[0031] Embodiment 1

[0032] Figure 1 This is a flowchart of a file storage method provided in the first embodiment of the present invention. This embodiment is applicable to the case of storing files in an application system on an operating system, and is particularly applicable to the case of storing large files (i.e., files with a size ranging from 10MB to 5GB) in an application system on an operating system. The method can be executed by a file storage device, which can be implemented in the form of hardware and / or software and can be configured in an electronic device. Figure 1As shown, the method includes:

[0033] S101. After a monitoring interface monitors a file saving event, obtain relevant file information corresponding to the file saving event; wherein the relevant file information includes the file to be stored, the file storage capacity, the file storage disk, and the original host to which the file storage disk belongs.

[0034] Among them, the monitoring interface refers to an interface specifically used to monitor file saving events in the application system; optionally, the monitoring interface can be pre-configured in the operating system according to actual business needs, for example, the monitoring interface can be inotify in the Linux system. The application system refers to the system running on the operating system, for example, the application system can be a management system for managing construction industry projects, or a game, chat software or browser.

[0035] The file to be stored refers to the file that needs to be stored. The file storage capacity refers to the capacity required to store the file to be stored; optionally, the file storage capacity can be determined according to the file size of the file to be stored. The file storage disk refers to the disk specified in the original file save path of the file to be stored. For example, if the original file save path of the file to be stored is C: / upload / data / test.txt, then the file storage disk is the C drive. The original file save path refers to the file save path recorded in the file save event.

[0036] Specifically, after the monitoring interface monitors the file saving event, the file saving event is captured, and relevant file information is extracted from the file saving event.

[0037] S102. When it is detected that the remaining disk capacity of the file storage disk does not meet the file storage capacity, and the remaining disk capacity of the candidate disks in the original host does not meet the file storage capacity, determine the target LAN where the original host is located, and broadcast the file transfer information of the file to be stored to the candidate hosts in the target LAN.

[0038] Among them, the candidate disk refers to the disk other than the file storage disk in the original host; the candidate host refers to the host other than the original host in the target LAN. It should be noted that the number of candidate hosts is at least one. The target LAN refers to the LAN where the original host is located. File transfer information refers to information related to the transfer of the file to be stored; optionally, the file transfer information includes but is not limited to the file name of the file to be stored, the file storage capacity, the original file storage address and the original host name.

[0039] Specifically, when it is detected that the remaining disk capacity of the file storage disk is less than the file storage capacity, and the remaining disk capacity of the candidate disks in the original host is less than the file storage capacity, the IP address (Internet Protocol Address) of the original host is obtained, and based on the correspondence between the candidate LANs and the IP address ranges in the LAN setting table, according to the IP address of the original host, the target LAN where the original host is located is determined from at least one candidate LAN in the LAN setting table; thereafter, the file transfer information of the file to be stored can be broadcast to the candidate hosts in the target LAN based on the LAN broadcast method.

[0040] Among them, the candidate LAN refers to the LAN pre-set in the LAN setting table. It should be noted that the LAN setting table can be pre-configured according to actual business needs, and the embodiment of the present invention does not specifically limit it. The LAN broadcast mode can be pre-set according to actual business needs. For example, the LAN broadcast mode can be a UDP (User Datagram Protocol) broadcast mode. For example, the LAN broadcast mode can be a LAN broadcast mechanism built into the operating system.

[0041] Optionally, in order to quickly propagate file transfer information in the target LAN and reduce network latency, the file transfer information of the files to be stored can also be broadcast to the candidate hosts in the target LAN through a private KCP (Kernel Control Protocol) protocol. The private KCP protocol can be obtained by modifying the standard KCP protocol according to actual business needs.

[0042] S103: Determine an available host that meets the file storage capacity from at least one responding host according to the received response information sent by the responding host.

