by the user;

The main CPLD module calculates the status light parameters of each module in the main server node according to the flashing times of the status light.

Specifically, taking an eight-socket server as an example, there are four server nodes in the eight-socket server, and each server node has two CPUs (central processing unit central processing units). The top layer is the main server node 0, and the following are the servers Nodes 1, 2, and 3, four computing nodes are interconnected from top to bottom through the mid-backplane. Each node has a BMC (Baseboard Management Controller) and a PCH (PLATFORM CONTROLLERHUB Platform Control Center) commonly known as the South Bridge Chip, a CPLD (Complex Programmable Logic Device complex programmable logic device). The main CPLD accesses the BMC module and the PCH module in the main server node, and records the flashing times of the respective status lights according to the time set by the user in advance. The name of the PCH status light is POSTCODE LED. If the number of blinks is 120, it can be calculated that the blink rate of the BMC in the main computing node is 2 times/second.

Specifically, the slave CPLDs in the master computing nodes 1-3 access the BMC module and the PCH module in the slave server nodes, and record the flashing times of the respective status lights according to the time set by the user in advance, for example, record the PCH status within one minute. If the number of flashes of the light POSTCODE LED is 150 times, it can be calculated that the flashing rate of the BMC in the main computing node is 2.5 times/second.

In one embodiment, the main CPLD module receiving the at least one status light parameter obtained from the CPLD module includes:

Specifically, the CPLD of computing node 0 is used as the master device, and the CPLDs of computing nodes 1, 2, and 3 are used as slave devices, which are interconnected on the mid-backplane to establish a dedicated I2C (Inter-Integrated Circuit two-wire serial bus) communication link.

In one embodiment, the state parameter table includes a first parameter range and a second parameter range, and the working state includes idle, normal, busy, and fault.

Specifically, the user can set the status parameter table in advance. The status parameter table includes the mapping relationship between the number of flashes of the status light and the working status. For example, the BMC flashing rate in the status parameter table can be set to 1-10 flashes per minute. Idle, the number of blinks per minute is 10-30 times, it is working normally, and the number of blinks per minute is 30-60 times is busy, and when it does not blink, it is determined that the chip is faulty, when the main CPLD in the computing node 0 obtains the When the blinking rate of the BMC in this node is 15 times, it can be determined that the BMC is idle. Different modules on the same node, such as BMC and CPLD, have different mapping relationships between the blinking rate and the working state. Users can set it according to the actual needs of the work. The module blinking rate range value on each computing node can also be different. For example, the BMC blinking rate on compute node 1 can be set to 1-5 blinks per minute as idle, and 5-50 blinks per minute as working Normally, the number of flashes per minute is 50-100 times, which means that the work is busy, and when it does not flash, it is determined that the chip is faulty. According to the actual needs of the work, the user can set it by himself.

In addition, the serial port screen can display different colors according to different working states. For example, when the BMC is determined to be idle, the corresponding light of the BMC can be displayed as blue.
