End-to-end

Open source code, commodity hardware

• Completely customized solution

• Untested, not supported, time-intensive, hidden costs

Piecemeal

Solutions focused on individual domains

• Better support, validated

• Limited focus = limited benefit, cannot extend value

Holistic forklift upgrades

Singular system approach

• Unified approach across systems

• Rigid, risky, time-consuming, expensive

DIY

Dell can help you achieve your goals, on the path you choose

… which path is best for you?

Dell Networking

• Great Progress in 2013, let the momentum continue!

• Few remaining items - Organization & Training - Path to SDN

• Next SDN-SDS-SDDC-SDE

SDN Journey is now in implementation mode !

Thank you
