A data management method comprises a first processing node that obtains a secure storage key based on a first external keying material corresponding to the first processing node, encrypts data corresponding to an application program in the first processing node, and sends encrypted data to a second processing node. The second processing node obtains a secure storage key based on a second external keying material corresponding to the second processing node, and decrypts the encrypted data that corresponds to the application program and that is sent by the first processing node. The second external keying material is the same as the first external keying material, whereby the second processing node and the first processing node may obtain a same secure storage key, and the second processing node may successfully decrypt the encrypted data that corresponds to the application program and that is sent by the first processing node.

Data management method, apparatus, and system, and storage medium

This application discloses a mirrored memory configuration method and apparatus, and a computer storage medium, and belongs to the field of information processing technologies. The method includes the following: After a computer apparatus is started, if the computer apparatus is currently in an OS state and obtains a mirrored memory establishment request, the computer apparatus may switch from the OS state to a BIOS state through system interruption. Then the computer apparatus configures a mirroring relationship in the BIOS state, and switches to the OS state again after configuring the mirroring relationship, to reconfigure a mirrored memory.

Mirrored memory configuration method and apparatus, and computer storage medium

A memory data migration method, apparatus, and system are provided. During memory migration, data is classified into two parts based on a hot and cold degree of the data. Hot data is directly migrated, and cold data is written into a shared storage device shared by memories. When needing to be used in a destination-end memory, the cold data may be read from the shared storage device. This reduces an amount of data that needs to be migrated to the destination-end memory, thereby improving memory migration efficiency.
