Remote upgrading method and device for IPMC program of ATCA structure

Abstract

The embodiment of the invention discloses a remote upgrading method and device for an IPMC program of an ATCA structure. The method includes the steps that a master card in an ATCA computer case obtains the IPMC upgrading program from a server; the master card executes the upgrading program and sends an upgrading control command to a slave card; the slave card receives the IPMC upgrading command sent from the master card, downloads the upgrading program from the master card through a base channel bus in a parallel mode and executes the upgrading program of the slave card. By means of the remote upgrading method and device, the transmission efficiency of IPMC files is improved greatly, all single boards are made to be independent to one another and upgraded in a parallel mode, the required time in upgrading is reduced, and upgrading efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and device for remotely upgrading an IPMC program of an ATCA framework. Background technique [0002] Advanced Telecommunications Computing Architecture (ATCA) is an open, interoperable telecommunications industry standard, mainly for telecommunications carrier applications, which consists of a series of specifications that define the mechanical structure, thermal management, power distribution and system management, supporting flexible development and configuration reuse. ATCA adopts an open and common platform architecture, which provides a cost-effective, modular, compatible, and scalable hardware architecture for communication and data network applications, and is the main direction for the development of telecommunication equipment. [0003] ATCA defines chassis standards, several rack management mechanisms, and form factors for various blade boards, and provides various b...

Problems solved by technology

[0007] The defect of the prior art 1 is that it is necessary to perform unplugging and plugging operations of the single board, and it is also necessary to insert a burner for upgrading. The operation is complicated, and the upgrading of the single board deployed on site cannot be completed without the presence of maintenance personnel.

[0010] The defect of prior art 2 is that although the upgrade does not require plugging and unplugging of the single board, it also requires the operator to connect the PC to the communication interface on the single board. , also unable to complete the upgrade

[0014] The defect of prior art three is: SHMC and the IPMC of each ATCA single board are connected by Intelligent Platform Management Bus (IPMB, Intelligent Platform, ManagementBus), and IPMB is that essence is realized by I2C bus, and I2C bus is not only slow, and at the same time Only one slave device can communicate with the master device at a time

That is, in this upgrade mode, only one IPMC slave node can communicate with the SHMC master node at the same time to realize the IPMC program upgrade. When the previous IPMC slave node is upgraded, the next IPMC slave node can be upgraded. On the whole, the IPMC program upgrade of the ATCA boards in the entire chassis is completed in a serial manner. When there are many boards in the chassis, the upgrade efficiency is not high
