What’s a KVM switch?
KVM switches are widely used in families and businesses. In fact, there are numerous different use scenarios. The most common uses are these two mentioned below:
- KVM switch for home office
WFHers may be working on the work computer and gaming on other devices (for example a Razer, a Nintendo, or the PS5 console). Installing multiple sets of KVM for all devices is unnecessary if you get a KVM switch. Without this small metal box, arranging or moving bulks of KVM could be the cause of headaches. Frequent plugging may accelerate the wearing off of the cables and ports. A KVM switch is a perfect way to integrate your devices into one system.
- KVM switch in a data center
If you are in charge of a data center, you may be familiar with KVM extenders, which extend KVM signals to the offices and grant operators access to designated devices. While a KVM switch is a must for the engineer who maintains the whole room of servers.
The switch helps route the KVM to connect the needed server among the bulks on the racks and by using one display, keyboard and mouse, the professional is able to control any one of the servers in the room.
What’s KVM?
KVM stands for “Keyboard, Video, Mouse”. In a broader sense, it refers to a display, a keyboard, a mouse, and other USB peripherals. Sometimes people use “KVM” interchangeably with “KVM switch”. (This KVM is out of our discussion)
The main function of a KVM switch is to connect multiple computing devices with one or more displays, and other USB peripherals. Hence, one fixed console could be used to control a set of PCs or other servers (like gaming consoles).
A KVM switch is built as a box in metal. For most designs, there are ports for the USB host, video inputs and outputs on the back panel, and a USB hub and switch buttons on the front panel.
Depending on the product specs, users could switch among different servers by pressing a button on the box, using an IR remote, hitting a certain Hotkey on the keyboard, or changing settings via a UI on the browser. The key is to connect the console to whichever device you need fast and hassle-free.
Troubles without a KVM switch
Imagine there is no KVM switch in the world, what troubles would sustain and piss you off?
- Spending money for multiple sets of consoles (monitor, keyboard, mouse, and other peripherals) to control each server. More cable costs.
- Allowing multiple sets of consoles to squeeze your living/work space and time (to maintain them).
- Bringing more clusters of cables and heat into the room.
- Facing heavy stress if any movement is likely to happen.
- Impossible to maintain a data center of servers without a KVM switch.
The benefits of a KVM switch are self-evident here. It helps save hardware costs, reduce clusters of cables, save space and make the whole setup flexible and mobile.
