Description
本發明是有關於一種儲存檔案的方法,特別是指一種儲存檔案於一網路儲存裝置的方法。The present invention relates to a method of storing files, and more particularly to a method of storing files in a network storage device.
在網路世界中,UNIX作業系統和Windows作業系統彼此在傳送檔案時,可透過一套架構在NetBIOS(Network Basic Input/Output System)通訊協定上的軟體Samba,來使彼此能夠互相交換資源。In the online world, the UNIX operating system and the Windows operating system can exchange resources with each other through a software Samba that is structured on the NetBIOS (Network Basic Input/Output System) protocol when transferring files to each other.
舉例來說,使用Windows作業系統的電腦透過網路連接使用UNIX作業系統(Linux)的網路儲存裝置,當兩者皆裝設有Samba,而電腦欲將檔案透過Samba儲存到網路儲存裝置時,Samba會先執行預先配置(pre-allocation)動作,以在網路儲存裝置的硬碟中盡可能搜尋一夠大的儲存空間來存放檔案,使得檔案不會被零散地儲存於硬碟,並以特定的容量大小將檔案整體或分散的儲存於硬碟,如此一來,在讀取檔案時會有較好的效能。For example, a computer using a Windows operating system uses a UNIX operating system (Linux) network storage device via a network connection, when both are equipped with Samba, and the computer wants to store the file through Samba to the network storage device. Samba will perform a pre-allocation action to search for a large enough storage space on the network storage device's hard drive to store the files so that the files are not scattered on the hard disk. The files are stored on the hard disk in a specific capacity or in a distributed manner, so that the file will have better performance when the file is read.
然而,此預先配置動作會消耗網路儲存裝置的中央處理單元(Central Processing Unit,CPU)的資源,如果網路儲存裝置的硬碟本身已無夠大的儲存空間,而依舊執行預先配置動作的話,無疑是造成網路儲存裝置的CPU不必要的負擔,因此,如何有效地運用預先配置動作將是一值得研究改進的課題。However, this pre-configuration action consumes the resources of the central processing unit (CPU) of the network storage device. If the hard disk of the network storage device itself does not have enough storage space, and the pre-configured action is still performed, It is undoubtedly an unnecessary burden on the CPU of the network storage device. Therefore, how to effectively use the pre-configured action will be a problem worthy of research and improvement.
因此,本發明之目的,即在提供一種彈性使用預先配置動作的儲存檔案於一網路儲存裝置的方法。Accordingly, it is an object of the present invention to provide a method of resiliently storing a file of a pre-configured action in a network storage device.
於是,本發明儲存檔案於一網路儲存裝置的方法,應用於具有一儲存單元的網路儲存裝置,該方法包含:Therefore, the method for storing a file in a network storage device of the present invention is applied to a network storage device having a storage unit, the method comprising:
(A)於網路儲存裝置在儲存一檔案時,先執行一預先配置動作,以在儲存單元中搜尋是否有一特定大小的儲存空間,若是,則儲存檔案於該儲存空間,若否,則進行步驟(B);(A) when the network storage device stores a file, first perform a pre-configuration action to search the storage unit for a specific size storage space, and if so, store the file in the storage space, if not, proceed Step (B);
(B)於網路儲存裝置的一記憶模組中累計一次失敗次數,並且判斷累計的失敗次數是否達到一第一預設次數,若是,則停止執行預先配置動作並直接儲存檔案於儲存單元,若否,則進行步驟(C);及(B) accumulating the number of failures in a memory module of the network storage device, and determining whether the accumulated number of failures reaches a first predetermined number of times, and if so, stopping the pre-configuring action and directly storing the file in the storage unit. If no, proceed to step (C); and
(C)重新執行預先配置動作以搜尋儲存單元中是否有一較前次搜尋的儲存空間小的次儲存空間,若是,則儲存檔案於次儲存空間,若否,則重覆步驟(B)。(C) Re-execute the pre-configuration action to search whether the storage unit has a smaller storage space than the previous searched storage space, and if so, store the file in the secondary storage space, and if not, repeat step (B).
本發明之另一目的,在於提供一種應用上述之方法的網路儲存裝置。Another object of the present invention is to provide a network storage device using the above method.
