The present application claims the priority to Chinese Patent Application No. 201810548589.7, titled “KVM, AND FOLDER ONE-KEY MOUNTING METHOD, DEVICE, APPARATUS AND MEDIUM APPLIED IN KVM”, filed on May 31, 2018 with the China National Intellectual Property Administration, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to the computer technology field, and in particular, to a KVM, a folder one-key mounting method, a folder one-key mounting device, a folder one-key mounting apparatus and a medium applied in the KVM.

BACKGROUND

KVM (K represents Keyboard, V represents Video, and M represents Mouse, KVM is also known as multi-computer switcher) technology aims to realize centralized management of systems and networks by configuring appropriately a keyboard, a mouse and a display, and to achieve effects of improving manageability of a system, increasing work efficiency of a system administrator, cutting an area of a computer room, lowering a cost of owning a network project and a server system, creating a healthy and environmental computer room by avoiding electromagnetic radiation from multiple displays, or the like. By utilizing the KVM, the system administrator may switch between multiple host computers or servers having different operating systems and manage the multiple host computers or servers with a keyboard, a mouse and a display. The servers may be controlled by the KVM remotely.

A function of mounting a folder is provided by the KVM for better utilizing various kinds of resources on a client. The function of mounting a folder is to mount a folder on a client to a server with the KVM. And the server may access the folder and any files in the folder just like accessing a local path. In the conventional technology, the function of mounting a folder with the KVM is realized by setting a size parameter and a path parameter manually by an operator, to designate a size for a temporary mirror image file generated subsequently and to designate a local path for a user to store the mirror image file. A temporary mirror image file with a designated size is generated in the local path of the client, and a target folder of the mirror image file is mounted to the server. That is, the size parameter and the path parameter should be set manually by the operator in the conventional technology, and thus it is inconvenient to operate for a user and may easily result in errors in operation, especially for a user who is not professional enough to know the specific meaning of the size parameter and the path parameter.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Following is a clear and complete description of the technical solutions of the present disclosure with reference to the accompanying drawings in the present disclosure. Apparently, the described embodiments are only some rather than all of the embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by the skilled in the art without any creative effort fall within the scope of the present disclosure.

During a process of mounting a folder with KVM in the conventional technology, it is necessary for an operator to designate a size for a temporary mirror image file to be generated and to designate a local path to store the mirror image file, which is inconvenient to operate for a user and may easily result in errors in operation. According to the present disclosure, a size and a storage path of the mirror image file are determined by a background program automatically instead of being inputted by the user manually, thereby simplifying the user operation, decreasing misoperation of the user, and improving the user experience.

A folder one-key mounting method applied in a KVM is provided according to an embodiment of the present disclosure. As shown in FIG. 1, the method includes the following steps S11 to S15.

In step S11, a size of a target folder is determined when a one-key mounting instruction for the target folder is obtained.

It should be noted that, the one-key mounting instruction in the embodiment may be generated in many ways. In an embodiment, the one-key mounting instruction may be triggered manually, for example, it may be triggered by a user through a preset instruction triggering button. It is understood that, before the instruction is triggered by the user, it is necessary for the user to select a folder to be mounted as the target folder with a preset folder selecting interface. In another embodiment, the one-key mounting instruction may be triggered automatically by a background system, for example, it may be triggered automatically when a preset timer in background has counted for a preset time duration. It is understood that, before the preset time duration of the timer is set, the target folder should be selected manually by the user or automatically by the background system. Other feasible ways of generating the one-key mounting instruction may also be used in the embodiment of the present disclosure, which are not listed herein for simplicity.

In the embodiment, the size of the target folder is determined after the one-key mounting instruction for the target folder is obtained. In an embodiment, the size of the target folder is determined by adding up the size of all files in the target folder. In another embodiment, an information table is preset, an identifier of every folder and a size of every folder are recorded in the information table. In a case that the one-key mounting instruction for the target folder is obtained, the size of the target folder is determined by search the information table for the size of the target folder. It is understood that, when a variation of a file in any folder occurs, a variation of a size of the folder due to the variation of the file should be determined in a real time manner, and the information table is updated based on the variation of the size of the folder. Other feasible ways of determining the size of the target folder may also be used in the embodiment of the present disclosure, which are not listed herein for simplicity.

