Abstract
The utility model provides a lamp controlgear is instructed to hard disk, the hard disk includes decoder chips, decoder chips includes the SGPIO bus, lamp controlgear is instructed to hard disk includes CPLD module and pilot lamp, input and the 11PIN of the trench of SGPIO bus, hard disk, the connected signal on the throne of hard disk of CPLD module, the output and the pilot lamp of CPLD module are connected. Adopt the technical scheme of the utility model, circuit structure is simple, and regardless of being windows operating system, or linux operating system can both be fine accomplishes the processing of lighting a lamp to have better compatibility.
Description
Technical field
This utility model relates to field of computer technology, particularly relates to a kind of hard disk indication lamp and controls device.
Background technology
In existing storage device or server storage product, producer all carries out visualization processing to SATA/SAS disk state, i.e. in place this of hard disk with which type of display lamp shows, hard disk movable state with which type of status lamp shows, hard disk occurs with which type of display lamp showing during mistake, which type of with display lamp show during the hard disk of location, also has other such as hard disc data reconstruction state etc., display lamp situation for compatible hard disk, each chip producer and equipment manufacturer: as Intel, HP, DELL, LSI, PMC etc., recommend SFF-8485/SFF8489 etc. and be specifically used to the consensus standard of compatible hard disk indication lamp situation.The most most of servers, storage device manufacturer realize hard disk lighting mode according to above-mentioned described SFF8485/SFF8489 agreement.
Most of manufacturer servers are as follows about the lighting mode realizing SATA/SAS hard disk:
(1) by the SGPIO of decoding chip, the situations such as hard disk movable instruction are defined according to SFF8485/SFF8489；
(2) but hard disk producer definition 11PIN as LED Activity indicate state PIN(Option), some equipment manufacturers just utilize P11 to carry out the process of hard disk movable display lamp；
But, above-mentioned both of which is defective, and such as in the 1st kind of mode, SGPIO can use below linux system, because there is the Driver increased income in face under linux, so being easily achieved SGPIO below linux system hard disk is carried out lighting.But below Windows system, Windows OS does not provide SGPIO to drive, this is accomplished by equipment manufacturer and carries out the Driver exploitation of SGPIO below Windows, it is known that exploitation needs Driver to expend the biggest human cost below Windows, and Windows system version is too many, compatibility to be accomplished is the most difficult.
The 2nd kind of above-mentioned mode is the most defective, particularly in SATA hard disc.Because in SATA protocol specification, hard disk producer about utilize 11PIN to carry out the display of hard disk Activity state, but this function is optional, is not required in that.Some SATA hard disc 11PIN can be used to lighting, and some SATA hard disc then do not have this function.If then utilizing 11PIN to carry out lighting, the hard disk Activity state instruction OK arisen that, the instruction of some hard disk Activity states is the most not all right.
Utility model content
For above technical problem, my utility model discloses a kind of hard disk indication lamp and controls device, uses simple circuit, no matter is Windows operating system, or (SuSE) Linux OS can well accomplish that lighting processes, and has more preferable compatibility.
To this, the technical solution of the utility model is:
A kind of hard disk indication lamp controls device, and described hard disk includes that decoding chip, described decoding chip include SGPIO bus, and described hard disk indication lamp controls device and includes CPLD(Complex Programmable Logic
Device, CPLD) module and display lamp, the input of described CPLD module is connected with SGPIO bus, the 11PIN of groove position of hard disk, the signal end in place of hard disk, and the outfan of described CPLD module is connected with display lamp.
This technical scheme, is judged by CPLD logical language, if CPLD detects SGPIO, signal has driving, then test represents below linux system, and test decoding SGPIO is used for each instruction state of some hard disk.Even if now the 11st PIN of hard disk has movable output, but is filtered out this activity instruction state by CPLD, because hard disk indication lamp can have been put by resolving SGPIO.If CPLD checks there is activity less than SGPIO, then can determine that it is now below Windows system or other system.CPLD logic can be by judging that the 11PIN of hard disk carries out hard disk movable display lamp process.Here have need explanation at 2: to have the hard disk of movable Activity instruction ability to original 11PIN, by this PIN of CPLD logic detection, then direct this PIN of transparent transmission or carry out some hard disk movable display lamps with 4HZ frequency in CPLD；If running into 11PIN there is no the hard disk of Activity instruction ability, need to judge on CPLD logic.The level of 11PIN is detected with CPLD, when hard disk is not read and write, record level state now；When hard disk is in read-write activity, record level state now.If judging that in CPLD logic now level changes, SGPIO is not detected again effectively driving simultaneously, can determine that below Windows system, and hard disk is in read-write, and the most now CPLD can carry out some hard disk movable display lamps with 4HZ or other frequency；Above two logic decision can solve below different system, the state of hard disk indication lamp.
As further improvement of the utility model, described SGPIO bus includes that SGPIO_SCK, SGPIO_SDATA, SGPIO_SLOAD, the input of described CPLD module are connected with SGPIO_SCK, SGPIO_SDATA, SGPIO_SLOAD.
As further improvement of the utility model, described display lamp includes that hard disk state indicator lamp, Hard disk error display lamp and hard disk positioning light, the outfan of described CPLD module are connected with hard disk state indicator lamp, Hard disk error display lamp, hard disk positioning light.
Preferably, described hard disk indication lamp controls device and is connected with SAS hard disk backboard, and described CPLD module is connected with SAS hard disk backboard.
Compared with prior art, the beneficial effects of the utility model are:
Using the technical solution of the utility model, circuit structure is simple, no matter is Windows operating system, or (SuSE) Linux OS can well accomplish that lighting processes, and has more preferable compatibility.
