Abstract

The invention discloses a UPI signal interconnection device and an N-path server. When a processing module judges that CPU modules are in place and any two CPU modules in the in-place CPU modules are to be communicated, controllable switch modules corresponding to the in-place and to-be-communicated CPU modules are controlled to be switched on so as to realize data transmission; when it is judged that the CPU module is not in place, the controllable switch module corresponding to the CPU module which is not in place is controlled to be turned off, at the moment, for the CPU module which is in place, it is guaranteed that all the N UPI signal lines can be used for data transmission when the CPU module which is in place is in the to-be-communicated condition, the problem that in the prior art, UPI signal resources are wasted when the N CPU modules are not fully matched is solved, and the user experience is improved. And the data transmission throughput between the in-place CPUs to be communicated is improved.

Description

technical field [0001] The invention relates to the field of server design, in particular to a UPI signal interconnection device and an N-way server. Background technique [0002] The N-way server includes N CPUs (central processing unit, central processing unit), and each CPU includes N UPI (Ultra Path Interconnect, high-speed channel interconnection) signal transmission pins, and each CPU is connected to the UPI through the UPI signal transmission pins. The signal line is used to realize UPI signal interconnection, and N is 1 or an even number greater than 1. In the multi-channel server design, multiple CPUs and their UPI signal lines are all on the same main board, wherein at least one UPI signal line is connected between any two CPUs among the multiple CPUs to realize data transmission. The total number of UPI signal lines connected to each CPU is N. However, during the use of the multi-channel server, it is very likely that multiple CPUs are not fully allocated, that ...
