Problems solved by technology

After the SMC collects system fault information, it will generate logs and save them for user analysis. However, if there is an error in the time of each node, the user will make a wrong judgment when analyzing the fault due to inaccurate time.

Embodiment Construction

[0019] The method of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] There are compute node blades and SMC blades in the blade system.

[0021] The SMC blade is integrated with an RTC chip, such as MAXIM's DS3232SN. The RTC chip has the function of saving time and timing. The SMC and the RTC chip are interconnected through SMBUS, and the time is read from the RTC chip in a timely manner. At the same time, the SMC is interconnected with the external Ethernet, which can be compared with the network time on a regular basis, and the RTC time can be updated;

[0022] The compute node blade and the BMC are interconnected through the LPC bus for in-band and out-of-band communication. The node chipset has RTC function, such as south bridge chip, etc., that is, the system hardware clock;

[0023] The BMC and SMC are interconnected through 100M signals;

[0024] 1) First of all, the RTC time on the SMC is a reference time,...

Abstract

The invention provides a design method of clock synchronization of a blade system. By means of the design method, a complete clock synchronization process of the blade system can be achieved, the newest time of a node is enabled to be kept, log and fault information generated in the operation process of the system can be recorded into a block multiplexer channel (BMC) with accurate time, the information is finally collected to a sheet molding compound (SMC) blade for maintenance of the system by a user, and therefore fault judging efficiency and accuracy degree are improved.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a design method for clock synchronization of a blade system. Background technique [0002] The blade system has the characteristics of high density and multi-node system, and the SMC is responsible for the system management and fault handling of the whole machine. After the SMC collects system fault information, it will generate a log and save it for users to analyze. However, if there is an error in the time of each node, the user will make mistakes in judgment due to inaccurate time when analyzing the fault. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a design method for blade system clock synchronization. [0004] The purpose of the present invention is to be realized in the following manner, the blade system needs to include a system management module SMC, and an RTC chip is integrated on the SMC board, and time synchronization is p...
