Eight Critical Features For
KVM Systems
By Chris Hsu and Dawn Mangine, Black Box

H

ere's a checklist to use as you
shop for a future-proof, highperformance digital KVM switch or
switching and extension systems. It's
easy to remember as FAR-PARSS.
Flexibility: Any enterprise-wide
KVM system should be flexible enough
to input and output many types of
video and peripherals. Video signals
such as DVI, HDMI, and VGA should
be supported with resolutions ranging
from 1080p to 4K. Other signal types
to look for are audio and USB 1.1 or
2.0 for peripherals like keyboards and
mice.
A flexible system should also be
scalable for future growth. The KVM
switches need to support current and
future users with enough ports. Look
for a KVM system that can replace
a video-only router. A management
controller
enables
centralised
administration of the system.

Accuracy: When a KVM system can
support video resolutions of 1920 x
1080 at 60 Hz or 3840 x 2160 at 60 Hz,
test to make sure video does not lag
or drop frames with rapidly changing
content. Not all analogue KVM systems
or IP-based systems are up to the
task, although most digital systems,
including digital IP-based systems, can
support fast, HD video.
Responsiveness: Test keyboard and
mouse setup to make sure there is no
latency. A true USB emulation KVM
switch is responsive and consistent;
an unresponsive K/M jars the operator
out of his/her workflow.
Productivity: In a matrix setting,
all resources and displays can be
connected and switched between
by multiple users. Collaboration
is enhanced by the ability to view
and control the same resources
simultaneously.

Accessibility:
Calculate
the
longest distance
between your
endpoints, and
make sure the
KVM system can work over CATx or
fibre cabling - or a mix of both - to
reach all your targets. With digital
matrix KVM systems, multiple users
should have real-time access to
targets.
Reliability: New generation KVM
systems will support redundancy
options such as multiple power supply
units for 24/7 uptime. Make sure the
system you select can support routing
transmitters and receivers through
two separate core KVM switches for
full redundancy.
Speed: Many digital KVM switching
systems
support
video-switching
speeds of under a half second.

A typical KVM application for
broadcasting

Anything
longer
interrupts
an
operator's workflow as he or she
switches between resources and may
be noticeable to a viewer.
Security: KVM switching and
extension systems need to be secure.
Be sure administrators can assign
specific access rights to specific
resources.
Remote
configuration
and maintenance of the KVM system
enables an admin to securely log onto
a system.
When you can mark off all eight
of these categories, you'll have
maximised your ROI.
