Background
In a region where a network is developed, a lot of information has been stored on public nodes of the network so that a depositor himself or a related person or the like can easily obtain necessary information through the network. These publishing nodes, which are used to store information, are typically comprised of one or more file servers. A file server can be generally divided into two parts, one of which is a management part, i.e. a processor within the file server and a file management system operating in the processor, and the other of which is a data storage part, i.e. a hard disk. The data storage part is less costly to build than the management part. Therefore, in order to achieve the purpose of storing a large amount of information and easy management with less cost, each file server is usually connected to as many hard disks as possible to manage and access the most data through the minimum management system.
Therefore, in a storage device used as a file server, there are many hard disks at the same time. Once the storage device is required to be turned on, all the hard disks in the storage device are turned on simultaneously. Since a large start-up current is required when the hard disks are turned on, once all the hard disks are turned on simultaneously, a large current surge is generated at this moment. The current surge is liable to cause unrecoverable damage to the power supply and related connecting circuits, thereby reducing the reliability of the storage device and the entire file server.

Detailed Description
Please refer to fig. 1, which is a block diagram of a multi-hard disk storage device according to an embodiment of the present invention. The multi-hard disk storage device 10 of the present embodiment can access four hard disks 130A, 130B, 130C and 130D, and includes an interface control board 100, a bottom board 110, and four hard disk controllers 120A, 120B, 120C and 120D. The hard disk controller 120A controls the operation (for example, reading or writing) of the hard disk 130A, the hard disk controller 120B controls the operation of the hard disk 130B, the hard disk controller 120C controls the operation of the hard disk 130C, and the hard disk controller 120D controls the operation of the hard disk 130D. Furthermore, each of the hard disk controllers 120A, 120B, 120C and 120D is an independently operating circuit, such as a System on Chip (SoC) or a circuit board. When the hard disk controllers 120A, 120B, 120C, and 120D are turned off, the corresponding controlled hard disks 130A, 130B, 130C, and 130D will stop operating; when the hard disk controllers 120A, 120B, 120C, and 120D are turned on, the corresponding controlled hard disks 130A, 130B, 130C, and 130D start to start and enter a normal operation state. In the present invention, each hard disk controller may be implemented entirely as a chip or entirely as a circuit board, or may be implemented partly as a chip and partly as a circuit board.
In the present embodiment, the interface control board 100 determines the control signals C1, C2, C3 and C4 to be output according to the received DATA, and is electrically coupled to the bottom board 110 through the signal bus 105 to provide the control signals C1, C2, C3 and C4 to the corresponding control lines 112A, 112B, 112C and 112D, respectively. The control lines 112A, 112B, 112C and 112D are disposed on the bottom plate 110 and are designed to allow electrical coupling with the interface control board 100; in addition, the control lines 112A are designed to allow electrical coupling to the hard disk controller 120A, the control lines 112B are designed to allow electrical coupling to the hard disk controller 120B, the control lines 112C are designed to allow electrical coupling to the hard disk controller 120C, and the control lines 112D are designed to allow electrical coupling to the hard disk controller 120D. In cooperation with the signal bus 105, the control line 112A may transmit the control signal C1 from the interface controller board 100 to the hard disk controller 120A, the control line 112B may transmit the control signal C2 from the interface controller board 100 to the hard disk controller 120B, the control line 112C may transmit the control signal C3 from the interface controller board 100 to the hard disk controller 120C, and the control line 112D may transmit the control signal C4 from the interface controller board 100 to the hard disk controller 120D. From another perspective, the interface control board 100 may transmit the control signals C1, C2, C3 and C4 to the hard disk controllers 120A, 120B, 120C and 120D, respectively, so as to control whether the hard disk controllers 120A, 120B, 120C and 120D should be turned on or off according to the control signals C1, C2, C3 and C4.
It is noted that the above embodiment performs the on and off control in units of one hard disk controller, that is, the hard disk controller is divided into four groups for performing the on and off control, and each group includes one hard disk controller. This is not a necessary limitation of the present technology. In contrast, the present invention provides a technique that can change the number of hard disk controllers that can be controlled at a time according to actual needs.
