KVM Switches & Server Console Solutions

KVM stands for Keyboard, Video, and Mouse.

A KVM switch allows one set of user-interface devices to control multiple computers or servers.

Depending on the KVM platform, an administrator can share:

• A keyboard
• A monitor
• A mouse or touchpad
• USB peripherals
• Audio devices
• Remote network access

KVM systems can reduce equipment clutter while providing centralized server and computer administration.

What Is a KVM Switch?

A KVM switch connects multiple computers or servers to one keyboard, display, and mouse.

The administrator selects which connected system to control, and the KVM routes keyboard, video, and mouse communication to that system.

Selection methods can include:

• Front-panel buttons
• Keyboard hotkeys
• On-screen menus
• Mouse commands
• Remote web interfaces
• Dedicated remote console stations

Available switching methods depend on the KVM model.

Why Use a KVM Switch?

A KVM switch can reduce the number of keyboards, monitors, and mice required to administer multiple systems.

Benefits can include:

• Reduced rack and desk clutter
• Centralized server administration
• Reduced monitor requirements
• Faster access to multiple systems
• Local BIOS-level administration on supported KVMs
• Remote management with KVM over IP
• Improved rack-space efficiency

KVM Switch vs. Separate Keyboard & Monitor

Without a KVM switch, each server or computer can require its own keyboard, display, and mouse or require peripherals to be moved between systems manually.

A KVM switch centralizes those controls.

This becomes increasingly valuable as the number of systems grows.

KVM Switches for Servers

Server environments are one of the most common KVM applications.

A rack KVM can provide console access to multiple servers from a central administration point.

KVM access can be useful when:

• The operating system is unavailable
• Network services have failed
• BIOS or firmware access is required
• A server must be rebooted
• Initial system configuration is being performed
• Remote operating-system tools are unavailable

Local KVM Switches
