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
