Fault tolerance processing method, apparatus, and server

A fault tolerance processing server comprising:

• a processor comprising:
• a processor core, and
• an internal controller coupled to the processor core and configured to:
• send, to an external controller and using a memory-semantic network protocol, a data read packet requesting the external controller to read data in an indicated storage location, wherein the data read packet comprises a packet format specified in the memory-semantic network protocol;
• receive, from the external controller, indication information indicating a response status of the external controller to the data read packet;
• and
• perform fault tolerance processing when the response status is an abnormal response.

A non-transitory computer-readable storage medium comprising instructions that, when executed by a processor, cause a server to:

• send, to an external controller and using a memory-semantic network protocol, a data read packet requesting the external controller to read data in an indicated storage location, wherein the data read packet comprises a packet format specified in the memory-semantic network protocol;
• receive, from the external controller, indication information indicating a response status of the external controller to the data read packet;
• and
• perform fault tolerance processing when the response status is an abnormal response.
