Method for synchronizing RTC of server

Abstract

The invention provides a method for synchronizing a RTC of a server, and belongs to the technical field of management system design. According to the method for synchronizing the RTC of the server, a home-made processor driver is designed based on a synchronous clock chip of the RTC, the RTC is synchronized with the system time, and the RTC is provided with main and standby power sources; meanwhile, the RTC can be read through out-of-band management system software when the RTC is power-on, so that time calibration is completed; moreover, the time consistency of an out-of-band management system and a server operation system can be achieved, so that the out-of-band management of a whole computer can be achieved in real time.

Description

technical field [0001] The invention relates to management system design technology, in particular to a server RTC clock synchronization method. Solving the clock consistency design problem of the platform system and the out-of-band management system under the domestic processor server platform is a method for solving the inconsistency between the clock of the out-of-band management system of the domestic processor server platform and the clock of the managed object. The clock correction of the out-of-band management system of the processor server platform keeps the time correctness of the out-of-band management system, and is an effective method for time correction of the out-of-band management system of the domestic processor server platform. Background technique [0002] In recent years, with the continuous progress of domestic processor servers, the management system design technology of domestic processor servers has become more and more critical. As a management techn...

Problems solved by technology

As a management technology that can effectively improve the operating efficiency and reliability of domestic processor servers, out-of-band management technology is being more and more widely used in actual development and design, and can independently process the data of the management system. It has also gradually been paid attention to. Although its design technology is relatively mature, there are still places to be optimized and improved under the domestic processor server platform, such as the synchronization design method for the clock of the out-of-band management system, etc.

[0003] At present, in the design of the out-of-band management system, the recording of management information and the management of management logs are mostly based on artificially setting the system time of the out-of-band management system. This method can realize the time setting of the out-of-band management system and maintain The time of the out-of-band management system is consistent with the time of the managed server, but this method is cumbersome to operate and needs to be manually recorded. Every time the system is turned on, the system time needs to be manually set, which will easily lead to operational errors and will affect the real-time performance of the management data. Brings a lot of uncertainty and reduces the effectiveness of the out-of-band management system for data processing and analysis results
