Recently, in an Analyst Briefing …
Stephan, this Data Center
Interconnect (DCI) hype …
Isn’t DCI what you (ADVA)
have always been doing?

Optimized for highest availability, lowest latency and maximum security
• BC based on geographically distributed
server clustering and synchronous
data mirroring
• Technology-specific protocols:
10/40/100 GE, 8/16G Fibre Channel,
InfiniBand, FICON
• Conformance & qualification
• Moderate distances 10-150km
• Very stringent latency requirements
• Security matters!

How to Organize Data?
• Centralized Databases • Distributed Databases
Distributed data bases need more networking capacity

If Your Server Cluster Should Act as One
You are spending 85% on 15%
of your problem, and 15% on
85% of your problem.
(In other words, spend more
on transport!)
