Description

伺服器資料備援控制方法Server data backup control method

本發明是有關於一種控制方法，特別是指一種伺服器資料備援控制方法。The present invention relates to a control method, in particular to a server data backup control method.

在電腦或伺服器中，已常見利用集束磁碟系統 (如：Just a Bunch Of Disks, JBOD)進行系統資料儲存管理。一般來說，JBOD設備是通過內部的一硬碟擴展控制單元(expander)連接複數硬碟，同時對JBOD設備與該複數硬碟的資訊進行偵測，並產生對應的偵測資訊(例如溫度或啟閉狀態等)。當該JBOD設備連接一主機時，即可依據該主機發出的指令進行對應作動，例如將上述偵測資訊回傳至該主機，或是存取該複數硬碟的資料等，且硬碟擴展控制單元的控制器模組可接收伺服器的資料狀態訊息而可監控與儲存伺服器系統運作的狀態如：CPLD狀態資料訊息、Cable連線 狀態資料訊息、Sensor狀態資料訊息、LED狀態資料訊息等狀態資料訊息與接收所述硬碟的介面實體層(PHY)狀態資料訊息。在資料儲存技術中，常見利用可互相備援資料的主控制器與從屬控制器的雙控制器模組，主控制器除了會定期將自身所有資料狀態訊息同步(Sync)更新至從屬控制器進行備援，且主控制器也會定期向從屬控制器篩取訊息，並當主控制器向從屬控制器篩取完資料後會將所述資料與自身的資料整合後再傳給從屬控制器進行同步更新全部的資料狀態訊息，而可備份儲存與保護資料，有效避免單一控制器模組發生異常導致資料損毀的問題。In computers or servers, it is common to use cluster disk systems (such as: Just a Bunch Of Disks, JBOD) for system data storage management. Generally speaking, a JBOD device connects multiple hard disks through an internal hard disk expansion control unit (expander), and simultaneously detects the information of the JBOD device and the multiple hard disks, and generates corresponding detection information (such as temperature or open state, etc.). When the JBOD device is connected to a host, it can perform corresponding actions according to the instructions issued by the host, such as returning the above-mentioned detection information to the host, or accessing the data of the plurality of hard disks, etc., and the hard disk expansion control The controller module of the unit can receive the data status message of the server and can monitor and store the status of the server system operation, such as: CPLD status data message, Cable connection status data message, Sensor status data message, LED status data message, etc. A data message and an interface physical layer (PHY) status data message for receiving the hard disk. In data storage technology, it is common to use a dual-controller module with a master controller and a slave controller that can back up data for each other. The master controller will periodically update all its data status messages to the slave controller for synchronization. Backup, and the master controller will periodically filter information from the slave controllers, and when the master controller finishes filtering the data from the slave controllers, it will integrate the data with its own data and then send it to the slave controllers for further processing Synchronously update all data status information, and can back up, store and protect data, effectively avoiding the problem of data damage caused by abnormality of a single controller module.

然而，主控制器每次將自身所有資料狀態訊息同步(Sync)更新至從屬控制器的資料量是非常大的，且當主控制器中只有少許資料需要同步更新至從屬控制器時，主控制器還是會將全部的所有資料狀態訊息同步(Sync)更新至從屬控制器，非常花費時間且效率低。再者，主控制器每次向從屬控制器篩取訊息資料量也是非常龐大，而且就算從屬控制器的所述資料狀態訊息沒有變動，主控制器還是會定期向從屬控制器篩取訊息，實在沒有效率。並當主控制器向從屬控制器篩取完資料後會將所述資料與自身的資料整合後再傳給從屬控制器進行同步更新全部的所有資料狀態訊息，而使主控制器與從屬控制器需定期進行多次的溝通且溝通訊息量龐大，不僅非常浪費時間且主控制器與從屬控制器常會進行多次無意義的篩取與備份沒有被更動的資料狀態訊息，造成效率不佳，需從業人員進一步探討與改善。However, the amount of data that the master controller updates all its own data status messages to the slave controllers each time is very large, and when only a small amount of data in the master controller needs to be synchronously updated to the slave controllers, the master controller However, the controller will still update all the data status messages to the slave controller synchronously (Sync), which is very time-consuming and inefficient. Furthermore, the amount of information that the master controller screens from the slave controllers each time is also very large, and even if the data status information of the slave controllers does not change, the master controller still regularly screens messages from the slave controllers. not efficient. And when the master controller has screened the data from the slave controller, it will integrate the data with its own data and then send it to the slave controller to update all the data status messages synchronously, so that the master controller and the slave controller It is necessary to communicate multiple times on a regular basis and the amount of communication messages is huge. Not only is it a waste of time, but the master controller and the slave controller often perform multiple meaningless screening and backup of data status messages that have not been changed, resulting in poor efficiency. Practitioners further explore and improve.

