Embodiment Construction

[0022] As shown in FIG. 3 , it is a block diagram of the hardware structure of the intelligent platform management controller clock synchronization method of the present invention, which includes a plurality of node boards 3 respectively connected to the chassis management board 1 through the IPMB. The shelf management board 1 includes a shelf management control unit 11 that can read the clock information of the real-time clock 13 and write shelf events or node board events into the shelf log 12 . Each node board 3 includes an intelligent platform management control unit 31 and devices such as a power supply 32 and a fan 34 connected to the intelligent platform management control unit 31 , and can write the power supply 32 , fan 34 or other events into the node board log 33 . The node board 3 no longer uses the node board real-time clock for timing when recording node board events, but uses a clock signal synchronized with the real-time clock 13 of the chassis management board ...

Abstract

This invention relates to a clock synchronous method for an intelligent platform management controller including the following steps: an intelligent platform management unit of a node board registers to the frame management control unit of a frame management board after the node board is turned on, the frame management control unit sends clock setting instruction to the node board based on the real time clock of the frame, the intelligent platform management unit designs time of the node board based on the clock setting instruction, the frame management control unit sends clock synchronous instruction to the node board in definite time and the platform management unit regulates time of the node board based on the clock instruction.

Description

technical field [0001] The present invention relates to the clock technology in the field of communication, in particular to a clock synchronization method of an intelligent platform management controller in ATCA (Advanced Telecom Computing Architecture, Advanced Telecom Computing Architecture). Background technique [0002] IPMI (Intelligent Platform Management Interface, Intelligent Platform Management Interface) is an intelligent platform management interface specification jointly developed by Intel, HP, NEC, DELL, etc. It is used for the management of the ATCA (Advanced Telecom Computing Architecture, Advanced Telecom Computing Architecture) framework, including Management of power supply, monitoring of electronic key and temperature inside the frame, etc. [0003] As shown in Figure 1 and Figure 2, they are block diagrams of IPMI-based device management. The management of the ATCA framework is realized through the shelf management control unit (ShMC) 11 of the shelf ma...
