DE-CIX Apollon: Implementing Alcatel-Lucent’s 7950 XRS-40 Daniel Melzer (Manager Network & Data Center, DE-CIX) I had two babies in 2013... 1st: September 28th 2nd: December 4th DE-CIX Apollon » Biggest Hardware Replacement and Toplogy Redesign ever » Planning and Implementation took more than 2 years (and some sleepless nights) » Finished in December 2013 » Only thing left: » Transformation of four 7950 XRS-20 in DE-CIX 6 and DE-CIX 7 into two 7950 XRS-40 » This has been done in the last two weeks Agenda » What is Alcatel-Lucent 7950 XRS-40 » Why do we use it? » Movie clip from the Installation » 7950 XRS-40 Technical Deep Dive » Greg Hankins (Alcatel-Lucent), live from New York What is Alcatel-Lucent’s 7950 XRS-40? » Implementation based on 7950 Service Router » Single system provides up to 800 10GE-Ports or 80 100GE-Ports or a mixture » Nice, but the interesting thing is hidden in the back What is Alcatel-Lucent’s XRS-40? » Implemented as Back-to-Back, not via dedicated matrix shelf » Switch fabrics of two 7950 XRS-20 are interconnected into a single node » using 8x14 multi ribbon fiber interconnects between the shelves » Providing more than 13Tbps of interconnect capacity » Doubles system capacity from 8Tbps to 16Tbps (using recent linecards, available today) Why are we implementing 7950 XRS-40? Elegant implementation to cater for increasing bandwidth » Allows more customer ports on the edge nodes » Traffic local to a site should be ideally switched on a local edge node, instead of multiple edge nodes traversing the core nodes » Economically beneficial through stretching regular upgrades that would have been required across the whole platform » No compromise on resiliency and stability Implementation plan » Successfully tested in POC in Alcatel-Lucent Labs by DE-CIX staff » XRS40 upgrades in sites DX6 and DX7 in October 2014 » XRS40 upgrades in sites DX2 and DX9 planned for late 2014, early 2015
