Description
Technical field
The present invention relates to server technology field, specifically a kind of method for designing of blade system clock synchronous.
Background technology
Blade system has the feature of high density, multi-node system, and SMC is responsible for system management and the troubleshooting of complete machine.SMC can produce daily record and preserve for customer analysis after collecting system failure information, but if each node time exists error, then user can cause error in judgement because the time is inaccurate when analysis of failure.
Summary of the invention
The object of this invention is to provide a kind of method for designing of blade system clock synchronous.
The object of the invention is to realize in the following manner, need in blade system to comprise system management module SMC, SMC plate is integrated with RTC chip, carry out time synchronized by Ethernet and standard time; Concrete steps are as follows:
1) the RTC time first on SMC is a fiducial time, and is preserve consistent with external time, and regularly carries out time renewal by Ethernet;
2) system single node is before start, and BMC first runs, and by network from acquisition time SMC;
3) obtain up-to-date time by linking up with band in lpc bus band outward after node start, and upgrade local RTC clock;
4) enter in systematic procedure, operating system can read node R TC clock, as the operation system clock;
5) after entering system, operating system can depart from node RTC clock, namely hardware clock, can carry out relevant timework according to CPU operating frequency, if be now connected to Ethernet, also regularly can upgrade the up-to-date time by Ethernet and keep and SMC time consistency;
6) during system closedown, node system clock can be updated to node R TC clock by operating system, and node system clock is sent to BMC by lpc bus simultaneously, the SMC clock read with current BMC contrasts, if Time Inconsistency, then BMC notifies SMC by the form of interrupting, and SMC can record an event, and upgrades the up-to-date time from network;
The invention has the beneficial effects as follows: through above step, the complete Clock Synchronization Procedure of blade system can be realized, thus make the time that node keeps up-to-date, and by the daily record produced in system operation and fault message correct time to be recorded in BMC, finally be aggregated into SMC blade to safeguard system for user, increase breakdown judge efficiency and accuracy.

Embodiment
With reference to Figure of description, method of the present invention is described in detail below.
Computing node blade, SMC blade is there is in blade system.
SMC blade is integrated with RTC chip, the DS3232SN of such as MAXIM, RTC chip has the function of holding time and timing, is undertaken interconnected between SMC and RTC chip by SMBUS, and from RTC chip, reads the time in good time.Simultaneously SMC and external ethernet interconnected, can regularly and network time contrast, and upgrade the RTC time;
Computing node blade and BMC link up inside and outside band by lpc bus is interconnected.Node chip group has RTC function, such as South Bridge chip etc., namely system hardware clock;
Interconnected by 100,000,000 signals between BMC and SMC;
1) the RTC time first on SMC is a fiducial time, and is preserve consistent with external time, and regularly carries out time renewal by Ethernet;
2) system single node is before start, and BMC first runs, and by network from acquisition time SMC;
3) obtain up-to-date time by linking up with band in lpc bus band outward after node start, and upgrade local RTC clock;
4) enter in systematic procedure, operating system can read node R TC clock, as the operation system clock
5) after entering system, operating system can depart from node RTC clock, namely hardware clock, can carry out relevant timework according to CPU operating frequency, if be now connected to Ethernet, also regularly can upgrade the up-to-date time by Ethernet and keep and SMC time consistency;
6) during system closedown, node system clock can be updated to node R TC clock by operating system, and node system clock is sent to BMC by lpc bus simultaneously, and the SMC clock read with current BMC contrasts.If Time Inconsistency, then BMC notifies SMC by the form of interrupting, and SMC can record an event, and upgrades the up-to-date time from network;
Through above step, the complete Clock Synchronization Procedure of blade system can be realized, thus make the time that node keeps up-to-date, and can by the daily record produced in system operation and fault message correct time to be recorded in BMC, and be finally aggregated into SMC blade for user system is safeguarded, increase breakdown judge efficiency and accuracy.
Except the technical characteristic described in specification, be the known technology of those skilled in the art.
