Problems solved by technology

However, the hardware method does not support online expansion. Every time expansion, you must first shut down. In addition, the number of hard disks that RAID can support is limited, that is, the maximum capacity that can be supported is limited.

Embodiment Construction

[0020] The technical solution of the present invention will be described in detail below.

[0021] The method for unlimited online expansion of storage space includes: providing a storage virtualization manager, the storage virtualization manager virtualizes at least one storage space accessible by a server into a unique virtual storage space, and converts the unique virtual storage space The storage space is displayed to the user in the form of a directory, so the user does not need to care about how many storage spaces there are and which storage space the file is stored on. For the user, there is only one storage space. The remaining capacity of one storage space is the sum of the remaining capacities of all storage spaces. The user only needs to access the server in a normal way and perform a series of operations such as creating a new directory, creating a new file, deleting a directory, and deleting a file. Preferably, the storage virtualization manager sets the director...

Abstract

The invention relates to a method for expanding storage space on line, which comprises a step of providing a storage virtualization manager which can virtualize many storage spaces accessed by a server into a unique virtual storage space and display the unique virtual storage space to a user in a directory structure mode. The method is characterized in that the many storage spaces have the same directory structure. In the method, the online expansion of the storage space of the server can be realized by increasing the storage spaces the server can access at any time and avoiding turning off the service in advance at each time of capacity expansion, and as the number and size of the online storage spaces the server can access are not limited, endless capacity expansion can be realized.

Description

technical field [0001] The invention relates to a method for expanding storage space online. Background technique [0002] Multiple hard disks are formed into a disk array through hardware methods such as RAID cards to achieve the purpose of combining the capacity of multiple hard disks into a large capacity. However, the hardware method does not support online expansion. Every time the capacity is expanded, the computer must be shut down first. In addition, the number of hard disks that RAID can support is limited, that is, the maximum capacity that can be supported is limited. Contents of the invention [0003] The purpose of the present invention is to provide a method for online expandable storage space that virtualizes all storage spaces accessible by the server into a unique storage space and displays it to users in the form of catalogue. [0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a method...
