Abstract

The invention provides a method for controlling a peripheral component interface express (PCIE) hard disk status lamp and a system, which comprises steps: the current work mode of a PCIE hard disk is judged, a central processing unit (CPU) sends current work mode information to a south bridge chip, the south bridge chip sends the current work mode information to a complex programmable logic controller, and the complex programmable logic controller controls a status lamp corresponding to the current work mode to display according to the current work mode information. The method for controlling the PCIE hard disk status lamp and the system control complex programmable logic device (CPLD) through the south bridge chip, and further achieves to control display of the status lamp corresponding to return and positioning operation of the PCIE hard disk. The method for controlling the PCIE hard disk status lamp and the system can judge the use state of the PCIE hard disk in time, and guarantees the status lamp to be accurately displayed by hamming and verifying the current work mode information.

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 / SAS6G hard disks, and a small part use SATA / SAS12G hard disks. Such as figure 1 As shown, when controlling the status light display of the SATA / SAS6G / 12G hard disk, the CPU is connected to the SAS expander (SASExpander) through the SAS controller, and the SASExpander connects the signal to the SFF-8639 connector, and then the SFF-8639 connects The controller is externally connected to a SATA / SAS6G / 12G hard disk, so that the CPU can control the signal lights of the SATA / SAS6G / 12G hard disk. Specifically, the tool on the system side issues commands to the CPU side, and the CPU controls the SASExpander to send a serial input and output (Small General Purpose Input Output, SGPIO) signal to the complex programmable logic device (Comp...
