Question
Answer
How far can my servers be from
Dominion KX III?
In general, servers can be up to 150 feet (45
m) away from Dominion KX III, depending on
the type of server. (See Target Server Video
Resolution Supported Connection
Distances and Refresh Rates (on page 113))
For the D2CIM-VUSB CIMs that supports
virtual media and Absolute Mouse
Synchronization, a 100-foot (30 m) range is
recommended.
Some operating systems lock up
when I disconnect a keyboard or
mouse during operation. What
prevents servers connected to
Dominion KX III from locking up
when I switch away from them?
Each Dominion computer interface module
(DCIM) dongle acts as a virtual keyboard and
mouse to the server to which it is connected.
This technology is called KME
(keyboard/mouse emulation). Raritan’s KME
technology is data center grade, battle-tested
and far more reliable than that found in
lower-end KVM switches: it incorporates more
than 15 years of experience and has been
deployed to millions of servers worldwide.
Are there any agents
that must be installed on servers
connected to Dominion KX III?
Servers connected to Dominion KX III do not
require any software agents to be installed
because Dominion KX III connects directly via
hardware to the servers’ keyboard, video and
mouse ports.
How many servers can be
connected to each Dominion KX III
unit?
Dominion KX III models range from 8, 16 or 32
server ports in a 1U chassis, to 64 server ports
in a 2U chassis. This is the industry’s highest
digital KVM switch port density.
What happens if I disconnect a
server from Dominion KX III and
reconnect it to another Dominion
KX III unit, or connect it to a
different port on the same
Dominion KX III unit?
Dominion KX III will automatically update the
server port names when servers are moved
from port to port. Furthermore, this automatic
update does not just affect the local access
port, but propagates to all remote clients and
the optional CommandCenter Secure Gateway
management appliance.
