KVM Selection Guide

Which KVM Switch is best for me?

KVM switches are used to connect users to their computers. There are many types of KVM switches to meet a wide variety of customer needs. Here are the major questions to consider:

  1. How many users and computers are there?
  2. What are the distances between the users and the computers?
  3. What type of cabling will connect the users and computers?

Here’s some quick advice. If you want point-to-point access to a single computer, then look into KVM Extension. If you have a few computers in close proximity, then a Desktop Switch may be right for you. If you have a small server room or lab within 1000 feet of the users, then look into Analog Matrix Switches. KVM-over-IP Switches provide flexible, local and multi-user IP access of 8 to 64 computers, that scales to thousands of computers via Raritan’s Centralized Access and Management System.

The table below summarizes the types of KVM switches, from enterprise wide IP access to the extension of a single computer. Look at the Typical Applications column for the type that best matches your application.
