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, hard disc module can be chosen in the preferred embodiment has the situation of 4 hard disks, but 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 the hard disc module shown in Fig. 1, each hard disk is used for providing a read or write speed signal, and hard disk controller 1 is controlled these hard disks.In addition, hard disk backboard 2 is electrically connected hard disk controller 1, and comprises hard disk signal connector 10, multiple hard disk connector 201～204, multiple 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, in the time that the hard disk number in hard disc module is 4, hard disk connector 201～204 and display lamp 301～304 are correspondingly set.Specifically, hard disk backboard 2 is electrically connected hard disk controller 1 via hard disk signal connector 10.Hard disk connector 201～204 is electrically connected to respectively hard disk signal connector 10, and corresponding is electrically connected to hard disk separately, so that carry out exchanges data between hard disk controller 1 and hard disk.Administration module 40 is electrically connected to hard disk signal connector 10, receives by this hard disk signal connector 10 the read or write speed signal that hard disk provides separately, and is control signal by this read or write speed signal resolution.In addition, display lamp 301～304 is electrically connected to administration module 40, and the control signal parsing according to administration module shows respectively the read or write speed of hard disk separately.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 by display lamp 301.Similarly, display lamp 302 setting corresponding to hard disk connector 202, display lamp 303 setting corresponding to hard disk connector 203, display lamp 304 setting corresponding to hard disk connector 204.Thus, display lamp 301～304 is 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 light emitting diode, corresponding one by one with hard disk connector 201～204, for showing 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, to 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, i.e. the device of a managing access to data in physics and logic array can be checked the work of logical drive by it.The function of RAID controller both can be realized by hardware, software or the combination by hardware and software.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, for the port that hard disk backboard 2 is electrically connected to RAID controller is provided.In other embodiments, hard disk backboard 2 also can be electrically connected to this RAID controller by other means.
In another embodiment, hard disk signal connector 10 is a serial SCSI (Serial Attached SCSI; SAS) connector, wherein SAS is general-purpose interface, compatible SAS and S-ATA hard disk., according to the kind of hard disk connector, the hard disk connector 201～204 in this embodiment can be all SAS hard disk connector; Or be all S-ATA hard disk connector; Or a part is SAS hard disk connector, and another part is S-ATA hard disk connector.
In other embodiments of the invention, the read or write speed signal that hard disk provides can be the 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 SATA hard disk connector, when R/W speed of hard disc is 1.5G/s, this control signal correspondence is set to " 001 "; When R/W speed of hard disc is 3G/s, this control signal correspondence is set to " 010 "; When R/W speed of hard disc is 6G/s, this control signal correspondence is set to " 011 ".When hard disk is a SAS hard disk, and be electrically connected to SAS hard disk connector, R/W speed of hard disc is 3G/s, and this control signal correspondence is set to " 100 "; In the time that R/W speed of hard disc is 6G/s, this control signal correspondence is 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 ", LED display lamp is with the frequency scintillation of 2Hz; If control signal is " 010 ", LED display lamp is with the frequency scintillation of 4Hz; If control signal is " 011 ", LED display lamp is with the frequency scintillation of 6Hz; If control signal is " 100 ", LED display lamp is with the frequency scintillation of 5Hz; If control signal is " 101 ", LED display lamp is with the frequency scintillation of 7Hz.
Similarly, when hard disk is during in idle standby mode, no matter why type this hard disk hard disk, in administration module 40, be all set to control signal " 1 ", and now, LED display lamp presents normal bright state.
Thus, by hard disc module of the present invention, can, easily by the flicker frequency of the LED display lamp corresponding with hard disk and hard disk connector, demonstrate the duty of hard disk separately, and this hard disc module also can intuitively show the R/W speed of hard disc of hard disk connector in the time of work.
Although the present invention discloses as above by embodiment; but be not used for limiting the present invention; any those skilled in the art; without departing from the spirit and scope of the present invention; can make various changes and modification to the present invention, the scope that therefore protection scope of the present invention should define with claims is as the criterion.
