Self-adaptive configuration method and system for M.2 hard disks on server boards

Abstract

The invention discloses a self-adaptive configuration method and system for M.2 hard disks on server boards. The method comprises the following steps of: 1, setting a PCH high-speed interface module between a CPU and an M.2 interface module; 2, acquiring the state of the 69th PIN of the M.2 interface module; 2, judging the type of an accessed M.2 hard disk according to the state information of the 69th Pin; and 4, configuring a PCH high-speed interface according to the type of the M.2 hard disk. The system comprises the PCH high-speed interface module, the M.2 interface module and a self-adaptive configuration module, wherein the PCH high-speed interface module is connected with a server CPU through a DMI bus; the M.2 interface module and the self-adaptive configuration module are respectively connected with the PCH high-speed interface module; and the M.2 interface module is connected with the M.2 hard disk. According to the method and system, different M.2 hard disks can be automatically recognized, the design difficulty is reduced and the cost is reduced.

Description

technical field [0001] The invention relates to an adaptive configuration method and system for an M.2 hard disk on a server board, belonging to the technical field of servers. Background technique [0002] With the widespread application of computer information technology, there are massive amounts of data that need to be processed and stored in human society. Therefore, the rapid development of information technology has put forward higher requirements on the performance of storage systems. At present, the capacity of computer storage systems has been greatly improved, but there is still a bottleneck in the data transmission rate of traditional disk storage. For this reason, solid-state hard disk technology came into being. Solid-state hard disk caters to the development trend of information storage. Compared with traditional disk systems, it has the advantages of faster unit read and write speed, lower energy consumption, and stronger mobile reliability. . [0003] With...

AI Technical Summary

Problems solved by technology

[0006] There are two channels of PCIE and SATA in the market, because there are some multiplexed pins on the pins occupied by the two on the M.2 connector, so there is no way to directly connect the two together to achieve compatibility with the two hard drives

[0007] The problem brought about by this is that the needs of current customers for M.2 disks are not consistent, and there is a big difference in the cost of the two. How to make one motherboard compatible with both requirements has become a challenge for the current server motherboard design.