因此，本發明之目的，即在提供一種降低讀取資料量且效率佳的伺服器資料備援控制方法。Therefore, the purpose of the present invention is to provide a server data backup control method that reduces the amount of read data and has high efficiency.

且於該監控步驟C中，該第一管理單元21監控所述資訊群組中的所述主控系統狀態資料與所述硬碟狀態資料，當該第一管理單元21監控到所述資訊群組中的任一主控系統狀態資料或任一硬碟狀態資料被更新時，該第一管理單元21將被更新的主控系統狀態資料或被更新的硬碟狀態資料所對應的該資訊群組的狀態位元值更改為一第二位元值，該從屬硬碟擴充卡裝置4的第二管理單元41監控所述資訊群組中的所述從屬系統狀態資料與所述硬碟狀態資料，當該第二管理單元41監控到所述資訊群組中的任一從屬系統狀態資料或任一硬碟狀態資料被更新時，該第二管理單元41將被更新的從屬系統狀態資料或被更新的硬碟狀態資料所對應的該資訊群組的狀態位元值更改為該第二位元值。也就是說，該主硬碟擴充卡裝置2的第一管理單元21會監控自身的所述資訊群組中的所述主控系統狀態資料與所述硬碟狀態資料且將有更新的所述主控系統狀態資料或有更新的所述硬碟狀態資料對應的該資訊群組的狀態位元值更改設定為該第二位元值。換句話說，只要該資訊群組的狀態位元值為該第二位元值，就代表該資訊群組中的至少一資料是有更改變動。以及該從屬硬碟擴充卡裝置4的第二管理單元41也會監控自身所述資訊群組中的所述從屬系統狀態資料與所述硬碟狀態資料且將有更新的從屬系統狀態資料或有更新的所述硬碟狀態資料所對應的該資訊群組的狀態位元值更改為該第二位元值。簡單來說，只要該資訊群組的狀態位元值為該第二位元值，就代表該資訊群組中的至少一資料是有更改變動。And in the monitoring step C, the first management unit 21 monitors the main control system status data and the hard disk status data in the information group, when the first management unit 21 monitors the information group When any master control system status data or any hard disk status data in the group is updated, the first management unit 21 will update the information group corresponding to the master control system status data or the updated hard disk status data The status bit value of the group is changed to a second bit value, and the second management unit 41 of the slave hard disk expansion card device 4 monitors the slave system status data and the hard disk status data in the information group When the second management unit 41 monitors that any slave system status data or any hard disk status data in the information group is updated, the second management unit 41 will update the slave system status data or be updated The status bit value of the information group corresponding to the updated hard disk status data is changed to the second bit value. That is to say, the first management unit 21 of the main hard disk expansion card device 2 will monitor the master control system state data and the hard disk state data in the information group of itself and will have updated The status bit value of the information group corresponding to the status data of the master control system or the updated hard disk status data is set to the second bit value. In other words, as long as the status bit value of the information group is the second bit value, it means that at least one data in the information group has been changed. And the second management unit 41 of the slave hard disk expansion card device 4 will also monitor the slave system status data and the hard disk status data in the information group of itself, and will have updated slave system status data or have The status bit value of the information group corresponding to the updated hard disk status data is changed to the second bit value. In simple terms, as long as the status bit value of the information group is the second bit value, it means that at least one data in the information group has been changed.

