Abstract

The present invention provides a control method and system for a PCIE hard disk status light, comprising the following steps: judging the current working mode of a PCIE hard disk; CPU sending the current working mode information to a south bridge chip; The working mode information is sent to the complex programmable logic controller; according to the current working mode information, the complex programmable logic controller controls the display of the status light corresponding to the current working mode. The control method of the PCIE hard disk status light and the system CPU of the present invention control the CPLD through the south bridge chip, thereby realizing the display control of the status light corresponding to the reset and positioning operations of the PCIE hard disk; the use state of the PCIE hard disk can be judged in time; Hamming verification is performed on the current working mode information to ensure the accurate display of the status light.

Description

technical field [0001] The invention relates to the technical field of PCIE solid-state hard disks, in particular to a control method and system for a status light of a PCIE hard disk. Background technique [0002] At present, most servers use SATA / SAS 6G hard drives, and a small part use SATA / SAS 12G hard drives. Such as figure 1 As shown, when controlling the status light display of the SATA / SAS 6G / 12G hard disk, the CPU is connected to the SAS expander (SAS Expander) through the SAS controller, and the SAS Expander connects the signal to the SFF-8639 connector, and then the SFF The -8639 connector is connected to an external SATA / SAS 6G / 12G hard disk, so that the CPU can control the signal light of the SATA / SAS 6G / 12G hard disk. Specifically, the tool on the system side issues commands to the CPU side, and the CPU controls the SAS Expander through the SAS controller to send a serial input and output (Small General Purpose Input Output, SGPIO) signal to a complex program...
