According to such scheme, by the pilot lamp be arranged on hard disk backboard is arranged on self hard disk pallet, when receiving the Target indication information that outside hard disk backboard sends, the pilot lamp be arranged on from is with it utilized to show, eliminate light-guiding pillar, and then improve the display effect of disk state.
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
As shown in Figure 3, embodiments provide a kind of disk state indicating means, the method is jointly performed by the mainboard of hard disk backboard, more than one hard disk and each hard disk pallet be fixed on by each hard disk on hard disk backboard and outside, and the method can comprise the following steps:
Step 301: reload signal connector on hard disk backboard, and on each hard disk pallet, install the signal contact plate be connected with signal connector respectively additional.
Due in existing scheme, the effect of hard disk pallet is only be fixed on hard disk backboard by hard disk, and hard disk pallet and hard disk backboard do not have the function of signal conduction.
And in the present embodiment, need hard disk backboard and hard disk pallet to carry out data interaction, therefore, can on hard disk backboard reload signal connector, and on each hard disk pallet, install the signal contact plate be connected with signal connector respectively additional.Wherein, signal connector can for having the shell fragment of conducting function or other have the connector of conducting function.
Step 302: the address information that each hard disk is set, and the indication information that each status information arranging hard disk is corresponding.
In the device architecture at the present embodiment place, including more than one hard disk, therefore, needing the address information by arranging hard disk to distinguish different hard disks.This arranges main body can be hard disk backboard, such as, the band EEPROM (Electrically Erasable Programmable Read Only Memo) on hard disk backboard (EEPROM, ElectricallyErasable Programmable Read-Only Memory) is utilized to arrange the address information of each hard disk and preserve.Further, owing to being connected by twin wire universal serial bus (I2C, Inter-Integrated Circuit) between hard disk backboard and the mainboard of outside, therefore, the address information arranging each hard disk can be I2C address.
Because the status information of hard disk can comprise: the one in state in place, error (mistake) state, active (effectively) state.Be the current state information of hard disk be any state to distinguish, therefore, the current state information of indication information to hard disk needing each status information by arranging hard disk corresponding is distinguished.
Wherein, indication information corresponding to each status information can be set by arranging mode such as instruction color or flicker frequency etc.Such as, the indication information arranging hard disk state in place is that pilot lamp shows green, and the indication information arranging the error state of hard disk is that pilot lamp display is red, and the indication information arranging the active state of hard disk is pilot lamp display blueness etc.Wherein, the indication information that each status information of the hard disk of setting is corresponding, can be stored in outside mainboard.
It should be noted that, the same state of each hard disk can use identical indication information to show, only need the hard disk pallet determining to need display disk state according to the address information of hard disk, without the need to arranging the indication information of each state respectively for each hard disk.
Step 303: the current state information of self, when determining that self generation state changes, is sent to the hard disk connecting circuit in hard disk backboard by hard disk.
In the present embodiment, the change of hard disk generation state can be: hard disk is connected power source, and now hard disk energising, so the current state information of hard disk is status information in place, and namely hard disk is changed to state in place by stateless.Or hard disk is changed to error state etc. by state in place.
In the present embodiment, hard disk backboard is connected with each hard disk by the hard disk connecting circuit of therein, when hard disk is when determining that self generation state changes, trigger self and send self current state information to the hard disk connecting circuit of hard disk backboard, wherein, the address information of hard disk is carried in current state information.
Step 304: the current state information of hard disk is sent to the mainboard connecting circuit of hard disk backboard by the hard disk connecting circuit of hard disk backboard.
Step 305: the current state information of hard disk is sent to outside mainboard by the mainboard connecting circuit of hard disk.
In the present embodiment, hard disk backboard comprises the mainboard connecting circuit be connected with hard disk connecting circuit, and mainboard connecting circuit is connected with outside mainboard, for the current state information of hard disk being sent to outside mainboard.
Wherein, the mainboard connecting circuit of hard disk backboard can be connected with mainboard by I2C.
Step 306: mainboard receives the current state information of the hard disk that mainboard connecting circuit sends, the indication information corresponding according to each status information of the hard disk stored, determines the Target indication information that current state information is corresponding.
In the present embodiment, mainboard can comprise: interconnective back panel connector and managing chip.Wherein, back panel connector is connected with the mainboard connecting circuit of hard disk backboard by I2C.When back panel connector receives the current state information of the hard disk that mainboard connecting circuit sends, the current state information of hard disk is sent to the managing chip of mainboard.The indication information that the managing chip of mainboard is corresponding according to each status information of the hard disk stored, determines the Target indication information that current state information is corresponding.
Wherein, motherboard substrate Management Controller (BMC, Baseboard Management Controller).
Step 307: Target indication information corresponding for the current state information determined is sent to the mainboard connecting circuit of hard disk backboard by mainboard by I2C, Target indication information carries the address information of hard disk.
Step 308: the Target indication information received is sent to signal connector by mainboard connecting circuit, signal connector reads the address information of target hard disk from EEPROM, determine the target hard disk pallet that target hard disk is corresponding, and Target indication information is sent to target hard disk pallet.
In the present embodiment, hard disk backboard also comprises: the signal connector be connected with mainboard connecting circuit, and information connector is connected with the signal contact plate on the pallet of hard disk.Signal connector, according to the address information of the hard disk carried in Target indication information, reads the address information of target hard disk, thus determines target hard disk pallet.
Step 309: the Target indication information that target hard disk pallet Received signal strength connector sends, according to Target indication information, the pilot lamp controlling to be arranged on self shows.
Owing to pilot lamp (LED) being arranged on hard disk backboard in prior art, also need to utilize the light-guiding pillar be arranged on hard disk pallet to carry out leaded light, and after light-guiding pillar leaded light, display effect is poor, therefore by being arranged on hard disk pallet by the pilot lamp be arranged on hard disk backboard, the pilot lamp making target hard disk pallet control to be arranged on self shows.Such as, Target indication information is that display is red, and so target hard disk pallet is lighted pilot lamp and shown redness.