接著，於該檢查步驟D中，包括一主檢查步驟D1，及一從屬檢查步驟D2。Then, in the checking step D, a main checking step D1 and a subordinate checking step D2 are included.

於該主檢查步驟D1中，該第一管理單元21執行該管理模組的一第一檢查指令且檢查該主硬碟擴充卡裝置2的每一資訊群組的狀態位元值，並判斷是否檢查到該主硬碟擴充卡裝置2的任一資訊群組的狀態位元值為該第二位元值，若判斷為是，則該第一管理單元21執行一同步更新指令。簡單來說，就是該第一管理單元21會檢查該主硬碟擴充卡裝置2的每一資訊群組的狀態位元值而用來判斷該主硬碟擴充卡裝置2的每一資訊群組是否有更新變動，若判斷為是，則該第一管理單元21執行一同步更新指令。進一步來說，就是該主硬碟擴充卡裝置2的第一管理單元21執行該第一檢查指令且只需檢查該主硬碟擴充卡裝置2的每一資訊群組的狀態位元值就可得知該主硬碟擴充卡裝置2的每一資訊群組中是否有更新變動的，不需要逐一檢查該主硬碟擴充卡裝置2中龐大的所述主控系統狀態資料與所述硬碟狀態資料，大幅降低檢查時所需讀取資料量。例如，於本實施例中，於該管理資料步驟B中，該主硬碟擴充卡裝置2的第一管理單元21將所述主控系統狀態資料與所述硬碟狀態資料分出的所述資訊群組分別為該第一資訊群組、該第二資訊群組，及該第三資訊群組共三組資訊群組，且於該主檢查步驟D1中，該第一管理單元21執行該第一檢查指令時，只需檢查該主硬碟擴充卡裝置2中的所述三組資訊群組的狀態位元值 (3bytes)即可，而不需要逐一檢查龐大數量位元的所述主控系統狀態資料與所述硬碟狀態資料。另外，相對來說，若於該主檢查步驟D1中，該第一管理單元21未檢查到該主硬碟擴充卡裝置2的任一資訊群組的狀態位元值為該第二位元值時，代表該第一管理單元21檢查到該主硬碟擴充卡裝置2的每一資訊群組的狀態位元值皆為該第一位元值，也就是此次該主硬碟擴充卡裝置2中的每一資訊群組的所述資料都沒有更新與變動。In the main checking step D1, the first management unit 21 executes a first checking command of the management module and checks the status bit value of each information group of the main hard disk expansion card device 2, and judges whether It is checked that the status bit value of any information group of the main hard disk expansion card device 2 is the second bit value, if it is determined to be yes, then the first management unit 21 executes a synchronous update command. To put it simply, the first management unit 21 will check the status bit value of each information group of the main hard disk expansion card device 2 to determine the value of each information group of the main hard disk expansion card device 2 Whether there is an update change, if it is determined to be yes, then the first management unit 21 executes a synchronous update command. Further speaking, the first management unit 21 of the main hard disk expansion card device 2 executes the first checking command and only needs to check the status bit value of each information group of the main hard disk expansion card device 2 Knowing whether there is an update change in each information group of the main hard disk expansion card device 2, it is not necessary to check the huge master control system state data and the hard disk in the main hard disk expansion card device 2 one by one. Status data, greatly reducing the amount of read data required for inspection. For example, in this embodiment, in the data management step B, the first management unit 21 of the main hard disk expansion card device 2 separates the main control system status data from the hard disk status data. The information groups are respectively the first information group, the second information group, and the third information group, a total of three information groups, and in the main checking step D1, the first management unit 21 executes the During the first check command, it is only necessary to check the state bit values (3 bytes) of the three groups of information groups in the main hard disk expansion card device 2, instead of checking the main data of a huge number of bits one by one. control system state data and the hard disk state data. In addition, relatively speaking, if in the main checking step D1, the first management unit 21 does not check that the status bit value of any information group of the main hard disk expansion card device 2 is the second bit value , it means that the first management unit 21 checks that the status bit value of each information group of the main hard disk expansion card device 2 is the first bit value, that is, the main hard disk expansion card device this time The information in each information group in 2 has not been updated or changed.

於從屬檢查步驟D2中，該主硬碟擴充卡裝置2的第一管理單元21執行該管理模組的一第二檢查指令且經該第一通信模組23與該第二通信模組43通訊連結而檢查該從屬硬碟擴充卡裝置4的每一資訊群組的狀態位元值，並判斷是否檢查到該從屬硬碟擴充卡裝置4的任一資訊群組的狀態位元值為該第二位元值，若判斷為是，該第一管理單元21發送一取得訊息至該第二管理單元41，且該第二管理單元41接收到該取得訊息後，並將每一狀態位元值為該第二位元值對應的資訊群組中的所有資料經該第二通信模組43傳至該第一通信模組23，且當該第二管理單元41將每一狀態位元值為該第二位元值對應的資訊群組中的所有資料經該第二通信模組43傳至該第一通信模組23後，該第二管理單元41將該第二位元值改回該第一位元值，而該第一管理單元21將該第一通信模組23所接收到所述資料更新至對應的資訊群組後回到該監控步驟C；若判斷為否，則該第一管理單元21執行該同步更新指令。也就是說，該第一管理單元21也會檢查該從屬硬碟擴充卡裝置4的每一資訊群組的狀態位元值而判斷該從屬硬碟擴充卡裝置4的每一資訊群組是否有需要進行篩取，若判斷為是，該第一管理單元21發送該取得訊息且該第二管理單元41接收到該取得訊息後，而將每一狀態位元值為該第二位元值對應的資訊群組中的所有資料傳至該第一管理單元21且當該第二管理單元41將每一狀態位元值為該第二位元值對應的資訊群組中的所有資料經該第二通信模組43傳至該第一通信模組23後，代表已將該主硬碟擴充卡裝置2所要篩取的資訊群組的所有資料傳完，所以該第二管理單元41會將該第二位元值改回該第一位元值，並該第一管理單元21將所接收到所述資料更新至對應的資訊群組後回到該監控步驟C。進一步來說，就是該主硬碟擴充卡裝置2的第一管理單元21執行該第二檢查指令時，只需檢查該從屬硬碟擴充卡裝置4的每一資訊群組的狀態位元值就可得知該從屬硬碟擴充卡裝置4的每一資訊群組是否有需要進行篩取，不需要逐一檢查該從屬硬碟擴充卡裝置4中龐大的所述從屬系統狀態資料與所述硬碟狀態資料，大幅降低檢查時所需讀取資料量。例如，於本實施例中，在該管理資料步驟B中，該從屬硬碟擴充卡裝置4的第二管理單元41將其所述從屬系統狀態資料與所述硬碟狀態資料分出與該主硬碟擴充卡裝置2的所述資訊群組相同內容的該第一資訊群組、該第二資訊群組，及該第三資訊群組共三組資訊群組，所以於該從屬檢查步驟D2中，當該第一管理單元21執行該第二檢查指令只需檢查該從屬硬碟擴充卡裝置4中的所述三組資訊群組的狀態位元值 (3bytes)即可，而不需要從該從屬硬碟擴充卡裝置4中逐一檢查龐大數量位元的所述從屬系統狀態資料與所述硬碟狀態資料。而於從屬檢查步驟D2中的檢查判斷結果為是時，代表該主硬碟擴充卡裝置2的第一管理單元21執行該第二檢查指令且檢查到該從屬硬碟擴充卡裝置4的任一資訊群組的狀態位元值為該第二位元值，則該第一管理單元21發送一取得訊息至該第二管理單元41，且該第二管理單元41接收到該取得訊息後，並將每一狀態位元值為該第二位元值對應的資訊群組中的所有資料經該第二通信模組43傳至該第一通信模組23，並該第一管理單元21將該第一通信模組23所接收到所述資料更新至對應的資訊群組。也就是說，於該從屬檢查步驟D2中，該主硬碟擴充卡裝置2的第一管理單元21檢查到該從屬硬碟擴充卡裝置4中有狀態位元值為該第二位元值，而得知該從屬硬碟擴充卡裝置4中有需要進行篩取的資訊群組，而該第一管理單元21發送該取得訊息至該第二管理單元41，且該第二管理單元41接收到該取得訊息後將每一狀態位元值為該第二位元值對應的資訊群組中的所有資料回傳給該主硬碟擴充卡裝置2，而該第一管理單元21透過該第一通信模組23所接收到所述資料更新至對應的資訊群組。簡單來說，就是該主硬碟擴充卡裝置2只會篩取該從屬硬碟擴充卡裝置4中為該第二位元值對應的資訊群組中的所有資料。另外，相對說，若於該從屬檢查步驟D2中，該第一管理單元21未檢查到該從屬硬碟擴充卡裝置4的任一資訊群組的狀態位元值為該第二位元值時，代表該第一管理單元21檢查到該從屬硬碟擴充卡裝置4的每一資訊群組的狀態位元值皆為該第一位元值，也就是此次該從屬硬碟擴充卡裝置4中的每一資訊群組的所述資料都沒有更新與變動，所以此次該主硬碟擴充卡裝置2無須向該從屬硬碟擴充卡裝置4篩取任一資料。In the slave inspection step D2, the first management unit 21 of the master hard disk expansion card device 2 executes a second inspection command of the management module and communicates with the second communication module 43 via the first communication module 23 Link and check the status bit value of each information group of the slave hard disk expansion card device 4, and judge whether the status bit value of any information group of the slave hard disk expansion card device 4 is checked. Two-bit value, if it is judged as yes, the first management unit 21 sends an acquisition message to the second management unit 41, and after the second management unit 41 receives the acquisition message, it sets each status bit value All data in the information group corresponding to the second bit value is transmitted to the first communication module 23 through the second communication module 43, and when the second management unit 41 sets each status bit value to After all data in the information group corresponding to the second bit value is transmitted to the first communication module 23 through the second communication module 43, the second management unit 41 changes the second bit value back to the The first bit value, and the first management unit 21 updates the data received by the first communication module 23 to the corresponding information group and then returns to the monitoring step C; A management unit 21 executes the synchronous update command. That