corresponding to each hard disk unit 2 electrically connected to the servo system, compares the detected information to be identified corresponding to the hard disk units 2 with the plurality of default identification information in the white list, and determines whether the detected information to be identified corresponds to one default identification information of the white list, If the

white list, wherein the plurality of default identification information recorded in the white list includes a plurality of manufacturer identifiers, respectively, and the management module 4 specifically includes a relay unit 41 electrically connected to each switch unit 3, a bus channel switch 42 electrically connected between the relay unit 41 and the baseboard management controller 5, a memory module 43 electrically connected to the relay unit 41, the memory module 43 stores the white list and is used for recording related information about the plurality of hard disk units 2, In more detail, the memory module 43 has a first memory unit 431 for storing the whitelist and a second memory unit 432 for recording related information about the plurality of hard disk units 2, and it should be noted that, in this embodiment, the management module 4 is a programmable logic device (PLD: programmable Logic Device), such as a field programmable logic gate array (FPGA: field Programmable GATE ARRAY), a complex programmable logic device (CPLD: complex Programmable Logic Device), The trunk unit 41 and the Bus channel switch 42 are circuits synthesized by the management module 4 in cooperation with hardware description language such as Verilog, and the Bus channel switch 42 is electrically connected with the baseboard management controller 5 through a system management Bus (SMBus: SYSTEM MANAGEMENT Bus), in addition, the Bus channel switch 42 and the trunk unit 41 are electrically connected through a plurality of groups of connecting lines with the same number as the hard disk units 2, the first memory unit 431 is a non-volatile memory, the second memory unit 432 is a volatile memory, wherein the first memory unit 431 is used for recording standard answers of the whitelist, i.e. the default identification information and the default password, REGISTER MAP of the second memory 432 is used for recording the manufacturer identifier and/or corresponding address of the hard disk unit 2 conforming to the whitelist, which is monitored and compared with the inserted connection servo system in the initialization process of the management module 4, i.e. recording data, when the management module 4 is initialized, each switch unit 3 for connecting to the hard disk unit 2 is scanned one by one to skip the switch units 3 not inserted with the connection hard disk, and then confirm which of the hard disk units 2 inserted with the switch units 3 conforms to the whitelist, That is, the information to be identified of the hard disk unit 2 matches one of the default identification information of the white list, and then the information to be identified or the default identification information of the hard disk unit 2 matching the white list is recorded REGISTER MAP as recording data, in detail, the management module 4 obtains the corresponding address according to the manufacturer identifier of the hard disk unit 2 matching the white list and records REGISTER MAP as recording data, and the corresponding address of the hard disk unit is the address of the hard disk unit 2 or the address of the slot in which the hard disk unit 2 is inserted and connected, wherein the management module 4 is composed of the memory module 43, After the hard disk unit 2 or other storage components in the servo system obtain the address corresponding to the hard disk unit 2, the management module 4 only needs to monitor, manage and compare the corresponding hard disk unit 2 with the recorded data, when the hard disk controller 5 needs to communicate with the hard disk unit 2 corresponding to any one of the specified addresses later, the management module 4 will confirm that the specified address is the inserted hard disk unit 2 from the second memory 432 according to the address specified by the baseboard management controller 5 and that the information to be identified of the currently connected hard disk unit 2 accords with the specified hard disk unit 2 of the recorded data, if yes, then use the default password in the first memory 431 to confirm whether the hard disk password accords with the default password with the hard disk unit 2 specified by the baseboard management controller 5, If yes, the management module 4 connects the specified hard disk unit 2 with the baseboard management controller 5, so that the baseboard management controller 5 can read the specified hard disk unit 2.
