FIG. 2 is a configuration diagram illustrating an example of a cloud-based disk and application sharing system in a data storage sharing system of WAN and LAN sections through IaaS according to an embodiment of the present invention. Side process of a cloud-based disk and application sharing system in a data storage sharing system of a WAN and a LAN section through IaaS according to the present invention.

As shown in FIGS. 2 and 3, a cloud type disk and application sharing system includes a server 100 and at least one client 200. Here, the server 100 may be a remote PC 20, and the client 200 may be a local PC 10.

The server 100 includes a Cloud Cast server module 110 and an Internet Virtual Partition (IVP) server module 120. The cloud cast server module 110 receives an image source drive to be designated as a cloud disk to be shared with the client 200 from the server manager. Here, the cloud disk refers to a disk of a server to be shared by a plurality of clients 200. More specifically, the cloud cast server module 110 further receives from the server manager a port to be used for communication with the client 200 and a data transmission packet size with the client. Then, an interrupt is generated to request the OS to transfer the disk management control right to the IVP server module 120.

In addition, the Internet Virtual Partition (IVP) server module 120 receives a mount request of the cloud disk from at least one client 200. Then, the file system of the server 100 including the cloud disk is copied, and the copied file system is transmitted to the requesting client 200. More specifically, the IVP server module 120 is loaded into the RAM by an operating system (OS) receiving an interrupt request from the cloud cast server module 110. Then, the IVP server module 120 receives the disk management control right from the operating system (OS) while being loaded into the RAM, and copies the file system of the server 100 including the cloud disk. In addition, the IVP server module 120 loads the replicated file system into the shadow memory.

Then, the IVP server module 120 monitors in real time whether the file system is changed by the OS 100 by the operating system (OS), and if there is a change in the file system, the IVP server module 120 reflects the changed file system in the replicated file system .

The IVP server module 120 receives a request for mounting a cloud disk from at least one client 200, and transmits the replicated file system to the requesting client 200. At this time, the IVP server module 120 in the server 100 preferably generates the copied file system by applying the image encryption technique.

Referring to FIG. 3, a server-side process according to an embodiment of the present invention will be described in more detail with reference to FIG. 3, which shows a source image source drive designated as a cloud disk to be shared with a client, a TCP port number used for communication with a client, Enter the size and press the Active button. In FIG. 3, it can be seen that the D: drive is designated as a cloud disk. Then, the cloud cast server module 110 generates an interrupt to the Windows OS to load the IVP server module 120 into the RAM, and passes the disk management control right to the IVP server module 120. The IVP server module is loaded into the RAM by the Windows operating system and copies the file system of the server including the drive designated as the cloud disk and loads it into the shadow memory.

In FIG. 3, the IVP server module 120 copies the FAT, which is the original file system of the server 100, and creates FAT 'to load it into the memory.

The IVP server module 120 monitors the disk management of the operating system in real time and immediately reflects the changes in the original file system FAT to the copy file system FAT ' The server can quickly respond to the changed information in the request.

Referring to FIG. 2 and FIG. 4, the client 200 includes a cloud cast client module 210. The cloudcast client module 210 receives the name of the drive and the mount request to mount the cloud disk from the user. And accesses the server 100 through an agent program to request the IVP server module 120 to mount the cloud disk.

In addition, it is preferable that the cloud cast client module 210 duplicate the original file system CFAT of the client 200 itself and load it in the memory.

The file system (SFAT ') replicated from the IVP server module 120 is received and loaded into the memory, and the drive name of the cloud disk of the transferred replicated file system (SFAT') is changed to a drive name to be mounted Create a virtual disk. Here, the virtual disk means a virtual partition space, and the virtual disk created by the client according to the present invention does not simply serve as a network drive, but operates in the same manner as the actual hard disk of the local system. However, And the image is a disk which is moved as an image file rather than an actual partition.

Then, a copy file system (CFAT ') of the client is created by including the virtual disk in the original file system of the client of the client.

Referring to FIG. 4, a virtual disk is created by changing the D: drive designated as a cloud disk in the server 100 to the Z: drive of the client 200 designated as the drive to be mounted, It can be seen that the drive is included in the original file system CFAT and a copy file system CFAT 'of the new client 200 is created. Therefore, the Z: drive of the client 200 is finally created by changing the name of the D: drive, which is the cloud disk of the server 100, and can recognize that the server 100 is a virtual disk to be mounted and shared by the cloud disk.

5, a client 200 having an actual C: drive executes a cloud cast client module 210 to map a D: drive, which is a cloud disk of the server 100, to a virtual disk Z: drive, , You can see that the virtual disk Z: drive appears to be an actual local drive.

In the meantime, the cloud cast client module 210 reflects the changed contents in the copy file system when the user changes the original file system, and when the user wants to access the file included in the virtual disk, the IVC server module It is desirable to request the file server 120 to provide the file and to receive the file from the IVP server module 120 to be executed.

In other words, referring to FIGS. 4 and 5, the cloud cast client module 210 will be described in more detail with respect to the cloud cast client module 210 on the client 200 side. The cloud cast client module 210 includes a drive name to mount the cloud disk, It receives input such as disk cache use, disk cache path, whether to mount automatically when booting the computer, and receives a mount request.

When the user inputs the use of the disk cache, the cloudcast client module 210 determines that the file exists in the disk cache file path when the user wants to access the file included in the virtual disk created by mounting the cloud disk .

If the file does not exist in the disk cache file path, the IVP server module 120 is requested to provide the file, the IVP server module 120 receives the file, stores the file in the disk cache, Is executed. The cloud cast client module 210 receives the mount request from the user and receives the copied file system of the server 100 from the IVP server module 120 of the server 100 to receive a copy file of the new client 200 System (CFAT ').

Then, the cloud cast client module 210 checks the changed contents of the original file system (CFAT) and reflects the changed contents in the copy file system (CFAT ') in real time. That is, if a user is working on a file contained in a source file system rather than a file contained in a virtual disk (Z: drive) on which the cloud disk is mounted, all data modifications, deletions, additions, (CFAT). In this case, the cloud cast client module 210 also reflects changes in the dms original file system (CFAT) to the copy file system (CFAT '). On the other hand, when the user accesses the file included in the virtual disk (Z: drive) and wants to work, the cloud cast client module 210 refers to the copy file system (CFAT ') to access the IVP server module 120, and the IVP server module 120 refers to the replicated file system (SFAT ') of the server and transmits the file to the client 200. [
