Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0014] Realizing the smooth upgrade of network storage capacity and retaining the original storage device and the data stored in it is the main problem to be solved by the present invention. The general idea is: introduce virtual file system technology and deploy virtual file system on the workstation System software (hereinafter referred to as VFS), this software is responsible for virtualizing the hard disk drive on the workstation. The application system can create, modify, and delete files on the virtualized device just like accessing ordinary storage devices. VFS is responsible for these operations on the upper layer. Transferring to the actual storage device, if you want to dynamically expand the capacity, you only need to make VFS think that the newly added device is also responsible for the data storage of a previous virtual drive.

Abstract

The invention relates to a method used for dynamically expanding the network memory space by a virtual file system technique, belonging to the field of network data memory technique; the method comprises the steps as follows: virtual file system software is arranged on the workstation of an application system; the software simulates a hard disk driver on the workstation and achieves the data transfer; data connection is established between the virtual hard disk driver and a memory control server; a plurality of network disks are bound together by the virtual driver. The method achieves the smooth upgrade of the network memory capacity, remains the existing memory equipment and the data memorized in the memory equipment, and can achieve the extension of dynamic capacity without breaking the current operations.

Description

technical field [0001] The invention belongs to the technical field of network data storage, and in particular relates to a method for dynamically expanding network storage space by utilizing virtual file system technology. The method can be applied to various network data storage fields in IT-related industries, and can expand network storage capacity without reducing storage performance or modifying application software configuration. Background technique [0002] With the rapid development of informatization, the demand for data storage in various industries is increasing, and the growth of these demands is mainly reflected in the growth of data volume. Generally speaking, the expansion of network storage will have a certain impact on the upper-layer application system, especially when the application system does not consider the need for expansion, the impact will be even greater, and even lead to a complete upgrade of the entire system, resulting in the original Waste ...
