The enterprise isn't yet equipped to deal with the consequences of SDN, because no one knows what those consequences will be.

The Road to the Cloud Runs Through the Network

Advanced cloud architectures will require advanced network infrastructure in the data center.

Ethernet Faces High-Bandwidth Growing Pains

The road to 100 Gbps+ Ethernet is proving more complicated than it first appeared, at least for those considering hyperscale deployments.

Should the Fabric Have a Core? Perhaps for a Little Longer

Network fabrics imply a flattened architecture that eschews centralized switching. So why are vendors still talking about core fabric switches?

Hyperscale Networking: Coming to a Data Center Near You?

Hyperscale implies massive infrastructure, but key technologies may wind up in standard enterprise settings as well.

Open vs. Proprietary SDN: New Technologies, Same Old Dilemmas

Even with the advent of highly fluid virtualized data environments and SDN, choices like open vs. proprietary remain.

SDN Still Has to Prove Itself to the Enterprise

SDN must overcome several key challenges before it can make it through the hype cycle and establish itself on the other side.

PCIe 4.0—or perhaps Nvidia's PCIe alternative—holds the potential to transform data infrastructure on a micro level.

Cisco, ACI, SDN, and the Commodity Networking Challenge

Enterprise interest in commodity hardware for SDN threatens the dominance of proprietary hardware vendors like Cisco. How does ACI address the problem?

Networking for Converged Infrastructure

Converged infrastructure is great for plug-and-play provisioning, but first you have to decide what kind of network you want.

The Dynamic Cloud Needs the Software Defined WAN

To build a multi-site data ecosystem, the enterprise needs to push SDN past the edge. The software defined WAN is coming.

The Big Picture: SDN and the Dynamic Data Environment

Far from a simple networking play, SDN is poised to rewrite the entire data infrastructure paradigm.
