Abstract

The invention provides a CPU interconnection device and multi-channel server CPU interconnection topology, the CPU interconnection device includes: two NC chips and four CPUs, wherein, the CPU has a QPI bus interface, and the NC chip has a QPI bus interface and NI bus Interface; according to the QPI link, the four CPUs are sequentially connected into a four-way configuration structure, and one NC chip is connected to any adjacent two CPUs, and the other NC chip is connected to the other two CPUs. In addition to the QPI link, according to the NI line corresponding to the NI bus interface, the NC chip can be used as a medium to realize the communication between any two CPUs, and the number of NC chips is not limited. Since the pairwise connection between CPUs is no longer limited to the QPI link, this solution can enable multiple CPUs of more servers to be interconnected by using a certain number of such CPU interconnection devices.

Description

technical field

[0001] The invention relates to the technical field of computers, in particular to a CPU interconnection device and a multi-path server CPU interconnection topology. Background technique

[0002] In key business industries such as finance and telecommunications, the basic requirements for server computing speed and shared memory are relatively high. Multi-channel servers, such as eight-channel servers and sixteen-channel servers, can not only meet these basic requirements, but also hold great advantages in database applications and cloud computing.

[0003] Currently, multiple CPUs of a multi-channel server can be connected through QPI direct connection.

[0004] However, due to the limited number of QPI links of the CPU itself, the existing connection method cannot interconnect multiple CPUs of more servers. Contents of the invention
