The document discusses how networking in data centers must fundamentally change to adapt to virtualization and growth in storage. Legacy physical networks are challenging to manage at scale and cannot keep up with modern demands, while next generation virtualized networks provide scalability, flexibility, and automation. The document argues that instead of replacing legacy networks, data centers need unified infrastructure management across computing, storage, and networking to efficiently orchestrate flexible infrastructure and realize performance and economic benefits.

•Fewer Ports – Higher Bandwidth
Fabric convergence, port proliferation, management sprawl & virtualization
forcing network management changes. Does that mean your legacy network
needs to be thrown out? How do we manage this change?
