Server virtualization and cloud computing are driving a shift in network architecture, creating new challenges for data center network architects. This change is pushing a network architecture to an access network primarily connecting users, and a data center network primarily connecting virtualized servers and associated storage and eventually the private cloud. This e-guide discusses the issues virtualization introduces into a network architecture and best practices to tackle these potential roadblocks. Uncover key steps you can take to successfully build a next-generation data center network.
