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

[0015] The method of the present invention is described in detail below with reference to the accompanying drawings.

[0016] There are computing node blades and SMC blades in the blade system.

[0017] An RTC chip is integrated on the SMC blade, 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 due course. At the same time, the SMC is connected to the external Ethernet, which can be compared with the network time regularly, and the RTC time can be updated;

[0018] Computing node blades and BMC are interconnected through the LPC bus for in-band and out-of-band communication. The node chipset has the RTC function, such as the south bridge chip, which is the system hardware clock;

[0019] BMC and SMC are interconnected through 100M signal;

[0020] 1) First of all, the RTC time on the SMC is a reference time, and it is consistent with the e...

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 a high-density, 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 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 due to inaccurate time when analyzing the fault. Contents 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, needs to comprise system management module SMC in the blade system, is integrated with RTC chip on the SMC board, carries out time synchronization by...
