Convincing technology „Made in Germany“: WDM-System of Pan Dacom Direkt is increasing the performance and transmission range of the Mellanox MetroX Long Haul Infiniband Switches

The Mellanox MetroX Long Haul Infiniband Switches are the most cost efficient ones of its category.

In a test which has been initiated especially for the universities of Heidelberg and Mannheim in combination with the innovative WDM technology of Pan Dacom Direkt it was possible to increase the performance and the transmission range further.

For the test the Pan Dacom Direkt DWDM System SPEED-OTS 5000 has been connected to 2 Mellanox TX6100 Switches which can typically only be used for dark fiber links of up to 10 km.

The requirement for the test has been to install a stable InfiniBand connection via the significant higher distance of 28 km by also using a DWDM system. This is exactly the distance of the later needed transmission link between Mannheim and Heidelberg.

Due to the fact that the real test installation with a 28 km fiber drum looking like a supersize cotton reel which from the dimensions could fit in a wardrobe, the importance of the test result has been surprising.

The really impressing result has been that beside the expanded transmission distance it is possible to transmit 4x 10 Gbps via the DWDM connection with the option to expand the number of channels in future.

Beside of the flexibility of the SPEED-OTS-5000 it is also possible to transmit several 10 Gbps Ethernet and 4/8/16 Gbps Fibre Channel connections beside the 40 Gbps Infiniband via the same fiber link. Due to the protocol transparency of the WDM technology the transmission of the different data channels is fully independent of each other.

Thanks to the close collaboration of Pan Dacom Direkt and Mellanox Technologies the project could be closed successfully. Beside of the use of the latest technology also the local technical support teams as well as the remotely logged in R&D engineers lead to the described result.

“MetroX is the perfect cost-effective, low power, easily managed solution that enables today’s data centers to run over local and distributed RDMA Infiniband and Ethernet fabrics, with management under a single unified network infrastructure” said Gilad Shainer, Vice President of marketing of Mellnox. “In combination with the WDM-technology of Pan Dacom Direkt our switches are a powerful solution in many applications now” added Martin Roosen, Sales Director Central Europe at Mellanox Technologies.
