The corporate data center is undergoing a major transformation the likes of which haven't been seen since Intel-based servers started replacing mainframes decades ago. It isn't just the server platform: the entire infrastructure from top to bottom is seeing major changes as applications migrate to private and public clouds, networks get faster, and virtualization becomes the norm.

All of this means tomorrow's data center is going to look very different from today's. Processors, systems, and storage are getting better integrated, more virtualized, and more capable at making use of greater networking and Internet bandwidth. At the heart of these changes are major advances in networking. We're going to examine six specific trends driving the evolution of the next-generation data center and discover what both IT insiders and end-user departments outside of IT need to do to prepare for these changes.

Beyond 10Gb networks

Network connections are getting faster to be sure. Today it's common to find 10-gigabit Ethernet (GbE) connections to some large servers. But even 10GbE isn't fast enough for data centers that are heavily virtualized or handling large-scale streaming audio/video applications. As your population of virtual servers increases, you need faster networks to handle the higher information loads required to operate. Starting up a new virtual server might save you from buying a physical server, but it doesn't lessen the data traffic over the network—in fact, depending on how your virtualization infrastructure works, a virtual server can impact the network far more than a physical one. And as more audio and video applications are used by ordinary enterprises in common business situations, the file sizes balloon too. This results in multi-gigabyte files that can quickly fill up your pipes—even the big 10Gb internal pipes that make up your data center's LAN.
