At its core, a KVM switch is simply a piece of hardware that allows one person to control multiple computers using a single keyboard, monitor, and mouse from a centralized location. The earliest examples of KVM switches on record actually pre-date the invention of the mouse itself, which is why they were originally used as testing tools for motherboard and production server quality tests.
With the advent of mouse interfaces like PS/2, USB, Sun, and Mac, however, the concept itself evolved into something much more meaningful than those original applications. For many organizations, KVM switches act as the backbone of their entire technological infrastructure - even if not everyone has necessarily come to realize that simple fact quite yet.
What Are the Four Categories of KVM Switches?
There are a few different categories of KVM switches available depending on the goals that you're trying to accomplish. From a computer access and control perspective, it breaks down into two options:
From an actual application and technology perspective, there are two additional types of KVM switches available:
The Major Benefits of KVM Switches
The core advantage of using KVM switches extends far beyond the simple ability to centralize access and control for multiple servers, PCs or workstations. Perhaps the most significant benefit comes by way of increased productivity. A company's IT staff can now respond to incidents from any location, leading to a much faster response rate and an easier recovery process when a disaster happens to strike.
A KVM switch can allow a critical IT staff member to instantly reach the BIOS of an affected machine, even if they're miles away from the machine itself, dramatically cutting down on how long it takes to diagnose the problem. This option is not available with software-based remote access solutions, which typically do not offer the type of "out-of-band access" function which is needed.
Speaking of "out-of-band access", another major benefit of KVM switches comes by way of improved business continuity and security in general. Even if the corporate network is down, IT personnel can still access, control, and manage a company's servers in an emergency situation. The data transmitted through KVM-over-IP switches, in particular, is also encrypted using advanced techniques like AES, FIPS 140-2 and Smart Card authentication, leading to a dramatically improved sense of security in a situation where this could not be more valuable.
