The mixed insertion hard disk lamp signal control method according to claim 6, wherein the hard disk backplane judges the type of the currently used hard disk by the built-in hard disk backplane CPLD chip according to the lamp signal state data and the hard disk type identification look-up table, including,
after the back plate CPLD chip receives the data, the package analysis is carried out through a built-in UART receiving module, and the hard disk indicator light states of a VPP signal and an SGPIO signal are obtained after the package analysis;
and judging the currently used hard disk Type according to the hard disk Type identification comparison table by utilizing a built-in HDD Type Detection module.
8. The method for controlling lamp signals of a mixed insertion hard disk according to claim 5, wherein the determining the output signals of the lamp signals according to the judgment result comprises:
if the judgment result is that the current SAS hard disk is used, the current lamp number is controlled by the SGPIO signal;
and if the judgment result is that the currently used NVME hard disk is used, the current lamp number is controlled by the VPP signal.
9. The utility model provides a mix and insert hard disk lamp signal controlling means which characterized in that includes:
the memory is used for storing the mixed insertion hard disk lamp signal control program;
a processor, configured to implement the steps of the hybrid hard disk lamp control method according to any one of claims 5 to 8 when executing the hybrid hard disk lamp control program.
10. A readable storage medium, characterized by: the readable storage medium stores a mixed-insertion hard disk lamp control program, and the mixed-insertion hard disk lamp control program realizes the steps of the mixed-insertion hard disk lamp control method according to any one of claims 5 to 8 when executed by a processor.