[0043] Among them, the responding host refers to the candidate host that responds to the file transfer information in the target local area network. The response information includes the remaining capacity of the host disk. Among them, the remaining capacity of the host disk refers to the remaining capacity of the responding host disk. For each responding host, the remaining capacity of the host disk can be equal to the sum of the remaining capacity of each disk in the responding host, or it can be equal to the largest remaining capacity of the remaining capacity of each disk in the responding host, or it can be equal to the average or median of the remaining capacity of each disk in the responding host. It should be noted that one candidate host sends one response message. A responding host includes at least one disk. An available host refers to a responding host whose remaining capacity of the host disk is greater than or equal to the file storage capacity.

[0044] Optionally, the response information also includes the total number of disks of the responding host, the remaining disk capacity and disk storage speed of each disk in the responding host, and the network status of the responding host.

[0045] Specifically, available hosts that meet the file storage capacity may be screened out from at least one responding host according to the remaining capacity of the host disk of each responding host.

[0046] More specifically, based on the remaining capacity of the host disks of the responding hosts, available hosts whose remaining capacity of the host disks is greater than or equal to the file storage capacity may be screened out from at least one responding host.

[0047] It is understandable that not all responding hosts in the target LAN have a host disk remaining capacity that satisfies the file storage capacity. Therefore, based on the host disk remaining capacity of each responding host, available hosts that meet the file storage capacity are screened out from at least one responding host, which can further narrow the host range for determining the target host, thereby speeding up the determination of the target host.

[0048] Optionally, if the response information sent by the responding host is not received within the preset time, the file transfer information of the file to be stored is broadcasted again to the candidate hosts in the target local area network until the number of broadcasts reaches the broadcast number threshold. The preset time and the broadcast number threshold can be pre-set according to the experience of those skilled in the art, and the embodiments of the present invention do not specifically limit them.

[0049] It can be understood that when no response information is received from the responding host within the preset time, the file transfer information of the file to be stored is re-broadcast to the candidate hosts in the target LAN, which increases the probability that the candidate hosts in the target LAN receive the file transfer information, thereby increasing the number of responding hosts and effectively avoiding the waste of time and resources caused by continuously waiting for the candidate hosts in the target LAN to respond.

[0050] Optionally, the number of responding hosts can also be counted. If the number of responding hosts is equal to or greater than the host number threshold, then based on the response information sent by the received responding hosts, an available host that meets the file storage capacity is determined from at least one responding host; if the number of responding hosts is less than the host number threshold, the file transfer information of the file to be stored is rebroadcasted to the candidate hosts in the target local area network until the number of responding hosts reaches the host number threshold, or the number of broadcasts reaches the broadcast number threshold. The host number threshold can be preset according to the experience of those skilled in the art, and the embodiment of the present invention does not specifically limit it.

[0051] It is understandable that, when the number of responding hosts is less than the host number threshold, the file transfer information of the to-be-stored files is rebroadcasted to the candidate hosts in the target local area network to increase the number of responding hosts, so as to facilitate the subsequent screening of the most suitable target host from at least one responding host. At the same time, when the number of responding hosts has not yet reached the host number threshold, but the number of broadcasts has reached the broadcast number threshold, the file transfer information of the to-be-stored files is stopped from being broadcasted to the candidate hosts in the target local area network, effectively avoiding excessive consumption and waste of network resources.

[0052] S104: When there are multiple available hosts, determine a target host from the multiple available hosts according to the file transfer time threshold, the file storage capacity, and the available host information corresponding to each available host, and store the file to be stored in the target host.

[0053] The file transfer time threshold can be preset according to actual business needs or the experience of those skilled in the art, and the embodiment of the present invention does not specifically limit it. Available host information refers to relevant information of available hosts; optionally, the available host information includes the host file transfer speed, host disk storage speed, and host disk remaining capacity of the available host. The host disk storage speed can be determined based on the disk storage speed of each disk in the available host. For example, the host disk storage speed can be equal to the average disk storage speed of each disk in the available host. For another example, the host disk storage speed can be equal to the minimum value of the disk storage speed of each disk in the available host.