In step S12, a size of a mirror image file is determined based on the size of the target folder.

It should be understood that, in the embodiment, the size of the mirror image file determined in step S12 should be not less than the size of the target folder. That is, taking the size of the target folder as a reference, a parameter having a value not less than the size of the target folder is determined as the size of the mirror image file.

In the embodiment, the size of the mirror image file determined in step S12 is a size of a mirror image file generated subsequently corresponding to the target folder.

In step S13, a storage path of the mirror image file is determined based on the size of the mirror image file.

It should be understood that, in the embodiment, the storage path determined in step S13 should be located in a disk having a remaining storage capacity greater than the size of the mirror image file. That is, a path located in a disk having a remaining storage capacity greater than the size of the mirror image file is determined as the storage path in step S13.

In the embodiment, a suitable path is selected as the storage path of the mirror image file from all paths based on the size of the mirror image file and information of the all paths. In order to improve the speed of determining the storage path, a specific path may be selected in advance as a preset path. When the size of the mirror image file is determined in step S12, it is determined whether a remaining storage capacity of a disk where the preset path is located is greater than the size of the mirror image file. And the preset path is determined as the storage path of the mirror image file if the remaining storage capacity of the disk where the preset path is located is greater than the size of the mirror image file.

It should be noted that, in the embodiment, generally, only one storage path of the mirror image file is determined based on the size of the mirror image file. In order to store the same mirror image file in positions corresponding to multiple different paths and mount the same mirror image file to multiple different servers, multiple storage paths of the mirror image file may be determined based on the size of the mirror image file in the embodiment. The number of the storage paths may be preset by the user or set by a background system automatically.

In step S14, a target mirror image file corresponding to the target folder and the size of the mirror image file is generated.

That is, the mirror image file corresponding to the target folder is generated in step S14. The size of the generated mirror image file is the same as the size of the mirror image file determined in step S12.

In step S15, the target mirror image file is stored in a position corresponding to the storage path, and the target mirror image file is mounted to a server.

It should be noted that, in a case that multiple storage paths of the mirror image file are determined based on the size of the mirror image file in step S13, step S15 includes: storing the target mirror image file in a position corresponding to each of the multiple storage paths, and mounting the target mirror image files stored in positions corresponding to the multiple storage paths to different servers respectively.

For example, in the embodiment, it is assumed that three storage paths of the mirror image file are determined based on the size of the mirror image file, then the target mirror image file is stored in positions corresponding to the three storage paths subsequently, and the target mirror image files stored in positions corresponding to the three storage paths are mounted to three different servers respectively. In this way, users of multiple servers may share the same mirror image file simultaneously.

It should be noted that, the KVM in the present disclosure may be operated in a Linux system. By utilizing a BMC (Baseboard Management Controller) in the Linux system, functions of the KVM may be accomplished.

It can be seen that, in the embodiment of the present disclosure, a size of a target folder is determined when a one-key mounting instruction for the target folder is obtained, a size of a mirror image file is determined based on the size of the target folder, a storage path of the mirror image file is determined based on the size of the mirror image file. It can be seen that, the size and the storage path of the mirror image file are determined by a background program automatically instead of being inputted by a user manually. In other words, in this application, it is avoided the operations in the conventional art of manually allocating the size and the storage path of the temporary mirror image file, which have high technical requirements and are complicated and error-prone, and are closely integrated with underlying technology. The operations of allocating the size and the storage path of the temporary mirror image file are automatically performed in the system, thereby greatly simplifying the user operation when the folder is mounted with KVM, decreasing misoperation of the user, and improving the user experience.

Reference is made to FIG. 2, which is a flow chart of a folder one-key mounting method according to an embodiment of the present disclosure. The method is applied to KVM, the method includes the following steps S21 to S26.

