KVM Switch Selection Guide

KVM Switches: What is best for you?

KVM switches are used to connect users to their computers. There are many types of switches to meet a wide variety of customer needs, but choosing the best kvm switches can be a challenge. 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 (or network) will connect the users and computers?
  4. Any special needs such as 4K video, high performance KVM or protecting classified information?

Here’s some quick advice to find the best kvm switch. 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 are a government or military worker who needs access to systems at different classification levels, then a Secure Desktop Switch is for you. If you have a smaller server room or rack within close proximity to the users, then look into a KVM Matrix Switch. 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. For 4K, broadcast, video or dynamic applications consider a high performance KVM switch.

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.