於是,本發明網路儲存裝置,包含一存取介面、一儲存單元、一控制模組、一記憶模組及一處理模組,存取介面能接收來自電子裝置的檔案,儲存單元儲存存取介面所接收的檔案,控制模組在存取介面接收一檔案時會執行一預先配置動作,以在儲存單元中搜尋一特定大小的儲存空間,而當控制模組執行儲存檔案的預先配置動作失敗時,記憶模組會累計一次的失敗次數,處理模組會判斷記憶模組所累計的失敗次數是否達到一第一預定次數,若是,則令控制模組停止執行預先配置動作並直接儲存檔案於儲存單元,若否,則令控制模組重新執行預先配置動作,以搜尋一較前次搜尋的儲存空間小的次儲存空間。Therefore, the network storage device of the present invention comprises an access interface, a storage unit, a control module, a memory module and a processing module. The access interface can receive files from the electronic device, and the storage unit stores the access. The file received by the interface, the control module performs a pre-configured action when the access interface receives a file to search for a specific size storage space in the storage unit, and the control module fails to perform the pre-configured action of storing the file. When the memory module accumulates the number of failures, the processing module determines whether the number of failures accumulated by the memory module reaches a first predetermined number of times. If so, the control module stops performing the pre-configured action and directly stores the file. The storage unit, if not, causes the control module to re-execute the pre-configured action to search for a secondary storage space that is smaller than the previously searched storage space.
本發明之功效在於,儲存檔案於一網路儲存裝置的方法能應用於網路儲存裝置,使網路儲存裝置在儲存檔案前的預先配置動作能彈性地被使用,藉此控管網路儲存裝置的中央處理單元之效能,使得網路儲存裝置能順利地運作。The method of the present invention is that the method for storing a file in a network storage device can be applied to a network storage device, so that the pre-configured action of the network storage device before storing the file can be flexibly used, thereby controlling the network storage. The performance of the central processing unit of the device enables the network storage device to operate smoothly.
有關本發明之前述及其他技術內容、特點與功效,在以下配合參考圖式之二個較佳實施例的詳細說明中,將可清楚的呈現。The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention.
在本發明被詳細描述之前,要注意的是,在以下的說明內容中,類似的元件是以相同的編號來表示。Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals.
參閱圖1,為本發明儲存檔案於一網路儲存裝置的方法之第一較佳實施例,該方法應用於一網路儲存裝置2,網路儲存裝置2與電子裝置3藉網路連接並且皆裝設有Samba,網路儲存裝置2與電子裝置3能透過Samba相互傳送檔案,在本實施例中,該方法是以一軟體程式實現,該軟體程式可整合於Samba軟體中,亦可與Samba相互獨立運作。在本實施例中,網路儲存裝置2為UNIX作業系統(Linux)的NAS(Network Attached Storage),亦可為其他網路伺服器,而電子裝置3為Windows作業系統的電腦或其他可以連接上網的電子裝置。Referring to FIG. 1 , a first preferred embodiment of a method for storing a file in a network storage device according to the present invention is applied to a network storage device 2, and the network storage device 2 is connected to the electronic device 3 via a network and Samba is installed, and the network storage device 2 and the electronic device 3 can transmit files through Samba. In this embodiment, the method is implemented by a software program, which can be integrated into the Samba software, or Samba operates independently of each other. In this embodiment, the network storage device 2 is a NAS (Network Attached Storage) of a UNIX operating system (Linux), and may be another network server, and the electronic device 3 is a computer of the Windows operating system or other Internet connection. Electronic device.
參閱圖2,網路儲存裝置2包含一存取介面21、一儲存單元(在本實施例是以硬碟22為例,但不以此為限)及一中央處理單元23,存取介面21、硬碟22及中央處理單元23三者相互耦接,其中,存取介面21是用以接收來自網路上電子裝置3的檔案,硬碟22包含一能儲存存取介面21所接收之檔案的儲存模組221及一記憶模組222,中央處理單元23包含一控制模組231及一處理模組233,而上述之功能區塊的作用將在下面做進一步說明。Referring to FIG. 2, the network storage device 2 includes an access interface 21, a storage unit (in this embodiment, the hard disk 22 is taken as an example, but not limited thereto), and a central processing unit 23, the access interface 21 The hard disk 22 and the central processing unit 23 are coupled to each other. The access interface 21 is for receiving files from the electronic device 3 on the network, and the hard disk 22 includes a file capable of storing the file received by the access interface 21. The storage module 221 and a memory module 222, the central processing unit 23 includes a control module 231 and a processing module 233, and the functions of the above functional blocks will be further described below.