[0054] Specifically, when there are multiple available hosts, the minimum file transfer speed of the available hosts is determined based on the host file transfer speed and the host disk storage speed of the available hosts; the file transfer time of the available hosts is determined based on the file storage capacity and the minimum file transfer speed; the intermediate hosts are screened out from the multiple available hosts based on the file transfer time threshold and the file transfer time of each available host; when there are multiple intermediate hosts, the target hosts are screened out from the multiple intermediate hosts based on the remaining capacity of the host disk of each intermediate host, and the files to be stored are stored in the target hosts. Among them, the minimum file transfer speed refers to the minimum file transfer speed of the available hosts. The intermediate host refers to the host generated in the process of determining the target host. The file transfer time refers to the time required for the available host to complete the storage of the files to be stored.

[0055] Specifically, when there are multiple available hosts, for each available host, the host file transfer speed of the available host is compared with the host disk storage speed of the available host, and the smaller speed between the host file transfer speed and the host disk storage speed is used as the minimum file transfer speed of the available host; then, the time obtained by dividing the file storage capacity by the minimum file transfer speed of the available host is used as the file transfer time of the available host, so as to obtain the file transfer time of each available host. Then, according to the file transfer time threshold and the file transfer time of each available host, the available hosts whose file transfer time is less than or equal to the file transfer time threshold are selected from the multiple available hosts as intermediate hosts; when there are multiple intermediate hosts, the intermediate host with the smallest remaining host disk capacity is selected as the target host; and the files to be stored are stored in the target host.

[0056] Exemplarily, if the file transfer time threshold is 1 second (i.e. 1s), the file storage capacity is 100MB, and there are three available hosts, namely available host A, available host B and available host C; wherein, the host file transfer speed of available host A is 100MB / s, the host disk storage speed is 80MB / s, and the remaining capacity of the host disk is 10GB; the host file transfer speed of available host B is 100MB / s, the host disk storage speed is 100MB / s, and the remaining capacity of the host disk is 40GB; the host file transfer speed of available host C is 100MB / s, the host disk storage speed is 500MB / s, and the remaining capacity of the host disk is 20GB. For available host A, the host file transfer speed of available host A is compared with the host disk storage speed of available host A, and the smaller speed of the host file transfer speed and the host disk storage speed is used as the minimum file transfer speed of available host A, that is, the minimum file transfer speed of available host A is 80MB / s; similarly, the minimum file transfer speed of available host B is 100MB / s, and the minimum file transfer speed of available host C is 100MB / s; then, the time obtained by dividing the file storage capacity (i.e. 100MB) by the minimum file transfer speed of available host A (i.e. 80MB / s) is used as the file transfer time of available host A, that is, the file transfer time of available host A is ; Similarly, it can be obtained that the file transfer time of available host B is 1s, and the file transfer time of available host C is 1s. Afterwards, according to the file transfer time threshold (i.e. 1s) and the file transfer time of each available host, available hosts with file transfer time less than or equal to the file transfer time threshold are selected from available host A, available host B and available host C as intermediate hosts, i.e., the intermediate hosts include available host B and available host C; the intermediate host with the smallest remaining host disk capacity is selected as the target host, i.e., the target host is available host C; and the file to be stored is stored in available host C.

[0057] For example, if the file transfer time threshold is 1s, the file storage capacity is 50MB, and the available hosts are still available host A, available host B, and available host C, then the minimum file transfer speed of available host A is 80MB / s, the minimum file transfer speed of available host B is 100MB / s, and the minimum file transfer speed of available host C is 100MB / s. Then, the time obtained by dividing the file storage capacity (i.e., 50MB) by the minimum file transfer speed of available host A (i.e., 80MB / s) is used as the file transfer time of available host A, that is, the file transfer time of available host A is ; Similarly, it can be obtained that the file transfer time of available host B is 0.5s, and the file transfer time of available host C is 0.5s. Afterwards, according to the file transfer time threshold (i.e. 1s) and the file transfer time of each available host, available hosts with file transfer time less than or equal to the file transfer time threshold are selected from available host A, available host B and available host C as intermediate hosts, i.e., the intermediate hosts include available host A, available host B and available host C; the intermediate host with the smallest remaining host disk capacity is selected as the target host, i.e., the target host is available host A; and the file to be stored is stored in available host A.

