Local storage capacity expansion system based on device driver

Abstract

The invention discloses a local storage capacity expansion system based on an equipment driving program. Three different types of terminals interact with a server. Data transmission is carried out between all terminals and the server. The terminals comprise a first type terminal, a second type terminal and a third type terminal. Operating systems in the first-type terminal and the second-type terminal are divided into a user space and a kernel space. The type I terminal interacts with the server through a driving program in a kernel space; wherein the type 2 terminal interacts with the serverthrough a terminal network communication library in a user space, and the type 3 terminal comprises an embedded application program and a function library and interacts with the server through cooperation of the embedded application program and the function library. Program sets contained in the three types of terminals create a plurality of local storage devices for a user or create a plurality of storage devices through a soft bus, a virtual bus interface, a virtual bus device and a virtual storage device technology so as to achieve expansion of the local storage capacity.

Description

technical field [0001] The invention relates to a storage capacity expansion system, in particular to a device driver-based local storage capacity expansion system. Background technique [0002] With the development of information technology, a large amount of information has been digitized and transformed into computer-recognizable data, which is processed by the existing computer system, which puts forward new requirements for the existing computer storage system, and requires the computer system to have flexible data storage capacity. Most of the existing computer system storage quotas have been calibrated before the business system goes online. When the storage capacity is expanded later, the system usually needs to be shut down, which is difficult to meet the non-stop and flexible dynamic expansion requirements of modern applications. In smart devices, users may have insufficient storage capacity due to taking a large number of photos and videos. However, modern smart ...

Problems solved by technology

There are many limitations in this implementation method. First of all, it is troublesome to use. Users must manually upload their data to the cloud or download data from the cloud through the client software, which cannot be transparent and localized; and then The user experience is not good. Every file stored in the cloud must be completely downloaded to the local through the client software before each use. Such a waiting process greatly affects the user experience; The disk cannot be dynamically, customized, and fine-grained to adjust the cloud resource configuration according to the user's resource usage. Generally, the user's storage expansion is performed at the GB level or above.

[0005] In the field of enterprise storage, traditional network storage technologies include network file system (NFS) implemented at the file system level, iSCSI at the disk level, network block device (NBD) and other technologies. It is not suitable for the complex and changeable mobile network environment, nor can it meet the dynamic, customized and mobile requirements of various intelligent terminals and embedded devices for storage devices at the present stage.
