When Interxion decided to expand its operations in Marseille, real-estate and power constraints led the company to build a second data center two and a half miles from the original site, and connect the two facilities with a super-fast Data Center Interconnect (DCI) network. This allowed Interxion to create a single virtualized data center campus, giving its clients light-speed access to subsea cables, platforms, connectivity providers and other partners at both sites.
