Ethernet Networking
Q. How much bandwidth does
Dominion KX require?
A. 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 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:
Idle Windows Desktop 0 Mbit/s
Move Cursor Around Desktop 0.18Mbit/s
Move Static 400x60
0
Window/Dialog Box
0.35Mbit/s
Navigate Start Menu 0.49Mbit/s
Scroll an Entire Page of Text 1.23Mbit/s
Run 3D Maze Screensaver 1.55Mbit/s
Q, What is the slowest
connection (lowest bandwidth)
over which Dominion KX can
operate?
A. The slowest connection is 20kbits per second (a slow dial-up modem).
Q. What is the speed of
Dominion KX’s Ethernet
interfaces?
A. 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.
Q. Can I access Dominion KX
over a wireless connection?
A. 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.
Q. Can Dominion KX used
over the WAN (Internet), or
just over the corporate LAN?
A. Yes. Whether via a fast corporate LAN, the less predictable WAN (Internet), a cable
modem, or dial-up modem, Dominion KX’s KVM Over IP technology can accommodate
your connection. Raritan’s IP-Reach KVM Over IP technology is integrated into every
Dominion KX unit. Raritan pioneered configurable video compression technology,
leading the industry by years, as evidenced by its awards.
