Embodiment
Below in conjunction with specific embodiment, the present invention is described in detail.
Be illustrated in figure 1 a kind of composition structural representation supporting the disk array of logic destruction and physical destroying that the present invention proposes, this disk array comprises hard disk groups 4, hard disk backboard 3, destroys control module 2, memory controller 1, power supply 5, result display 8 and logic destruction button 6 and physical destroying button 7.
Hard disk in the present embodiment in hard disk groups adopts the hard disk supporting self-destruction, as source section huge rock dragon 2.5 cun of solid state hard disc RCV-V-T251T;
Hard disk backboard can be the storage server backboard of the standard of any compatible SAS and SATA hard disc, as AICBKP-SA2E-12H35G-28.If hard disk backboard supports the self-destroying function of hard disk, directly connect the corresponding interface, if do not supported, also can by utilizing the object reaching and transmit self-destruction control signal and reception feedback result to hard disk to other no interface.Namely this example not support that the AICBKP-SA2E-12H35G-28 of hard disk self-destroying function is described, this backboard has power interface 10, connects 5V and 12V power supply, to power uses, also have hard-disk interface 9, can connect also Fixed disk to hard disk backboard and hard disk.Hard-disk interface 9 is made up of data-signal and power supply signal.Each data have 7, are used for transmitting data, and power supply signal has 15, and wherein the 1st, 2,3,11 free time, 4,5,6,10,12 ground connection, 7,8,9 is 5V power supply, 13,14,15 connect 12V power supply.The current signal of hard disk backboard depends on power and load.Power 500W, enough provides the energy of physical destroying.During normal work, the use electric current of each hard-disk interface 5V operating voltage is about 600mA, and when performing physical destroying, electric current can reach more than 7A.The present embodiment utilizes idle 1,2, and 3 are done self-destruction and control, and destroy signal be connected the 1st with the logic of destroying in control module, and the 2nd is connected with the destruction indicator signal of destroying in control module, and the 3rd is connected with the physical destroying signal destroyed in control module.When equipment uses as conventional disk array, by the data-interface transmission data of hard disk backboard, hard disk data reading or write are connected with backboard by memory controller controls, when destroying function and triggering, by the destruction interface of definition, signal transmission will be destroyed to hard disk, and regain destruction indicator signal.
Power supply is server A TX power supply, according to loading condition, memory controller and destruction control module are about power consumption 100W, this routine disk array is 9 dish positions, and under normal operating conditions, every block disk read-write consumed power is 3W, during physical destroying, power is maximum, every block hard disk consumes 5V × 7A=35W, and 9 pieces of hard disks then need 35W × 9=315W, and system maximum consumption power is about 415W.According to calculating, this example selects 500W power supply to satisfy the demand, and other designs can select the power supply of different capacity according to actual conditions.
Destroy control module to be used for according to destroying the logic that provides of button or physical destroying signal sends destroy command to hard disk backboard, and the destruction result receiving its feedback is shown by result display.Described destruction control module destroys signal when receiving logic, then sending logic and destroy command to hard disk backboard, then sending physical destroying instruction to hard disk backboard when receiving physical destroying signal.When performing destruction, collect the destroy state signal of hard disk, make and destroy result instruction.
In the present embodiment, logic is destroyed and the concrete key mode of physical destroying does not limit, any-mode can be defined in theory, this example is simple and clear description, and the disaster brought for avoiding user misoperation, definition is long destroys button more than 6 two seconds for logic destruction instruction by logic, and long physical destroying button more than 7 three seconds of pressing is for physical destroying instruction; The specific implementation of result display can be any-mode, destroy successfully or failed result to user feedback as long as can meet, pilot lamp is used to carry out result instruction in the present embodiment, pilot lamp display green expression successfully carries out logical OR physical destroying, and the red expression of display fails and destroys.
The control flow destroying control module is as follows:
When not starting destruction program, disk array is in normal operation state, and power supply 5 powers to each board, and by the control of memory controller 1, hard disk groups 4 carries out read-write operation.As shown in Figure 2, destroy button 6 when logic to press, destruction control module 2 receives logic and destroys pending signal, start timer internal, timing terminates for two seconds, logic is destroyed button 6 and is remained down state, then judge that receiving correct logic destroys instruction, logic will be sent to hard disk backboard 3 and destroy signal, logic is destroyed signal transmission to the hard disk 4 patched thereon by hard disk backboard 3, hard disks 4 all on hard disk backboard 3 all can receive logic and destroy signal, carry out logic destruction simultaneously, originally the data deposited in hard disk 4 are capped, reach the object that mathematical logic is destroyed.When physical destroying button 7 is pressed, destroy control module 2 and receive the pending signal of physical destroying, start timer internal, timing terminates for three seconds, physical destroying button 7 remains down state, then think and receive correct physical destroying instruction, physical destroying signal will be sent to hard disk backboard 3, hard disk backboard 3 by physical destroying signal transmission to grafting hard disk 4 thereon, physical destroying signal received by hard disk 4 on hard disk backboard 3, hard disk 4 is under internal logic controls, hard disk 4 internal load reduces, electric current sharply increases, be not less than the High-current output of 7A (5V) to hard-disk interface 9 place on hard disk backboard 3, by the circuit burnout of hard disk 4, damage storage medium, destroy hard disk and data.When hard disk 4 performs destruction action, every block hard disk 4 all can send destroys indicator signal to destruction control module 2, destroy logic destruction and physical destroying situation that control module 2 collects every block hard disk 4, judge that all hard disks 4 are all destroyed successfully, then send destruction successfully to indicate, green indicating lamp is bright, otherwise destroys unsuccessfully, and red led is bright.
By the enforcement of the invention described above, what user can be easy carries out logic destruction or physical destroying at short notice fast to the hard disc data on disk array, to tackle emergency.
The above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention; some improvement can also be made; or carry out equivalent replacement to wherein portion of techniques feature, these improve and replace and also should be considered as protection scope of the present invention.
