Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The detection device based on the CPLD can be applied to a multi-path server shown in fig. 1, wherein a main CPLD module acquires state lamp parameters of each module in a main server node; the method comprises the following steps that at least one slave CPLD module obtains state light parameters of each module in slave server nodes, wherein each slave server node comprises at least one slave CPLD module; the master CPLD module receives the state lamp parameters acquired by the at least one slave CPLD module; and the main CPLD module determines the working states of all the modules of the multi-path server according to all the state lamp parameters and the state parameter table set by the user. The problem that the working state of the modules in the lower-layer node in the multi-path server is not easy to check is solved by receiving and displaying the protocol frames through the serial port screen, and the working state of each module is conveniently and accurately known by maintenance personnel, so that the working pressure of the maintenance personnel is reduced.

In one embodiment, the multi-path server forms a plurality of server nodes, each server node includes at least one path server, and the detecting device includes:

and the main CPLD module calculates the state light parameters of each module in the main server node according to the flickering times of the state lights.

Specifically, taking an eight-way server as an example, there are four server nodes in the eight-way server, each server node has two CPUs (central processing units), the top layer is a main server node 0, the bottom layers are server nodes 1,2, and 3 in sequence, the four computing nodes are interconnected through a middle back panel from top to bottom, and each node has a BMC (baseboard management Controller), a PCH (PLATFORM for Controller HUB PLATFORM control center), commonly called south bridge chip, and a CPLD (Complex Programmable Logic Device). The main CPLD accesses the BMC module and the PCH module in the main server node, records the flashing times of the respective status lamps according to the time set by the user in advance, wherein the name of the status lamp of the PCH is POSTCODE LED, for example, if the flashing times of the BMC status lamp is recorded within one minute to be 120 times, the flashing rate of the BMC in the main computing node can be calculated to be 2 times/second.

In one embodiment, the at least one slave CPLD module obtaining the status light parameter of each module in the slave server node includes:

Specifically, the slave CPLD in the master computing node 1-3 accesses the BMC module and the PCH module in the slave server node, and records the number of times of flashing of each status light according to the time set in advance by the user, for example, if the number of times of flashing of the post mode LED of the PCH status light is recorded within one minute is 150, the rate of flashing of the BMC in the master computing node can be calculated to be 2.5 times/second.

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

Specifically, a user can set a state parameter table in advance, the state parameter table comprises a mapping relation between the flashing times and the working states of the state lamps, for example, the flashing rate of the BMC in the state parameter table can be set to be that the flashing times per minute are 1-10 times, the flashing times per minute are normal, the flashing times per minute are 30-30 times, the flashing times per minute are busy, when the flashing is not performed, it is determined that the chip has a fault, and when the master CPLD in the computing node 0 obtains that the flashing rate of the BMC in the node is 15 times, it can be determined that the BMC is idle. The mapping relation between the flashing rate and the working state of different modules on the same node, such as the BMC and the CPLD, can be different, and a user can set the flashing rate and the working state according to the actual working requirement. The module flashing rate range values on each computing node can be different, for example, the BMC flashing rate on the computing node 1 can be set to be idle when the flashing times per minute are 1-5 times, normal when the flashing times per minute are 5-50 times, busy when the flashing times per minute are 50-100 times, when the flashing is not performed, the chip is determined to be in failure, and the user can set the flashing rate range values by himself according to the actual working requirements.

In one embodiment, the method further comprises:

Specifically, the generated protocol frame may be as shown in fig. 2, where the protocol frame includes a frame header, a BMC operating state in all nodes, a PCH operating state, a CPLD operating state, and a frame tail. 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 lamp corresponding to the BMC can be displayed to be blue.

The modules in the multi-server state detection device based on the CPLD can be wholly or partially realized by software, hardware and a combination thereof. The modules can be embedded in a hardware form or independent from a processor in the computer device, and can also be stored in a memory in the computer device in a software form, so that the processor can call and execute operations corresponding to the modules.

In one embodiment, as shown in fig. 3, the present invention provides a CPLD-based detection method, where the multiple servers form multiple server nodes, each server node includes at least one server, and the method includes:

s301, the main CPLD module acquires state light parameters of each module in the main server node;

s302, at least one slave CPLD module acquires the state lamp parameters of each module in the slave server nodes, wherein each slave server node comprises at least one slave CPLD module;

s303, the main CPLD module receives the state lamp parameters acquired by the at least one slave CPLD module;

and S304, the main CPLD module determines the working states of all the modules of the multi-path server according to all the state lamp parameters and the state parameter table set by the user.

In one embodiment, the method further comprises:
