But…

Virtual Machine concept:

server and storage virtualization across hardware boundaries

Server virtualization needs a more dynamic and flexible network

New applications for dynamically moving workload to another data center (e.g. VMotion, Site Recovery Manager) require more deterministic, scalable, on-demand performance and management – i.e a flatter Layer 1/2 network
