A KVM Switch is a hardware device that allows you to control multiple computers via a single keyboard, monitor, and mouse (KVM). The first KVM switch was created as a testing tool for motherboard and production server quality tests, and only supported video and keyboard since the mouse hadn’t been invented at that time. And as computer technology continued to evolve, so did KVM switches which led to the development of a variety of types for different systems and applications. Here are the four categories of KVM switches.
From a computer access and control perspective, the KVM switch can be categorized into two main types:
From an application and technology perspective, KVM switches can be divided into the following two types:
Each of these main four types of KVM switches also needs to support a variety of platforms and technologies. For instance, KVM switches need to support different keyboard and mouse interfaces like PS/2, USB, Sun, Mac; and different video interfaces like VGA, DVI, ADC, HDMI, and display ports. KVM switches also need to support different platforms such as Windows based PC/Servers, Mac, Sun, Linux, and more. Computer interface modules (CIM) are available in a variety of formats in order to support these different video and input interfaces.
It’s clear to see that as applications and technologies evolved over the past three decades, they’ve required KVM switches to evolve and keep pace as well. Fortunately, KVM technology is at a point where combinations are unlimited to accommodate the breadth of technologies used in server rooms and data centers.
