  1. Data Center Design Using Avaya Fabric Connect Carl DeVincentis

  2. Evolution of the Data Center Once, Campus-class was good enough Traditional networks are designed for north/south traffic – ToR Switches interconnected by the Core or Aggregation… • 20-30 microseconds for every hop • Modern applications have an average of 8 transactions Rack 4 Rack 2 Rack 3 Rack 1

  3. Evolution of the Data Center Traffic Patterns were Traditional Traditionally: The North-South to East-West ratio has been 80:20 Top-of-Rack Switches Racked Servers • What this meant: • Application traffic traverses multiple Switch hops – Access / Core / ToR / Core / Access • Uplinks were more important than Inter-Rack capacity

  4. *Gartner, 2011 “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

  5. How to address the new traffic needs Distributed ToR Distributed ToR is specifically designed for east/west traffic – ToR Switches directly interconnected… • DToR costs just 1 microseconds switch hop Web VM Web VM App VM D/B VM

  6. Eliminate the bottlenecked uplinks Distributed ToR The future: East-West traffic will dominate Data Center traffic* – ‘the new 80%’ 20% Top-of-Rack Switches 80% Avaya delivers the industry’s only low-latency Distributed ToR solution Alternatives introduce latency & congestion, additional equipment, consume more ports Racked Servers * Gartner: ‘Your Data Center is heading for traffic chaos’ – April, 2011 • 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

  7. Scalability with Flexibility • Fabric Connect in the Data Center offers: • Architectural Flexibility • Small, Medium & Large data centers • Centralized and distributed • Layer 2 overlays with Layer 3 VRFs • Interoperates with non-Avaya platforms • Scale • Increasing L2 scale while decreasing L2 complexity and improving mobility • Distributed ToR utilizes multiple 40G uplinks • Eliminates the “choke points” of uplinks • Handles East-West traffic natively

  8. Two operational modes for true deployment flexibility Distributed Top-of-Rack Fabric-mode DToR Flexible Interconnect: up to 500 Switches (16,000 10GbE Ports & 280Tbps) Row A Stack-mode DToR Structured Interconnect: 8 Switches (256 10GbE Ports & 5.12Tbps) Row B Row C Row D From small to very large – D-ToR can handle it!

  9. VM Evolution – The Need For Scale & Flexibility Members of the same VM domain must remain in the same subnet Physical Servers Virtual Servers APPs I-P Per Rack APPs A-H Per Rack APP A APP B Rack 1 Rack 1 Rack 2 While application scale & server utilization is poor, network complexity is simple Server virtualization brings scale and efficiency to applications. VMs become essentially “jailed” and network flexibility is reduced. VM Mobility is seriously limited. What is the alternative…?

  10. VM Evolution – The Need For Scale & Flexibility • Fabric Connect provides the VMs & therefore, the applications a “get out of jail free” card • No longer bound by physical & logical constraints, VMs can be moved anywhere • This creates the flexibility to improve availability, simplify maintenance and enhance application expansion Row A Row B Row C Rack 1 Rack 2 Rack 3 Rack 4 Jailbreak..! Put your VMs where you need them..!

  23. Fabric Interconnect Stacking Benefits • Allows for Fault-tolerant or Load sharing NIC teaming into stack • Up to 8 units create a vToR (virtual top-of-rack) delivering up to 5Tbps using two FI cables in parallel between switches for a total of 256 10GE ports • Up to 16 units in a dToR (distributed top-of-rack) delivering up to 10Tbps using two clusters of 8 switches for up to 512 10GE ports • High bandwidth and low latency between servers (2.1µs – 5.3us) • Highly resilient stacking technology with scalable uplinks • Flexibility to spread across multiple data cabinets (100s of servers) • Ideal for Grid Computing/High-Performance Computing Solutions

  24. VSP 7000 Fabric InterconnectRear Port Speeds • The 4 physical Fabric Interconnect ports provide different bandwidth capabilities (see rear-ports feature for more details). • Three different colours are used to represent the different capabilities. Optimum performance will be achieved when ports of the same throughput are connected to one another. 38-40 34-36 37 33

  25. Fabric Interconnect Mesh • Rear Port Mode Standard • SPB is not supported when the rear port mode is set to standard (raw) mode • The IST must be made up of a minimum of two ports, i.e. use both rear blue ports or you could use either the red or black rear ports as each has 3 ports each • LACP must be disabled prior to enabling IST or SMLT using the rear ports • SMLT square and triangle topologies are supported in rear port raw mode; SMLT full mesh is not supported • Rear Port Mode SPB • Only SPB L2VSNs are supported • For routing, the L2VSN must be terminated on at least one VSP 9000, VSP 4000, or ERS 8800 that either has IP Shortcuts or L3VSN enabled; it is recommended to terminate the L2VSN on a second VSP 9000, VSP 4000, or ERS 8800 and use VRRP • The IST must be made up of at minimum two port, i.e. use both rear port blue ports or you could use either the red rear ports (2 ports) or black rear ports (3 ports) • Please note that one of the red ports is used as a SPB loopback port, hence, the number of ports is reduced by one