is to say, the first management unit 21 also checks the status bit value of each information group of the slave hard disk expansion card device 4 to determine whether each information group of the slave hard disk expansion card device 4 has Screening is required, if the judgment is yes, the first management unit 21 sends the acquisition message and the second management unit 41 receives the acquisition message, and sets each status bit value corresponding to the second bit value All the data in the information group are transmitted to the first management unit 21 and when the second management unit 41 sets each status bit value to the second bit value, all the data in the information group corresponding to the second After the second communication module 43 transmits to the first communication module 23, it means that all the data of the information group to be screened by the main hard disk expansion card device 2 has been transmitted, so the second management unit 41 will The second bit value is changed back to the first bit value, and the first management unit 21 updates the received data to the corresponding information group and returns to the monitoring step C. Further speaking, when the first management unit 21 of the master hard disk expansion card device 2 executes the second check command, it only needs to check the status bit value of each information group of the slave hard disk expansion card device 4 It can be known whether each information group of the slave hard disk expansion card device 4 needs to be screened, and it is not necessary to check the huge slave system status data and the hard disk in the slave hard disk expansion card device 4 one by one. Status data, greatly reducing the amount of read data required for inspection. For example, in this embodiment, in the data management step B, the second management unit 41 of the slave hard disk expansion card device 4 separates the slave system status data and the hard disk status data from the master The first information group, the second information group, and the third information group of the same content as the information group of the hard disk expansion card device 2 are three groups of information groups, so in the subordinate checking step D2 Among them, when the first management unit 21 executes the second check instruction, it only needs to check the status bit values (3 bytes) of the three groups of information groups in the slave hard disk expansion card device 4, without The slave system status data and the hard disk status data of a huge number of bits are checked one by one in the slave hard disk expansion card device 4 . And when the check judgment result in the slave check step D2 is yes, the first management unit 21 representing the master hard disk expansion card device 2 executes the second check command and checks any one of the slave hard disk expansion card devices 4 . If the state bit value of the information group is the second bit value, then the first management unit 21 sends an acquisition message to the second management unit 41, and the second management unit 41 receives the acquisition message, and Send all the data in the information group corresponding to the second bit value for each status bit value to the first communication