This article mainly introduces what the kvm switch refers to, which can be used for reference by friends who need it. I hope you will learn a lot after reading this article. Next, let the editor take you to learn about it.

KVM switch, also known as multi-computer controller, a KVM switch can control 2, 4, 8, 16 or more computers or servers, the network connection between them can be controlled in the world no matter near or far; the control port of KVM switch is mainly used to connect the USB port of keyboard and mouse with the VGA port of monitor.

The KVM switch plays an important role in the space where the rack of the server room is not convenient to store multiple monitors and keyboards. The KVM switch can monitor and control multiple computers and servers locally or remotely. The KVM console composed of keyboard, mouse and display screen is the most convenient and economical solution.

1. What is a KVM switch

KVM switch, also known as multi-computer controller, a KVM switch can control 2, 4, 8, 16 or more computers or servers, its simple interface is easy to operate, and the network connection between them can be controlled all over the world. The control port of the KVM switch is mainly used to connect the USB port of the keyboard and mouse with the VGA port of the monitor, while the service port has different numbers of RJ45 ports to connect the computer or server, and they can be connected by CAT5, CAT5E and CAT6.

2. The working principle of KVM switch

The KVM switch can securely access computers, servers and other devices from local or remote users through the console composed of keyboard, mouse and monitor, and can control local or remote users using the network.

3. Advantages of KVM switch

① can save the space of monitor, keyboard and mouse. For example, the 8-way KVM switch can control eight servers with a set of mouse, keyboard and monitor.

② improves operational efficiency. In the past, when there is a fault, people need to take the initiative to find it, which not only takes time and energy and low efficiency, but now a KVM switch can control all the machines, which not only saves manpower but also improves efficiency.

③ saves money. Reducing the consumption of space and manpower can save a lot of costs, and controlling the network operating cost is one of the key factors for the success of the enterprise.

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

4. How to use the KVM switch

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

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

The ② OSD menu is the internal software of KVM, which can be switched by selecting the corresponding server with the mouse according to the server name displayed on the menu.

③ shortcuts are generally combined keys, such as Ctrl and a data key, 1, 2, 3, 4 servers, choose Ctrl+1 choose the first server, simple and convenient.

5. Applicable scope of KVM switch

The KVM switch uses CAT5 / 5e/6 cable to connect the server, supports a local user and a remote user to operate multiple servers at the same time anywhere in the world, and supports the sharing of local channel and digital channel quality inspection resources. The flexibility of the KVM switch is sufficient to meet the needs of any home office, small and medium-sized enterprises, small and medium-sized computer rooms and other multi-computer and multi-server applications.

Comparison between KVM switch and KVM Optical Terminal / Virtual Machine

(1) the difference between KVM switch and KVM optical terminal.

KVM optical terminal is composed of KVM transmitter and KVM receiver, which is mainly used for signal transmission in multimedia application system. The KVM switch is mainly used to monitor and manage multiple computers and servers, and the nature of the two is very different.

(2) the difference between KVM switch and 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, which is the abbreviation of Kernel-based Virtual Machine, is an open source system virtualization module.

Thank you for reading this article carefully. I hope the editor can share what the kvm switch refers to is helpful to everyone. At the same time, I also hope that you can support us, pay attention to the industry information channel, and find out if you have any problems. Detailed solutions are waiting for you to learn!
