  1. Evolution of the Data Center Avaya Networking

  2. Applications Are Changing Transition from Client/Server to Web 2.0 & Cloud…

  3. Devices Are Changing Almost nothing in common, except that they’re all different…

  4. Roles Are Changing The traditional workplace is disappearing…

  5. People Are Changing Expectations are different, expectations are higher…

  6. Change Is Pervasive; So Too The Network With change pervasive, the network cannot be immune… • Tomorrow’s application requirements are so different from yesterday’s • Traffic patterns are evolving with the emergence of mobile, video, & embedded • Why then, do most vendors offer products and solutions that are geared, and can only be deployed, as if nothing has changed..?

  7. Compute Access ≠ User Access Consolidation & Chaos Theory combine into a perfect storm… • Data Center presents is a very different scenario to the Wiring Closet • It's virtually unknown for Desktop ports to operate anywhere near line-rate • Top-of-Rack Switch: it is altogether feasible to talk of Servers running 10 Gigabit ports at or near line-rate

  8. “By 2014, network planners should expect more than 80% of traffic in the Data Center's local area network to be between Servers.” Your Data Center Network Is Heading for Traffic Chaos Gartner

  9. Evolution of the Data Center Once, Campus-class was good enough • What this meant: • Application traffic traverses multiple Switch hops – Access- Core-ToR-Server-Core-Access • Core & Uplinks were more important than capacity between Racks Traditionally: The North-South to East-West ratio has been 80:20 Top-of-Rack Switches Racked Servers

  10. Avaya Distributed Top-of-Rack Delivering the Cloud-grade difference • Now this means: • Server-to-Server, Rack-to-Rack traffic dramatically increases • Inter-Rack capacity is now crucial • Traditional designs introduce significant latency and degrade application performance The future: East-West traffic will dominate Data Center traffic – ‘the new 80%’ Top-of-Rack Switches Distributed ToR delivers the industry’s only low-latency solution Alternatives introduce latency & congestion, additional equipment, consume more ports Racked Servers

  11. Avaya Data Center Solutions Next-generation solutions for next-generation challenges Fabric Connect Core VSP 9000 North-South / Core-ToR Interconnects VSP 7000 Distributed Top-of-Rack

  12. Which Fabric Technology is the Answer..? That all depends on how you qualify the question… Application Awareness Avaya Extensions Avaya VENA Fabric Connect • Aspirational Functionality, but • It requires: • BGP • LDP • RSVP-TE • Draft-Rosen • VPLS • Service-based Virtualization • Infrastructure Abstraction • Orchestration-ready • Single Logical Fault Domain • 100m Distance Limitation • VLAN-based Virtualization • Root Bridge–Dependent • Large Flooding Domain • VLAN-based Virtualization • Baseline Redundancy • Root Bridge –Dependent • Arbitrary Path Selection • Layer 3 Awareness • Unicast & Multicast • Application-driven Extensibility • SDN-ready L3 Multicast Virtualization IETF MPLS L3 Unicast Virtualization L2 Multi-Site Virtualization IEEE SPB – Multi-Vendor L2 Single-Site Virtualization IETF TRILL Cisco FabricPath Brocade VCS Juniper QFabric L2 Multi-Pathing L2 Loop-free Topology STP

  16. Empowering the Cloud Mapping of Layer 2 VLANs into Virtual Service Networks delivering seamless Layer 2 extensions Layer 2 Virtual Service Networks Virtual Service Network Mapping of Layer 3 VRFs into Virtual Service Networks delivering seamless Layer 3 extensions Layer 3 Virtual Service Networks Virtual Service Network Policy-based Layer 3 internetworking capability between multiple Virtual Service Networks Inter-VSN Routing Virtual Service Network Virtual Service Network Direct IP Routing withoutthe need for Virtual Service Networks (or any additional IGP) IP Shortcut Routing VLAN VLAN

  17. Use Example: Virtual Machine Migration • Mapping a Layer 2 VLAN into a Virtual Service Network to deliver seamless extension across the Data Center Layer 2 Virtual Service Network Business Requirement: • Provide direct end-to-end connectivity at Layer 2 between applications running on multiple servers • Facilitate live migrations to support application scaling and hardware support & maintenance • Span L2 connectivity throughout the Data Center, and across multiple locations • With Fabric Connect: • Application VLANs mapped into unique VSNs • VSNs extends L2 connectivity across the Fabric • Provisioning only at Fabric edge • Mitigates: many touch points for configuration, management, & troubleshooting, Broadcast domain seen at all points through the network, lack of traffic isolation

  18. Use Example: Wireless Guest Services • Mapping a Layer 2 VLAN into a Virtual Service Network to deliver seamless Wi-Fi connectivity across the campus Layer 2 Virtual Service Network Business Requirement: • Provide Wireless Guest Access in specified locations throughout the Campus • Ability to quickly add / remove Guest Access from certain locations within the Campus • Guest traffic must be isolated from internal network traffic • Authentication of Guests required for compliance and security tracking • With Fabric Connect: • Wireless Guest VLAN mapped into VSN maintains traffic separation • Layer 2 VLAN extension across the Fabric • Provisioning only at Fabric edge • Mitigates: many touch points for configuration, management, & troubleshooting, Broadcast domain seen at all points through the network, lack of traffic isolation

  19. Use Example: Multi-Tenant Networks Layer 3 Virtual Service Network • Mapping a Layer 3 VRF into a Virtual Service Network to deliver seamless Layer 3 extensions through the network Business Requirement: • Provide infrastructure to support multiple different customers (airport, education, government) • Maintain traffic separation between customers for data integrity & security • Offer dynamic network to accommodate geographic location changes for network connectivity • Share common resources where applicable (e.g. UC) • With Fabric Connect: • VRFs create traffic separation which is maintained through VSN • Extends Layer 3 VRFs across the Fabric • Use of shared services becomes simple and efficient • Mitigates: complexity of configuration, difficulty in providing resiliency, excessive equipment

  20. Use Example: Workgroup Networks • Extending SPB by delivering a policy-based Layer 3 internetworking between multiple Virtual Service Networks Inter-VSN Routing Business Requirement: • Provide network access for a common set of users (department, agency, contractors, etc.) • Maintain traffic separation from the rest of the network • Offer connectivity between this common set of users and applications that reside within the Data Center • No desire to extend VLANs across Campus to achieve this • With Fabric Connect: • Workgroup able to communicate with each other and applications • Traffic separation is maintained through VSNs • Security without the need for complex ACLs or separate hardware • Mitigates: many touch points for configuration, lack of isolation of traffic

  21. Use Example: Business Collaboration • Direct IP Routing across the Fabric without the need for any additional IGP or even Virtual Service Network configuration IP Shortcut Routing Business Requirement • Deploy new business collaboration services to provide high definition desktop video capabilities • Simplify and optimize deployment across network infrastructure • Ensure proper quality of service to provide acceptable user experience • Reduce troubleshooting complexities associated with existing environments • With Fabric Connect: • Route directly across the Fabric with IP Shortcuts • No need to configure and IGP on any VLANs • Policy allows redistribution control of IP routing over Fabric • Mitigates: complexity of configuration, difficulty in providing resiliency, lack of isolation of traffic, providing appropriate quality-of-service
