The KVM switch plays an important role in the space where the racks of the server room and the keyboard are not convenient to store multiple display and keyboard spaces. The KVM switch can monitor and control multiple computers and servers from locally or remotely. The KVM console consisting of keyboards, mouses and displays is the most convenient and economic ideal solution.

What is a KVM switch

The KVM switch is also known as a multi -computer controller. One KVM switch can control 2, 4, 8, 16, or more computers or servers. The simple interface is easy to operate. It can be controlled by connecting around the world. The control port of the KVM switch is mainly used to connect the USB port and the VGA port of the USB port and the monitor of the keyboard and mouse. The service port has a different number of RJ45 ports to connect to the computer or server. Come to connect.

KVM switch work principle

The KVM switch is mainly to securely access computers, servers and other devices consisting of keyboards, mouses, and monitors.

The advantage of the KVM switch

① It can save monitors, keyboards, mouse spaces. For example, the KVM switch of the 8th road can control 8 servers with a mouse, keyboard and display.

② Improve operational efficiency. In the past, when faulty, people needed to find people to find it. Not only did it cost time and efficiency, but now a KVM switch can control all machines, which not only saves manpower but also improves efficiency.

③ Save cost. Reducing the consumption of space and manpower can save a lot of costs, and controlling the cost of network operation is one of the key factors for the success of the company.

④ Local or remote management. Using KVM switching for local or remote management can ensure the 24 -hour uninterrupted management and maintenance of the network, which can ensure the security and stability of the network.

How to use the KVM switch

The KVM switch switching method is generally: button switching, OSD menu switch, shortcut key switch.

① The button switches uses the physical buttons above KVM. Press the physical button directly to select the corresponding server.

②SD menu is a software inside KVM. You can use the mouse to select the corresponding server for switching according to the server name displayed on the menu.

③ The shortcut keys are generally combined keys, such as CTRL and a certain data key, 1, 2, 3, and 4 servers. Select CTRL+1 to select the first server, which is simple and convenient.

The application of KVM switching

The KVM switch uses the CAT5 / 5E / 6 cable to connect to the server, supporting a local user and a remote user to operate multiple servers at the same time around the world, and support the resources of local and digital channel quality inspection. The flexibility of the KVM switchinger is enough to meet the needs of multiple computers and multi -server applications such as household office, small and medium -sized enterprises, small and medium -sized machine rooms.

Comparison of KVM switching and KVM light -end machine/virtual machine

(1) The difference between the KVM switch and the KVM light -end machine

The KVM light -end machine is composed of a KVM transmitter and a KVM receiver, which is mainly used for signal transmission in the multimedia application system. The KVM switch is mainly used to monitor and manage multiple computers and multiple servers. There is a big difference between the nature of the two.

(2) The difference between the KVM switch and the KVM virtual machine

The KVM switch is a hardware switching device, and KVM is the abbreviation of Keyboard Video Mouse. The KVM virtual machine is a commonly used virtual machine under the Linux system. It is the abbreviation of Kernel-Based Virtual Machine. It is an open source system virtualization module.
