Multi-computer room storage system

Abstract

The invention discloses a multi-computer room storage system. With the multi-computer room storage system adopted, the problem of difficulty in realizing consistency under the situation that data between a plurality of computer rooms are updated frequently in the prior art can be solved. The multi-computer room storage system comprises a plurality of master computer rooms and save computer rooms which store the same service data, wherein each master computer room notifies the other master computer rooms and corresponding slave computer rooms to perform synchronous update after receiving updated data, and the master computer rooms can perform two-way data transmission between each other in the synchronous update process; the multi-computer room storage system further comprises a comparison server which is used for comparing data in the master computer rooms periodically, and determining master rooms which have correct data when finding that data are inconsistent, and updating data in the other computer master rooms according to data stored in the master computer rooms which have the correct data.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a multi-room storage system. Background technique [0002] With the increasing popularity of network services, the number of user visits is increasing. If all business data is stored on a server, the server will often fail due to excessive visits. Moreover, it is limited by the storage space of the server. , in an application scenario with a large amount of business data, one server often cannot carry all the business data. Therefore, multiple servers are required to jointly provide services for users. For this reason, multiple servers that are jointly used to provide a certain service can be set in the same computer room, and the computer room provides the service to users. [0003] In addition, in practical applications, it is often necessary to store some commonly used business data in multiple computer rooms at the same time. For example, in order to provide the same s...

Problems solved by technology

[0004] In the above situation, the data in multiple computer rooms needs to be consistent. Once the data in each computer room is inconsistent, it will affect the normal use of users.

Due to frequent changes in business data, once the data in a certain computer room is changed, other computer rooms do not update synchronously in time, resulting in data inconsistency

Moreover, if multiple computer rooms are updated at the same time, it is more likely to cause data inconsistency

Therefore, there is currently no effective mechanism to ensure that the data in multiple computer rooms is completely consistent
