We stand on the cusp of the next technological revolution. The forces of cloud, big data, mobile and security are changing the way people live, businesses operate and the world works, just as the PC did. Now it’s time to do what Dell does best—make these innovations simpler, more affordable and more accessible, putting more power into the hands of more people than ever before.

What is SDN (Software Defined Networking)? • According to Open Networking Foundation
SDN is a new approach to networking in which network control is decoupled from the data forwarding function and is directly programmable.
The result is an extremely dynamic, manageable, cost-effective, and adaptable architecture that gives administrators unprecedented programmability, automation, and control.

Cloud goes beyond the hype
Enterprise cloud application revenues reached $22.9B in 2011 and is projected reach$67.3B by 2016.
60% of server workloads will be virtualized by 2014.
Global cloud traffic will account for nearly two-thirds of total data center traffic by 2016.
Currently 46% of business data is stored outside of internal IT structures.
Over the past three years nearly 74% of data centers increased their physical server count.
IaaS cloud management & security and PaaS are growing from $7.6B in 2011 to $35.5B in 2016.
Projected Market Spend of
$241 Billion by 2020
68% of spending on private clouds
Public
- Bain and Dell
85% of organizations will use cloud tools moderately to extensively in the next 3 years.

What Enterprises IT departments Contend With Today
• Lack of infrastructure standardization and automation leading to poor resource utilization, cost escalation, slow application delivery
• Locked-in to proprietary vendors and technologies – increasing license costs with growth and scale
• Poor understanding of cost allocations
• Long resource provisioning cycle times
• Inflexible and non-adaptive infrastructure
• Building a cloud is too complex and takes too long
• Lack of availability and support of the entire solution

How Active Fabric Controller Works Forwarding
Supervisor controls protocol behavior & coordinates FDB synch between modules
Learns mac addresses as standard Ethernet learning bridge
Traditional Modular Chassis
• Mac addresses learned as packets sent • If distributed forwarding, supervisors
synch FDB between modules • In older chassis and primitive systems
such as Cisco FEX/UCS, ALL packets must pass through supervisor/FI
Flow tables pre-populated with host data from OpenStack for optimal performance & security
• Macs learned from OpenStack and prepopulated into flow tables for performance & security
• During flow/policy modification, controller populates end-to-end path
• In standard operation, no packets wait on controller
Active Fabric Controller
When flows or policy needs modification, controller populates end-to-end path

• No fixed wiring • Network virtualization • Optimized path setup • HA and Resiliency

• Traffic steering, TAP/Span • Fine-grain policy control • L4-L7 service insertion
