Extending your data center reach with OTV and LISP Presentation Transcript

  • 1. Co-Sponsored by Intel® Extending Your Data Center Reach with OTV & LISP Brian Farnham Technical Marketing Engineer Cisco Systems, Inc. © 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 1 1
  • 2. Distributed Data Centers Distributed Data Center Goals • Seamless workload mobility • Distributed applications • Pool and maximize global resources • Business Continuity Interconnect Challenges • Complex operations • Transport dependant • Bandwidth management • Failure containment Presentation_ID © 2013 Cisco and/or its affiliates. All rights reserved. Geographically Disperse Data Centers Cisco Public 2
  • 3. Distributed Data Centers 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 Presentation_ID © 2013 Cisco and/or its affiliates. All rights reserved. Many physical sites - One logical Data Center Layer 2 Ethernet Extension Any Workload, Anytime, Anywhere Unleashing the full potential of compute virtualization Cisco Public 3
  • 4. Intra Data Center Layer 2 Networking End of Row V-Motion Clusters L3 L2 L2 Middle of Row • Clusters and VMotion operate well within L2 Clusters V-Motion • Build larger L2 networks for improved access layer load balance Presentation_ID © 2013 Cisco and/or its affiliates.

  • 5. Unbinding Vmotion and Clustering Access Pod 1 L3 L2 L2 • Clusters, VMotion require L2 extensions to go across access pods Access Pod 2 • Improves Manageability • Dynamic Annexation • Portability & Expansion Presentation_ID © 2013 Cisco and/or its affiliates.

  • 6. Live Migration of VMs from one DC to Another OTV Ethernet Extension Long Distance VMotion Data Center A Nexus 7000 Any Transport Data Center B Nexus 7000 This represents a significant advancement for virtualized environments by simplifying and accelerating long-distance workload migrations.

  • 8. 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 4 configuration commands per site One Logical Data Center Deploy over existing Network Ethernet Overlay No Re-design Required Automatic Fault Isolation Solution: OTV – Establish DCI in 5 minutes! • • • No new transport provisioning required (Dark fiber, MPLS, etc) Eliminate months of re-design effort Significant operations and provisioning cost savings (no new protocols ) Presentation_ID © 2013 Cisco and/or its affiliates.

  • 9. 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 IP packet Ethernet Frame MAC1  MAC2 MAC1  MAC2 IP A  IP B MAC IF MAC1 Eth1 MAC2 IP B MAC3 Encap MAC1  MAC2 Un-Encap MAC East Site Presentation_ID IP B IP A Communication between MAC1 (site 1) and MAC2 (site 2) © 2013 Cisco and/or its affiliates.

  • 10. LISP: Location Identity Separation Protocol Today’s Internet Behavior Loc/ID “overloaded” semantic Internet When the device moves, it gets a new IPv4 or IPv6 address for its new identity and location x.y.z.1 Device IPv4 or IPv6 address represents identity and location w.z.y.9 LISP Behavior Loc/ID “split” Internet x.y.z.1 Device IPv4 or IPv6 address represents identity only. When the device moves, keeps its IPv4 or IPv6 address. It has the same identity a.b.c.1 e.f.g.7 Its location is here! Only the location changes x.y.z.1
  • 11. Fixing Sub-optimal Routing • Layer 2 extensions represent a challenge for optimal routing • Challenging placement of gateway and advertisement of routing prefix/subnet WAN Ingress: North-South / Client-Server Ingress: North-South / Client-Server HSRP Filter HSRP Active HSRP Active HSRP Standby HSRP Standby East-West / Server-Server Egress: South-North / Server-Client Presentation_ID Egress: South-North / Server-Client © 2013 Cisco and/or its affiliates.
