What Is A KVM Switch?
KVM (keyboard, video, mouse) is a device that allows you to use multiple computers from one keyboard, video and mouse. The KVM switches can be especially helpful in rooms with insufficient space for more monitors and keyboards, while multiple computers are required for proper operation. Economical and convenient, the small KVM switches are incredibly flexible and can fit the needs of any application. The number of computers (or servers) that you are able to control with one KVM switch depends on the amount of available ports included on it. Usually, KVM switches allow control of up to 8 computers, but there are some specific models that allow a control up to 32 computers (or servers).
How Do KVM Switches Work?
The KVM switches has a very simple working principle, but efficient. Computers you want to control with one keyboard, video and mouse are connected to a KVM switch with proper cables and that's it. To switch from one to another computer, you just need to press a single button, if available, or a combination of hot keys on the keyboard.
What Are The Most Common Applications of KVM Switches?
The KVM switches are very easy to install, and even easier to operate. Many homeowners use these functional devices to use the same keyboard, video and mouse from the old computer to control the new computer/s. Aside from home use, the KVM switches are extensively used in businesses that require one person to use several computers. Also, they are widely used in server rooms where one computer is able to access one server at a time. The KVM switches are also used in data centres, where there are lots of servers placed in one rack. With one of these small devices, you can connect to any server in the rack.
How To Choose A KVM Switch?
When it comes to choosing a KVM switch, there are so many types of KVM switches you can consider. But every one is designed for different applications and you need to choose carefully if you want to avoid costly mistakes and decrease in productivity. The four important factors when choosing a KVM switch for your application are:
How many computers you want to control?
Do you want to operate the switch from your desk or from a rack?
Do you need an on-screen display for easier switching between computers?
Are you likely to ever increase the number of computers you control (choose a KVM switch with few more available ports than required)?