The baseboard management controller 5 is electrically connected to the management module 4, and the baseboard management controller 5 issues an access command to the management module 4, where the access command indicates an address of one of the hard disks, and it should be further described that, the baseboard management controller 5 transmits the access command through a control Bus different from the system management Bus, or communicates with the management module 4 through command transmission, where the control Bus may be, for example, an integrated circuit Bus (I2C: inter-INTEGRATED CIRCUIT), a serial general Purpose Input/Output (SGPIO: SERIAL GENERAL Input/Output) Bus, an LPC Bus (LPC Bus: low Pin Count Bus), or an intelligent platform management interface Bus (IPMI Bus: INTELLIGENT PLATFORM MANAGEMENT INTERFACE Bus), where the management module 4 controls the Bus channel switch 42 to connect the baseboard management controller 5 to one of the channels of the plurality of channels respectively connected to the respective units 2 through the relay unit 41 according to an access command and a check result of record data/default password received from the control Bus.
The management module 4 then determines whether the address indicated by the access command corresponds to the address to be identified of the hard disk unit 22 according to the address indicated by the access command and REGISTER MAP stored in the second memory unit 432, more specifically, when the address included in the access command corresponds to one of the sets of record data in REGISTER MAP, that is, the address included in the access command corresponds to the address in one of the sets of record data in REGISTER MAP, then detects whether the address corresponds to the address to be identified of the hard disk unit 2 still corresponds to the set of record data in REGISTER MAP, if so, determines that the address indicated by the access command corresponds to the record data, that is, corresponds to REGISTER MAP, and further corresponds to the white list, and then reads the hard disk password of the corresponding hard disk unit 2 according to the access command, and comparing the hard disk password with the default password corresponding to the information to be identified indicated by the access command in REGISTER MAP, and controlling the corresponding hard disk unit 2 to operate in the disabled state when the hard disk password read by the specified hard disk is compared with the corresponding default password stored in the first memory unit 431, wherein when the address indicated by the access command is not matched with the address in all the record data in REGISTER MAP, it is determined that the address indicated by the access command is not matched with any record data in REGISTER MAP, the address indicating the access command is determined to be the address of the non-inserted hard disk in the process of initializing to perform scan confirmation by the management module 4, or the inserted hard disk unit 2 is switched to operate in the disabled state because the address indicated by the access command is not matched with the white list of the first memory unit 431, that is, the management module 4 does not need to manage the address, so when the management module 4 determines that the address of the received access command does not match the recorded data in the second memory unit 432, the comparison of the to-be-identified information and the hard disk password of the hard disk unit 2 corresponding to the address is not continued, and the execution of the access command is not continued, thereby preventing the hard disk unit 2 corresponding to any set of recorded data recorded by the second memory unit 432 from being replaced with other illegal hard disk units after the initialization process of the management module compares the to-be-identified information of the inserted hard disk with the default identification information in the white list one by one and records the to-be-identified information of the hard disk unit 2 corresponding to the default identification information in the white list, and after the second memory unit 432 is located in the server system, any hard disk controller capable of accessing the hard disk, for example, the hard disk controller 5 corresponding to any set of recorded data of the second memory unit 432 is replaced with other illegal hard disk units, so that the hard disk controller 5 is replaced with other illegal hard disk units, and the host controller 5 is damaged by the virus, and the host controller is replaced with other illegal hard disk controllers.
More specifically, when the management module 4 performs the initialization process, the relay unit 41 of the management module 4 detects the connection states of the plurality of switch units 3 connected with the relay unit and the hard disk one by one to further read the plurality of information to be identified of the plurality of hard disk units 2 connected with the hard disk unit 2 in the plurality of switch units 3 to find and record the information to be identified or default identification information corresponding to the hard disk unit 2 corresponding to the white list stored in the first memory unit 431 in the second memory unit 432 as record data, and then selectively reads the hard disk password stored in the hard disk corresponding to the access command according to the access command from the baseboard management controller 5 and the record data recorded in the second memory unit 432, and then compares the hard disk password with the default password.
