摘要： A central processing unit (CPU) hot-remove method, including determining, by a controller of a server that has a non-full mesh first CPU topology comprising multiple CPUs, a first CPU of the multiple CPUs to be removed from the first CPU topology according to first indication information, determining at least one second CPU associated in the first CPU topology with the first CPU, where the at least one second CPU and the first CPU meet a preset condition associated with a relationship between the first CPU and the at least one second CPU, and sending second indication information to the first CPU topology, the second indication information instructing the first CPU topology to remove the first CPU and the at least one second CPU, resulting in a second CPU topology without the first CPU and other than the at least one second CPU.
