Fig. 1 is present system structural representation；
Fig. 2 is the inventive method flow chart schematic diagram.
Embodiment
For the technical characterstic for illustrating this programme can be understood, below by embodiment, and its accompanying drawing is combined, to this hair
It is bright to be described in detail.Following disclosure provides many different embodiments or example is used for realizing the different knots of the present invention
Structure.In order to simplify disclosure of the invention, hereinafter the part and setting of specific examples are described.In addition, the present invention can be with
Repeat reference numerals and/or letter in different examples.This repetition is that for purposes of simplicity and clarity, itself is not indicated
Relation between various embodiments are discussed and/or set.It should be noted that part illustrated in the accompanying drawings is not necessarily to scale
Draw.Present invention omits the description to known assemblies and treatment technology and process to avoid being unnecessarily limiting the present invention.
As shown in figure 1, a kind of server hard disc indicator lamp design system of compatible NVME hard disks, including server hard disc,
Hard disk indication lamp, CPLD modules, SGPIO controllers and VPP controllers, server hard disc includes NVME hard disks and SAS/SATA is hard
Disk, SGPIO controllers are connected by SGPIO buses with CPLD modules, and VPP controllers export PCA9555 by I2C buses and controlled
To the input of CPLD modules, the PCA9555 that CPLD module simulations go out communicated signal by I2C buses with VPP controllers.
Hard disk indication lamp includes locate indicator lamps (blueness), fault indicator lamps (yellow) and act indicator lamps (green), act indicator lamps
It is connected with server hard disc, locate indicator lamps, fault indicator lamps are connected with CPLD respectively.
CPUVPP controllers are the control for being used for standard PCIE device hot plug control that intel platforms CPU is internally integrated
Logic, NVME hard-disk interfaces are exactly physically PCIE interfaces, so the present invention is exactly to be used as NVME hard disks by the use of VPP controllers
LED light control logic；SGPIO controllers are the controllers of traditional SAS/SATA hard disk LED configured informations；CPLD modules
It is responsible for the control of all hard disk LED indicator lamps and the differentiation of hard-disk interface type；LED controller circuit is hard disk LED indicator lamp
Direct control logic.
As shown in Fig. 2 a kind of server hard disc indicator lamp design method of compatible NVME hard disks, comprises the following steps：
S1, judge whether hard disk in place and hard disk type step；Hard disk type is SAS/SATA hard disks, jumps to step
S2, judge that hard disk for NVME hard disks, jumps to step S3；
S2, SGPIO controller send control signals to CPLD modules, control hard disk indication lamp；
S3, VPP controller send control signals to PCA9555, control hard disk indication lamp.
Step S1 includes：
The first step, CPLD first detect signal present in place on hard-disk interface, if present is low, in explanation system
There is insertion hard disk；
Second step, CPLD judge IFDET (hard-disk interface type) signal, if IFDET is height, just press SGPIO specification solutions
Phase separation closes LED control logics corresponding to disk state；If step-down illustrates that the hard disk of insertion is NVME hard disks, CPLD will not be parsed
SGPIO information, CPLD can fictionalize PCA9555 interface equipment, response VPP addressing.
Step S2 comprises the following steps：The state of three signals is issued CPLD, SGPIO data-signals by SGPIO controllers
It is upper can order embody act/locate/fault, the second hard disk act/locate/fault of first hard disk, altogether 8 it is hard
Disk information, CPLD parse relevant information again, by three LED actions of mechanism control in table 1.
| Hard disk is read | Hard disk positions | Hard disk is from group | Hard disk error | |
| ACT | Green flicker | Green flicker | Green flicker | Go out |
| LOCATE | Go out | Blue 4HZ flickers | Blue 1HZ flickers | Go out |
| FAULT | Go out | Go out | Go out | It is red bright |
Table 1, conventional hard indicator lamp control information
VPP controllers are by I2C output control PCA9555 output correlation signals, 8 signals of output are always met together, such as table 2
It is shown, wherein PWREN (power supply), button (button detecting), PWRFALT (power supply mistake), MRL (Structural lock), EMIL
(interruption) these signals present invention need not be related to, and due to not including hard disk ACT information in VPP, we are straight by ACT indicator lamps
Hard disk is connected in succession, and hard disk movable signal ACT is directly controlled by hard disk；Because VPP needs present (hard disk is in place), we
Hard disk is signally attached to CPLD in place.
Step S3 comprises the following steps：CPLD by virtual PCA9555 by Present (in place) information (8 data,
4th is 0) to be supplied to VPP controllers by I2C buses；VPP controllers receive present signals (the 4th be 0), will be to
Virtual PCA955 sends ATNLED (early warning) and PWRLED (health) information (0 of 8 data and 1), and CPLD is received
PCA955 sends ATNLED and PWRLED information will be parsed locate (positioning), fault (mistake) LED behaviors by table 3.
| PCA955 signals | Direction | Remarks | |
| 0 | ATNLED | Output | |
| 1 | PWRLED | Output | |
| 2 | PWREN | Output | Without using |
| 3 | BUTTON | Input | Without using |
