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!)

Summary
• Cloud services need DC connectivity
� the network becomes a strategic asset
• T-SDN brings programmability,
virtualization & multi-tenancy
to optical networks.
• A programmable, open optical layer
is key to future-proof DCI solution
