Abstract

The invention discloses a distributed block device driving method and system for cloud storage. The method comprises the steps that an I/O request transmitted from an upper-layer file system is converted into an access message of a virtual block device, a network card drive is called to send a data packet to a server, and therefore a true physical storage device on the server can be accessed. According to the distributed block device driving method and system, remote loading and running of various operating systems and instruction interfaces of various storage devices can be supported, and data requesting and processing can be efficiently finished.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a distributed block device driving method and system for cloud storage. Background technique [0002] With the development of network technology, users synchronize important personal data to network storage devices through terminal devices for storage and management. As a new type of network computing model, cloud computing provides users with familiar operating systems and applications as network storage content. The cloud computing terminal remotely loads the operating system through the network, adopts the block flow method to execute dynamically, and provides users with various cross-platform applications and services. Since the cloud computing terminal itself does not preset a physical storage device, it needs to use a virtual storage device driver to interact with the physical storage resources on the cloud computing server, so as to provide the user with a virtual disk view...