When the relay unit 41 compares the read information to be identified with each default identification information stored in the white list, the relay unit 41 controls the corresponding hard disk unit 2 to switch to the disabled state, more specifically, the relay unit 41 controls the corresponding switch unit 3 to switch to be non-conductive, so that the hard disk unit 2 does not receive the driving voltage and is in the disabled state where the data cannot be read, in addition, in the embodiment, the bus channel control inside the relay unit 41 itself may also switch to be non-conductive with the hard disk units 2 which do not conform to the white list or record the data, that is, the switch units 3 respectively connect the bus channels inside the relay unit 41 with the corresponding hard disk units 22, or the switch units 3 are respectively arranged inside the relay unit 41 and electrically connect the hard disk units 2, and the switch units 3 are non-conductive by the relay unit 41, thereby the bus channel switch 42 is non-conductive with the hard disk units 2 which do not conform to the white list. The bus channel switch 42 is electrically connected to the hard disk unit 2 by a plurality of groups of bus channels having the same number as the plurality of switch units 3 in the relay unit 41 itself.
When the trunk unit 41 compares the hard disk passwords stored in the hard disk units 2 corresponding to the access command with the default passwords, the management module 4 determines to switch which hard disk unit 2 is connected to at least one of the plurality of switch units 3 and the plurality of hard disk units 2 via the plurality of bus channels, the bus channel switch 42 selectively connects the hard disk controller 5 to at least one of the plurality of communication ports 421, each of the plurality of communication ports 421 corresponds to a communication port number corresponding to a plurality of bus channels, the plurality of switch units 3 and the plurality of hard disk units 2, respectively, for the baseboard management controller 5 to read the hard disk units 2 corresponding to the access command, the plurality of communication ports 421 respectively, and the plurality of switch units 2 are electrically connected to the plurality of bus channels through the plurality of connection lines respectively for the trunk unit 41, the bus channel switch 42 is controlled to selectively connect the hard disk controller 5 to at least one of the plurality of switch units 2 via the plurality of bus channels, each of the plurality of communication ports 421 corresponds to the plurality of communication ports 421 corresponding to the plurality of switch units 2, the bus channel switch units 2 is controlled according to the connection state of the trunk unit 41, the bus channel switch unit 41 is controlled to selectively connect the corresponding to the one of the plurality of switch units 2 to the corresponding to the bus channel switch units 41, and the corresponding to the access command is controlled by the bus channel switch unit 41, that is, the connection mode inside the bus channel switcher 42 is controlled to connect the baseboard management controller 5 to the bus channel corresponding to the hard disk unit 2 indicated by the access command in the relay unit 41, wherein the plurality of record data of the second memory unit 432 further includes default identification information or the communication port number corresponding to the information to be identified of the plurality of hard disk units 2 inserted and conforming to the whitelist, wherein the management module 4 obtains and records the corresponding communication port number to the corresponding record data according to the default identification information or the information to be identified of the plurality of hard disk units 2 inserted and conforming to the whitelist, when the relay unit 41 compares the corresponding hard disk passwords with the default passwords, the relay unit 41 triggers the management module to control the connection mode of the communication port corresponding to the hard disk unit 2 indicated by the access command and the baseboard management controller 421 to be in a non-transmittable state, in addition, when the relay unit 41 compares the corresponding hard disk passwords with the default passwords corresponding to the whitelist, the relay unit 41 can control the switch unit 3 to be not to be connected to the external hard disk unit 22, and the external controller 22 can not be connected to the external hard disk unit 22 to implement the control module 22.
The verification procedure of the present invention can be further summarized from the above embodiments as follows:
1. Only the address indicated by the access command and the record data are compared, if the address indicated by the access command does not exist in the record data, the hard disk unit 2 corresponding to the address indicated by the access command is not inserted into the corresponding hard disk slot, or the corresponding hard disk slot inserted into the corresponding hard disk slot but is not consistent with the white list content, so that even if the corresponding hard disk slot of the address indicated by the access command is connected with the hard disk unit 2, the hard disk unit 2 is switched to a disabled state when the management module 4 is initialized, and the bus channel switcher 42 and/or the relay unit 41 are controlled to be not connected with the hard disk slot corresponding to the address corresponding to the access command.
