The KVM Matrix-Grid™, a feature of the digital KVM matrix switches from Guntermann und Drunck GmbH, helps users implement even more complex and powerful IT installations. The matrix grid establishes bidirectional communication between individual matrix switches. Now it is even easier to interconnect systems and facilitate larger installations. Thus, users are able to operate the system bidirectionally at multiple locations and access the remote IT systems of the remote matrix. The individual matrix systems are connected via gridlines, which are direct connections of the I/O ports from one system to another. But what about the cabling effort and how can it be reduced without compromising the performance of the systems?

Reducing the number of grid lines with the I/O-Card-Trunk4

G&D’s I/O Card Trunk4, which can be placed in one of the I/O  slots of the ControlCenter-Digital matrix system, provides an answer to this question. The I/O-Card-Trunk4 reduces the grid lines required for a matrix grid by combining 4 of the 16 channels on one line. For transmission between two matrices, the four ports of an I/O-Card-Trunk4 can be configured independently for a 1:1 direct connection. Transmission between two I/O-Card-Trunk is carried by even more powerful components compared to the standard. These components let you use the fourfold of the bandwidth at the same time – thus saving you one fourth of cabling efforts.

Reducing cabling efforts even further?

In addition, the I/O-Card-Trunk4 supports a connection over a 10 Gbit/s Ethernet network (layer 2). The transmission mode (G&D protocol or Ethernet) can be set individually for each of the four transmission ports. This means that efficient network infrastructures can also be used, and the cabling does not necessarily have to be done in a dedicated manner. Matrix grid installations can even be set up across locations if suitable connections are available. This way, long distances can be bridged and even studio locations can be connected with each other. The KVM Matrix-Grid™ over Ethernet does not only make it easy for admins to access the system, but also allows access to multiple users from different locations.

With the I/O Card Trunk4, G&D provide their customers with a powerful tool to implement complex, bi-directional matrix grid installations even easier. By bundling four channels on one line, the cabling effort is significantly reduced. Thanks to the Ethernet capability of the I/O-Card-Trunk4, even existing infrastructures can be used.
