High-reliability self-management daughter card and high-reliability self-management daughter card system of domestic universal server

Abstract

The invention discloses a high-reliability self-management daughter card and a high-reliability self-management daughter card system of a localized universal server, and relates to the technical field of board card management. The modules are connected according to an interaction relationship, a domestic single-chip microcomputer module is used for managing and controlling other modules in the daughter card, and a nixie tube driving module is used for driving the fault memory indicating lamp module and a digital display tube for debugging, so that the digital display tube is used for debugging each module; a serial port interconnection communication module is used for acquiring debugging information, fault memory information and board card state information of each module from a debugging serial port of a processor of the universal server, and a temperature acquisition and FRU acquisition module is used for acquiring temperature information and manufacturer information of the module where the management daughter card is located and uploading the collected health information of each module to an universal server, and a module on-off and reset module is used for realizing remote on-off and reset of each module of the management daughter card.

Description

technical field [0001] The invention discloses a management sub-card and a management sub-card system, and relates to the technical field of board card management, in particular to a high-reliability self-management sub-card and a management sub-card system of a localized general server. Background technique [0002] As the computing and control core of computer equipment, CPU is mainly responsible for instruction reading, decoding and execution. Due to the high research and development threshold and the difficulty of building an ecology, the CPU market has been led by foreign manufacturers (Intel, AMD, etc.) for many years. In recent years, with the continuous development of domestic technology and the changing situation at home and abroad, domestic processors are in a critical period of catching up. Processor manufacturers represented by Phytium, Kunpeng, Loongson, Zhaoxin, and Shenwei are booming. The upgrading of processors has been accelerated year by year, the performa...

Problems solved by technology

[0004] At present, with the development of computer technology and microelectronics technology, the role of computer systems for command, control and calculation in weapon systems is increasing day by day, and a large number of imported chips and processors have brought major security risks

However, the peripheral auxiliary debugging method of the domestic processor function machine is not perfect enough, and there is a lack of independent controllable products based on the domestic processor and the general bus interface of the key chip.
