How Does Huawei Cloud Handle a Server Fault in a DCC?

DCC provides dedicated, physically isolated computing resource pools on the cloud service platform, allowing you to use physical computing devices and resources exclusively. The physical servers automatically stop when a fault occurs. To minimize the impacts, automatic ECS migration is supported when the resources in the purchased DCC are redundant.

Servers with local disks do not support automatic migration upon system breakdown. Automatic ECS migration can be performed only when the computing resources are redundant.

After a fault occurs, the faulty physical server will be replaced with a normal one. The ID, private IP address, and EIP of the ECS remain unchanged.

Physical servers cannot be replaced when cabinets are isolated. After the fault occurs, the hardware will be repaired.