[0058] It can be understood that, in the case where there are multiple available hosts, based on the file transfer time threshold, file storage capacity, and the host file transfer speed corresponding to each available host, the host disk storage speed, and the remaining capacity of the host disk, the available hosts whose file transfer time meets the file transfer time threshold and can make better use of storage resources are screened from the multiple available hosts as target hosts. In the case where the remaining host disk capacity of each available host meets the file storage capacity, an intermediate host with a smaller remaining host disk capacity is selected from the intermediate hosts whose file transfer time meets the file transfer time threshold for storage, thereby more effectively utilizing the existing storage resources and reducing the waste of storage space.

[0059] Optionally, when no intermediate host exists, the target host is determined from multiple available hosts according to the minimum file transfer speed of each available host and the remaining capacity of the host disk.

[0060] Specifically, when there is no intermediate host, that is, when there is no available host whose file transfer time is less than or equal to the file transfer time threshold among the available hosts, the minimum file transfer speeds of the available hosts are sorted from high to low to obtain the candidate host with the highest minimum file transfer speed; if there is one candidate host, the candidate host is used as the target host; if there are multiple candidate hosts, the candidate host with the smallest remaining host disk capacity is selected from the multiple candidate hosts as the target host. The candidate host refers to a host among the available hosts that may become the target host.

[0061] For example, if the file transfer time threshold is 1s, the file storage capacity is 1000MB, and the available hosts are still available host A, available host B, and available host C. If it is known that the minimum file transfer speed of available host A is 80MB / s, the minimum file transfer speed of available host B is 100MB / s, and the minimum file transfer speed of available host C is 100MB / s, according to the file storage capacity (i.e., 1000MB) and the minimum file transfer speed of each available host, it can be obtained that the file transfer time of available host A is 12.5s, the file transfer time of available host B is 10s, and the file transfer time of available host C is 10s. It can be seen that there is no available host with a file transfer time less than or equal to the file transfer time threshold (i.e., 1s) among available host A, available host B, and available host C, that is, there is no intermediate host. In this case, the minimum file transfer speeds of the available hosts are sorted from high to low to obtain the candidate hosts with the highest minimum file transfer speed, that is, the candidate hosts include available host B and available host C; then, the candidate host with the smallest remaining host disk capacity is selected from available host B and available host C as the target host, that is, the target host is available host C.

[0062] It is understandable that when all available hosts are unable to complete the storage of the files to be stored within the file transfer time threshold, the available host with the highest minimum file transfer speed and the smallest remaining host disk capacity is selected as the target host. This not only achieves fast storage of the files to be stored, but also optimizes the use of storage resources, reduces the need for additional storage devices, reduces unnecessary expansion operations, and thus reduces file storage costs.

[0063] Optionally, when the number of available hosts is one, the file to be stored is directly stored in the available host.

[0064] Optionally, after the file to be stored is stored in the target host, a soft link of the file to be stored can be established in the original host, that is, the IP address of the storage host of the file to be stored, the actual file storage path and the original file storage path are recorded in the original host, so as to refer to and trace the file to be stored later. The actual file storage path refers to the actual storage path of the file to be stored.