In step S21, when a one-key mounting instruction for the target folder is obtained, each file in the target folder is traversed to determine a size of each file, and the size of each file is accumulated to obtain the size of the target folder.

In the embodiment, every file in the target folder is traversed to determine the size of every file in the target folder. The size of the target folder is determined by summing up the size of every file in the target folder. GB (Gigabyte) is taken as a unit for measuring the size of the target folder.

Besides, other ways of determining the size of the target folder may also be applied, for example, the size of the target folder may be determined by searching a preset information table for the size of the target folder.

In step S22, a value of N is determined based on the size of the target folder with 2^NGB being greater than or equal to the size of the target folder, 2^NGB is determined as the size of the mirror image file, N is a non-negative integer.

In an embodiment, the determining a value of N based on the size of the target folder includes: determining the value of N to be 0 in a case that the size of the target folder is not greater than 1 GB; and determining the value of N to be a value meeting 2^N−1GB<S≤2^NGB in a case that the size of the target folder is greater than 1 GB, where S represents the size of the target folder. For example, if the size of the target folder is 2.6 GB, the value of N determined in the above manner is 2, and thus the size of the mirror image file is 4 GB.

In practice, the size of the target folder may be compared with 2^NGB. The value of N starts from 0 and is increased by one for each time, until 2^NGB is not less than the size of the target folder for the first time. 2^NGB, which is not less than the size of the target folder for the first time, is determined as the size of the mirror image file.

In another embodiment, in order to improve the speed of determining the size of the mirror image file, the determining a value of N based on the size of the target folder may include: presetting a non-negative integer N1 based on experiences; determining whether 2^N1GB is not less than the size of the target folder after the size of the target folder is determined in step S21; determining the non-negative integer N1 as the value of N in a case that 2^N1GB is not less than the size of the target folder. For example, if a size of a folder to be mounted is generally about 3 GB according to experiences, then N1 is preset to be 2. When the size of the target folder is determined, it is determined whether 2²GB is not less than the size of the target folder, that is, it is determined whether 4 GB is not less than the size of the target folder. 2 is determined as the value of N if 4 GB is not less than the size of the target folder.

In step S23, it is determined a remaining storage capacity of a disk where a preset path is located, and it is determined whether the remaining storage capacity of the disk where the preset path is located is greater than the size of the mirror image file.

In step S24, the preset path is determined as the storage path of the mirror image file, in a case that the remaining storage capacity of the disk where the preset path is located is greater than the size of the mirror image file. A path, located in a disk having a remaining storage capacity greater than the size of the mirror image file, is selected from paths other than the preset path as the storage path of the mirror image file, in a case that the remaining storage capacity of the disk where the preset path is located is not greater than the size of the mirror image file.

In the embodiment, in order to improve the speed of determining a storage path, a path is selected in advance to be a preset path. After the size of the mirror image file is determined, it is determined whether the remaining storage capacity of the disk where the preset path is located is greater than the size of the mirror image file. The preset path is determined as the storage path of the mirror image file, in a case that the remaining storage capacity of the disk where the preset path is located is greater than the size of the mirror image file. A suitable path is selected from paths other than the preset path as the storage path of the mirror image file, in a case that the remaining storage capacity of the disk where the preset path is located is not greater than the size of the mirror image file.

In the embodiment, the preset path is a home path of a current user.

In an embodiment, the selecting, from paths other than the preset path, a path located in a disk having a remaining storage capacity greater than the size of the mirror image file as the storage path of the mirror image file includes: selecting, by a user, from paths other than the preset path, a path located in a disk having a remaining storage capacity greater than the size of the mirror image file as the storage path of the mirror image file.

That is, if the remaining storage capacity of the disk where the preset path is located is not greater than the size of the mirror image file, the storage path of the mirror image file may be selected by the user. It should be understood that, before the storage path is selected by the user, a prompt dialog box may be popped up on a user interface, to prompt the user to input path selecting information through a preset input interface.