module 23 through the second communication module 43, and the first management unit 21 will The data received by the first communication module 23 is updated to the corresponding information group. That is to say, in the slave checking step D2, the first management unit 21 of the master hard disk expansion card device 2 checks that the state bit value in the slave hard disk expansion card device 4 is the second bit value, Knowing that there is an information group that needs to be screened in the slave hard disk expansion card device 4, and the first management unit 21 sends the acquisition message to the second management unit 41, and the second management unit 41 receives After obtaining the message, all the data in the information group corresponding to the second bit value of each status bit value is sent back to the main hard disk expansion card device 2, and the first management unit 21 passes the first The data received by the communication module 23 is updated to the corresponding information group. To put it simply, the master hard disk expansion card device 2 will only filter all the data in the information group corresponding to the second bit value in the slave hard disk expansion card device 4 . In addition, relatively speaking, if in the slave checking step D2, the first management unit 21 does not check that the status bit value of any information group of the slave hard disk expansion card device 4 is the second bit value , which means that the first management unit 21 checks that the status bit value of each information group of the slave hard disk expansion card device 4 is the first bit value, that is, the slave hard disk expansion card device 4 this time The data in each information group in the above information group has not been updated or changed, so the master hard disk expansion card device 2 does not need to filter any data from the slave hard disk expansion card device 4 this time.

要特別說明的是，於本實施例中，該第一管理單元21是在該主檢查步驟D1中的檢查判斷結果為是(Y)且在該從屬檢查步驟D2中的檢查判斷結果為否(N)的條件下，該第一管理單元21會執行該同步更新指令。換句話說，就是該第一管理單元21判斷檢查到該主硬碟擴充卡裝置2中的至一資訊群組的狀態位元值為該第二位元值且判斷沒有檢查到該從屬硬碟擴充卡裝置4中的任一資訊群組的狀態位元值為該第二位元值時，該第一管理單元21才會執行該同步更新指令且進行該同步更新步驟E，若是其他情況，例如：該第一管理單元21判斷在該主檢查步驟D1中沒有檢查到該第二位元值，代表此次該主硬碟擴充卡裝置2中的每一資訊群組的所述資料都沒有更新與變動，則不用進行後續更新備援資料至該從屬硬碟擴充卡裝置4的動作，並回到該監控步驟C。或是例如：若是在該從屬檢查步驟D2中檢查到該從屬硬碟擴充卡裝置4中的任一資訊群組的狀態位元值為該第二位元值，代表該從屬硬碟擴充卡裝置4中有至少一資訊群組的資料有更新變動，則該第一管理單元21發送該取得訊息取得該從屬硬碟擴充卡裝置4中為該第二位元值對應的資訊群組的資料後回到該監控步驟C，但不以此為限。另外一提，舉例來說，於本實施例中，該主硬碟擴充卡裝置2的第一管理單元21將I²C狀態資料訊息歸類於該第二資訊群組，而I²C狀態資料訊息具有該主硬碟擴充卡裝置2中I²C匯流排(圖未示)的使用狀態與該從屬硬碟擴充卡裝置4中I²C匯流排(圖未示)的使用狀態的資訊，而當該從屬硬碟擴充卡裝置4中I²C狀態資料訊息已有更新時，該第一管理單元21透過該第一通信模組23接收到該從屬硬碟擴充卡裝置4中已更新的I²C狀態資料訊息，且更新至自身對應的該第二資訊群組I²C狀態資料訊息，例如該主硬碟擴充卡裝置2中該第二資訊群組的I²C狀態資料訊息具有該主硬碟擴充卡裝置2中6條I²C匯流排的使用狀態與該從屬硬碟擴充卡裝置4中2條I²C匯流排的使用狀態的資訊，而當該第一管理單元21透過該第一通信模組23接收到該從屬硬碟擴充卡裝置4中已更新的I²C狀態資料訊息後，會將該主硬碟擴充卡裝置2中該第二資訊群組的I²C狀態資料訊息中對應該從屬硬碟擴充卡裝置4中2條I²C匯流排的使用狀態進行更新。此時，在該主硬碟擴充卡裝置2中，由於該第二資訊群組的I²C狀態資料訊息已有更新，所以於下次執行該監控步驟C時，該第一管理單元21會將該第二資訊群組的狀態位元值更改為該第二位元值。