Abstract

Disclosed is a virtual storage service system comprising: a web server configured to receive selection information including a virtual storage capacity necessary for a virtual storage service, the number of storage nodes, storage node types, a distribution method, and a selected storage node from the terminal when the terminal requests the virtual storage service; a control center server configured to exert control with reference to the selection information so that a virtual disk volume is generated; at least one storage node configured to generate the virtual disk volume according to the control of the control center server; and a database (DB) configured to store information of the storage nodes and virtual disk volume information of the user.

Claims

1. A virtual storage service system connected to at least one user terminal through a network, the system comprising:

a web server configured to receive selection information including a virtual storage capacity necessary for a virtual storage service, the number of storage nodes, storage node types, a distribution method, and a selected storage node from the terminal when the terminal requests the virtual storage service;

a control center server configured to exert control with reference to the selection information so that a virtual disk volume is generated;

at least one storage node configured to generate the virtual disk volume according to the control of the control center server; and

a database (DB) configured to store information of the storage nodes and virtual disk volume information of the user.

2. The virtual storage service system of claim 1, wherein, when the terminal requests the virtual storage service, the web server requests the terminal to input a necessary virtual storage capacity, storage node types to be generated, the number of storage nodes, and a distribution method,

when the virtual storage capacity, the storage node types, the number of storage nodes, and the distribution method are input from the terminal, the web server provides current storage node states to the terminal according to the virtual storage capacity, the storage node types, the number of storage nodes, and the distribution method, and

when the terminal selects the storage node to be used as a virtual storage in the node states, the web server requests the control center server to generate the virtual disk volume.

3. The virtual storage service system of claim 1, wherein the control center server controls the selected storage node to generate the virtual disk volume by the request of the web server, and

the selected storage node generates the virtual disk volume.

7. The virtual storage service system of claim 2, wherein the control center server controls the selected storage node to generate the virtual disk volume by the request of the web server, and

the selected storage node generates the virtual disk volume.

4. A virtual storage service method connected to at least one user terminal through a network, the method comprising:

requesting, by the terminal, a virtual storage service from a web server;

receiving, by the web server, selection information including a virtual storage capacity necessary for the virtual storage service, the number of storage nodes, storage node types, a distribution method, and a selected storage node from the terminal;

controlling, by a control center server, the selected storage node to generate a virtual disk volume with reference to the selection information; and

generating, by the selected storage node, the virtual disk volume according to the control of the control center server.

5. The virtual storage service method of claim 4, further comprising storing, by the control center server, information of the generated virtual disk volume of the user in a database (DB).

6. The virtual storage service method of claim 5, wherein the receiving of the selection information by the web server comprises:

when the terminal requests the virtual storage service, requesting the terminal to input a virtual storage capacity to be generated, storage node types, the number of storage nodes, and a distribution method;

when the virtual storage capacity to be generated, the storage node types, the number of storage nodes, and the distribution method are input from the terminal, providing current storage node states to the terminal according to the virtual storage capacity to be generated, the storage node types, the number of storage nodes, and the distribution method; and

when a storage node is selected in the current storage node states by the terminal, requesting the control center server to generate the virtual disk volume.
