Embodiment
About aforementioned and other technology contents, characteristics and effect of the present invention, in the detailed description of following cooperation two preferred embodiments with reference to the accompanying drawings, can clearly present.
Before the present invention is described in detail, be noted that in the following description content similarly assembly is to represent with identical numbering.
Consult Fig. 1, Fig. 1 is that store files of the present invention is in first preferred embodiment of the method for a network storage devices, this method is applied to a network storage devices 2, network storage devices 2 is with electronic installation 3 mat network connections and all be equiped with Samba, network storage devices 2 can transmit file by Samba mutually with electronic installation 3, and in the present embodiment, this method is to realize with a software program, this software program can be integrated in the Samba software, also can with the separate work of Samba.In the present embodiment, network storage devices 2 is NAS (the Network AttachedStorage of UNIX operating system (Linux), the network attached storage device), also can be other webservers, and electronic installation 3 can connect the electronic installation of online for the computer of Windows operating system or other.
Consult Fig. 2, network storage devices 2 comprises an access interface 21, one storage element (is to be example with hard disk 22 in the present embodiment, but not as limit) and a CPU 23, access interface 21, hard disk 22 and CPU 23 threes couple mutually, wherein, access interface 21 is in order to receive the power on file of sub-device 3 of automatic network, hard disk 22 comprises storage module 221 and a memory module 222 that can store the file that access interface 21 receives, CPU 23 comprises a control module 231 and a processing module 233, and the effect of above-mentioned functional block will be described further below.
Cooperate and consult Fig. 2 and Fig. 3, when electronic installation 3 desires with a file (for example: when 9GB) being sent to network storage devices 2, at first, the access interface 21 of network storage devices 2 receives file, afterwards, shown in step 901, because operating system can record the present utilization rate of CPU 23, so the processing module 233 of CPU 23 can read the present utilization rate of the CPU 23 that operating system records, and whether the utilization rate of judging CPU 23 (for example: 80%) reaches a preset value, if, then processing module 233 makes control module 231 that the file that access interface 21 receives is carried out the storage module 221 that pre-configured action namely directly is stored in hard disk 22 without Samba, as step 902; If not, then processing module 233 judges then whether the failure total degree of totally carrying out pre-configured action in the memory module 222 reaches one second preset times, as step 903, and please hold the back explanation about the definition of failure total degree.If the failure total degree reaches second preset value, then processing module 233 makes control module 231 that the file that access interface 21 receives is carried out the storage module 221 that pre-configured action namely directly is stored in hard disk 22 without Samba, as step 904; If the failure total degree does not reach second preset value, then carry out step 905.
In step 905, processing module 233 make control module 231 carry out Samba and carry out whether have in the storage module 221 of pre-configured action with search hard disk 22 one make file needn't be stored in dispersedly hard disk 22 storage module 221 greater than the storage area of this document size (for example: 10GB), then, if control module 231 is carried out pre-configured the action successfully, then execution in step 906, and processing module 233 makes control module 231 file is stored in the storage area that searches; If control module 231 is carried out pre-configured baulk, then execution in step 907, and processing module 233 makes the memory module 222 accumulative totals frequency of failure once.Then, after step 907, carry out step 908, shown in step 908, processing module 233 can judge earlier whether the frequency of failure of memory module 222 accumulative totals reaches one first preset times, if, then processing module 233 makes control module 231 stop to carry out pre-configured action and the file that access interface 21 receives directly is stored in the storage module 221 of hard disk 22, as step 909; If not, then processing module 233 make control module 231 re-execute whether having in the storage module 221 of pre-configured action with search hard disk 22 one more last time the little inferior storage area, storage area of search (for example: 8GB), as step 910.
In step 910, if control module 231 is carried out pre-configured the action successfully, shown in step 911, processing module 233 makes control module 231 file is stored in the inferior storage area that searches, at this moment, because time storage area is less than file size, so file will be disperseed to store, and file rest parts method that mat is same is begun to seek a storage area that is fit in the storage module 221 of hard disk 22 by step 901; If control module 231 is carried out pre-configured baulk, will re-execute step 907, judge that up to step 908 frequency of failure of accumulative total reaches first preset times, or the pre-configured action that re-executes step 907 has searched littler inferior storage area.Afterwards, no matter be that execution in step 909 or step 911 all can enter step 912, processing module 233 makes memory module 222 that the frequency of failure of accumulative total is added the failure total degree, and the failure total degree refers to that namely network storage devices 2 is in the summation that stores the performed pre-configured baulk number of times of each file, at last, execution in step 913, processing module 233 make memory module 222 that the frequency of failure is made zero, and namely finish the file store operation.Wherein above-mentioned first preset times, second preset times and preset value can be finished by the internal processes setting.
Additional disclosure be, in step 902, when carrying out pre-configured action without Samba, then control module 231 is that file directly is stored in the fragmentary or storage area that disperses of the storage module 221 of hard disk 22, but processing module 233 still can continue to judge the utilization rate of CPU 23 simultaneously, in case utilization rate is lower than preset value, processing module 233 military order control modules 231 are suspended store files earlier, and carry out step 903, judge whether to carry out pre-configured action earlier, because if can come store files by pre-configured action, when reading or utilize file, have preferable usefulness afterwards.In addition, because step 901 and both judgment mechanisms of step 903 there is no precedence relationship, and step 902 is identical with step 904, thus also can first execution in step 903 execution in step 901 again, the visual practical situations adjustment of its execution sequencing.