配合參閱圖2及圖3,當電子裝置3欲將一檔案(例如:9GB)傳送至網路儲存裝置2時,首先,網路儲存裝置2的存取介面21接收檔案,之後,如步驟901所示,由於作業系統會記錄中央處理單元23的目前使用率,故中央處理單元23的處理模組233可讀取作業系統所記錄之中央處理單元23的目前使用率,並判斷中央處理單元23的使用率是否達到一預設值(例如:80%),若是,則處理模組233令控制模組231將存取介面21所接收的檔案不經Samba執行預先配置(pre-allocation)動作即直接儲存於硬碟22的儲存模組221,如步驟902;若否,則處理模組233接著判斷記憶模組222中累計執行預先配置(pre-allocation)動作的失敗總次數是否達到一第二預設次數,如步驟903,而關於失敗總次數的定義請容後說明。若失敗總次數達到第二預設值,則處理模組233令控制模組231將存取介面21所接收的檔案不經Samba執行預先配置(pre-allocation)動作即直接儲存於硬碟22的儲存模組221,如步驟904;若失敗總次數未達到第二預設值,則進行步驟905。Referring to FIG. 2 and FIG. 3, when the electronic device 3 wants to transfer a file (for example, 9 GB) to the network storage device 2, first, the access interface 21 of the network storage device 2 receives the file, and then, as in step 901. As shown, since the operating system records the current usage rate of the central processing unit 23, the processing module 233 of the central processing unit 23 can read the current usage rate of the central processing unit 23 recorded by the operating system, and determine the central processing unit 23 Whether the usage rate reaches a preset value (for example, 80%), and if so, the processing module 233 causes the control module 231 to perform the pre-allocation action of the file received by the access interface 21 without Samba. The storage module 221 is directly stored in the hard disk 22, as in step 902. If not, the processing module 233 then determines whether the total number of failed pre-allocation actions in the memory module 222 reaches a second. The preset number of times, as in step 903, and the definition of the total number of failures, please explain later. If the total number of failures reaches the second preset value, the processing module 233 causes the control module 231 to store the file received by the access interface 21 directly on the hard disk 22 without performing a pre-allocation action by Samba. The storage module 221 is as shown in step 904. If the total number of failures does not reach the second preset value, step 905 is performed.
在步驟905中,處理模組233令控制模組231執行Samba並執行預先配置(pre-allocation)動作以搜尋硬碟22的儲存模組221中是否有一使檔案不必分散地儲存於硬碟22的儲存模組221之大於該檔案大小的儲存空間(例如:10GB),然後,若控制模組231執行預先配置動作成功,則執行步驟906,處理模組233令控制模組231將檔案儲存於搜尋到的儲存空間;若控制模組231執行預先配置動作失敗,則執行步驟907,處理模組233令記憶模組222累計一次的失敗次數。接著,於步驟907後進行步驟908,如步驟908所示,處理模組233會先判斷記憶模組222累計的失敗次數是否達到一第一預設次數,若是,則處理模組233令控制模組231停止執行預先配置(pre-allocation)動作並將存取介面21所接收的檔案直接儲存於硬碟22的儲存模組221,如步驟909;若否,則處理單元233令控制模組231重新執行預先配置動作以搜尋硬碟22的儲存模組221中是否有一較前次搜尋的儲存空間小的次儲存空間(例如:8GB),如步驟910。In step 905, the processing module 233 causes the control module 231 to execute Samba and perform a pre-allocation action to search the storage module 221 of the hard disk 22 for storing the file on the hard disk 22 without being distributed. The storage module 221 is larger than the storage size of the file (for example, 10 GB). Then, if the control module 231 performs the pre-configuration operation successfully, step 906 is executed, and the processing module 233 causes the control module 231 to store the file in the search. If the control module 231 fails to perform the pre-configuration operation, step 907 is executed, and the processing module 233 causes the memory module 222 to accumulate the number of failures. Then, after step 907, step 908 is performed. As shown in step 908, the processing module 233 first determines whether the number of failures accumulated by the memory module 222 reaches a first predetermined number of times. If so, the processing module 233 causes the control module to The group 231 stops performing the pre-allocation operation and stores the file received by the access interface 21 directly in the storage module 221 of the hard disk 22, as in step 909; if not, the processing unit 233 causes the control module 231 to execute the control module 231. The pre-configured action is re-executed to search whether the storage module 221 of the hard disk 22 has a smaller storage space (for example, 8 GB) than the previous searched storage space, as in step 910.
