Abstract

The invention provides a method for detecting the corresponding relation between a hard disk backboard and a mainboard port, and the method comprises the steps that a programmable logic device on a mainboard generates and transmits N types of frequency signals to N connectors of the mainboard according to the corresponding relation between the frequency and the mainboard port, and the frequency signals, the mainboard port and the connectors are in one-to-one correspondence; the programmable logic device of the back plate receives a frequency signal sent by the back plate connector; according to the corresponding relationship between the frequency and the main board port; a corresponding relationship between the hard disk backboard and a mainboard port is determined. The invention further provides a device for detecting the corresponding relation between the hard disk backboard and the mainboard port, all port corresponding relation information can be transmitted, the problem that all possible port information cannot be transmitted to a hard disk backboard when current PCIe port information is transmitted is solved, the configuration mode can be more flexible, the efficiency is higher, and the number of occupied signal lines is reduced.

Description

technical field [0001] The invention relates to the field of hardware design, in particular to a method and a device for detecting the corresponding relationship between a hard disk backplane and a mainboard port. Background technique [0002] Currently in the server field, for NVMe (Non-Volatile Memory express, non-volatile memory host controller interface) hard disk directly connected to the PCIe (Peripheral Component Interconnectexpress, peripheral component interconnection interface) port of the motherboard CPU, the back of the hard disk The NVMe hard disk status indicators on the board are controlled by analyzing the lighting information sent by the CPU through the CPLD on the back panel. [0003] In order to correctly analyze the lighting signal, it is necessary to inform the backplane CPLD, the corresponding relationship between the NVMe hard disk and the PCIeport of the mainboard CPU. [0004] In the existing scheme, in order to notify the backplane CPLD of the corr...