What deserves to be explained is, when the CPU 23 of network storage devices 2 is handled a lot of things (for example: carry out to transmit receive the encryption and decryption functions of file or a plurality of electronic installations are arranged simultaneously at accessing file) and utilization rate when too high simultaneously, can be by the setting of step 901, aspect store files, adopt and directly file is stored in the storage module 221 of hard disk 22, and need not carry out pre-configured action, to make CPU 23 operate as normal that reduces the heavy burdens, and can be excessively unexpected of machine (crash) because of load.
Moreover, when the failure total degree of memory module 222 accumulative totals is too much, it is few or remaining space is scrappy little space to represent space remaining in the storage module 221 of hard disk 22, at this moment, if continuing to carry out before storing each file pre-configured action will make a futile effort, waste the resource of CPU 23 on the contrary, therefore, setting by step 903, can be before carrying out pre-configured action, the state of the storage module 221 of elder generation's mat failure total degree interpretation hard disk 22, if the failure total degree is too high, then need not carry out pre-configured action, change file directly is stored in the storage module 221 of hard disk 22, to alleviate the burden of CPU 23.
In addition, after the failure total degree reaches second preset times, store files of the present invention also can be carried out a step 914 after step 904 in the method for a network storage devices, shown in step 914, processing module 233 judges whether the storage module 221 of hard disk 22 disengages the storage area of a specific size, if the total degree of then will failing makes zero.In this step, processing module 233 understands in the storage module 221 that judge hard disk 22 whether increase by a specific storage area, similarly be that the deleted or storage module 221 of hard disk 22 of file in the storage module 221 of hard disk 22 is through the disk reorganization and Free up Memory, if, processing module 233 makes the failure total degree of memory module 222 make zero, as step 915, thus, when file need deposit the storage module 221 of hard disk 22 in, then can begin to carry out the step of present embodiment shown in Figure 3 again; If not, then repeating step 914, and processing module 233 continues to judge in the storage module 221 of hard disk 22 whether increase by a specific storage area.Wherein, specific storage area is to pass through internal processes, ratio according to the storage module 221 last capacity of Free up Memory and hard disk 22 is set, for instance, when processing module 233 judge Free up Memories surpass hard disk 22 storage module 221 last capacity 20%, the total degree of then will failing makes zero.
Consult Fig. 4, Fig. 4 is an alternate embodiment of present embodiment, that is the execution sequence of set-up procedure 903, step 904, step 914 and step 915 can reach equally as above-mentioned effect, is described in detail as follows.Step 903 is adjusted to after the step 912, if processing unit 233 is judged accumulative total and is carried out the failure total degree of pre-configured action and reach second preset times, then make control module 231 when the follow-up file of receiving of execution stores, then stop to carry out pre-configured action and directly the follow-up file of receiving is stored in the storage module 221 of hard disk 22, as step 916, and carry out step 913; If do not reach second preset times, then carry out step 913.In addition, after execution in step 916, can carry out step 914 and step 915, as discussed previouslyly make zero with the total degree of will failing, and can start pre-configured action, so the adjustment through step can reach above-mentioned effect equally.
Consult Fig. 5, Fig. 5 is that store files of the present invention is in second preferred embodiment of the method for a network storage devices, this method is applied to a network storage devices 2, network storage devices 2 is with a plurality of electronic installation 3 mat network connections and all be equiped with Samba, network storage devices 2 can transmit file by Samba mutually with a plurality of electronic installations 3, the present embodiment store files is to realize with a software program in the method for a network storage devices, this software program can be integrated in the Samba software, also can with the separate work of Samba.In the present embodiment, network storage devices 2 can be configured to a LAN framework with a plurality of electronic installations 3, makes resource and the storage volume of electronic installation 3 shared network storage devices 2.
When each electronic installation 3 is desired store files to network storage devices 2, similarly can carry out the step that judges whether to carry out pre-configured action as first preferred embodiment of Fig. 3, and the difference of second preferred embodiment and first preferred embodiment is that network storage devices 2 is provided with mutual exclusion mechanism, that is processing module 233 can avoid a plurality of electronic installations 3 to write the failure total degree simultaneously and the situation of the total degree mistake of failing in memory module 222, and remaining process step is identical with first preferred embodiment.
In sum, store files of the present invention can be applied to network storage devices 2 in the method for a network storage devices, the pre-configured action of network storage devices 2 before store files can efficiently be reached to be used neatly, the usefulness of the CPU 23 of keyholed back plate network storage devices 2 by this, make network storage devices 2 successfully to work, so can reach purpose of the present invention really.
The above person of thought, it only is preferred embodiment of the present invention, can not limit scope of the invention process with this, i.e. the every scope of claims and simple equivalent variations and modification that the invention description content is done according to the present invention all still belongs in the scope that patent of the present invention contains.