在步驟910中,若控制模組231執行預先配置動作成功,如步驟911所示,處理模組233令控制模組231將檔案儲存於搜尋到的次儲存空間,此時,由於次儲存空間小於檔案大小,所以檔案將被分散儲存,而檔案剩餘的部分將藉同樣的方法由步驟901開始尋找硬碟22的儲存模組221中一適合的儲存空間;若控制模組231執行預先配置動作失敗,將重新執行步驟907,直到步驟908判斷累計的失敗次數達到第一預設次數,或是重新執行步驟907的預先配置動作已搜尋到更小的次儲存空間。之後,不論是執行步驟909或是步驟911都會進入步驟912,處理模組233令記憶模組222將累計的失敗次數加入失敗總次數,而失敗總次數即是指網路儲存裝置2在儲存每一檔案所執行預先配置(pre-allocation)動作失敗次數的總和,最後,執行步驟913,處理模組233令記憶模組222將失敗次數歸零,即完成檔案儲存作業。其中上述的第一預設次數、第二預設次數與預設值可透過內部程式設定完成。In step 910, if the control module 231 performs the pre-configuration operation successfully, as shown in step 911, the processing module 233 causes the control module 231 to store the file in the searched secondary storage space. The file size, so the file will be stored in a distributed manner, and the remaining part of the file will be searched for a suitable storage space in the storage module 221 of the hard disk 22 by the same method; if the control module 231 fails to perform the pre-configuration operation Step 907 will be re-executed until step 908 determines that the accumulated number of failures reaches the first predetermined number of times, or re-executes the pre-configured action of step 907 to search for a smaller secondary storage space. Then, whether step 909 or step 911 is performed, the process module 233 causes the memory module 222 to add the accumulated number of failures to the total number of failures, and the total number of failures refers to the network storage device 2 storing each time. The sum of the number of failed pre-allocation actions performed by a file. Finally, in step 913, the processing module 233 causes the memory module 222 to reset the number of failures to zero, that is, to complete the file storage operation. The first preset number of times, the second preset number of times, and the preset value may be completed by an internal program setting.
附帶說明的是,於步驟902中,不經Samba執行預先配置(pre-allocation)動作時,則控制模組233是將檔案直接儲存於硬碟22的儲存模組221零星或分散的儲存空間中,但是同時處理模組233還是會繼續判斷中央處理單元23的使用率,一旦使用率低於預設值,處理模組233將令控制模組231先暫停儲存檔案,而進行步驟903,判斷是否能先執行預先配置(pre-allocation)動作,因為如能透過預先配置動作來儲存檔案,之後在讀取或利用檔案時會有較佳的效能。此外,由於步驟901與步驟903兩者判斷機制並無先後關係,而且步驟902與步驟904相同,所以亦可先執行步驟903再執行步驟901,其執行先後順序可視實際應用情況調整。It should be noted that, in step 902, when the pre-allocation action is not performed by Samba, the control module 233 stores the file directly in the sporadic or scattered storage space of the storage module 221 of the hard disk 22. However, the processing module 233 will continue to determine the usage rate of the central processing unit 23. Once the usage rate is lower than the preset value, the processing module 233 will cause the control module 231 to suspend the storage of the file first, and step 903 is performed to determine whether Perform pre-allocation actions first, because if you can save files through pre-configured actions, then you will have better performance when reading or using files. In addition, since there is no relationship between the determining mechanism of step 901 and step 903, and step 902 is the same as step 904, step 903 may be performed first and then step 901 may be performed, and the sequence of execution may be adjusted according to actual application conditions.