Fig. 2 is a circuit block diagram of a multi-hard disk storage device 20 according to another embodiment of the present invention. In this embodiment, the same elements as those in fig. 1 denoted by the same element numbers indicate that the functions of the elements are similar to those in fig. 1, and thus are not described herein again. In the present embodiment, the difference from the previous embodiment is that the interface control board 100 only uses two control signals C5 and C6 to control the on/off of the four hard disk controllers 120A, 120B, 120C and 120D. From another perspective, the four hard disk controllers 120A, 120B, 120C, and 120D are divided into two groups G1 and G2. The control signal C5 is transmitted from the interface control board 100 to the hard disk controllers 120A and 120B via the signal bus 105 and the control line 112E provided on the backplane, so as to control whether to turn on or off the hard disk controllers 120A and 120B at the same time; similarly, the control signal C6 is transmitted from the interface control board 100 to the hard disk controllers 120C and 120D via the signal bus 105 and the control line 112F disposed on the backplane, so as to control whether to turn on or off the hard disk controllers 120C and 120D at the same time. Therefore, the purpose of opening or closing the hard disk by the partition control can be realized by taking the two hard disk controllers as a unit.
Of course, each group need not be limited to containing only the above number of hard disk controllers, nor must it be limited to containing the same number of hard disk controllers. In fact, each group may contain at least one hard disk controller, and the number of hard disk controllers contained need not be the same as the number of hard disk controllers contained in other groups.
The structure of each element and its composition will be described in detail below. Please refer to fig. 3, which is a diagram illustrating a hard disk controller according to an embodiment of the present invention. In the present embodiment, the hard disk controller 310 is locked with the corresponding screw hole 3010 of the hard disk 300 by using a screw (not shown). The hard disk controller 310 is a circuit board and has a gold finger 3110 adapted to be inserted into the slot to receive and transmit electronic signals from and to the hard disk controller 310, or transmit electronic signals in the hard disk controller 310 to the outside.
Please refer to fig. 4A, which is a schematic diagram of a combination structure of a backplane and a hard disk controller according to an embodiment of the present invention. In this embodiment, a plurality of storage unit connectors 410 (only three shown), a controller board connector 420, a light group 430, a plurality of memory modules 440 (only one shown), a plurality of data lines 4112 (only one shown), a plurality of control lines 4212 (only one shown), a plurality of first status data lines 4114 (only one shown), a plurality of second status data lines 4216 (only one shown), and a plurality of light control lines 4214 (only one shown) are disposed on the backplane 400. In order to cooperate with the hard disk 300 and the hard disk controller 310 shown in fig. 3, each storage unit connector 410 includes a hard disk connection port 4100 and a controller connection port 4110, the hard disk connection port 4100 and the controller connection port 4110 are both made into circuit board slots suitable for inserting the hard disk 300 and the hard disk controller 310, and the hard disk connection port 4100 and the controller connection port 4110 use circuit traces to implement signal transmission, so that electronic signals can be transmitted between the hard disk connection port 4100 and the controller connection port 4110. After the hard disk 300 and the hard disk controller 310 are locked together as shown in FIG. 3, the hard disk 300 may be inserted into the hard disk connection port 4100 and the hard disk controller 310 may be inserted into the controller connection port 4110. In this way, the hard disk controller 310 can control the hard disk 300 by using the controller connection port 4110, the hard disk connection port 4100 and the circuit connected between the two connection ports. In other words, the hard disk 300 and the hard disk controller 310 locked together do not directly perform signal transmission, but perform signal transmission between them through the hard disk connection port 4100, the controller connection port 4110, and the circuit traces provided on the backplane 400. In another embodiment, the hard disk controller 310 may be a chip integrated on the backplane 400, the controller connection port 4110 is not required in the storage unit connector 410, and the hard disk controller 310 realizes signal transmission between the hard disk controller and the hard disk connection port 4100 through circuit traces therebetween.
In the present embodiment, the backplane board 400 is electrically coupled to the interface control board 100 shown in fig. 1 through the control board connector 420. Specifically, in the present embodiment, the control board connector 420 includes a power connection port 4200 and an interface control board connection port 4210, and the power connection port 4200 is connected to a power supply (not shown) to receive and transmit power to the electronic components disposed on the backplane board 400, or further to provide power to the electronic components electrically coupled to the backplane board 400. The interface board connection port 4210 is adapted to be directly coupled to the signal bus 105 shown in fig. 1, or may be directly coupled to the interface board 100 shown in fig. 1 (i.e., the signal bus 105 is omitted). In general, the control signals C1, C2, C3 and C4 generated by the interface control board 100 can be transmitted from the interface control board 100 to the corresponding controller connection port 4110 and further to the corresponding hard disk controller 310 via the interface control board connection port 4210 and the control line 4212 connected between the interface control board connection port 4210 and the controller connection port 4110. It should be noted that only one control line 4212 is shown for simplicity, but in this embodiment, a control line is provided on the backplane 400 for each storage unit connector 410, and each such control line is independent and does not intersect with control lines controlling other hard disk controllers.
