In addition, seeing also Fig. 1, is to insert or remove process flow diagram for the disc driver of prior art.As shown in the figure, step S01 is the main frame of an operate as normal.As the insertion that will carry out disc driver on the IDE bus or when shifting out action, all programs that computing machine must carried out stop, as step S02; And with the main frame power-off, as step S03.After definite computer power supply is closed, just can on the IDE bus, carry out the insertion of disc driver or remove action, as step S04.Then carry out step S05, computer power supply is opened again, the back computing machine of electric power starting will carry out general boot program, and will detect the disc driver of new insertion this moment, as step S06; And all disc drivers are reset, shown in the step S07.After replacement finished, computing machine entered general normal operating conditions, and computer system can normally be used this moment, as step S08.
By said process as can be known, when carrying out the disc driver Plug Action, the action that shut down repeatedly and start shooting, and must stop all executory programs, extremely inconvenient in the use.
The utility model content
The purpose of this utility model is to be used as with the IDE hard disk medium of disk array, makes the manufacturing cost of disk array reduce rapidly.
Another purpose of the present utility model is to provide the mechanism of the system of ide interface disk array, and connects an equipment for protection of disc between IDE bus and IDE disk array, makes the medium of ide interface have the function of hot plug.
Technical solutions of the utility model are as follows:
A kind of disc array system that has protective device is characterized in that, includes:
One disk array controller comprises at least one IDE controller, and each IDE controller is connected with at least one IDE bus, and described disk array controller utilizes IDE controller and IDE bus and connection ID E hard disk; And
One equipment for protection of disc is installed between IDE bus and the IDE hard disk, comprises control circuit board, detection module;
Wherein, this control circuit board is provided with one first a power supply link block and a second source link block, and this first power supply link block is connected with the power end of this IDE hard disk, and this second source link block is connected with the power end of this electronic system;
Wherein, this detection module is arranged on this circuit board, and also comprise a delay circuit and a microprocessor, this delay circuit couples with this first power supply link block, this second source link block and this microprocessor respectively, and whether this processor is to control this delay circuit is come into force, with the power end of this electronic system of conducting and this hard disk.
Further; described circuit board also comprises the first signal link block and secondary signal link block; this protection module also comprises a working storage; this first signal link block is connected with the signal end of this hard disk; this secondary signal link block is connected with the signal end of this electronic system; this working storage couples with this first signal link block, this secondary signal link block and this microprocessor respectively; and whether this microprocessor is to control to make this working storage effective, with the signal end of this electronic system of conducting and this hard disk.
Further, this detection module includes a system timer.
The utility model has the advantages that: by between IDE bus and IDE disk, increasing by an equipment for protection of disc, avoided hard disk abnormality such as the entanglement of wrong road, short circuit under abnormality, to occur, the function of supporting hot plug is provided.Under situation cheaply, realized the security and the reliability of disc array system.
Description of drawings
Fig. 1 is the hard disk drive plug process flow diagram of prior art;
Fig. 2 is the overall construction drawing of disc array system of the present utility model;
Fig. 3 is the protective device structural representation of disc array system of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 2, be the structural drawing of the equipment for protection of disc of disc array system of the present utility model.Electronic system comprises main frame and adds disk array controller, adds protected location between IDE bus and IDE hard disk, to avoid making the IDE hard disk corruptions when the hot plug.
As shown in Figure 3, be protective device structural drawing of the present utility model, disk array controller and IDE hard disk respectively have a signal end and a power end, in order to transmit signal or power supply.Equipment for protection of disc has the first signal link block 106 and the first power supply link block 107, secondary signal link block 104 and second source link block 105; its the first signal link block 106 and the first power supply link block 107 be the signal end 108 and the power end 109 of connection ID E hard disk respectively, and its secondary signal link block 104 is connected signal end 102 and the power end 103 that electronic system is a disc array system respectively with second source link block 105.The working storage two ends connect the first signal link block 106 and secondary signal link block 104 respectively; Delay circuit unit 114 connects the power supply of the first power supply link block 107 and second source link block 105 respectively, microprocessor 112 provides and postpones validate signal to delay cell 114, this effect that postpones validate signal is the moment of avoiding the IDE hard disk the to insert phenomenon that is short-circuited, and behind a setting-up time, this is postponed validate signal become invalid; Microprocessor 112 also provides temporary validate signal to working storage, and the effect of this temporary validate signal is that the phenomenon of entanglement takes place the moment of avoiding the IDE hard disk to insert, and behind a setting-up time, this temporary validate signal is become invalid.For example, newly-increased IDE hard disk, equipment for protection of disc produces inhibit signal and temporary signal, and behind a setting-up time, with inhibit signal and temporary Signal Fail to protect newly-increased IDE hard disk.Equipment for protection of disc provides IDE hard disk protection function.
