A sensor scanning method and a substrate management controller

Abstract

The embodiment of the present invention discloses a sensor scanning method and a baseboard management controller. The method includes that the baseboard management controller obtains the topology information of the baseboard management controller from the topology storage module of the baseboard management controller and detects whether an adapter card is inserted. to the slot of the baseboard management controller, the adapter card stores the topology information of the adapter card, if the detection result is yes, the baseboard management controller obtains the identification information of the adapter card inserted into the slot, and then according to the baseboard management control Generate global topology information for describing the global topology structure by using the topology information of the device, the topology information of the adapter card, and the identification information of the slot where the adapter card is inserted, and scan the sensors in the adapter card according to the global topology information. Implementation of the embodiments of the present invention enables the baseboard management controller to quickly acquire global topology information for scanning sensors in the adapter card, reduces coupling of software and hardware and code expansion, and avoids frequent upgrades of the baseboard management controller.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a sensor scanning method and a substrate management controller. Background technique [0002] The IIC (Inter-Integrated Circuit, integrated circuit) bus is a bus that uses the fewest signal lines among various buses and has functions such as automatic addressing, multi-master clock synchronization and arbitration. Small and other advantages, IIC bus has been widely used. In BMC (Baseboard Management Control, Baseboard Management Controller), most of the sensors that BMC needs to monitor are IIC devices, and these sensors are included in one or more adapter cards. The more sensors that BMC needs to monitor, the topology of IIC The more complicated it is, in addition, the types of adapter cards that BMC needs to support are also increasing. The existing technology can scan the sensors in the adapter card by adding the relevant information of the adapter card (such as th...
