Many physical sites - One logical Data Center
Layer 2 Ethernet Extension
Introducing Overlay Transport Virtualization Simplifying Data Center Interconnect
Ethernet LAN Extension over any Network• Ethernet in IP “MAC routing” • Multi -datacenter scalability
Simplified Configuration & Operation• Seamless overlay - No network re-design• Single touch site configuration• Provisioning Automation
High Resiliency • Failure domain isolation• Seamless Multi-homing
Maximizes available bandwidth• Automated multi-pathing• Optimal multicast replication
Any Workload, Anytime, AnywhereUnleashing the full potential of compute virtualization

Ease of Provisioning: Data Center Growth Constraints
•Problem Primary data center maxed out (space, cooling and power)
•Requirement Seamlessly extend clusters and workload across data centers
•Challenge Rapidly establish DCI between data centers
• No new transport provisioning required (Dark fiber, MPLS, etc)• Eliminate months of re-design effort • Significant operations and provisioning cost savings (no new protocols )
Solution: OTV – Establish DCI in 5 minutes!
Deploy over existing Network
4 configuration commands per site
No Re-design Required
