Abstract

The present invention proposes a multi-channel server PECI link control system based on FPGA, comprising: several server nodes, header connectors and FPGA, wherein the FPGA includes a first switching module, a second switching module, and a partition detection control module. Described the first switching module is communicated with the CPU of the corresponding server node through the first PECI link, the first switching module is communicated with the BMC of the corresponding server node through the second PECI link, and the second switching module is respectively Connect with several first switching modules; the header connector is used to set the number of partitions; the partition detection control module is used to control the channel switching of the first switching module and the second switching module according to the number of partitions, so as to realize the number of multiple server partitions. The switching settings and the corresponding PECI link improve the stability and reliability of the PECI link control of the multi-channel server.

Description

technical field [0001] The invention relates to the field of server PECI link control, in particular to an FPGA-based multi-channel server PECI link control system. Background technique [0002] With the development needs of application scenarios such as cloud platforms, high-performance computing, and heterogeneous computing, customers pay more attention to the flexible design requirements of multi-channel server systems, that is, to achieve rapid modification of the entire system through the reuse of key modules. At present, the mainstream multi-way servers are usually 8-way or 4-way. Usually, the multi-way server system needs to meet the partition switching function. For example, an 8-way server system can be split into two 4-way server systems or four A 2-way server system. No matter how the multi-channel server system is partitioned, the real-time detection of the temperature during the operation of each CPU (Central Processing Unit, central processing unit) is an impo...
