Embodiment Construction

[0015] refer to figure 1 Shown is an application environment diagram of a preferred embodiment of the BMC-based motherboard management system of the present invention.

[0016] The motherboard management system 10 based on the baseboard management controller runs in the BMC chips B1, B2, B3, and B4 respectively. The BMC chip is an independent board installed on the main board of the server, including firmware, memory, general purpose input and output interface (General Purpose Input Ouput Pin, GPIO pin), etc., used to connect with the processor and various components on the main board, Detect the state of each physical component.

[0017] The BMC chip can realize real-time monitoring of the server motherboard, monitor the CPU (Central Processing Unit), memory, hard disk, fan, etc. on the motherboard, and obtain CPU utilization, memory occupancy, hard disk I / O access (Input / Output ), fan speed and other information, when the above-mentioned monitored quantity exceeds a certai...

Abstract

The invention provides a mainboard management method based on a baseboard management controller, and is applied to a BMC (Baseboard Management Controller) chip accessed into a server backboard. The method comprises the following steps: according to the level state value of a GPIO (General Purpose Input / Output) pin of the BMC chip, judging whether the current BMC chip is a main BMC chip or not; according to an address selection signal of a control end of a data selector on the backboard, setting an index value of each connector on the backboard, wherein each connector is connected with one EEPROM (Electrical Erasable Programmable Read Only Memory) in one-to-one correspondence, an input end of the data selector is connected with each EEPROM on the backboard, and an output end and the control end of the multiplexer are connected with the main BMC chip through a connector; generating a list head node of a linked list of the mainboard, marking the state of the linked list, and storing the linked list into the EEPROM corresponding to the connector accessed into the mainboard; backuping a mainboard exception event to the linked list of the mainboard.

Description

technical field [0001] The invention relates to main board management of a server, in particular to a main board management system and method based on a base board management controller. Background technique [0002] At present, when managing servers in most data centers or server rooms, rack-type cabinets are used to connect multiple servers through connectors on the backplane to achieve unified management. Generally speaking, a baseboard management controller (BMC chip for short) is configured on the motherboard of the server to monitor the physical values ​​of each hardware on the motherboard (CPU temperature, fan speed, etc.) state. [0003] Administrators can access the system event log (System Event Log, system event log) in the BMC chip of each motherboard to grasp the running status of each server motherboard. However, when a motherboard's BMC chip crashes, administrators cannot access the system event log. When too many servers are connected to the backplane, adm...
