Serial port hard disk lighting method based on input/output controller center

Abstract

The invention provides a serial port hard disk lighting method based on an input / output controller center, and relates to the technical field of computers. The input / output controller is provided withsix universal input and output pins and three serial interfaces. The serial port hard disk lighting method comprises the following steps: S1, connecting first, second and third universal input and output pins at the center of the input and output controller into an error reporting signal, and connecting fourth, fifth and sixth universal input and output pins at the center of the input / output controller to a positioning signal; S2, respectively connecting the six universal input and output pins with three serial interfaces; S3, connecting the six universal input and output pins to a complex programmable logic device, and simultaneously connecting the effective signals of the positions of the active signal pins of the three serial port hard disks and the positioning signals of the three serial port hard disks to the complex programmable logic device; and S4, decoding the accessed signal by the complex programmable logic device, and outputting a corresponding signal to light an LED indicating lamp of the hard disk to display the working state of the corresponding hard disk.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to a lighting method for a serial port hard disk based on an input-output controller center. Background technique [0002] The hard disk lighting function of the server has three major uses, which are to check the normal working status of the hard disk, check whether the hard disk has an error, and locate the location of the hard disk, which is often called active (Active), error (Fault) and location (Locate). [0003] At present, the industry is using the SFF-8485 SGPIO protocol (serial General-Purpose IO ports, a serial general-purpose input and output interface) to control the different states of the indicator light for decoding to implement the lighting function of the hard disk. The SFF-8485 SGPIO protocol is referred to as SGPIO protocol, through the SGPIO protocol, the LED positioning function of the hard disk and the LED indication function of the faulty hard disk can be...

Problems solved by technology

Take the second-generation I / O controller center (ICH2 set) produced by Chengdu Shenwei Technology Co., Ltd. as an example. It does not integrate the SFF-8485 SGPIO protocol interface, so the SGPIO interface cannot be used to decode the work of the three SATA hard disks. State, that is, the conventional SGPIO protocol method cannot be used to realize the hard disk lighting function under the second-generation input and output controller center (ICH2 chip)

The second-generation input and output controller center (ICH2 chip set) only has the single function of outputting activity indicators, and cannot realize the functions of locating the location of the hard disk and viewing the indicator lights of the hard disk error report.

If there is a problem with one of the hard disks, it cannot be intuitively reflected by the hard disk indicator light on the appearance, nor can the hard disk be replaced or maintained by directly locating a certain hard disk, which brings a great impact on the maintenance and operation of the product. inconvenient
