Why KVM Switch Had Been So Popular till now?

What is KVM?

KVM is a short form of Keyboard, Video (track ) and Mouse, that is sometimes also known as a PC switch or an Electronic switch. A KVM Switch is a hardware device, used in data centers, that makes it possible for the management of multiple computers from one keyboard, monitor and mouse (KVM). This switch then enables data Centre members to connect to some server in the stand. But, It’s is quite different than a traditional data switch. The most important role of a KVM switch is to control switch and handle several PCs through a single keyboard monitor and mouse.

Why we need a KVM switch?

Now, the majority of us do not have to use 2 computers simultaneously. Actually, using a computer at one time can be a challenge for you. But, there are scenarios where using one keyboard, mouse, and screen with several machines can be extremely practical.
As an instance, software developers can use a KVM switch to alternate between a few computers using different operating systems. This lets them test their applications on multiple platforms. Network administrators frequently use KVM switches to track and control many servers at one time. These KVM switches can support eight or more computers at the same time. Simply by pressing a button on the KVM switch, the administrator can see the screen of any device on the switch and control it using one mouse and keyboard.
Obviously, KVM switches may also be utilized by the regular home user. Some may find it most helpful to have 2 computers in their desk, like a home and work computer. In such scenarios, a KVM switch can adapt both servers, letting them share the same monitor, keyboard, and mouse.

Different types of KVM?

There are lots of forms of KVM switches which are developed for meeting different requirements of users which were clarified here on the basis of how they manage input/output devices such as a touchscreen, keyboard, mouse and so forth
Enumerated KVM Switch — it’s also known as hub-based USB KVM switch, which needs to experience USB enumeration whenever the user switches to a new port or platform. Each time you change to another interface, you need to follow along with the whole initiation procedure very similar to physically plugging and unplugging a USB device into a system. These are utilized for little home office setups and allow the only user to control multiple computers in the single console.
Multiuser KVM Switch- inside this system, dedicated USB interfaces are assigned to a specific set of mouse and keyboards switching controllers. The technology demands many users to handle a large number of computers and data servers. Massive installations need multi-user KVM switches and this method enables around 16 users to get 64 servers. The KVM switches utilize fundamental emulations to support fundamental characteristics of mouse and keyboard
Analog KVM Switch – These switches support varied platforms and technologies that are operated through single direct cable connection between computer and console, which passes through the switch. It has advanced features like virtual media and is used to control access to server platforms and devices by a single user. Depending on user’s required bandwidth, these switches affect its cost and quality while allowing resolutions at 60 Hz.
Digital KVM Switch – These switches are used to control servers from varied IP connections located in remote locations. Administrator can have direct control over company LAN, but computers have a direct connection to KVM switch, though user may not be directly in touch with KVM switch. The KVM over IP switch allows users to control multiple servers via the TCP/IP network though only one person is seated at the controls.
Analog KVM Switch — These switches support diverse platforms and technology which are operated via single direct cable link between console and computer, which moves through the switch. It’s advanced features such as virtual media and is engaged to control access to server devices and platforms from a single user. Based on user’s needed bandwidth, such switches influence its price and quality when enabling resolutions at 60 Hz.
Digital KVM Switch — All these switches are utilized to control servers from diverse IP connections found in distant locations. The administrator may have direct control over business LAN, but computers have a direct link with KVM switch, however, the user might not be directly connected with KVM switch. The KVM over IP switch allows users to control many servers through the TCP/IP network through just 1 individual is seated in the controls.

Point to be  Noted Before Buying a KVM Switch

All these above four KVM switches must support a number of keyboards and mouse ports, which use different video ports and display boards. The dimensions of KVM switch which you will need depends upon several variables such as servers and computers which must be controlled and prospective requirements. When you buy KVM switch, start looking for a system that does not call for running private computers to reboot for linking in a multi-user atmosphere
When deciding upon a KVM, then there are lots of important things to remember. The best ten factors when picking your KVM Switch:
  • ·         Digital vs. Front-End IP Switch
  • ·         Support for Audio
  • ·         Integration of Remote Power Management Functionality
  • ·         CAT5 Switches
  • ·         Resolution and Performance
  • ·         Support for Serial Devices
  • ·         Bandwidth
  • ·         Distance Prerequisites
  • ·         Security & Authentication
  • ·         Amount of Users
