Question Answer
How much bandwidth
does the Dominion KX
require? The Dominion KX offers integrated IP-Reach technology - the very
best video compression available. Raritan has received numerous
technical awards confirming its high video quality transmissions
and the low bandwidth utilization.
Raritan pioneered the KVM Over IP functionality that allows
users to tailor their video parameters to conserve network
bandwidth. For instance, when connecting to the Dominion KX
through a dial-up modem connection, video transmissions can be
scaled to grayscale - allowing you to be fully productive while
ensuring high performance.
With that in mind, the following data refers to the Dominion KX at
its default video settings - again, these settings can be tailored to
your environment. They can be increased to provide even higher
quality video (color depth), or decreased to optimize for low-
speed connections.
As a general rule, a conservative estimate for bandwidth
utilization (at the Dominion KX's default settings) is
approximately 0.5Mbit/seconds per active KVM user (connected to
and using a server), with very occasional spikes up to
2MBit/seconds. This is a very conservative estimate because
bandwidth utilization will typically be even lower.
Bandwidth required by each video transmission depends on what
task is being performed on the managed server. The more the
screen changes, the more bandwidth is utilized. The following list
summarizes some use cases and the required bandwidth
utilization at the Dominion KX's default settings on a 10Mbit/s
network:
• Idle Windows Desktop - 0 Mbps
• Move Cursor Around Desktop - 0.18Mbps
• Move Static 400x600 Window/Dialog Box - 0.35Mbps
• Navigate Start Menu - 0.49Mbps
• Scroll an Entire Page of Text - 1.23Mbps
• Run 3D Maze Screensaver - 1.55Mbps