In another embodiment, the selecting, from paths other than the preset path, a path located in a disk having a remaining storage capacity greater than the size of the mirror image file as the storage path of the mirror image file includes: selecting, by a background program, a suitable path from paths other than the preset path as the storage path of the mirror image file based on the size of the mirror image file and information of each one of the paths other than the preset path, where the information of the path includes but is not limited to a secret level and a historical access frequency of the path.

In step S25, a target mirror image file corresponding to the target folder and the size of the mirror image file is generated.

In step S26, the target mirror image file is stored in a position corresponding to the storage path, and the target mirror image file is mounted to a server.

As shown in FIG. 3, a folder one-key mounting method applied in a KVM is provided in an embodiment of the present disclosure. The method includes the following steps S31 to S35.

In step S31, a preset information table is searched for the size of the target folder. The preset information table stores in advance an identifier of each folder and a size of each folder.

In the embodiment, in order to ensure a high time-effectiveness of the information table, the folder one-key mounting method may further include: monitoring a variation of a file in each folder in a real time manner; and when a variation of a file in a folder occurs, collecting variation information of the file and updating the information table based on the variation information of the file.

In step S32, a size of a mirror image file is determined based on the size of the target folder.

The detailed process of step S32 may be found in corresponding descriptions of the above embodiments, which will not be described again for simplicity.

In step S33, a path located in a disk having a remaining storage capacity greater than the size of the mirror image file is selected from all paths as the storage path of the mirror image file.

In a first implementation, since secret levels of different paths are different and levels of different servers are different, in order to avoid a path with a high secret level being browsed by a server with a low level, as shown in FIG. 4, the operation of selecting, from all paths, a path located in a disk having a remaining storage capacity greater than the size of the mirror image file as the storage path of the mirror image file may include steps S41 to S43.

In step S41, it is determined a secret level of each path and a remaining storage capacity of a disk where each path is located.

In step S42, a path located in a disk having a remaining storage capacity greater than the size of the mirror image file is selected from all paths to obtain a preliminary path set.

In step S43, a path having a secret level which is the same as a level of the server is selected from the preliminary path set as the storage path of the mirror image file.

It should be understood that, in the embodiment, one or more paths having a secret level which is the same as a level of the server may be selected from the preliminary path set as the storage path of the mirror image file, according to actual situations.

In a second implementation, since historical access frequencies of different paths are different, in order to avoid some paths being not accessed for a long time, in this embodiment, as shown in FIG. 5, the operation of selecting, from all paths, a path located in a disk having a remaining storage capacity greater than the size of the mirror image file as the storage path of the mirror image file may include steps S51 to S53.

In step S51, a historical access frequency of each path is determined and a remaining storage capacity of a disk where each path is located is determined.

In step S52, a path located in a disk having a remaining storage capacity greater than the size of the mirror image file is selected from all paths to obtain a preliminary path set.

In step S53, a path having a lowest historical access frequency is selected from the preliminary path set as the storage path of the mirror image file.

It should be understood that, in the embodiment, one or more paths having a lowest historical access frequency may be selected from the preliminary path set as the storage path of the mirror image file, according to actual situations.

In a third implementation, as shown in FIG. 6, the operation of selecting, from all paths, a path located in a disk having a remaining storage capacity greater than the size of the mirror image file as the storage path of the mirror image file may include steps S61 to S64.

In step S61, it is determined a secret level and a historical access frequency of each path and a remaining storage capacity of a disk where each path is located.

In step S62, a path located in a disk having a remaining storage capacity greater than the size of the mirror image file is selected from all paths, to obtain a first preliminary path set.

In step S63, a path having a secret level which is the same as a level of the server is selected from the first preliminary path set, to obtain a second preliminary path set.

In step S64, a path having a lowest historical access frequency is selected from the second preliminary path set as the storage path of the mirror image file.

It should be understood that, in the embodiment, one or more paths having a lowest historical access frequency may be selected from the second preliminary path set as the storage path of the mirror image file, according to actual situations.

In step S34, a target mirror image file corresponding to the target folder and the size of the mirror image file is generated.

In step S35, the target mirror image file is stored in a position corresponding to the storage path, and the target mirror image file is mounted to a server.