[0065] The technical solution of the embodiment of the present invention is as follows: after a monitoring interface monitors a file saving event, relevant file information corresponding to the file saving event is obtained; wherein the relevant file information includes the file to be stored, the file storage capacity, the file storage disk, and the original host to which the file storage disk belongs; when it is detected that the remaining disk capacity of the file storage disk does not meet the file storage capacity, and the remaining disk capacity of the candidate disks in the original host does not meet the file storage capacity, the target local area network where the original host is located is determined, and the file transfer information of the file to be stored is broadcast to the candidate hosts in the target local area network; wherein the candidate disk refers to the disk other than the file storage disk in the original host; the candidate host refers to the host other than the original host in the target local area network; according to the response information sent by the received responding host, an available host that meets the file storage capacity is determined from at least one responding host; when there are multiple available hosts, according to the file transfer time threshold, the file storage capacity and the available host information corresponding to each available host, the target host is determined from the multiple available hosts, and the file to be stored is stored in the target host. The above technical solution, when it is detected that the remaining disk capacity of the file storage disk does not meet the file storage capacity, and the remaining disk capacity of the candidate disks in the original host does not meet the file storage capacity, will transfer the file to be stored to other hosts in the target LAN where the original host is located, thereby realizing the storage of files between different hosts in the same LAN, without the need to purchase additional large-capacity hard disks or dedicated storage hardware, and without the need to expand the disk of the original host, thereby reducing the downtime and data migration costs related to expansion, and further reducing file storage costs.

[0066] On the basis of the above embodiment, as an optional method of the embodiment of the present invention, when it is detected that the remaining disk capacity of the file storage disk meets the file storage capacity, that is, when it is detected that the remaining disk capacity of the file storage disk is greater than or equal to the file storage capacity, the file to be stored is directly stored in the file storage disk.

[0067] Embodiment 2

[0068] Figure 2AThis is a flowchart of a file storage method provided in the second embodiment of the present invention. Based on the above embodiment, this embodiment provides an optional implementation scheme for storing the to-be-stored file when it is detected that the remaining capacity of the file storage disk does not meet the file storage capacity, and there is a candidate disk in the original host whose remaining capacity meets the file storage capacity. It should be noted that for the parts not described in detail in the embodiment of the present invention, reference can be made to the relevant descriptions of other embodiments. Figure 2A As shown, the method includes:

[0069] S201. After the monitoring interface monitors a file saving event, obtain relevant file information corresponding to the file saving event; wherein the relevant file information includes the file to be stored, the file storage capacity, the file storage disk, and the original host to which the file storage disk belongs.

[0070] S202: When it is detected that the remaining capacity of the file storage disk does not meet the file storage capacity, and there are candidate disks meeting the file storage capacity in the original host, count the number of candidate disks meeting the file storage capacity in the original host.

[0071] The number of candidate disks refers to the total number of candidate disks in the original host whose remaining disk capacity is greater than or equal to the file storage capacity.

[0072] Specifically, when it is detected that the remaining disk capacity of the file storage disk is less than the file storage capacity, and there are candidate disks in the original host whose remaining disk capacity is greater than or equal to the file storage capacity, the number of candidate disks in the original host that meet the file storage capacity is counted through a specially set counter.

[0073] Optionally, after counting the number of candidate disks that meet the file storage capacity in the original host, if the number of candidate disks is one, the file to be stored is directly stored in this candidate disk that meets the file storage capacity, and a soft connection for the file to be stored is established in the original host, that is, the IP address of the storage host of the file to be stored, the actual file saving path and the original file saving path are recorded in the original host, so as to facilitate subsequent reference and tracing of the file to be stored.

[0074] S203: When there are multiple candidate disks, determine the file storage time of each candidate disk according to the file storage capacity and the disk storage speed of each candidate disk.

[0075] The file storage time refers to the time required for the candidate disk to complete the storage of the file to be stored. It should be noted that the candidate disk mentioned here refers to the candidate disk in the original host that meets the file storage capacity.

[0076] Specifically, when there are multiple candidate disks, for each candidate disk in the original host that meets the file storage capacity, the time obtained by dividing the file storage capacity by the disk storage speed of the candidate disk is used as the file storage time of the candidate disk.

