KVM-over-IP performance?
Answer
Consult the user guide for the available profiles and for more
information.
Dominion KX II offers next-generation KVM-over-IP technology –
the very best video compression available. Raritan has received
numerous technical awards, confirming its high video quality
transmissions and the low bandwidth utilization.
The Dominion KX II digitizes, compresses and encrypts the
keyboard, video and mouse signals from the target server and
transmits IP packets over the IP network to the remote client to
create the remote session to the user. The KX II provides an at-the-
rack experience based on its industry-leading video processing
algorithms.
Screen changes, i.e., video accounts for the majority of the
bandwidth used – and keyboard and mouse activity are significantly
less.
It is important to note that bandwidth is only used when the user is
active. The amount of bandwidth used is based on the amount of
change to the server's video display screen.
If there are no changes to the video – the user is not interacting
with the server – there is generally no bandwidth used. If the user
moves the mouse or types a character, then there is a small
amount of bandwidth used. If the display is running a complex
screen saver or playing a video, then there can be a larger amount
of bandwidth used.
In general, there is a trade-off between bandwidth and
performance. The more bandwidth available, the better
performance can be. In limited bandwidth environments,
performance can degrade. The Dominion KX II has been optimized
to provide strong performance in a wide variety of environments.
