A Brief Historical Overview
|
Keyboard,
Video and Mouse Switches (KVMS) have been around for more than a
decade. It started in the late 1980's with a single customer's
request. That customer simply wanted to reduce the number of
computer peripherals. Today, that original concept still
holds true! Data centers, computer labs and even small offices are
using KVM switches to reduce the cost of using, and eliminate the
redundant hardware that just seems to get in the way.
The original single
console KVM switch provided simple switching functions for
keyboards and monitors. They are used mostly in computer and
testing labs by technicians who just needed space savings and
reduced movement within the lab. They provided keyboard emulation
with video amplification, buffering and termination. By the early
1990's, mouse support was being included that attracted a wider
range of users as the KVM Switch could address more platform
installations that were heavily dependent on the GUI interface
using the mouse for navigation.
As the market awareness
grew, public opinion continued to shape the design of newer KVMS
products being released. In early 1995, the first multi-console
KVM Switch was released supporting a range of consoles connected
to the same KVM switch chassis. These products allowed multiple
consoles to independently access every computer connected to the
hardware. Now, simultaneously control of individual server systems
could be managed through the same infrastructure.
