THE CHALLENGE!

How to differentiate?

fast & simple

SOLUTION?

Accelerate introduction of new services and functions Deploy new workloads Full stack Resource Automation Self Care and Self Provision capabilities using standard set of APIs

Reduce OPEX Reduce CAPEX More cost-efficient services

Centralized control of resources Holistic monitoring of services Resource optimization on a global vs site-specific scale

Architecture Simplification Cross boundaries/limitations of traditional network solutions No geographic restrictions (physical resilience, data replication)

SDN, NFV or BOTH ?? OUR VISION

SDN

• Separation of control and data, centralization of control and programmability of network

• Relocation of network functions from dedicated appliances to generic servers

• Campus • Data Center • Cloud

• Cloud orchestration and networking • Routers, firewalls, gateways, CDN, WAN accelerators, SLA assurance

NFV

• Service Provider Network

REASON FOR BEING

TARGET DEVICES

INITIAL APPLICATIONS

• Commodity servers and switchs • Commodity servers and switchs

SCALABILITY

Traditional Architecture Fabric Architecture

SCALABILITY

Fabric Architecture

▪ east-west, high-speed, low latency ▪ Non-blocking (no STP) ▪ L2 switching to allow vMove, FCoE ▪ Equal Cost Multi Path ▪ Flexible topology ▪ Fabric Performance arround n x Terabit/s

POD 1 POD 2

Point of Delivery (POD) Concept Basic Architectural Unit

Mesh topologies (multiple connections between switches) Optimizes latency and bandwidth EAST <-> WEST (server-to-server) Network scalability to support large number of servers