In the embodiment shown in FIG. 4A, the control signals C1-C4 may control the corresponding hard disk controller 310 to turn on or off, respectively. Once controlled to be off, power is not provided to the hard disk controller 310 and the hard disk 300 controlled by the hard disk controller 310. In another embodiment, referring to FIG. 4B, control signals C1-C4 can also be provided to switch 4120 in storage cell connector 410 via control line 4212 to control whether switch 4120 is turned on. Once the switch 4120 is turned off, power is not provided to the corresponding storage unit connector 410, and the hard disk controller 310 and the hard disk 300 coupled to the storage unit connector 410 stop operating because no power is supplied. In contrast, if the switch 4120 is turned on, power is supplied to the corresponding storage unit connector 410 (e.g., via a power line not shown), and the hard disk controller 310 and the hard disk 300 coupled to the storage unit connector 410 start to operate due to the power supply.
Please return to fig. 4A. In the present embodiment, a plurality of data lines 4112 are electrically coupled between each of the hard disk connection ports 4100 and the interface control board connection port 4210 (for simplicity and clarity, only one of the data lines 4112 is shown in the figure); thereby, the data line 4112 may transfer data between the hard disk 300 and the interface control board under the control of the hard disk controller 310. In addition, a plurality of first status data lines 4114 are electrically coupled between each controller connection port 4110 and the corresponding memory module 440 (for simplicity and clarity, only one of the first status data lines 4114 and one of the memory modules 440 are illustrated); accordingly, the first status data line 4114 may transmit some status signals indicating the status of the hard disk 300 or the hard disk controller 310, generated on the corresponding hard disk controller 310, for example: the status signals of the hard disk 300, such as the temperature or capacity of the hard disk, and whether the hard disk is in operation, are transmitted from the hard disk controller 310 to the memory module 440. The memory module 440 stores the parameters represented by the status signals, and provides the parameters to the interface board via the second status data line 4216 electrically coupled between the memory module 440 and the interface board connection port 4210 when the interface board requests the parameters, or after a certain time interval, so that the interface board can determine how to control the operation of the entire multi-hard-disk storage device, for example: the light control line 4214 electrically coupled between the interface control board connection port 4210 and the light group 430 controls the light emitting pattern of each light in the light group 430 to indicate which of the plurality of hard disks 300 are activated, or controls the on and off of each fan in the fan group (not shown) for heat dissipation through other control lines to match the number or position of the activated hard disks 300 for heat dissipation. The present invention provides a plurality of memory modules 440 can respectively correspond to a portion of the plurality of controller connection ports 4110.
Referring next to fig. 5, a block diagram of an interface control board according to an embodiment of the invention is shown. In the present embodiment, the interface control board 50 includes a central control chipset 510, a plurality of network connection ports 500 and 520-532, a plurality of data lines 550-562 and a control line 540. Each of the network connection ports 500, 520-532 is electrically coupled to a corresponding network connection hole (e.g., RJ-45 connection hole) for data interaction with the outside. In addition, although the data lines 550-562 and the control line 540 are shown as a single line in the embodiment, one or more of the data lines 550-562 and the control line 540 may be a bus, and is not limited to a single trace.
