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 Ethernet Overlay One Logical Data Center Automatic Fault Isolation
