Method for testing stability of high-frequency data transmission for server

The invention provides a method for testing the stability of high-frequency data transmission for a server. The communication bit error rate of key nodes through which high-frequency data passes when being transmitted in a server system is tested to detect whether the server system is designed reasonably or not and the running stability meets market requirements or not. The key testing node comprises a communication link between processors, a memory communication link and a PCIE (Peripheral Component Interconnect Express) high-speed expansion equipment communication link, wherein a data transmission node between the processors is responsible for data transmission between the processors, and a memory communication link node is responsible for data transmission between the processors and a memory; and a PCIE high-speed expansion equipment communication link node is responsible for data transmission between the processors/memory and PCIE high-speed expansion equipment. According to the method, the data transmission bit error rate of the communication link between processors, the memory communication link and the PCIE high-speed expansion equipment communication link is tested to validate whether the server runs stably or not under the condition of high-frequency data transmission.