[0077] For example, if the file storage capacity is 50MB, there are three candidate disks, that is, there are three candidate disks in the original host that meet the file storage capacity, namely candidate disk 1, candidate disk 2 and candidate disk 3; wherein, the disk storage speed of candidate disk 1 is 80MB / s, and the remaining disk capacity is 10GB; the disk storage speed of candidate disk 2 is 100MB / s, and the remaining disk capacity is 40GB; the disk storage speed of candidate disk 3 is 500MB / s, and the remaining disk capacity is 20GB. For candidate disk 1, the time obtained by dividing the file storage capacity (i.e., 50MB) by the disk storage speed of candidate disk 1 (i.e., 80MB / s) is used as the file storage time of candidate disk 1, that is, the file storage time of candidate disk 1 is 0.625s. Similarly, it can be obtained that the file storage time of candidate disk 2 is 0.5s, and the file storage time of candidate disk 3 is 0.1s.

[0078] For example, the file storage capacity is 100MB, and the candidate disks that meet the file storage capacity in the original host are still candidate disk 1, candidate disk 2, and candidate disk 3; for candidate disk 1, the time obtained by dividing the file storage capacity (i.e., 100MB) by the disk storage speed of candidate disk 1 (i.e., 80MB / s) is used as the file storage time of candidate disk 1, that is, the file storage time of candidate disk 1 is 1.25s. Similarly, it can be obtained that the file storage time of candidate disk 2 is 1s, and the file storage time of candidate disk 3 is 0.2s.

[0079] S204: Filter out an intermediate disk from multiple candidate disks according to a file storage time threshold and the file storage time of each candidate disk.

[0080] The file storage time threshold can be preset according to actual business requirements or the experience of those skilled in the art, and the embodiment of the present invention does not specifically limit it. The intermediate disk refers to a disk generated in the process of determining the target disk. It should be noted that the candidate disk mentioned here refers to a candidate disk in the original host that meets the file storage capacity.

[0081] Specifically, according to the file storage time threshold and the file storage time of each candidate disk, a candidate disk whose file storage time is less than or equal to the file storage time threshold is screened out from multiple candidate disks that meet the file storage capacity as the intermediate disk.

[0082] For example, if the file storage time threshold is 1 second (i.e., 1s), the file storage capacity is 50MB, and the candidate disks that meet the file storage capacity in the original host are still candidate disk 1, candidate disk 2, and candidate disk 3, then it can be obtained that the file storage time of candidate disk 1 is 0.625s, the file storage time of candidate disk 2 is 0.5s, and the file storage time of candidate disk 3 is 0.1s. Afterwards, according to the file storage time threshold and the file storage time of each candidate disk, the candidate disks whose file storage time is less than or equal to the file storage time threshold are screened out from candidate disk 1, candidate disk 2, and candidate disk 3 as intermediate disks, that is, the intermediate disks include candidate disk 1, candidate disk 2, and candidate disk 3.

[0083] For example, if the file storage time threshold is 1s, the file storage capacity is 100MB, and the candidate disks that meet the file storage capacity in the original host are still candidate disk 1, candidate disk 2, and candidate disk 3, then it can be obtained that the file storage time of candidate disk 1 is 1.25s, the file storage time of candidate disk 2 is 1s, and the file storage time of candidate disk 3 is 0.2s. Afterwards, according to the file storage time threshold and the file storage time of each candidate disk, the candidate disks whose file storage time is less than or equal to the file storage time threshold are screened out from candidate disk 1, candidate disk 2, and candidate disk 3 as intermediate disks, that is, the intermediate disks include candidate disk 2 and candidate disk 3.

[0084] It can be understood that when there are multiple candidate disks that meet the file storage capacity in the original host, by determining the file storage time of each candidate disk, a candidate disk whose file storage time is less than or equal to the file storage time threshold is screened out from the multiple candidate disks that meet the file storage capacity and used as an intermediate disk, which helps to achieve fast storage of the files to be stored.

[0085] S205: In the case that there are multiple intermediate disks, a target disk is selected from the multiple intermediate disks according to the remaining capacity of each intermediate disk, and the file to be stored is stored in the target disk.

[0086] The target disk refers to the disk that is ultimately used to store the files to be stored.

