Abstract: An interconnection system including a first gating unit and a second gating unit is provided. The first gating unit includes two terminals, with one terminal connecting to a first CPU directly, where the two terminals are indirectly connected when the first gating unit is in a first state. The second gating unit includes two terminals, with one terminal connecting to a second CPU, where the two terminals are connected when the second gating unit is in the first state. Another terminal of the first gating unit is connected to another terminal of the second gating unit. If both the first gating unit and the second gating unit are in the first state, the first CPU is connected to the second CPU.

Abstract: 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.

Abstract: A method and an apparatus for triggering RAID reconstruction are disclosed, to achieve high universality and usability in triggering RAID reconstruction. The method includes: obtaining valid data information of a target storage medium after a change in storage mediums in a RAID is detected (S101); and reconstructing the RAID if the valid data information satisfies a preset reconstruction condition (S102).
