4 TECHNOLOGY CHANGES IN DATA CENTER Application Web 2.0 SOA SAAS Compute Storage

5 THE MULTI-TIER LEGACY NETWORK IS A BARRIER The challenge Multi-tier legacy network Too complex Too slow Too expensive N Unnecessary layers add hops and latency Up to 50% of the ports interconnect switches, not servers or storage W Up to 75% of traffic E Spanning Tree disables up to 50% of bandwidth S

6 LIMITS TO SCALE SCALABILITY: The ability to add capacity without adding complexity Limits of Scale Today s reality Capacity Capacity Complexity Ideal Scale

7 COMPLEXITY A FUNCTION OF DEVICES + INTERACTIONS Operational Complexity Number of managed devices Each switch is autonomous 7 managed devices Number of potential interactions Shared protocols 21 potential interactions Data Center N*(N-1) 2 N = no. of managed devices

8 COMPLEXITY A FUNCTION OF DEVICES + INTERACTIONS Devices Interactions ,000 Solve for the Too smallest ComplexN possible Complexity ,500 5,000 No. of Interactions = N = No. of managed devices N*(N-1) 2 Interactions 100 2,500 Managed Devices No. of Ports

9 CHALLENGES OF EFFICIENCY Up to 50% of the ports interconnect switches, not servers or storage Up to 50% of the bandwidth is disabled by spanning tree Too Expensive Up to 30% of the network spend can be avoided Eliminate $1B of annual spend world wide

10 STEPS TO A CLOUD READY DATA CENTER Policies Share Secure Infrastructure Simplify

11 Simplify

12 APPROACHES TO SIMPLIFICATION Better Tools Tools to manage the complexity Automation Hide the complexity Eliminate Complexity Design out complexity

13 SIMPLIFY THE NETWORK Consolidate devices Legacy Network Juniper High-Performance Network One Logical device Fabric Simplify Operations

14 DEFINING THE IDEAL NETWORK Flat, Typical any-to-any tree configuration connectivity

15 DEFINING THE IDEAL NETWORK Flat, any-to-any connectivity Single device N=1 Switch Fabric Switch Fabric Data Plane Flat single look up Any-to-any Control Plane Single device Shared state Simplicity of a single switch Single switch does not scale

16 DEFINING THE IDEAL NETWORK A FABRIC Flat, any-to-any connectivity Single device N=1 A Network Fabric has the. Simplicity of a single switch Network Fabric Data Plane Flat single look up Any-to-any Control Plane Single device Shared state Scalability of a network

17 DEFINING THE IDEAL NETWORK A FABRIC Two Tier Fabric One Tier Fabric A Network Fabric has the. Simplicity of a single switch Scalability of a network

18 SIMPLIFY THE NETWORK The legacy network, 3 tiers Ethernet Servers NAS FC Storage FC SAN

19 SIMPLIFY THE NETWORK Consolidate and virtualize appliances Ethernet Security Services Servers NAS FC Storage FC SAN

20 SIMPLIFY THE NETWORK Flatten Fabric at to access 2 tiers of tier switching Ethernet Access Tier Security Services Core Switches Servers NAS FC Storage FC SAN

21 SIMPLIFY THE NETWORK Edge Routers 2 Powerful edge services Ethernet Security Services Access Tier Core Switches Servers NAS FC Storage FC SAN

22 SIMPLIFY THE NETWORK Edge Routers 2 Fabric in the core Ethernet Security Services Access Tier Core Switches STP Servers NAS FC Storage FC SAN

23 FABRICS REDUCE COMPLEXITY Devices Interactions 10,000 7,500 At 6000 ports: 89% reduction in managed devices 99% reduction in interactions N*(N-1) 2 Interactions Complexity ,000 2,500 At 1000 ports: 83% reduction in managed devices 97% reduction in interactions Managed Devices Interactions with Fabric at Access Tier No. of Ports

24 SINGLE FABRIC: SIMPLIFY!!! Data center fabric, tomorrow N=1 Servers NAS FC Storage

25 SIMPLIFY THE NETWORK Consolidated Core Core Aggregation Access Access Eliminate the Aggregation Layer Simplify the Consolidated Core

26 EXPERIENCE AND ECONOMICS EXPERIENCE COST More Performance More Scalable More Agile More Secure More Reliable Lowest TCO 35% 25% 39% 44% CAPEX OPEX Power Space Juniper Legacy Source: Juniper s Financial Analysis Tool

27 SIMPLIFY THE NETWORK Access Single Scalable Fabric