It should be particularly noted that, in this embodiment, the first management unit 21 checks and judges the result in the main checking step D1 as Yes (Y) and the checking and judging result in the subordinate checking step D2 as No ( Under the condition of N), the first management unit 21 will execute the synchronous update instruction. In other words, the first management unit 21 judges that the status bit value of an information group in the master hard disk expansion card device 2 is the second bit value and judges that the slave hard disk is not checked. When the state bit value of any information group in the expansion card device 4 is the second bit value, the first management unit 21 will execute the synchronous update command and carry out the synchronous update step E; in other cases, For example: the first management unit 21 judges that the second bit value has not been checked in the main checking step D1, which means that the data of each information group in the main hard disk expansion card device 2 does not exist this time. Update and change, then there is no need to update the backup data to the slave hard disk expansion card device 4, and return to the monitoring step C. Or for example: if it is checked in the slave check step D2 that the status bit value of any information group in the slave hard disk expansion card device 4 is the second bit value, it represents the slave hard disk expansion card device If the data of at least one information group in 4 is updated and changed, then the first management unit 21 sends the acquisition message to obtain the data of the information group corresponding to the second bit value in the slave hard disk expansion card device 4 Go back to the monitoring step C, but not limited thereto. In addition, for example, in this embodiment, the first management unit 21 of the main hard disk expansion card device 2 classifies the I²C status data message into the second information group, and the I²C status data message has the Information about the usage state of the I²C bus (not shown) in the master hard disk expansion card device 2 and the usage status of the I²C bus (not shown) in the slave hard disk expansion card device 4, and when the slave hard disk expands When the I²C state data message in the card device 4 has been updated, the first management unit 21 receives the updated I²C state data message in the slave hard disk expansion card device 4 through the first communication module 23, and updates to itself The corresponding second information group I²C state data message, for example, the I²C state data message of the second information group in the main hard disk expansion card device 2 has six I²C bus lines in the main hard disk expansion card device 2 The usage status and the usage status information of the two I²C buses in the slave hard disk expansion card device 4, when the first management unit 21 receives the information from the slave hard disk expansion card device 4 through the first communication module 23 After the updated I²C status data message, the I²C status data message of the second information group in the master hard disk expansion card device 2 will correspond to the usage status of the two I²C bus bars in the slave hard disk expansion card device 4 to update. At this time, in the main hard disk expansion card device 2, since the I²C state data message of the second information group has been updated, when the monitoring step C is executed next time, the first management unit 21 will The status bit value of the second information group is changed to the second bit value.

