Server, node equipment information acquisition method and device thereof, equipment and medium

Abstract

The invention discloses a server and a node equipment information acquisition method and device thereof, electronic equipment and a readable storage medium. A management board where the BMC of the multi-node server is located is in butt joint with a board where the master node is located, and management signals are transmitted to the slave nodes through the master node and the middle backboard. The BMC is connected with the logic unit of each node, the logic unit of the master node is connected with the logic units of the slave nodes, and the logic units of the nodes are connected with the corresponding node devices. The method comprises the following steps: receiving an equipment information acquisition instruction, and determining a target node and target equipment for reading equipment information by analyzing the equipment information acquisition instruction; if the target equipment is the logic unit, reading required data from the logic unit of the target node; and if the target device is not the logic unit, sending the device information acquisition instruction to the main node, and acquiring the data of the target device of the target node through the main node, thereby effectively improving the efficiency of accessing the node device of the multi-node server by the BMC.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a method, device, electronic device, and readable storage medium for acquiring information of a server and its node equipment. Background technique [0002] With the development of information technology, servers are not only widely used in daily life and work, such as in finance, medical care, energy and other industries, but also require large-scale core databases, virtualization integration, memory computing, and high-performance computing. Higher and higher, multi-channel multi-node server applications are born. [0003] The BMC (Baseboard Management Controller, baseboard management controller) chip is the management core of the server, which is responsible for managing the information of various devices in the whole system, such as each PCIE (peripheral component interconnect express, high-speed serial computer expansion bus standard) device information, Tem...

AI Technical Summary

Problems solved by technology

And because BMC accesses all devices in the system through polling, if there are too many devices connected to nodes in each group of buses, the time for BMC to access the devices of the nodes will increase, which will not only cause long polling time, low access efficiency, but also At the same time, when the system is abnormal, all useful information in the system cannot be collected effectively, which is not conducive to the stable and reliable operation of the system

In addition, in order to meet the daisy chain topology of the I2C link, the trace link on the server board is very long, such as figure 1 As shown, the management topology of the whole machine system is complex and high, which is not conducive to maintenance
