7 Things To Consider When Choosing KVM Switch

In the past, the KVM switch was a hardware device that allowed users to control one or more computers from one or few keyboards, mouses or video monitors. These days, the KVM switch can be either a hardware or a software device. Most KVM switches on the market are software devices. If you have any doubts whether the KVM switch is the right solution for you, there are few important factors that need to be considered. Here are 7 things you need to consider before buying a KVM switch:

KVM Over IP Device – If you are planning to use a KVM switch over IP device, you should know that there are different ways to implement it. By implementing a KVM switch, you will get a network-based management approach that will allow you to gain BIOS-level access of the attached server. The KVM devices allow all connected computers to be remotely controlled via local area networks, telephone-lines and wide area networks.

Remote Power Management Functionality – If you integrate a remote reboot device (connect your computers to a server), you can access your computer from everywhere. Today, the remote power management is a great solution for users that travel often abroad.

Number Of Users – For more users, there are simple KVM switches designed to deal with dozens of servers. There are also heavy-duty systems that allow several administrators to control the servers.

Audio Support – Most KVM switches on the market provide audio support. The newer models usually come with audio support, but the question you need to consider is whether you need audio functionality.

Performance & Resolution – Every KVM switch provides specific performance and comes with specific resolution. For standard requirements, there are KVM switches with maximum of 1600×1200 at 60Hz over IP, while for high-resolution requirements, there are specifically designed KVM switches, called analog switches.

Distance Requirements – Although users can access a server via KVM-over-IP devices from any distance, for some switches the distance is a concern. For greater distances, fiber extenders are the best choice, as they allow access over 9 kilometers.

Serial Devices Support – Some popular manufacturers of KVM switches provide serial devices support. Some switches provide a serial devices support via dongles, while others provide a serial devices support at the switch level through the coax cables.
