Mainboard, backboard, identification system and identification method

Abstract

The invention provides a mainboard, a backboard, an identification system and an identification method. The identification method comprises the following steps: acquiring and identifying hard disk port coding information by a PCH chip; enabling the PCH chip to configure the hard disk port coding information into address identification information; enabling the PCH chip to send the address identification information to a CPLD module through a mainboard connector and a backboard connector corresponding to the address identification information; and enabling the CPLD module to control the corresponding hard disk port working state lamp to act according to the address identification information. Therefore, the target hard disk can be accurately identified, and the specified hard disk working state lamp can be lighted up for identification. Misleading to use of a user and influencing work due to the fact that the hard disk working state lamp is not turned on accurately are avoided. And a dial switch is canceled in the connection process between the mainboard connector and the backboard connector, so the production efficiency is improved, the misoperation is reduced, and the maintenancecost is reduced. Product problems caused by wrong dialing due to misoperation are avoided.

Description

technical field [0001] The invention relates to the technical field of storage devices, in particular to a main board, a back board, an identification system and an identification method. Background technique [0002] With the continuous development of cloud computing, major Internet operators have more and more requirements for server product configuration, and the hard disk in server products is an indispensable component. [0003] At present, there are multiple connection ports on the SATA hard disk. When using it, it is necessary to determine which connection ports in the SATA hard disk to use. [0004] In order to determine which connection ports in the SATA hard disk to use, it is sufficient that the CPLD chip on the backboard can accurately perform lighting operations for the connection ports in the SATA hard disk. In the existing method, the connection ports in the SATA hard disk are distinguished in the following manner. [0005] The first way is through different...

This will increase the production cost of the backplane and increase the production process of the production line

And it is necessary to manually set the dial position of the dial switch and the connection port in the SATA hard disk, which will easily cause misoperation, so that the dial position of the dial switch does not correspond to the connection port in the SATA hard disk, which will affect the performance of the server hard disk. later use
