Abstract
The present invention provides a fault-tolerant server based on arbitration, which relates to a server in a computer system, particularly to a fault-tolerant server. The fault-tolerant server based on arbitration overcomes the defect of mutual censure of the existing fault-tolerant server and comprises an A server 1, a B server 2, a number one arbitration unit 3, a number two arbitration unit 4, a number three arbitration unit 5, a determination unit 6 for arbitration results and a reset signal generation circuit 7, wherein the A server 1 and the B server 2 can mutually send own state information to the other party; the number one arbitration unit 3, the number two arbitration unit 4 and the number three arbitration unit 5 periodically send self-checking requests to the A server 1 and the B server 2 and receives the self-checking results of the A server 1 and the B server 2 so as to judge whether the A server 1 and the B server 2 make mistakes or not; the determination unit 6 for arbitration results is used for receiving the judgment results of the number one arbitration unit 3, the number two arbitration unit 4 and the number three arbitration unit 5 and arbitrating whether the A server 1 and the B server 2 make mistakes or not according to a principle of the obedience of minority; the reset signal generating circuit 7 is used for sending reset signals to the server making mistakes in the A server 1 and the B server 2 according to the arbitration results of the determination unit 6 for arbitration results.
Description
Technical field
The present invention relates to the server in the computer system, be specifically related to fault-tolerant server.
Background technology
At present, the server system that much has important use is out of order for software or the hardware system that prevents server, often redundant configuration has standby server, two-server is worked with mutual redundant mode or Hot Spare mode mutually, number is the disclosed fault-tolerant client-server system of patent of CN1213376Y as Granted publication.But the fault of coreference duty sometimes can appear because of the reason of soft, hardware or communication in this kind system, and promptly the A server scolds that the B server makes mistakes, and the B server scolds that the A server makes mistakes, and system can't normally be moved.
Summary of the invention
The purpose of this invention is to provide a kind of fault-tolerant server based on arbitration, it can overcome the defective of existing fault-tolerant server coreference duty.It comprises the A server and the B server that can send to the status information of self mutually the other side, and it also comprises
An arbitration unit is used for regularly sending the self check requirement and receiving the A server and the self-detection result of B server to A server and B server, thereby judges whether A server and B server make mistakes;
No. two arbitration units are used for regularly sending the self check requirement and receiving the A server and the self-detection result of B server to A server and B server, thereby judge whether A server and B server make mistakes;
No. three arbitration units are used for regularly sending the self check requirement and receiving the A server and the self-detection result of B server to A server and B server, thereby judge whether A server and B server make mistakes;
Whether the arbitration result determining unit is used to accept the result of determination of an arbitration unit, No. two arbitration units and No. three arbitration units, and make mistakes according to principle ruling A server and the B server that the minority is subordinate to the majority;
Reseting signal generating circuit is used for sending reset signal according to the server that the arbitration result of arbitration result determining unit is made mistakes to A server and B server.
Because the present invention can give the A server and whether the B server makes mistakes and which is made mistakes and provides final ruling, and by this server of makeing mistakes is resetted, has solved the problem of coreference duty between the two-server, and system can normally be moved.Reasonable in design, the reliable operation of the present invention has big promotional value.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Embodiment one: specify present embodiment below in conjunction with Fig. 1.It comprises the A server 1 and the B server 2 that can send to the status information of self mutually the other side, and it also comprises
An arbitration unit 3 is used for regularly sending the self check requirement and receiving A server 1 and the self-detection result of B server 2 to A server 1 and B server 2, thereby judges whether A server 1 and B server 2 make mistakes; The content of the self check of A server 1 and B server 2 comprises the self check of CPU, hard disk, internal memory, network interface card and power supply etc., also can design a problem bag voluntarily, by arbitration unit this problem bag is sent to server, allow server operation and operation result beamed back arbitration unit, thereby whether determining server makes mistakes.No. one arbitration unit 3 can be elected 1～5 second as to the time cycle of A server 1 and the 2 transmission self checks requirements of B server, is determined voluntarily by the user.
No. two arbitration units 4 are used for regularly sending the self check requirement and receiving A server 1 and the self-detection result of B server 2 to A server 1 and B server 2, thereby judge whether A server 1 and B server 2 make mistakes;
No. three arbitration units 5 are used for regularly sending the self check requirement and receiving A server 1 and the self-detection result of B server 2 to A server 1 and B server 2, thereby judge whether A server 1 and B server 2 make mistakes;
Whether arbitration result determining unit 6 is used to accept the result of determination of arbitration unit 3, No. two arbitration units 4 and No. three arbitration units 5, and make mistakes according to principle ruling A server 1 and the B server 2 that the minority is subordinate to the majority;
Reseting signal generating circuit 7 is used for sending reseting pulse signal according to the server that the arbitration result of arbitration result determining unit 6 is made mistakes to A server 1 and B server 2, and it is resetted.
Claims (1)
1, based on the fault-tolerant server of arbitration, it comprises the A server (1) and the B server (2) that can send to the status information of self mutually the other side, it is characterized in that it also comprises:
