Flexibly-configured multi-computing-node server mainboard structure and program

Abstract

The invention discloses a flexibly-configured multi-computing-node server mainboard structure and program. A processing unit is connected with PCIE equipment in parallel through I2C; the processing unit analyzes whether the acquired data of the PCIE equipment is abnormal or not; the processing unit is connected with the baseboard management controller through I2C; if the data is normal, the processing unit transmits the analyzed data to the baseboard management controller through I2C in a polling manner; if the data is abnormal, the processing unit suspends polling the transmission informationand preferentially transmits the abnormal information to the baseboard management controller, wherein the processing unit is configured with an internal clock module and an external clock module, theexternal clock module is connected with a PCH, the internal clock module and the external clock module are connected with a data selection module, and the output of the data selection module is electrically connected with the PCIE device; the PCIE equipment is connected with the PCIE switch through a PCIE bus, and the PCIE switch is electrically connected with the CPU; the CPU is electrically connected with the PCH, and the CPU is electrically connected with the storage unit.

Description

Technical field [0001] The invention relates to the field of server hardware, in particular to a flexibly configured multi-computing node server motherboard structure and program. Background technique [0002] Through BMC and CPLD to realize the management of heat dissipation, power supply and other aspects of the whole machine, BMC usually connects PCIE devices to the I2C bus to obtain information about the whole machine, including information such as temperature, device presence, and device number. [0003] Due to the limited I2C resources of BMC, I2C SWITCH is often used to expand I2C. BMC's I2C resources are limited. When too many PCIE devices are installed in the server, address conflicts are prone to occur, and when there are too many devices, the I2C polling time of BMC is too long, and real-time monitoring of device information is impossible. It is often impossible to find abnormal information in the first time, and it is impossible to conduct heat dissipation control and ...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a flexibly configured multi-computing node server motherboard structure and program, aiming to solve the problem of address conflicts when too many devices are installed in the server, and the problem that the I2C polling time of BMC is too long, and the information of the devices cannot be monitored in real time ;The PCH and CPU of the motherboard must be in place to provide clock signals for the device, resulting in the problem that the device cannot work independently, and the PCH and CPU only provide clock signals to cause resource waste.
