Bidirectional Switching
Enables Greater Flexibility
For Complex Infrastructures
Guntermann & Drunck's matrix grid expands the limits of infrastructure...

K

VM matrix systems make IT
infrastructures highly flexible by
allowing distributed access to a great
number of computers. To expand
the limits of this infrastructure even
further, G&D have developed the matrix
grid to link systems even more directly.
Not only does the matrix grid facilitate
the operation of large installations, it
allows the bidirectional operation at
multiple locations.
The matrix grid uses the features of
the dynamic ports provided at G&D
matrix switches: Each port can be
used as input or output and enables
bidirectional communication (See
Fig. 1). The ports are not only used to
connect computers and consoles, but
also serve to establish a connection
between individual matrix switches
thus allowing access beyond individual
matrices.

Until now, such connections could
be already established via cascades.
Unlike in classic cascades - which
are still possible as an alternative access from consoles to computers
is no longer exclusively top-down
in a tree structure. For this, the
database structure in the matrix
grid has changed substantially as it
now virtually summarises a system
of individual devices into one single,
large matrix.
Versatile Topologies
This means, from now on users
are no longer limited to the
classic cascade tree, but devices
can be interconnected as desired
depending on a given project. Here,
G&D once again put the focus on
the compatibility of their systems:
All digital KVM matrix systems -

Fig 1: Via the bidirectional connection, the G&D matrix grid allows access
across locations. When connected via optical fibres, locations can even be several
kilometres apart from each other and in addition to the classic cascade users of all
interconnected locations are able to access all systems connected.

ControlCenter-Digital and DVICenter,
in all sizes between 16 and 288 ports
- can be included in the matrix grid.
And the database provides only a
theoretical limit of a maximum of 24
matrices per grid.
Therefore, the G&D matrix grid
allows for highly complex
topologies to be set up in a
variety of ways, for example, as
strand, ring (See Fig. 2), star, or
as a fully meshed network (See
Fig. 3), or as a combination of
these topologies. Of course,
this wide range of possibilities
also
challenges
planners
and integrators to select the
optimal topology in each
individual case. But no matter
how challenging the task, the

Guntermann & Drunck's ControlCenter-Digital

Fig 2: Ring topologies, for example, support redundancy
concepts even better: Even if a connecting line or a node fails,
the system finds an alternate path for switching KVM signals.
Therefore, users benefit from always available installations,
especially in connection with other mission-critical
features provided by G&D.

Fig 3: The fully meshed network provides the maximum
of accesses between individual matrices.
For selecting the ideal setup, planners and integrators are
supported by experts from G&D. In the future application the
system automatically takes over the routing of KVM signals by
selecting the ideal path through the grid.

KVM experts from G&D are there to
offer advice and their experience from
30 years of developing KVM.
Customer Benefits
With the new matrix grid, customers
are able to establish even larger
installations, which they can use more
flexibly, for example, distributed over
several locations. Especially for critical
applications a fully redundant topology
provides further advantages in the
availability of all systems connected.
Now
further
failover
concepts
complement
the
mission-critical
features already provided by G&D.
The matrix grid also pays off from
the commercial side as large matrix
installations can be set up to optimise
the amount of required ports. Even
expansions of existing systems offer
potential for savings and easy ways
to combine devices for adding fibre
components on a broad basis to CATbased systems, for example.
Users, however, don't even realise
the complexity of the installation.
With the help of the G&D matrix grid,
they basically operate one large
system - and don't have to spend a
thought on its infrastructure. Yet, they
benefit from even more flexibility and
reliability: From their workplaces,
users can access all computers
connected to the grid no matter how
many there are.

G&D will demonstrate a matrix grid
installation on their Stand 1.B10 at
IBC this year.
