KVM refers to "keyboard, video, and mouse". These three items
are collectively known as a KVM console.
The main purpose of a KVM switch is to enable a single KVM
console to connect to multiple devices. This lets users access
and control multiple computers or servers from the console.
Most businesses rely on servers to perform behind-the-scenes
work that help the business run smoothly. The most common
types of servers are mail servers, database/file servers,
web servers, and application servers (SAP, ADP).
Due to their mission-critical role, corporate servers are
typically placed in a secure environment called a data center
or server room.
Server rooms can be a small closet or room, or a very large
room(s) containing hundreds, if not thousands of servers.
These are often referred to as data centers. They are designed
and built to protect the servers they contain, with highly
reliable power sources and generators; high levels of physical
security; and high-end heating, ventilation, and air conditioning
(HVAC) systems.
The main purpose of a KVM Switch is to enable a single KVM
console to connect to multiple devices, enabling the user
to selectively control one device or another from their own
KVM console.
By allowing one or more users to access and control multiple
servers, KVM switches enable businesses of all sizes to realize
the following benefits:
- Reduce costs - a KVM switch eliminates
the need for connecting a keyboard, video monitor and
mouse to each server, so a business only needs one or
very few keyboards, video and mouse devices to control
and manage many servers. This not only lowers hardware
costs, but also frees up valuable physical space, along
with reducing demands on electrical power and heating
and cooling systems.
- Improved business continuity - KVM
switches allow "out of band" access to a company's servers
and other IT devices. As such, they are not dependent
on a corporate backbone or network. Thus they allow IT
personnel to access, control and manage the company's
servers even if the corporate network itself is down.
A KVM switch can even enable a complete system reboot
from a remote location.
- Hardware platform and OS independence
- KVM switches work in heterogeneous server environments.
They are not dependent on the hardware or operating system
from a specific manufacturer. As such, they can function
in corporate IT environments that have servers from different
manufacturers like HP, IBM, and Sun , that run on different
operating systems like Solaris, Unix, or Windows.