[0087] Specifically, when there are multiple intermediate disks, an intermediate disk with the smallest remaining capacity is selected from the multiple intermediate disks as the target disk, and the file to be stored is stored in the target disk.

[0088] Optionally, when no intermediate disk exists, the target disk is determined from multiple candidate disks according to the disk storage speed and remaining disk capacity of each candidate disk.

[0089] Specifically, when the intermediate disk does not exist, that is, when there is no candidate disk whose file storage time is less than or equal to the file storage time threshold among multiple candidate disks that meet the file storage capacity, the disk storage speed of each candidate disk is sorted from high to low to obtain the candidate disk with the highest disk storage speed; if the number of candidate disks is one, the candidate disk is used as the target disk; if the number of candidate disks is multiple, the candidate disk with the smallest remaining disk capacity is selected from the multiple candidate disks as the target disk. Among them, the candidate disk refers to a disk among the candidate disks that may become the target disk. It should be noted that the candidate disk mentioned here refers to the candidate disk that meets the file storage capacity in the original host.

[0090] For example, if the file transfer time threshold is 1s, the file storage capacity is 1000MB, and the candidate disks that meet the file storage capacity in the original host are still candidate disk 1, candidate disk 2, and candidate disk 3, then it can be obtained that the file storage time of candidate disk 1 is 12.5s, the file storage time of candidate disk 2 is 10s, and the file storage time of candidate disk 3 is 2s. Therefore, it can be seen that there is no candidate disk whose file storage time is less than or equal to the file storage time threshold among candidate disk 1, candidate disk 2, and candidate disk 3, that is, there is no intermediate disk. In this case, the disk storage speeds of candidate disk 1, candidate disk 2, and candidate disk 3 are sorted from high to low, and the candidate disk with the highest disk storage speed is obtained, that is, the candidate disk is candidate disk 3; then, candidate disk 3 is used as the target disk.

[0091] It can be understood that when all candidate disks that meet the file storage capacity in the original host are unable to complete the storage of the file to be stored within the file storage time threshold, the candidate disk with the highest disk storage speed is selected as the target disk, thereby achieving rapid storage of the file to be stored; when there are multiple candidate disks with the highest disk storage speed, the candidate disk with the smallest remaining disk capacity is further selected as the target disk, thereby achieving optimal utilization of storage resources in the original host and facilitating storage of the file to be stored in the most suitable location in the original host.

[0092] Optionally, when the number of the intermediate disk is one, the file to be stored is directly stored in the intermediate disk.

[0093] Optionally, after storing the file to be stored in the target disk, a soft link of the file to be stored can be established in the original host, that is, the IP address of the storage host of the file to be stored, the actual file saving path and the original file saving path are recorded in the original host, so as to refer to and trace the file to be stored later.

[0094] The technical solution of the embodiment of the present invention is to obtain relevant file information corresponding to the file saving event after the listening interface listens to the file saving event; wherein the relevant file information includes the file to be stored, the file storage capacity, the file storage disk, and the original host to which the file storage disk belongs; when it is detected that the remaining disk capacity of the file storage disk does not meet the file storage capacity, and there are candidate disks that meet the file storage capacity in the original host, the number of candidate disks that meet the file storage capacity in the original host is counted; when there are multiple candidate disks, the file storage time of each candidate disk is determined according to the file storage capacity and the disk storage speed of each candidate disk; according to the file storage time threshold and the file storage time of each candidate disk, an intermediate disk is screened out from the multiple candidate disks; when there are multiple intermediate disks, a target disk is screened out from the multiple intermediate disks according to the remaining disk capacity of each intermediate disk, and the file to be stored is stored in the target disk. The above technical solution, when it is detected that the remaining capacity of the file storage disk does not meet the file storage capacity, and there is a candidate disk that meets the file storage capacity in the original host, transfers the file to be stored to other disks in the original host except the file storage disk, thereby realizing the storage of files between different disks of the same host, without the need to purchase additional large-capacity hard disks or dedicated storage hardware, and without the need to expand the capacity of the original host's disk, thereby reducing the downtime and data migration costs related to capacity expansion, and further reducing file storage costs.

