Advantages of A KVM Switch

A KVM Switch (keyboard, video and mouse) is a hardware device that allows a user to control multiple computers from one or more sets of keyboards, video monitors and mice. These switches are often found in data centers where multiple servers are placed in a single rack. By pressing a button on the KVM switch, the administrator can change control from one server to next. These switches also help in saving the cost of purchasing dedicated keyboards, mouse and monitors. It also saves space in the server room and limits cable clutter.

When a typical PC is starting up, the operating system will automatically try to detect the signals of keyboard and mouse just like water sensors. After confirmation of connectivity, the screen displays the start up page. As a result the booting of a single PC is dependent on its keyboard and mouse. For control of multiple PCs, several sets of keyboards, mouse and monitor is needed. This could be space consuming as well as costly. KVM switch solves all the problems.

When purchasing a KVM, the choice is based upon the number of PCS to be controlled by this switch. KVMs with few ports are convenient to use without the need of installing of software. They can also be managed by using hot keys and switch keys. KVMs equipped with only few ports do not need external power supply. It is important that a KVM switch ensures simulated keyboard and signals reach each PC and that during switching there is no affect on the PC's CPU operation.