In this embodiment, the data received from the network connection port 500 is transmitted to the central control chipset 510, and the central control chipset 510 determines which hard disk needs to be activated according to the data received from the network connection port 500 and generates the correct control signals (e.g. the aforementioned control signals C1-C4) to the control lines 540, so as to transmit the control signals to the control lines on the backplane to control the hard disk to be opened or closed. To mate with the backplane shown in fig. 4A or 4B, the present embodiment provides a gold finger-like protrusion 55 on the interface control board 50. The protrusion 55 can be inserted into the interface board connection port 4210 shown in fig. 4A or 4B, so that the data lines 520-532 are electrically coupled to the data lines 4112 on the backplane in a one-to-one manner, and the control line 540 is electrically coupled to the control line 4212, the light control line 4214, the second status data line 4216, a fan set, a power supply (not shown), and the like. Thus, the central control chipset 510 can separately control the on/off of each hard disk in the manner described above; after the hard disk is turned on, the data fetched from the hard disk and the data to be entered into the hard disk can be directly transmitted in two directions through the network connection ports 520-532, the data lines 550-562 and the data lines (e.g., the data line 4112 in fig. 4A) correspondingly connected to the backplane.
Through foretell hard disk of combination, hard disk controller, bottom plate and interface control panel, just can obtain utilizing the utility model discloses many hard disk storage device that the technique formed. Please refer to fig. 6, which illustrates a multi-hard disk storage device 60 according to an embodiment of the present invention. In the present embodiment, in addition to the hard disk controller, the backplane and the interface control board in the above embodiment, the multi-hard disk storage device 60 further includes a metal cover 320 on the hard disk controller 310. The hard disk 300, the hard disk controller 310 and the metal cover 320 may together form a hard disk module. One side of the hard disk controller 310 is locked on the corresponding hard disk 300, and the other side or the whole of the hard disk controller 310 is covered by the metal cover 320. The metal cover 320 covers part or all of the hard disk controller 310 and is disposed between the hard disk controller 310 and other adjacent hard disk modules. Thereby, the metal cover 320 can shield the hard disk controller 310 from the electronic signals (e.g., electromagnetic interference) of the hard disk or hard disk controller in other hard disk modules, so that the hard disk modules can be arranged more closely together without affecting each other. Another advantage of forming the hard disk 300, the hard disk controller 310 and the metal cover 320 into a hard disk module is that when one hard disk or the hard disk controller in the multiple hard disk storage device 60 fails, only the hard disk module needs to be replaced, and the entire bottom board, the interface control board or all other hard disks do not need to be moved. In another embodiment of the present invention, the hard disk module may not include the metal cover 320, which still has the advantage of easy maintenance and replacement. In addition, a fan set is disposed in the multi-hardware storage device 60, and the fan set includes eight fans 610-624, and these fans 610-624 are electrically coupled to the central control chipset in the manner described in the previous embodiment, so as to be controlled by the central control chipset to determine the on or off status thereof. In another embodiment of the present invention, the multiple hard disk storage device 60 may include a plurality of bottom boards 400, a plurality of corresponding interface control boards 50 and a plurality of corresponding hard disk modules, wherein each bottom board 400 and each corresponding interface control board 50 operate as set forth in the previous embodiment.
In order to effectively increase the number of hard disks which can be installed in the same multi-hard disk storage device, a plurality of I disks can be further arranged and used on the bottom plate2A GPIO (General Purpose Input/Output) extension chip of a C (Inter-Integrated Circuit) interface. At this time, each GPIO expansion chip may be electrically coupled to the interface controllerThe central control chip group of the manufacture board and a part of the hard disk controller. At this time, when the central control chip set sends out the control signal to the part of the hard disk controller, the control signal is firstly transmitted to the GPIO expansion chip, then the GPIO expansion chip selects the correct hard disk controller, and transmits the control signal to the selected hard disk controller.
According to the above, since the on and off of each hard disk can be independently controlled, when a certain hard disk is not needed, the corresponding hard disk controller or switch can be turned off to stop the rotation of the hard disk, thereby achieving the effect of saving power. In addition, when a plurality of hard disks need to be started simultaneously, only one part of the hard disks can be started at a time, and then other hard disks are started after a period of time. For example, when 15 hard disks need to be started, 5 hard disks may be started first, and another 5 hard disks may be started after 3 seconds, and then the last 5 hard disks may be started after 3 seconds. Thus, the peak value of the instantaneous current can be effectively reduced.
According to the above, the utility model provides a many hard disks storage device can be with the switch of a plurality of hard disks separately control, consequently can make these hard disks not concentrate on same time point and open, and then avoided the production of too big electric current in the twinkling of an eye. Through the design, the overall reliability of the multi-hard-disk storage device can be effectively improved, and the power consumption can be reduced at an opportunity. In addition, modularizing the hard disk with the hard disk controller may also facilitate repair and replacement.