值得說明的是,當網路儲存裝置2的中央處理單元23同時處理很多事情(例如:執行傳送接收檔案的加解密功能或同時有多數個電子裝置在存取檔案)而使用率過高時,能透過步驟901的設定,在儲存檔案方面,採用直接將檔案儲存至硬碟22的儲存模組221中,而不需執行預先配置(pre-allocation)動作,將使中央處理單元23減輕負擔正常運作,而不會因負載過度而當機。It should be noted that when the central processing unit 23 of the network storage device 2 processes a lot of things at the same time (for example, performing the encryption and decryption function of transmitting and receiving files or having a plurality of electronic devices accessing files at the same time) and the usage rate is too high, Through the setting of step 901, in the storage of the file, the file is directly stored in the storage module 221 of the hard disk 22 without performing a pre-allocation action, so that the central processing unit 23 can reduce the burden. Operate without crashing due to excessive load.
再者,當記憶模組222累計的失敗總次數過多時,代表硬碟22的儲存模組221中所剩餘的空間不多或是剩餘的空間為零碎的小空間,此時,若繼續於儲存每一檔案前執行預先配置動作將會徒勞無功,反而浪費中央處理單元23的資源,因此,透過步驟903的設定,將可以在執行預先配置動作之前,先藉失敗總次數判讀硬碟22的儲存模組221的狀態,若失敗總次數過高,則不需執行預先配置動作,改將檔案直接儲存至硬碟22的儲存模組221中,以減輕中央處理單元23的負擔。Moreover, when the total number of failures accumulated by the memory module 222 is too large, there is not much space left in the storage module 221 representing the hard disk 22 or a small space in which the remaining space is fragmented. Performing the pre-configured action in front of each file will be useless, but will waste the resources of the central processing unit 23. Therefore, through the setting of step 903, the storage mode of the hard disk 22 can be interpreted by the total number of failures before performing the pre-configured action. If the total number of failures is too high, the status of the group 221 is not required to be pre-configured, and the file is directly stored in the storage module 221 of the hard disk 22 to reduce the burden on the central processing unit 23.
此外,當失敗總次數達到第二預設次數後,本發明儲存檔案於一網路儲存裝置的方法更可執行一於步驟904之後的步驟914,如步驟914所示,處理模組233判斷硬碟22的儲存模組221是否釋出一特定大小的儲存空間,若是,則將失敗總次數歸零。在此步驟中,處理模組233會判斷硬碟22的儲存模組221中是否增加一特定的儲存空間,像是硬碟22的儲存模組221中的檔案被刪除或是硬碟22的儲存模組221經磁碟重組而釋放空間,若是,處理模組233令記憶模組222的失敗總次數歸零,如步驟915,如此一來,當有檔案需存入硬碟22的儲存模組221時,則又可以開始執行圖3本實施例之步驟;若否,則重複步驟914,處理模組233繼續判斷硬碟22的儲存模組221中是否增加一特定的儲存空間。其中,特定的儲存空間是可透過內部程式,按照釋放空間與硬碟22的儲存模組221所剩容量的比例來設定,舉例來說,當處理模組233判斷釋放空間超過硬碟22的儲存模組221所剩容量的20%,則將失敗總次數歸零。In addition, after the total number of failures reaches the second predetermined number of times, the method for storing the file in a network storage device of the present invention can be further performed in step 914 after step 904. As shown in step 914, the processing module 233 determines the hard Whether the storage module 221 of the disc 22 releases a storage space of a certain size, and if so, zeros the total number of failures. In this step, the processing module 233 determines whether a specific storage space is added to the storage module 221 of the hard disk 22. For example, the file in the storage module 221 of the hard disk 22 is deleted or the storage of the hard disk 22 is stored. The module 221 is reorganized by the disk to release the space. If so, the processing module 233 resets the total number of failures of the memory module 222 to zero, as in step 915, so that when there is a file to be stored in the storage module of the hard disk 22 At 221, the step of the embodiment of FIG. 3 can be started. If no, step 914 is repeated. The processing module 233 continues to determine whether a specific storage space is added to the storage module 221 of the hard disk 22. The specific storage space is set by the internal program according to the ratio of the release space to the remaining capacity of the storage module 221 of the hard disk 22. For example, when the processing module 233 determines that the release space exceeds the storage of the hard disk 22 If 20% of the remaining capacity of the module 221 is zero, the total number of failures is zeroed.
