Pressure Mounts for 100G in the Data Center

The pressure is on for high-bandwidth networking in the data center, but is 100G worth it to the enterprise?

The Brave New Application Delivery Environment

Improved application delivery is the ultimate goal of technologies like SDN and virtualization and should be the ultimate goal of the enterprise data center.

The Slow and Steady Route to SDN

SDN doesn’t have to involve a rip and replace. Overlay networking, open switching formats and open source support a more gradual transition.

Is It Time for the Data Center to See the Light?

Optical cabling is on the rise in the data center. What challenges will fiber bring to the enterprise?

2015: A New Year and a New Network

2015 will see SDN deployments kick off in earnest, but that’s not all that lies in store for enterprise data center networking.

Preparing for the Application-Driven Data Center

The application layer looks set to become a major focus for IT. Here’s a look at what to expect and how to plan for the app-centric future.

New Tools for the Distributed Data Center

Advances in taking the SDN to the WAN are bringing enterprise data environments closer to the dream of a fully federated, distributed cloud ecosystem.

SDN and Cloud Connectivity in Distributed Data Environments

When it comes to SDN and the cloud, optimal connectivity will involve more than just bandwidth and throughput.

SDN and Big Data: Enterprise, Analyze Thyself

Big Data and SDN are more than just mutually beneficial. In fact, in the data environments of the near future, they will need each other.

ARM Solutions for the Data Center Network

ARM architecture looks capable of better serving mobile, cloud, virtualized, and software defined networking needs. Some vendors are already taking advantage.

Don’t Skimp on Cloud Connectivity

"Inadequate networking could make your cloud more of a hindrance than a help to next-generation data functionality."

Containers and the Virtual Network

What issues could containers cause in a virtualized network, and what are vendors doing to address them?

SDN Deployment: Managing the Pace of Change

As enterprises take their first steps towards SDN, how should they manage the transition for best results?

SDN: Unshackling the Network Application Environment

What will be the killer app for SDN, and does there have to be only one?

An SDN for Every Market

Handicapping the growth of the SDN market is a tricky game. But whether you are SME, SoHo, or hyperscale, there is a software defined network out there for you.

Looking Past SDN to the Cloud

Technologies like the software defined network evolve within the confines of wide industry trends. These days, that would be the cloud.

Visibility and SDN: You Can't Manage What You Can't See

SDN's flexible, dynamic nature creates new network monitoring and visibility problems. Here's what networking vendors are doing to solve those problems.

Hardware Customization in a Software-Driven Universe

Programmability will bring unprecedented flexibility to the software defined network, but what about customizing the underlying hardware?

Networking in a Changing Data Environment

Just as networks take their first steps into virtual infrastructure, the data environment and its requirements are changing again.

Networking, Private Cloud, and the Heterogeneous Environment

Some networking vendors aim to unify multi-vendor, legacy data center silos into the interoperable environments private cloud requires.

SDN Makes VDI a TCO Game-Changer

Network virtualization and SDN are finally making VDI viable for the enterprise. Art Cole discusses where it will work best.

Working Toward the Wide Area LAN

Increasing reliance on the cloud is making the WAN critical to enterprise connectivity. Vendors are stepping up to deliver LAN-like functionality for the WANs of the future.

First SDN, Then the Intelligent Network

What are the practical benefits of intelligent networks, and how does network intelligence differ from SDN?

What's Holding Data Center Performance Back?

Data center spending often focuses on performance improvements. But what are the real culprits behind poor performance, and how can you fix it?

SDN: It’s All About the Apps

SDN application development efforts look set to increase the capabilities and value of software defined networks in the enterprise.