附帶一提，本實施例的該檢查步驟中，該第一管理單元是週期性地執行該第一檢查指令與該第二檢查指令，但不以此為限。於本實施例中，該主硬碟擴充卡裝置2的第一管理單元21與該從屬硬碟擴充卡裝置4的第二管理單元41是利用PHY進行通訊與資料傳輸，但不以此為限。Incidentally, in the checking step of this embodiment, the first management unit periodically executes the first checking instruction and the second checking instruction, but not limited thereto. In this embodiment, the first management unit 21 of the master hard disk expansion card device 2 and the second management unit 41 of the slave hard disk expansion card device 4 use PHY for communication and data transmission, but not limited thereto. .

接著，於該同步更新步驟E中，該第一管理單元21執行該同步更新指令且將該主硬碟擴充卡裝置2中的每一狀態位元值為該第二位元值對應的資訊群組中的所有資料經該第一通信模組23傳往該第二通信模組43，並該從屬硬碟擴充卡裝置4的第二管理單元41將該第二通信模組43所接收到所述資料同步更新至對應的資訊群組。簡單來說，就是該主硬碟擴充卡裝置2的第一管理單元21檢查到該主硬碟擴充卡裝置2中有狀態位元值為該第二位元值，而得知該主硬碟擴充卡裝置2中有更改變動資料的資訊群組，該第一管理單元21將第二位元值對應的資訊群組中的所有資料經該第一通信模組23傳往該第二通信模組43，並該第二管理單元41透過該第二通信模組43將所接收到所述資料同步更新至該從屬硬碟擴充卡裝置4中對應的資訊群組。簡單來說，就是該主硬碟擴充卡裝置2只會將為該第二位元值對應的資訊群組中的所有資料傳至該從屬硬碟擴充卡裝置4進行同步更新。Then, in the synchronous update step E, the first management unit 21 executes the synchronous update command and sets each status bit value in the main hard disk expansion card device 2 as the information group corresponding to the second bit value All data in the group are transmitted to the second communication module 43 through the first communication module 23, and the second management unit 41 of the slave hard disk expansion card device 4 receives the second communication module 43 into the The above data is updated to the corresponding information group synchronously. To put it simply, the first management unit 21 of the main hard disk expansion card device 2 checks that the state bit value in the main hard disk expansion card device 2 is the second bit value, and knows that the main hard disk There is an information group for changing data in the expansion card device 2, and the first management unit 21 transmits all the data in the information group corresponding to the second bit value to the second communication module through the first communication module 23. group 43, and the second management unit 41 synchronously updates the received data to the corresponding information group in the slave hard disk expansion card device 4 through the second communication module 43. To put it simply, the master hard disk expansion card device 2 will only transmit all the data in the information group corresponding to the second bit value to the slave hard disk expansion card device 4 for synchronous update.

於該完成步驟F中，當該第一管理單元21將每一狀態位元值為該第二位元值對應的資訊群組中的所有資料傳至該第二通信模組43後，該第一管理單元21將該第二位元值改回該第一位元值。換句話說，當該第一管理單元21將每一狀態位元值為該第二位元值對應的資訊群組中的所有資料經該第一通信模組23傳至該第二通信模組43後，代表已將該主硬碟擴充卡裝置2需要更新備份至該從屬硬碟擴充卡裝置4的資訊群組的所有資料傳完，該第一管理單元21會將該第二位元值改回該第一位元值，而完成此次資料備援的作業。另外一提，於該完成步驟F結束後，經一預設時間，該主硬碟擴充卡裝置2與該從屬硬碟擴充卡裝置4則直接回到該監控步驟C進行下次的資料備援作業，而達成進行週期性的資料備援作業。In the completion step F, when the first management unit 21 transmits all the data in the information group corresponding to the second bit value to the second communication module 43, the second A management unit 21 changes the second bit value back to the first bit value.
