Dominion KX II – Frequently Asked Questions

How can I reduce
bandwidth?
KX II provides a variety of settings in our remote clients for the user to optimize
bandwidth and performance. The default settings will provide an at-the-rack
level of performance in standard LAN/WAN environments with economical use
of bandwidth.
Bandwidth management settings include the connection speed and color depth.
To reduce bandwidth:
Connection speed. Reducing the connection speed can significantly reduce the
bandwidth used. In a standard LAN/WAN environment, setting the connection
speed to 1.5 or 1 Mb per second will reduce bandwidth while maintaining good
performance. Settings below this will further reduce bandwidth and are
appropriate for slow bandwidth links.
Color depth. Reducing the color depth will also significantly decrease
bandwidth and increase performance, but fewer colors will be used, resulting in
video degradation. This may be acceptable for certain system administration
tasks.
For slow Internet connections, the use of 8-bit color or lower bit depths can
reduce bandwidth and improve performance.
Other tips to decrease bandwidth include:
• Use a solid desktop background instead of a complex image
• Disable screensavers
• Use a lower video resolution on the target server
• Uncheck the “Show window contents while dragging” option in
Windows
• Use simple images, themes and desktops (e.g., Windows Classic)
What should I do on slower
bandwidth links?
The connection speed and color depth settings can be tweaked to optimize
performance for slower bandwidth links.
For example, in the Multiplatform Client or the Virtual KVM Client, set the
connection speed to 1.5 Mb or 1 Mb; and the color depth to 8 bit.
Even lower connection speeds and color depths can be used for very low
bandwidth situations.
For modem connections, the KX II will automatically default to a very low
connection speed and reduced color depth to optimize performance.
I want to connect over the
Internet. What type of
performance should I
expect?
It depends on the bandwidth and latency of the Internet connection between
your remote client and the KX II. With a cable modem or high speed DSL
connection, your performance can be very similar to a LAN/WAN connection.
For lower speed links, use the suggestions above to improve performance.
I have a high bandwidth
environment. How can I
optimize performance?
The default settings will provide strong performance in a high bandwidth
environment.
Ensure that the connection speed is set to 100 Mb or 1 Gb and the color depth
is set to 15-bit RGB color.
What is the maximum
remote (over IP) video
resolution supported?
The Dominion KX II is the first and only KVM-over-IP switch to support full high
definition (HD) remote video resolution – 1920x1080.
In addition, popular widescreen formats are supported, including 1600x1200,
1680x1050 and 1440x900, so remote users can work with today’s higher
resolution monitors.
