Introduction about KVM Switch

A KVM stands for “Keyboard, Video and Mouse”. This switch allows you to control multiple computers or servers with a single keyboard, mouse and monitor. KVM Switches can usually be found in IT departments or server rooms where space is limited and a keyboard, mouse and monitor cannot be connected to each individual server or computer.

Most KVM Switches require you to purchase cables unless they include them in the box. Some 2 port KVM’s have built-in cables which are ideal for home users. No additional cables are required and you have the ability to manage 2 computers or servers easily with one KVM. When purchasing a KVM Switch you should always check what kind of cables are required. Some KVM’s require proprietary cables which are only provided by the same manufacturer of the KVM.

A KVM Switch Can Be Daisy-Chained

KVM Switches can come in different styles and include various features. They can be as small as a 3″ x 3″ box which allows you to control 2 PC’s, to large rackmount units which allow you to control 64 or 128 servers or computers. KVM’s can also be daisy-chained which is done by connecting one KVM to another. This allows you to control an even higher amount of servers and computers.

Multi-monitor KVM’s have also been designed which connect to servers or computers with multiple built-in video cards. This allows two monitors to be connected to a single LCD KVM Switch which would then display video from both video cards in each server or computer.

Another functionality of some KVM’s is DVI support.  DVI (Digital Vision Interface) provides you a much clearer image. This is especially ideal for graphic designers, web designers and engineers.

KVM Switches can help your IT department to save valuable space in server rooms and allow each server and computer to be easily maintained from one location with one keyboard, mouse and monitor. They can include a wide variety of benefits to all PC users in any industry.
