Operation protection method for server backplane

Abstract

The invention provides an operation protection method for a server backplane, which establishes an adaptive setting mechanism for the overcurrent protection point of the server backplane, establishes a backplane operation overcurrent protection unit on the server mainboard, and is responsible for collecting and obtaining the load information of the current backplane, And according to the load information, adjust the overcurrent protection point of the power supply path from the motherboard to the backplane; establish an automatic current limiting mechanism after the backplane overcurrent, and establish a server backplane abnormal control unit, which is placed on the server backplane , by controlling the on and off of the power MOS placed at the power supply input end of each hard disk, the independent power supply control for each hard disk is realized. When the local temperature changes too fast, it will actively cut off the power supply of the corresponding path, realize the isolation of the abnormal area, realize the abnormal process control of the backplane, and ensure the reliability of the system.

Description

technical field [0001] The invention relates to the field of servers, in particular to an operation protection method for a server backplane. Background technique [0002] The server backplane is connected to all hard disks in the system, and its reliable operation plays a key role in the stability of data services. After the server backplane leaves the factory, it needs to work stably for a long time in various complex environments, such as high temperature, high humidity, In various possible harsh environments such as high noise, this puts forward stricter requirements for the operation protection of the server backplane. During the operation of the server backplane, it is necessary to have reliable protection measures, and at the same time be able to identify and deal with it in time. exceptions, to ensure the stable operation of the server system. [0003] In the current server system backplane operation, when the server backplane fails, such as power supply current ove...

AI Technical Summary

Problems solved by technology

[0003] In the current server system backplane operation, when the server backplane fails, such as power supply current overcurrent, local area overheating, effective adaptive protection cannot be achieved, and there are cases such as board burning and data loss. For the system The overall stability of the system has a greater impact. At present, fuses are only added to the power supply input end of the backplane for protection. The current system backplane operation protection method has relatively large disadvantages. The protection method of a fixed fuse can only protect a specific short circuit. When the abnormal current is lower than the short-circuit current, the protection cannot be effectively identified. At the same time, due to the wide variety of hard disks, the number of actual hard disks installed also varies greatly, and the total current protection requirements also vary greatly. Therefore, the current backplane fuse The protection is too single, and the protection point cannot be automatically adjusted according to the change of the load. There is a risk of burning the board, and the security of the flexible configuration of the system cannot be guaranteed.

Due to the complex working environment of the server backplane, the PCB may gradually fail as the environment changes, which will lead to a sharp rise in the temperature of the local PCB on the backplane. The overall system is abnormal, or even cause the system to go down, and the reliability of the system cannot be guaranteed