[0095] Based on the above embodiment, a preferred file storage method is provided. Figure 2B , the method comprising:

[0096] S1. After the monitoring interface monitors a file saving event, obtain relevant file information corresponding to the file saving event; wherein the relevant file information includes the file to be stored, the file storage capacity, the file storage disk, and the original host to which the file storage disk belongs.

[0097] It should be noted that after executing S1, when it is detected that the remaining disk capacity of the file storage disk meets the file storage capacity, the file to be stored is directly stored in the file storage disk; when it is detected that the remaining disk capacity of the file storage disk does not meet the file storage capacity, and the remaining disk capacity of the candidate disks in the original host does not meet the file storage capacity, S2, S3 and S4 are executed sequentially; when it is detected that the remaining disk capacity of the file storage disk does not meet the file storage capacity, and there are candidate disks that meet the file storage capacity in the original host, S5, S6, S7 and S8 are executed sequentially.

[0098] S2. Determine the target local area network where the original host is located, and broadcast the file transfer information of the file to be stored to the candidate hosts in the target local area network.

[0099] S3. Determine an available host that meets the file storage capacity from at least one responding host according to the received response information sent by the responding host.

[0100] It should be noted that if the number of available hosts is one, the file to be stored is directly stored in the available host.

[0101] S4. When there are multiple available hosts, determine a target host from the multiple available hosts according to the file transfer time threshold, the file storage capacity, and the available host information corresponding to each available host, and store the file to be stored in the target host.

[0102] Optionally, storing the file to be stored in the target host can be: obtaining the remaining disk capacity of each disk in the target host, and taking the disk whose remaining disk capacity is greater than or equal to the file storage capacity as the available disk; if there is only one available disk, directly storing the file to be stored in the available disk of the target host; if there are multiple available disks, sorting the disk storage speeds of the available disks in the target host from high to low, and selecting the available disk with the highest disk storage speed from the available disks as the target disk; if there is only one target disk, directly storing the file to be stored in the target disk; if there are multiple target disks, storing the file to be stored in the target disk with the smallest remaining disk capacity.

[0103] S5. Count the number of candidate disks in the original host that meet the file storage capacity.

[0104] It should be noted that if the number of candidate disks is one, the file to be stored is directly stored in the candidate disk that meets the file storage capacity.

[0105] S6. When there are multiple candidate disks, determine the file storage time of each candidate disk according to the file storage capacity and the disk storage speed of each candidate disk.

[0106] S7. Filter out an intermediate disk from multiple candidate disks according to a file storage time threshold and the file storage time of each candidate disk.

[0107] It should be noted that if there is only one intermediate disk, the file to be stored is directly stored in the intermediate disk; if the intermediate disk does not exist, the target disk is determined from multiple candidate disks based on the disk storage speed and remaining disk capacity of each candidate disk.

[0108] S8. In the case that there are multiple intermediate disks, a target disk is selected from the multiple intermediate disks according to the remaining capacity of each intermediate disk, and the file to be stored is stored in the target disk.

[0109] The technical solution of the embodiment of the present invention, when it is detected that the remaining disk capacity of the file storage disk does not meet the file storage capacity, and the remaining disk capacity of the candidate disks in the original host does not meet the file storage capacity, the file to be stored is transferred to other hosts in the target local area network where the original host is located, thereby realizing the storage of files between different hosts in the same local area network; when it is detected that the remaining disk capacity of the file storage disk does not meet the file storage capacity, and there are candidate disks that meet the file storage capacity in the original host, the file to be stored is transferred to other disks in the original host except the file storage disk, thereby realizing the storage of files between different disks of the same host. During the entire file storage process, there is no need to purchase additional large-capacity hard disks or dedicated storage hardware, nor is there any need to expand the disk of the original host, thereby reducing the downtime and data migration costs related to expansion, and further reducing the file storage cost.
