How much bandwidth

require?
does Dominion KX
require?
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.
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 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 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
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 table below summarizes some use
cases and the required bandwidth utilization at Dominion KX’s default
settings on a 10Mbit/s network:

Ethernet interfaces?
Dominion KX’s
Ethernet interfaces?
Dominion KX offers two 10/100 speed Ethernet interfaces, with
configurable speed and duplex settings (either auto-detected or
manually set). Dominion KX does not require a gigabit Ethernet
interface because its output (see above question) would never even
come close to exceeding the 100Mbit/sec limit of 10/100 Ethernet
networking.

Can I access Dominion
KX over a wireless
connection?
KX over a wireless
connection?
Yes. Dominion KX not only utilizes standard Ethernet, but also uses
very conservative bandwidth with very high quality video. Thus, if you
have a wireless client with network connectivity to Dominion KX, you
can configure and manage your servers at BIOS-level wirelessly.
