33. How to Evolve the Data Center
TRENDS
• Treat networking infrastructure like
servers
• High volume customers driving
hardware economics with ONIE
compliant platforms
REQUIREMENTS
• Ability to offer the industry’s most
capable networking software with
consumption models that fit varying
deployment needs
TRENDS
• Configure virtualized network real-
time to adapt to dynamic workloads
• Solutions bifurcated into customer
preference of standards based or
VMWare based
REQUIREMENTS
• Validated integration with
orchestration eco-system and
flexibility to create workflows
TRENDS
• New switching fabric architectures
require greater overlay scale for
interconnecting Data Centers
• Lean networking within the data
center, cost optimization driving 25 &
50GE
