Embodiment

Fig. 1 illustrates according to a preferred embodiment of the present invention, the block diagram of hard disc module.With reference to Fig. 1, in order to show the reading and writing data speed of hard disk, hard disc module of the present invention comprises: at least one hard disk (not shown), hard disk controller 1 and hard disk backboard 2.Those of ordinary skill in the art is to be understood that; This hard disc module can comprise one or more hard disks; For ease of schematically explanation, for example, can in the preferred embodiment, choose the situation that hard disc module has 4 hard disks; Yet the hard disk situation of other number also within the scope of the invention, and the present invention has more than the situation that is confined to 4 hard disks.

In hard disc module shown in Figure 1, each hard disk is used to provide a read or write speed signal, and hard disk controller 1 is controlled these hard disks.In addition, hard disk backboard 2 electrically connects hard disk controller 1, and comprises hard disk signal connector 10, a plurality of hard disk connector 201～204, a plurality of display lamp 301～304 and administration module 40.Be not difficult to find out, in the present embodiment, as previously mentioned, hard disk connector and display lamp quantity separately all with the corresponding setting of number of hard disk, when the hard disk number in the hard disc module is 4, hard disk connector 201～204 and display lamp 301～304 are set correspondingly.Specifically, hard disk backboard 2 electrically connects hard disk controller 1 via hard disk signal connector 10.Hard disk connector 201～204 is electrically connected to hard disk signal connector 10 respectively, and corresponding is electrically connected to hard disk separately, so that between hard disk controller 1 and hard disk, carry out exchanges data.Administration module 40 is electrically connected to hard disk signal connector 10, receives the read or write speed signal that hard disk provided separately through this hard disk signal connector 10, and is control signal with this read or write speed signal resolution.In addition, display lamp 301～304 is electrically connected to administration module 40, and the control signal that parses according to administration module shows the read or write speed of hard disk separately respectively.Preferably, for a certain hard disk, this hard disk is electrically connected to hard disk connector 201, and shows the read or write speed of this hard disk through display lamp 301.Similarly, display lamp 302 and hard disk connector 202 corresponding settings, display lamp 303 and hard disk connector 203 corresponding settings, display lamp 304 and hard disk connector 204 corresponding settings.Thus, display lamp 301～304 is used for showing respectively the reading and writing data speed of the hard disk of the hard disk connector electric connection corresponding with it.In addition, display lamp 301～304 can be a light emitting diode, and is corresponding one by one with hard disk connector 201～204, is used to show the reading and writing data speed of hard disk separately.For example, LED can be according to glimmering according to different frequency from the control signal of administration module 40, so that show the reading and writing data speed speed of the hard disk corresponding with it.

In one embodiment, hard disk controller 1 can be a RAID controller, and promptly the device of a managing access to data in physics and logic array can be checked the work of logical drive through it.The function of RAID controller both can by hardware, software or through hardware and software combine realize.For example, hard disk controller 1 can be the RAID controller of a combined with hardware and software function.Preferably, this RAID controller can also comprise a connectivity port, is used to provide the port that hard disk backboard 2 is electrically connected to the RAID controller.In other embodiments, hard disk backboard 2 also can be electrically connected to this RAID controller through other modes.

In another embodiment, hard disk signal connector 10 is a serial SCSI (Serial Attached SCSI; SAS) connector, wherein SAS is a general-purpose interface, compatible SAS and S-ATA hard disk.Then according to the kind of hard disk connector, the hard disk connector 201～204 among this embodiment can all be the SAS hard disk connector; Or all be the S-ATA hard disk connector; Or a part is the SAS hard disk connector, and another part is the S-ATA hard disk connector.

Administration module 40 electrically connects with hard disk signal connector 10; Be used for being received from the R/W speed of hard disc signal of hard disk controller 1 output through hard disk signal connector 10; And be control signal with this read or write speed signal resolution, to be used for controlling the flicker frequency of LED display lamp.For example, administration module 40 can be the module of software, hardware, circuit and combination thereof, or PLD (Complex Programmable Logic Device; CPLD) and other field programmable gate arrays (Field-Programmable Gate Array; FPGA).In the preferred embodiment; Administration module 40 is PLDs; Can communicate by letter with hard disk controller 1 or carry out exchanges data through hard disk signal connector 10, and can be through the general I/O of serial (Serial General purpose input/output between administration module 40 and the hard disk controller 1; SGPIO) signal communication or carry out exchanges data.For example, be that a string working used input/output signal from the read or write speed signal of hard disk, i.e. SGPIO signal.More particularly, when administration module 40 was control signal with this SGPIO signal resolution, the control signal of being resolved was a parallel signal.

In other embodiments of the invention, the read or write speed signal that hard disk provided can be a signal of supporting other communication modes or form, and the control signal that administration module 40 is resolved can be the control signal of other types, for example, and clock control signal.At this moment, in administration module 40, when hard disk is a SATA dish, and be electrically connected to the SATA hard disk connector, when R/W speed of hard disc was 1.5G/s, then this control signal correspondence was set to " 001 "; When R/W speed of hard disc is 3G/s, then this control signal correspondence is set to " 010 "; When R/W speed of hard disc is 6G/s, then this control signal correspondence is set to " 011 ".When hard disk is a SAS hard disk, and be electrically connected to the SAS hard disk connector, R/W speed of hard disc is 3G/s, and then this control signal correspondence is set to " 100 "; When R/W speed of hard disc was 6G/s, then this control signal correspondence was set to " 101 ".

So, LED display lamp 301,302,303 and 304 glimmers according to different frequency according to clock control signal.For example, when control signal is " 001 ", then the LED display lamp is with the frequency scintillation of 2Hz; Like control signal is " 010 ", and then the LED display lamp is with the frequency scintillation of 4Hz; Like control signal is " 011 ", and then the LED display lamp is with the frequency scintillation of 6Hz; Like control signal is " 100 ", and then the LED display lamp is with the frequency scintillation of 5Hz; Like control signal is " 101 ", and then the LED display lamp is with the frequency scintillation of 7Hz.

Likewise, when hard disk was in idle standby mode, no matter why type this hard disk hard disk in administration module 40, all was set to control signal " 1 ", and at this moment, the LED display lamp presents normal bright state.

Thus; Through hard disc module of the present invention, can demonstrate the duty of hard disk separately easily through the flicker frequency of the LED display lamp corresponding with hard disk and hard disk connector; And this hard disc module also can intuitively show the R/W speed of hard disc of hard disk connector when work.

Though the present invention discloses as above through embodiment; But be not to be used for limiting the present invention; Any those skilled in the art; Do not breaking away from the spirit and scope of the present invention, can make various changes and modification, so protection scope of the present invention should be as the criterion with the scope that claims define the present invention.
