The invention discloses a computer system used for maintaining data integrity. A plurality of copies are stored in a plurality of data servers which cross a plurality of data centers. The computer system comprises a network partition manager, a main controller, a router, a recovery manager and a recovery manager, wherein the network partition manager is configured to detect and manage a first network partition and a second network partition when one of a plurality of data centers fails; the main controller is configured to control the function of the data center in at least one partition in the first network partition and the second network partition; the router is configured to redirect all writing transactions in the second network partition into the first network partition; the recoverymanager is configured to connect the selected data server in the second network partition to the main controller again so as to bring convenience for the main controller to eliminate a function restriction for the selected data server; and the recovery manager is configured to recover the state and the permission information of the selected data server after the recovery manager is established tothe connection of the main controller.
Description
technical field [0001] The invention belongs to the field of data processing and management, in particular to a computer system for maintaining the data integrity of multiple copies of data fragments. Background technique [0002] Most enterprises have multiple data centers. Some businesses use passive-active data centers, where one copy of the data is placed in the active data center (i.e., the primary data center), while other data centers containing that data (i.e., the backup data center) are Passive data center. This data center implementation is generally a waste of resources, since disasters rarely leave the backup data center intact after invading the active data center. Others use active-active data centers, where both the primary and backup data centers are active. Active-active data centers are more complex, but they can serve customers very efficiently and increase server utilization for normal operations. [0003] Many businesses require active-active data c...
