Distributed Data Centers

Many physical sites - One logical Data

Center

Layer 2 Ethernet Extension

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, Anywhere

Unleashing the full potential of compute virtualization

Access Pod 2

• Clusters, VMotion require L2 extensions to go across access pods

• Improves Manageability

• Dynamic Annexation

• Portability & Expansion

Ease of Provisioning - 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

OTV at a Technical Glance

Ethernet traffic between sites is encapsulated in IP: “MAC in IP”

Dynamic encapsulation based on MAC routing table

No Pseudo-Wire or Tunnel state maintained

LISP: Location Identity Separation Protocol

Internet

Device IPv4 or IPv6 address

represents identity and

location

Today’s Internet Behavior Loc/ID “overloaded” semantic

x.y.z.1 When the device moves, it gets a new IPv4

or IPv6 address for its new identity and

location

w.z.y.9

Device IPv4 or IPv6

address represents

identity only.

When the device moves, keeps its IPv4 or

IPv6 address.

It has the same identity

LISP Behavior Loc/ID “split”

Internet

a.b.c.1

e.f.g.7

Only the location changes

x.y.z.1

x.y.z.1

Its location is here!
