Remote on-hook switching method for U disk of KVM system
Technical Field
The present invention relates to the transmission of digital information, and more particularly to the control and processing of communication of digital information characterized by a protocol.
Background
KVM is an abbreviation for Keyboard Video Mouse. The KVM switch allows you to access and control the computer by directly connecting to the keyboard, video and mouse (KVM) ports. KVM technology has evolved from the first basic SOHO office type to enterprise IT infrastructure management systems. Servers and devices located in multiple remote locations can be easily accessed directly from the kvm client management software. The KVM over IP solution has a sophisticated multi-site failover functionality, a direct interface that conforms to the new server management standard (IPMI), and a function to map local storage media to a remote location.
At present, the file copying method applied to the KVM system between computers is generally realized through a network or a mobile storage device, in many environments, the computers are not connected with the Internet for safety, and if the files are copied by the mobile storage device, the files are too troublesome, and possibly two computers are distributed on different floors.
If the factory industrial park is involved, due to the fact that the factory industrial park occupies a wide area, when files need to be copied by the mobile storage device, the two computers are distributed in different areas.
