File access method used for management system

Abstract

The invention relates to a file access method used for a management system which comprises a management end device, a managed end device and a system management device. The file access method comprises: simulating an entity storage device of the management end device into the managed end device through the system management device so as to form a virtual storage device in the managed end device; outputting a request command to the system management device through an operating system of the managed end device without a file system of the management device when the managed end device stores a file of the virtual storage device; and performing the storage of the file to the entity storage device by the managed end device through an operating system of the management end device without a filesystem of the management end device according to the request command.

Description

technical field [0001] The invention relates to a file access method used in a management system, in particular to a file access method which can avoid file asynchrony, prevent data damage, and maintain normal operation of the system. Background technique [0002] In order to effectively provide remote management services, the prior art provides a server using a system management device (System Management Device), so that managers can maintain or monitor servers in the computer room through the network anytime and anywhere. Generally speaking, the system management device usually provides KVM-over-IP, virtual storage (Virtual Storage, or Drive Redirection, VirtualMedia) and other functions. [0003] In the KVM-over-IP function, KVM is the abbreviation of the three prefixes Keyboard, Video, and Mouse, which means that 2 to 4032 computers are controlled by a set of keyboards, monitors, and mice. General KVM can only be operated by administrators on site, but if the KVM host c...

Problems solved by technology

In other words, when the managed device 102 writes a file to the virtual storage device 108, the file system of the management device 100 cannot know the file update situation of the physical storage device 106, causing the management device 100 and the managed device 102 The problem of out-of-sync files between

In this case, when other application programs of the management terminal device 100 access the files of the physical storage device 106 through a path b4, data damage may occur, resulting in a system error

[0008] Therefore, in order to avoid the above problems, the prior art usually restricts the user of the management terminal device 100 from accessing the files of the physical storage device 106

In other words, the management terminal device 100 and the managed terminal device 102 cannot achieve two-way access to the files of the physical storage device 106, thus causing its scope of application to be limited.
