In addition, in order to effectively manage the chassis (enhancement) and switch of the server, the server can stably provide various services or resources, and the word processor is installed to control the chassis and switch management. Systems (eg, Roadnmner & Chassis Management System, RCMS for short) and redundant chassis and switch management systems. The backup chassis and switch management system will also replace the main chassis and switch management system in the event of an abnormality in the main chassis and switch management system to continue to manage the chassis and switches of the servos. The two chassis and switch management systems are synchronized with each other via a transmission channel provided by the Ethernet network and a special communication protocol defined by the operator. However, the two chassis are replaced by management systems, which are transmitted and updated through special communication protocols defined by the operators, so that the feeding machines manufactured by different operators cannot share the same communication protocol for the two chassis. Data transfer and update of the switch management system. ^, As can be seen from the above, in order to make the server have higher processing power, stability, reliability, security, scalability and manageability, etc., ^ add various dual backup devices to the server or Management system, but in the process of data synchronization update in the long-term dual backup I or # system, the transmission bandwidth listed above is relatively small, and the data transmission is not ': The special agreement cannot be shared. The problem, therefore, if you can open the road, 'μ back to a new server 8 200821861 service cabinet management system, the solution is happy. [Summary of the content] The problem of the river is believed to be the industry and the consumer
