Embodiment 1

[0085] An embodiment of the present invention provides an arbitration method for a hyperactive data center, see figure 2 , the arbitration method includes:

[0086] Step 101: When the first data center determines that the communication with the second data center is disconnected and the arbitration device cannot perform arbitration, the first data center checks a preset arbitration policy.

[0087] In this embodiment, the first data center and the second data center are active-active data centers.

[0088] In practical applications, whether the communication between the first data center and the second data center is disconnected can be determined according to the heartbeat packets sent between the first data center and the second data center every set time (such as 1s) . If the first data center receives the heartbeat packet sent by the second data center within the set threshold time (such as 1s, 5s), the first data center determines that the communication between the fir...

Embodiment 2

[0097] An embodiment of the present invention provides an arbitration method for a hyperactive data center. This embodiment is a further detailed introduction to the arbitration method for a user's hyperactive data center provided in Embodiment 1. See image 3 , the arbitration method includes:

[0098] Step 201: the first data center monitors in real time whether the communication between the first data center and the arbitration device, and between the second data center and the arbitration device is disconnected.

[0099] In this embodiment, the first data center and the second data center are active-active data centers, and the arbitration device is set independently from the first data center and the second data center.

[0100] In practical applications, whether the communication between the first data center and the second data center is disconnected can be determined according to the heartbeat packets sent between the first data center and the second data center every ...

Embodiment 3

[0147] An embodiment of the present invention provides an arbitration method for a hyperactive data center, which will be combined with Figure 6 Briefly introduce the application scenario of the arbitration method used in the active-active data center provided by this embodiment:

[0148] and figure 1 Compared to the application scenario shown, Figure 6 In the shown application scenario, a disaster recovery device 4 is also provided. The disaster recovery device 4 is used for backing up the data of the first data center 1 and the second data center 2, and the disaster recovery occurs in both the first data center 1 and the second data center 2. Provide service in case of failure. Such as Figure 6 As shown, the disaster recovery device 4 is connected to the first data center 1 and the second data center 2 respectively.

[0149] In practical applications, such as figure 1 As mentioned in the illustrated application scenario, the first data center 1 and the second data ce...

Abstract

Embodiments of the invention provide a method, a device, and a system for arbitration of a double-active data center, and relates to the technical field of computers. The arbitration method comprises: when communication between a first data center and a second data center is determined to be disconnected, and an arbitration device cannot arbitrate, the first data center checking a preset arbitration strategy; when according to the arbitration strategy, the first data center is determined to be a priority data center, continuing to provide service; when according to the arbitration strategy, the first data center is determined not to be the priority data center, stopping to provide service; wherein the first data center and the second data center are double-active data centers. Through the above scheme, when the communication between the first data center and the second data center is determined to be disconnected, and the arbitration device cannot arbitrate, just the priority data center continues to provide service, so that a problem of service interrupt caused by faults of the arbitration device is solved, and uninterrupted service is ensured to be provided for users.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an arbitration method, device and system for active-active data centers. Background technique [0002] For the purpose of disaster recovery (Disaster Recovery), generally at least two data centers will be built, one data center undertakes user business, and the other data center backs up data, configuration, business, etc. Active-active data centers mean that two data centers undertake business at the same time and back up each other to improve the overall service capability and system resource utilization of the two data centers. [0003] The two data centers in the active-active data center will send a heartbeat packet to each other every set time. If the heartbeat packet from the other party is not received within the set time, the backup will be interrupted. At this time, if both data centers continue to undertake business, data inconsistency will occur. The arbit...
