In one embodiment, the SAS/SATA stand grafting SAS/SATA hard disk, the IFDET_N pin and described
ACTIVITY pin is equal low level, and the controller controls the indicator light according to SGPIO signal and indicates disk state.
In one embodiment, the NVMe connector grafting NVMe hard disk, the IFDET_N pin are low level, institute
Stating ACTIVITY pin is high level, and the controller controls the indicator light according to I2C signal and indicates disk state.
In one embodiment, the indicator light includes Fault indicator light and Active indicator light.
In one embodiment, the controller is CPLD.
The second aspect of the utility model embodiment provides a kind of hard disk device, including above-mentioned hard disk indication lamp driving electricity
Road.
Above-mentioned disk drive circuit of indicator passes through setting SAS/SATA stand and NVMe connector, and in grafting SAS/
The indicator light is controlled according to SGPIO signal and I2C signal respectively when SATA hard disc and NVMe hard disk and indicates disk state, it can be with
The control signal of hard disk lamp is adaptively adjusted according to the different classes of hard disk of access.
Detailed description of the invention
It, below will be to embodiment or the prior art in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing needed in description is briefly described, it should be apparent that, the accompanying drawings in the following description is only that this is practical new
Some embodiments of type for those of ordinary skill in the art without any creative labor, can be with
It obtains other drawings based on these drawings.
Fig. 1 is hard disk indication lamp driving circuit structure schematic diagram provided by the embodiment of the utility model.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Referring to Fig. 1, the hard disk indication lamp driving circuit of application and hard disk device provided by the embodiment of the utility model, packet
Include controller, the indicator light connecting with the controller, SAS/SATA stand and NVMe connector, controller, SAS/SATA
Son and NVMe connector are arranged on backboard, and backboard connects being used for for hard disk device with NVMe connector by SAS/SATA stand
The mainboard of hard disk is installed.The IFDET_N pipe that controller passes through first and second, SGPIO signal wire connection SAS/SATA stand
Foot, ACTIVITY pin, SGPIO pin, controller also pass through third and fourth, I2C signal line connection NVMe connector
IFDET_N pin, ACTIVITY pin, I2C signal pin.Controller refers to according to the control of the SGPIO signal and I2C signal of access
Show that lamp indicates disk state.It should be noted that controller utilizes prior art parsing SGPIO signal and I2C signal.
In the present embodiment, controller is CPLD (Complex Programmable Logic Device, complex programmable
Logical device) indicator light includes Fault indicator light (orange lamp) and Active indicator light (blue lamp).In other embodiments
In, the color of indicator light can be selected arbitrarily, and the difference that can distinguish both Fault indicator light and Active indicator light then may be used.
In the present embodiment, SAS/SATA stand grafting SAS/SATA hard disk, IFDET_N pin (Pin4) and ACTIVITY
(Pin11) pin is equal low level, and controller indicates disk state according to SGPIO signal control instructions lamp.
Specifically, when being identified as SAS/SATA disk, controller parses the SGPIO signal for being input to backboard, each disk position
Respectively correspond parsing tri- kinds of signals of Active, Locate, error.Hard disk movable indicator light is controlled using Active signal,
Locate, error, Rebuild signal multiplexing control failure, positioning and reconstruction indicator light, SAS/SATA according to different frequencies
Hard disk indication lamp corresponding relationship is as follows:
In the present embodiment, NVMe connector grafting NVMe hard disk, IFDET_N pin is low level, and ACTIVITY pin is
High level, controller indicate disk state according to I2C signal control instructions lamp.Controller parses the I2C signal for being input to backboard,
Each disk position respectively correspond parsing two kinds of signals of error, Locate, Active modulating signal by hard disk itself Pin11
(ACTIVITY) pin goes to control.NVMe hard disk indication lamp is defined as follows table:
Blue lamp is controlled using Active signal, Locate combines four kinds of situations with error signal and goes to control orange lamp, respectively
It realizes the failure of hard disk lamp, positioning and Reconstruction of The Function, completes the signal control of NVME hard disk lamp.
Corresponding relationship is as follows:
Above-mentioned disk drive circuit of indicator passes through setting SAS/SATA stand and NVMe connector, and in grafting SAS/
Disk state is indicated according to SGPIO signal and I2C signal control instructions lamp respectively when SATA hard disc and NVMe hard disk, it can basis
Access the control signal that different classes of hard disk adaptively adjusts hard disk lamp.