參閱圖4,是本實施例的一變化實施例,亦即調整步驟903、步驟904、步驟914及步驟915的執行順序同樣可達到如同上述的功效,詳細說明如下。將步驟903調整至步驟912之後,若處理單元233判斷累計執行預先配置(pre-allocation)動作的失敗總次數達到第二預設次數,則令執行模組231在執行後續收到的檔案儲存時,則停止執行預先配置(pre-allocation)動作而直接將後續收到的檔案儲存至硬碟22的儲存模組221中,如步驟916,並進行步驟913;若未達到第二預設次數,則進行步驟913。此外,在執行步驟916之後,會進行步驟914及步驟915,如先前所述以將失敗總次數歸零,而能夠啟動預先配置(pre-allocation)動作,於是,經過步驟的調整,同樣可達到上述之功效。Referring to FIG. 4, a modified embodiment of the present embodiment, that is, the execution sequence of the adjustment step 903, the step 904, the step 914, and the step 915 can also achieve the same functions as described above, and the details are as follows. After the step 903 is adjusted to the step 912, if the processing unit 233 determines that the total number of failed executions of the pre-allocation action reaches the second preset number of times, the execution module 231 causes the subsequent received file storage to be executed. If the pre-configuration (pre-allocation) action is stopped, the subsequently received file is directly stored in the storage module 221 of the hard disk 22, as in step 916, and step 913 is performed; if the second preset number of times is not reached, Then proceed to step 913. In addition, after step 916 is performed, step 914 and step 915 are performed, and as described above, the total number of failures is zeroed, and a pre-allocation action can be initiated, and thus, after the adjustment of the steps, the same can be achieved. The above effects.
參閱圖5,為本發明儲存檔案於一網路儲存裝置的方法之第二較佳實施例,該方法應用於一網路儲存裝置2,網路儲存裝置2與多數個電子裝置3藉網路連接並且皆裝設有Samba,網路儲存裝置2與多數個電子裝置3能透過Samba相互傳送檔案,本實施例儲存檔案於一網路儲存裝置的方法是以一軟體程式實現,該軟體程式可整合於Samba軟體中,也可以與Samba相互獨立運作。在本實施例中,網路儲存裝置2與多數個電子裝置3可架構成一區域網路架構,使電子裝置3共享網路儲存裝置2的資源及儲存容量。Referring to FIG. 5, a second preferred embodiment of a method for storing a file in a network storage device according to the present invention is applied to a network storage device 2, and the network storage device 2 and a plurality of electronic devices 3 borrow a network. Samba is connected and installed, and the network storage device 2 and the plurality of electronic devices 3 can transmit files through Samba. The method for storing files in a network storage device in this embodiment is implemented by a software program, and the software program can be implemented. Integrated into Samba software, it can also operate independently of Samba. In this embodiment, the network storage device 2 and the plurality of electronic devices 3 can be configured to form a regional network architecture, so that the electronic device 3 shares the resources and storage capacity of the network storage device 2.
在每一電子裝置3欲儲存檔案至網路儲存裝置2時,同樣地會執行如同圖3之第一較佳實施例的判斷是否執行預先配置(pre-allocation)動作的步驟,而第二較佳實施例與第一較佳實施例的差異在於網路儲存裝置2設有互斥機制,亦即處理模組233會避免多個電子裝置3同時在記憶模組222中寫入失敗總次數而發生失敗總次數錯誤的情況,而其餘的流程步驟與第一較佳實施例相同。When each electronic device 3 wants to store a file to the network storage device 2, the same step as the first preferred embodiment of FIG. 3 is performed to determine whether to perform a pre-allocation action, and the second comparison is performed. The difference between the preferred embodiment and the first preferred embodiment is that the network storage device 2 is provided with a mutual exclusion mechanism, that is, the processing module 233 can prevent the total number of write failures of the plurality of electronic devices 3 in the memory module 222 at the same time. The case where the total number of failures is erroneous occurs, and the remaining flow steps are the same as in the first preferred embodiment.
