Abstract: A fault tolerance processing method includes: sending, by a server, a data read packet to an external controller, where the data read packet is used to request the external controller to read data in an indicated storage location, and a packet format of the data read packet complies with a packet format specified in the memory-semantic network protocol; receiving, by the server, indication information sent by the external controller, where the indication information is used to indicate a response status of the external controller to the data read packet; and determining, by the server, the response status of the external controller to the data read packet based on the indication information, and performing fault tolerance processing when the response status is an abnormal response.

Abstract: A first cluster and a second cluster include at least one single-threaded main controller, the at least one single-threaded main controller processes one access request requesting for data at a time, and the data accessed by the access request is jointly managed by the first cluster and the second cluster. A database server determines hot data managed by the first cluster and determines whether a migration condition for migrating the hot data to the second cluster is met. The second cluster manages hot data that meets the migration condition. The database server migrates the hot data that meets the migration condition to the second cluster and triggers an update of an access path of the hot data.
