I am always impressed by the number of possibilities for controlling servers and their attachments such as the keyboard, monitor and mouse using a KVM switch. Rackmount Keyboard products and Rackmount Monitor keyboard combos were monumental milestones for the computer back office. It seemed as if every IT organization, from large data centers to small businesses, were opting to remove CRT monitors and desktop keyboards which became unnecessary after the KVM switch came onto the market.
Basically, a KVM (which stands for keyboard, video, mouse) switch is used to connect and to control multiple computers from a single operator station. The rack mount keyboard consists of a sturdy metal tray, a computer keyboard and tracking device (a trackball, touchpad or even a wired mouse). You have the option of having an LCD monitor installed within the tray. These rackmount units are ideal for use in data centers, information technology, command centers, commercial, military and government applications.
In more modern models, the KVM switch is built directly into the rackmount keyboard thereby eliminating another device to mount in the rack. All of this takes up as little as 1RU of space in the rack.
