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
