In computer hardware, a KVM switch provides userswith a greater range of device control. KVM is based on three words:
keyboard, video, mouse. The KVM hardware delivers the capability to manage
multiple computers, servers or other KVMs by using a single keyboard,
monitor or mouse. KVM switches connect computers together as permitted by
distance and port availability. Switch specifications tell users the number
of devices that can be accessed and controlled. For example, a four-way KVM switch allows
for the control of four computers using one set of peripherals.
Enterprise-level KVM solutions with
remote LAN management are available.
KVM Switches Offering Scalability
More advanced KVM switches are scalable devices that
support interconnections using a daisy chain or cascade method. The cascaded
or daisy-chained KVM can potentially support more than 500 computers or
servers. Each of these computers becomes accessible and controllable by a
user on one keyboard. There are KVM devices with 16 or 32 ports for higher
density. A rackmount KVM switch enables direct computer connections, while
also offering daisy chain architecture to control more than 250 components
through one keyboard, mouse and monitor. KVM switch technology in a console
is a comprehensive solution that supplies the KVM and the components for
control in one unit.
Virtual KVM Computer Software
Software can also act as a virtual KVM. Programs are
installed on network computers to generate a virtual keyboard and mouse
switch. This switch sets up remote access on multiple computers so a mouse
cursor can move across individual monitors. Comms Express reps can explain
further how physical KVM switches can work in the data centre, command desk
or small office.
