Webinar Content

Network architects typically use one of the following two traditional architectures when creating data center interconnect (DCI) solutions:

  • Layer-3 DCI: Each data center has its own address space; requiring renumbering of servers migrated between data centers. Live VM migration between data centers is not possible.
  • Layer-2 DCI: VLANs and IP subnets span both data centers to avoid renumbering and enable live VM migration. Both data centers become a single failure domain.

This webinar describes several hybrid solution based on Enterasys’ OneFabric architecture that enable address preservation when migrating virtual servers across robust layer-3 data center interconnects.

Challenges of Data Center Interconnects

This section will briefly revisit the challenges of traditional data center interconnect solutions, including:

  • Layer-2 connectivity requirements caused by stretched clusters or storage replication solutions;
  • Server renumbering or large stretched subnets (and failure domains);
  • Suboptimal ingress and egress traffic flows;
  • Inter-data center traffic trombones caused by server migration;
  • Stateful elements (firewalls, load balancers) in the forwarding path;

OneFabric Technologies

Enterasys’ OneFabric architecture includes numerous technologies that we significantly simplify the design of robust data center interconnects. This section will describe the most important ones including:

  • Shortest-path bridging (SPB) you can use to build large layer-2 fabrics;
  • Fabric Routing that optimizes egress (server-to-fabric) traffic flow;
  • Host Routing that optimizes ingress (fabric-to-server) traffic flow;
  • Data Center Manager that automatically migrates network-side policies after VM moves within or across data centers.

Final part of this section will describe future enhancements of the OneFabric architecture (including SPB-over-GRE) that will enable seamless integration of end-to-end layer-2 connectivity with layer-3 underlay transport.

Case Studies

The final section of the webinar will describe typical OneFabric DCI use cases and combine OneFabric components with overlay networking, virtual appliances and virtual firewall solutions. It includes the following case studies:

  • Optimal ingress and egress traffic flow in traditional layer-2 DCI environment;
  • Layer-3 DCI solution that enables disaster avoidance or service migration without server renumbering;
  • Disaster avoidance/recovery solution in combination with virtual firewalls;
  • Highly mobile cloud environment utilizing overlay networking (VXLAN/NVGRE) in combination with cloud orchestration and virtual appliances ... powered by robust OneFabric transport infrastructure.

Target Audience

If you’re a network architect, designer, or presales/support engineer working in data center environments, you simply must attend this webinar – all you need is baseline IP routing knowledge; awareness of server virtualization technologies is a bonus.
